There is a large area of ​​saline-alkali land on the eastern coast of China, along the banks of the rivers, and in the inland areas of the northwest, which accounts for about 1/4 of the country's arable land. Saline-alkali land planting is an effective way to make full use of saline-alkali land. Generally, less than 0.3% of paddy soil can be planted with salt. The key technology of saline-alkali land planting is to broadcast whole seedlings and prevent late-maturing greediness. I. Strive to broadcast a complete seedling 1. Water pressure salt, fertilizer and alkali on cotton fields with watering conditions, soaking and watering in the first two months before sowing, can play a role in washing soil salt. According to the salinity content of saline-alkali soil irrigation, the salt content of 0.1% to 0.3% should be 40 to 50 cubic meters/667 square meters of irrigation, when the salt content is high, the amount of irrigation should be increased. After irrigation and salting, the salt in the soil layer penetrated into the deep layer, which reduced the salt content in the soil layer. After watering, it is time to pick it up. Poor soil can easily induce salinity and must be treated first. Organic fertilizer can produce a large amount of acidic substances during the decomposition process, which can neutralize the alkalinity of soil and reduce the damage of sodium ions in the soil. At the same time, the decomposition of organic matter into humus can be combined with colloids in the soil to form a solid pellet structure, improve soil permeability, and improve soil fertility. Therefore, the saline-alkali planted cotton must be replanted, organic fertilizer should be applied more, and organic fertilizer must be applied year after year. General sowing before the site preparation of 667 square meters of manure, manure 3000kg, ammonium bicarbonate 50kg, phosphate fertilizer 50kg, laid the foundation for cotton production. 2. When the salt is separated by ridges, the soil salinity shifts with the water to the ridge back, so that the salinity at the bottom of the trench is reduced, and the seeds are sown at the bottom of the trench. . The ditching method has a 60cm ditch or a 100-cm ditch, and the width of the ditch is determined according to the degree of soil salt content. Heavy saline-alkali land should be wide, light salt alkali should be narrow. Use a mirror to plow open the ditches and then use a shovel to hold the soil between the two rafts. Use the width of the ditches to broadcast 1 to 2 rows of cotton. 3. Choosing good varieties; timely sowing of the cotton planting institutes No. 16, Zhongmiansuo No. 23, Zhongmian Soochows No. 35 etc. is currently suitable for the cultivation of saline-alkali land. In order to minimize the time that the cotton seeds stay in the soil and reduce the damage of the salt and alkali to young shoots and emerging seedlings, timely sowing should be carried out. The sowing date should be appropriate at the end of April and beginning of May. Before sowing, they are planted with pesticides to prevent pests and diseases. 4. After mulching with plastic film, the seeding and filming will be carried out at the same time after sowing. This will increase the temperature of the soil, keep the soil moisture, reduce the movement of salt to the roots of the cotton seedlings, and facilitate the seeding of whole seedlings. It is required to sow cotton seeds in the ditch or flat. The open field outside the mulching film must be ploughed before the film is uncovered, and the sloping soil layer of about 10 cm is often maintained, which will help increase soil water storage and reduce salt migration to the tillage layer. 5. Early seedlings, Dingmiao late, increase the density of saline-alkali land should be mainly to promote early-onset seedlings, early seedlings after emergence, late Dingmiao, with 3 to 4 true leaves Dingmiao as well. The increase in production of saline-alkali-planted cotton mainly depends on the population increasing the total number of peaches. Therefore, the density of saline-alkali-planted cotton and the number of plants at the time of harvest should be ensured, and generally 6,000 or more per 667 square meters. Second, to promote early-onset anti-late-ripening technology 1. The number of trees planted at 667 square meters was 6,000 at the early stage, and the number of fruit trees per plant reached 8 to 10, and the plant height was controlled at 50 to 60 cm. 2. Timely control of high density planted cotton control is a necessary supporting technology. Generally, it is chemically controlled 3 times during the growth period, and once more when necessary, the principle of light weight and heavy weight is mastered. Spray Dictamamine every 2 to 3 grams per 667 square meters, watered about 50kg. The bud period and flowering period are each once, and it is 4 to 5 days after the topping. According to the situation, the boll opening period can be determined. Late-maturity cotton fields can be sprayed with 3 to 4 grams of ghrelin per 667 square meters (50 kg of water). The use of ethephon ripening at the end of September to the beginning of October can increase the pre-frost flower rate and improve the fiber quality. 3. Strengthen field management After the emergence of cotton, apply organic fertilizer around it. Generally, cultivating in time after rainfall can ensure that salinization can be prevented. During the cultivating operation, the desalinated and weathered soil on the raft is reduced to the bottom of the ravine, and gradually increasing the soil around the ravine gradually turns the original ravine into a raft and a pupa into a ravine, which facilitates drainage. 4. Appropriately top-dressing top-dressing fertilizer should not be too large, and the time should be appropriately advanced. During the period of budding, 5kg/667 square meters of urea was chased, and 15kg/667 square meters of urea was harvested during the flowering period. At the same time potassium fertilizer can be added appropriately.
The goji berry is very healthy and therefore high on the list of super foods. The berry (Lycium barbarum) belongs to the Nightshade family and originates from Asia. In China, goji berries have been used for some four thousand years in medicine and food.
Goji berries are very vesatile: they can be used in infusions, medicines and dietary suplements, and it is eaten fresh. Dried Goji Berries can be eaten as they are, but are also delicious when added to bars, baked goods and muesli.
Our Low Pesticide Goji Berry is produced in accordance with the EU standards 0231010 : Tomatoes(goji berry is classified to tomatoes).
For the low pesticide goji berry, we control it in the planting process. A month or so before picking, it is forbidden for farmers to spray pesticides on the goji trees. In addition, we strictly prohibit farmers to use prohibited pesticides.
Of course, the types and quantities of pesticides need to be tested to confirm. We could offer organic certificate and test report, there are more than 200 items scanned by EUROFINS, Complies with EU standard.
