Cyclamen pot technology

Cyclamen is a radish jellyfish, rabbit ear flower, and a canopy. It is a perennial bulbous flower of Cymbidium. Because of its variety, its bulb size varies greatly and its color is also different. The color of the leaves varies endlessly. The calyx is mostly green, white, pink and red-brown. It blooms in winter and lasts for several months. It is one of the world's most famous potted ornamental flowers. Lianjiang County introduced and promoted it from Japan in 1987. Since 1995, it has been prevailing throughout the county. Since 2000, it has gradually developed into a small-scale business with professional households. The level of cultivation management and economic efficiency have increased year by year. According to statistics, there are only 13 specialized households with planting scale of over 200 basins in the county and more than 10,000 yuan in annual profits. There are more sporadic growers. Now we introduce its potted technology as follows:
1 Biological characteristics Cyclamen can be divided into five stages: seed germination stage, flowering stage, seedling stage, flower bud differentiation stage, accelerated growth stage and flowering stage. Suitable growth temperature is 10 to 20°C. There are no special requirements for the photoperiod, and lighting can be supplemented with light in the home pot.
2 Cultivation and Management Technology
2 1 Preparation of nutritious soil The pond may be dug in the past years, or the loess on the ground may be excavated from the mountain, weathered in the outdoor shade, and then mixed with about 1% of cooked rapeseed meal or manure, and Pot soil dressing 10 imported ternary fertilizer, to be used when the basin.
2 2 Selection of Flower Pots The height of cyclamen flower pots is generally 2/3 or more higher than the plant height. Large flower varieties use 15 ~ 18cm diameter flowerpots, pot height 20 ~ 30cm; medium and small flowers with 12 ~ 14cm diameter pots, pots about 16cm high.
2 3 The upper basin and the basin are generally sown in September and December. After the nursery stage, the young plants grow to 6-8 leaves in the second year from March to April. When planting, the bulbs must be exposed to 1/3 to 1/2 of the topsoil, fully watered, and shaved for 2 to 3 days before normal management. After 2 weeks in the upper bowl, liquid fertilizer was applied twice a month. The N, P, and K were 65%, 60%, and 19% of 2000 times, respectively, and some of the cooked thin farmyard fertilizer was also available. Seedlings in particular need to increase the supply of potassium to enhance resistance to disease. To 5 ~ June can be a change basin, if you want to cultivate large plants, it will be carried out in August to September, the basin of the model is larger than the original basin. The operation of changing the basin is basically the same as that of the upper basin.
2 4 Fertilizer Management Organic fertilizer is generally used as a base fertilizer by blending in a nutrient soil after retanning. The inorganic fertilizer is formulated into liquid fertilizer for top dressing. The principle of formulating liquid fertilizer is to produce no precipitation, and firstly prepare 200 times of mother liquor reserve and use it, and when it is watered, mix it into 0-2% to 0 3% working solution. The PH value of liquid fertilizer is required to be 52 to 45, the ratio of N, P, and K is 1:1:1 before mid-August, and 2:1 to 2:1 after mid-August. In early October, 1:1 is required. :1. It is best to use stored rainwater to water in the morning and master the principle of “do not do it, don't pour it, pour it out”.
2 5 Plasticity is mainly the removal of the yellow leaves and the weakness of the thin leaves in the early stage, and the central leaves are pulled outwards in the later stages, and the flowers and sick leaves that were opened in the flowering stage are removed. When picking flowers, use the thumb and index finger to pinch the middle and lower part of the pedicel, and turn it to the left and right to make the base of the pedicel soften and loosen from the plant.
2 6 Major diseases and pests and their main diseases are wilt disease and bacterial soft rot. The key to combating wilt disease is to water well and use 2000 times benomyl or mancozebite to irrigate the roots; bacterial soft rot often occurs in the high temperature and humidity period in summer, spraying or smearing 4000 times streptomycin or new in the early stage of disease. Phytonomycin, and drenched nutrient soil. Insect pests mainly include ticks, aphids, and ticks. Anthraquinones occur in the autumn of high temperature and drought, and can be sprayed with 40% dicofol from 1000 to 1500 times; 80% of diphtheria emulsion can be used to control aphids 1000 times, 20% of bleaching emulsion can be 1000 times, and 10% can be used as a wettable powder. 3000 times liquid spray to kill; prevention and control of earthworms should seize their habits of day and night out, in the young age with 20% Guangsha Ling 1000 times solution or 20% killer emulsion EC 1000 times spray, combined with manual killing, Better results.

Fluorine-Containing Methylbenzene products can be used as herbicides in the manufacture controlling wheat fields, cotton fields and other broadleaf weeds and perennial weeds. It can also be used in the manufacture of antipsychotics drugs.
The Fluorine-Containing Methylbenzene products must be kept under seal, once exposed to light will immediately cause discoloration. It should also be stored in a cool, ventilated warehouse, away from fire and heat. Compartment temperature should not exceed 30 ℃. And make the appropriate technical measures for fire and explosion. Products will Decomposition by high fever and emit toxic gases, such as carbon monoxide, carbon dioxide, hydrogen fluorid. Due to ts vapor is heavier than air, it can spread from low place to far away places. In case of fire conditions, should not fire with water. In case of a small amount of leakage should be evenly sprayed with dilute hydrochloric acid. In case of large spills should build a causeway or trenching asylum. The transfer pump to tankers or exclusive collector, recycling or shipped to the waste disposal sites.
