1. When is ginger sown in my season? Answer: Ginger can be sown in our district from January to April. Generally speaking, in the suitable sowing period, sowing earlier, the growth period of ginger is longer and higher yield can be obtained. If sowing is too late, the growth period of ginger is too short, and the yield will drop significantly. Therefore, it is more appropriate for ginger to sow in our land in early March and early April. The farmland once had the “Chanming Shantou, Gu Yu Jiang.†This is the reason. 5, the kind of ginger block incision some fresh plant ash. 7. How does germination of ginger grow? Answer: Germination of ginger can be done as follows: 1. Warming material hotbed germination: Choose a leeward sunny plot, dig 1.2--1.5 meters deep, 0.4-0.5 meters deep, depending on the amount of ginger, the length of the concave bed (in order to east and west as well), bed The bottom is covered with a layer of 0.2-meter-thick fresh pig cattle manure, wetted with water and firmly pressed down, covered with a fine layer of 0.05 m thick fine soil, and the disinfected ginger is discharged into the bed in sequence. With the head facing upwards, a layer of straw is placed on top of it and it is sealed with a film to keep it moist. About 10-15 days of ginger grows. 12.

2. What varieties of ginger are currently cultivated in our country?
A: The ginger varieties I cultivated at present mainly include: local ginger.
3. What is the sowing rate of ginger? Kind of ginger block is appropriate?
Answer: The seeding rate of ginger is generally 150 kg per mu, because the size of ginger ginger has a significant effect on the yield of ginger. In a certain range, the bigger the ginger is, the higher the yield is, and the so-called "Big profits." Ginger is generally suitable for 50-80 grams, too small will affect the growth of the population, reduce production, if it is too large, it will cause high seed use and increase costs.
4. What are some links that should be paid attention to before ginger sowing?
Answer: The ginger should pay attention to the following steps before sowing:
1. Fine selection of ginger seeds;
2, ginger disinfection;
3, ginger seed germination;
4, ginger cut points.
5, how to select ginger seed?
Answer: Before ginger sowing, ginger must be carefully selected. Choose a large, thick and thick vegetative bud. The head is blunt, the fresh color of the epidermis is yellow, the ginger is bright yellow, the texture is hard, does not shrink, does not rot, is not affected by freezing and disease-free. Insect hazards and mechanical damage to the robust ginger block for ginger seedlings.
6. What are the methods of disinfecting ginger? how to proceed?
A: The methods for disinfecting ginger are:
1. Soaking seeds with Bordeaux 1:1:120 for 20 minutes;
2, soaked with 600 times the carbendazim 15 minutes;
3, soaking seeds with 1000 times permanganate for 10 minutes;
4, with 4000 times agricultural streptomycin soaked for 12 hours;
2. Insulation for indoor heat preserving: In the room, choose a sunny place. Spread a thick layer of straw on the ground and discharge the disinfected ginger in sequence. The ginger buds are topped with a layer of straw and covered with a thin film. Good heat preservation and moisturizing, about 20-30 days of ginger germination.
8, how to cut ginger nuts?
Answer: The cutting of ginger seeds should be carried out before sowing. The ginger seeds that will give rise to buds will be weighed in the order of 50-80 grams per piece, cut from the base, and graded according to size. - 2 strong buds, the rest of all erased, the incision with fresh grass ash ash, can help the incision heal, to reduce the purpose of the disease.
9, how to cultivate healthy ginger seedlings?
Answer: Cultivating strong seedlings is the first step in obtaining high-yield ginger. Only robust young shoots can grow strong seedlings, laying a good foundation for the vigorous growth of plants and achieving high yields. To cultivate a healthy ginger seedling, we must pay attention to the following aspects:
1. Strictly select ginger seeds;
2, ginger to be disinfected;
3. Germination of ginger
4, the weight of ginger block should be more than 50 grams.
10. How to choose a ginger plot?
Answer: Ginger is very adaptable to the soil and can grow well whether it is sand, loam or clay loam. However, different soils have a certain influence on the yield and quality of ginger. Therefore, the ginger plots should be selected for their high topography, convenient irrigation and drainage, deep soil layer, loose and airy soil, and rich organic matter content, and they are slightly acidic loamy soil. In addition, the field crops of ginger, sorghum, sweet potato, potato, tomato and other crops have not been planted for at least 2 years. The best choice is habitat. If it is a place of origin, it should be 1-2 months in advance. Deeply cultivating the sun can effectively improve the physical and chemical structure of the soil, reduce pests and diseases, and facilitate crop growth.
11. Why is it better to grow ginger than to grow ginger?
Answer: The habitat generally refers to those lands that have never been planted. Since no other crops have been planted, there are few pests and diseases, especially the devastating disease of ginger cultivation --- ginger aphid disease. Therefore, with a fertile land to grow ginger, ginger production is not only high, but also relatively good quality. The rehabilitated land is planted many years ago, and the pests are heavy and heavy, and even due to the severe occurrence of ginger borer, serious reductions in production are caused until the harvest is lost.
Answer: Ginger is a fertilizer and fertilizer-resistant crop, but its absorption of nutrients is different at different growth stages. Generally, it grows slowly, grows slowly, and absorbs less nutrients during the seedling period. When you enter a strong growth, the absorption rate increases rapidly and the absorption increases. According to measurement, for every 1000 kg of fresh ginger produced, about 6.34 kg of nitrogen, 0.57 kg of phosphorus, 9.27 kg of potassium, 1.3 kg of calcium, and 1.36 kg of magnesium are absorbed. If the phosphorus is 1, the ratio of nitrogen:phosphorus:potassium:calcium:magnesium is 11:1:16:2.3:2.4. It can be seen that during the whole growth period, ginger has the highest demand for potassium, followed by nitrogen, and once again magnesium, calcium and phosphorus. Therefore, in the cultivation, reasonable application of nitrogen, phosphorus and potassium fertilizers, especially potassium fertilizer, not only can increase the yield of ginger, but also the quality of ginger is good to achieve the purpose of high quality and high yield.
13. What is the density of ginger cultivation?
A: The density of ginger planting is large. It depends on the fertility of the planted land, the conditions of water and fertilizer, and the size of the ginger block. High soil fertility, good soil and water conditions, and 60 to 80 grams of ginger seedlings, 0.650.2 meters row spacing, that is about 5000 acres of planting; soil fertility and fertilizer conditions, moderate land, ginger The block is about 50 grams, and the row spacing is 0.60.18 meters, that is, about 6,000 acres of vegetation.
14. In the cultivation of ginger, what effect does this process have on the production of ginger?
A: Ginger belongs to the tuber crop. Its harvested products are mainly tubers, and the tuber growth of ginger needs to be in a dark and moist environment in order to grow well. Therefore, in order to obtain high yield of ginger, it is necessary to create a good environment for ginger's rhizome growth. The field management work in cultivation - soil cultivation, can not only create a dark and moist environment for ginger tuber growth, protect ginger, but also increase plant lodging resistance. Earthing work should be carried out continuously with the growth of ginger. Generally, the whole growth is carried out 2-3 times. The earthwork can be combined with top dressing and weeding at the same time.
15. In ginger cultivation, what is the effect of shading on ginger's growth?
Answer: Ginger is a negative-tolerance crop that is not tolerant of high temperatures, especially the seedling growth period of ginger. It is in the hot summer season. The temperature is high and the sun is strong. It is necessary to take appropriate shade measures to make Ginger seedlings grow well, otherwise it will easily lead to Dwarfing ginger seedlings causes a reduction in yield.
In the production practice, farmers in our land often plant ginger in the ginger field after sowing, so as to shade the seedlings after emergence. Mangosia grass not only has a shading effect, but also has a good permeability, which provides a very favorable environment for the growth of ginger seedlings and avoids grass shortages in ginger fields. By covering the grass, the ginger ground is placed in a dark and moist environment, which is conducive to the growth and development of ginger and tuber enlargement, thus obtaining higher yields.
16. What are the types of ginger harvesting?
Answer: The ginger harvesting methods include: harvesting ginger (ginger mother), harvesting tender ginger, harvesting fresh ginger.
Gathering Ginger: Different ginger and other vegetable crops, Ginger grows into a new ginger in the plant, the ginger is well-organized inside, no shrinkage and rot, can be recycled. Ginger harvesting can be performed together with harvesting fresh ginger, or it can be carried out early in the seedling growth period (before and after summer solstice), and attention should be paid to the protection of ginger seedlings.
Harvesting ginger: The harvest of ginger is performed during the vigorous growth period of the ginger plants. At this time, the ginger tissue is soft, with less fiber content, greater moisture content, and less spicy taste, and is suitable for processing such as pickling and candied fruit. However, the yield of harvested ginger is too low.
Fresh Ginger: After the November frost, ginger's shoots began to turn yellow and the tubers were fully inflated and matured on sunny days. The harvested fresh ginger should have a small amount of moist soil and be stored in the pit without drying.
17, how to prevent ginger rickets?
Answer: Jiangyan disease is also called ginger rot disease. After the ginger strain is infected by pathogens, both the stems and leaves or roots can show symptoms of damage. In the initial stage of root disease, it was immersed in water, yellow-brown, and dull. Afterwards, the internal tissues gradually softened, and only the outer skin remained. The squeezing diseased part could flow out of the grayish white liquid and smelled. The roots of ginger are also pale yellow-brown after being victimized and eventually rot. The above-ground stems were dark brown in color, and the stalk tissues were brown and rot, leaving behind fibers. Leaves withered and wilted after infection, and turned yellow from the bottom up, curled edges.
Prevention: 1, pay attention to crop rotation, especially in the ginger field for many years ginger, it is best practice for more than 4 years of rotation; 2, strict seed selection, eliminate hidden dangers of ginger; 3, the application of organic fertilizer should be fully cooked, ginger Fields should choose high-desert, well-drained and well-developed plots and sorghum cultivation; 4. Available for drug control: 1000-1500 times streptomycin for agricultural use at the beginning of disease; or 500 times for 30% copper citrate fertilizer; or 70% enemy liquid 600 times liquid irrigation control.
18, how to prevent ginger leaf blight?
Answer: Ginger leaf blight mainly damages the leaves of ginger plants, showing yellow and white leaf spots, spindles or oblong circles, small spots, length of 2--5 mm: the middle of spots is thin, easily broken or perforated. In severe cases, the spots are densely covered, and the ginger leaves resemble a star-like shape. Needle-shaped conidia can be seen in the diseased part. In the late stage of disease, the whole leaf of the diseased plant withered and wilted.
Prevention: 1, to avoid continuous cropping, the implementation of feasible circumstances, more than 2-3 years of rotation; 2, the best is not to grow ginger in low-lying land, ginger field should be selected high ground, drainage and irrigation convenient land; 3, pay attention to the reasonable ratio of fertilizer In the process of applying nitrogen fertilizer, phosphorus and potassium fertilizers should be applied, especially potassium fertilizer; 4 drug control 70% thiophanate-methyl 1000 times, or 75% chlorothalonil 1000 times, in the initial stage of the disease, the whole plant leaf spray control, Spray once every 7-10 days and spray 3 times.
19, how to prevent ginger anthrax?
Answer: Ginger anthracnose mainly damages the ginger leaves. When the disease occurs, the lesions appear first from the tips of the leaves and leaves. The initial appearance is water-soaked brown spots, and gradually expands into brown spots such as spindles or ovals. Large patches of disease make the leaves brown and dry. When the air is wet, there are many black spots on the diseased surface, namely conidia.
Prevention and cure: 1. Strictly implement the rotation system for more than 2-3 years; 2. Take farmyard fertilizers as the main, apply no nitrogen fertilizer, and apply N, P, and K fertilizers rationally; 3. Avoid ginger growers, and Jiang Tian cannot collect water; 4 Drug control can be used 70% thiophanate-methyl 1000 times, or 75% chlorothalonil 1000 times, or 30% copper oxychloride 300 times, in the early stages of the onset of ginger leaf foliar spray control.
20, how to prevent Jiangyan harm?
A: The ginger borers are also known as borers and corn borers. The adults are yellow-gray. The larvae are initially hatched in milky white and the mature larvae are pale yellow. In South China, 4- to 6-generation generations occur each year. The generation overlaps and the larvae hatch out. 2- - After 3 days, invaded ginger leaf sheaths, the damaged leaves became filmy, and there were residual dung debris on the leaves. The stems and leaves were often bitten into ring marks. The larvae hatched from the fourth to the sixth days, mostly in the stems. Upper foraging, resulting in hollow stems, impeded water transport, and the top of the ginger plants withered. Unripe mature larvae live on the stems of wild weeds. Adults are hidden in crops or weeds during the day and fly in the evening and mate at night.
Prevention and cure: 1. Thoroughly clean the ginger fields and burn them out in different places; 2. Manually capture larvae or trap insects to kill adult insects; 3. Use Trichogramma, acaricidal bacillus for biological control; 4. Drug control can be used to kill 50% Loose 500--600 times liquid, or 80% dichlorvos 1000 times, or 90% trichlorfon 1000 times, whole plant spray control.
21. How to prevent small tigers?
A: The adult tigers are dark brown and their larvae are gray and black. Their growth generation overlaps. It takes 6 generations per year in South China. Adults are active at night, mating and spawning, and eggs are produced on small weeds below 5 cm. , sugar, vinegar, wine, etc. have strong tropism. The 3rd instar larvae were not seriously harmed. After the 3rd instar, they were lurking in the soil surface during the daytime and they were harmful during the night. They bitten off the seedlings and caused seedling deficiency. Mature larvae have a feign death and are frightened into a ring. Small tigers like warm and humid environment. If there are many weeds and honey plants around the ginger field, it will cause serious damage.
Prevention and cure: 1. Remove the weeds in the fields to prevent spawning by the adult tigers; 2. Use insect traps, sweet and sour liquids to trap and kill adult worms; 3. Before the ginger sowing, the bitter beetles that can be eaten by young tigers , imperata, pupae and other stacked fields, trapping and killing larvae of small tigers; 4 drug control can be used 90% trichlorfon 1000 times, or 50% phoxim 800 times, or 20% 3000 mg of artyrifiate, or Killing and killing 8000 times the liquid, in the small tigers 1 - 3 instar larvae period, the whole plant spray control.
