Planting techniques of water chestnut
1, select the appropriate variety.
Selecting excellent varieties is the basis of high yield, and it is also the key to win the season, occupy the market early and improve economic benefits. If raw food is the main food, you can choose the early and middle-maturing variety (water chestnut) with large water chestnut and put it on the market in stages and batches. Wuling varieties with high yield and late maturity can be planted. At the same time, due to the easy degradation of water chestnut varieties, we must pay attention to the selection of water chestnut seeds with full diamond shape, high fullness, completely hardened peel and no pests and diseases.
2, timely sowing, reasonable close planting
The suitable time for local water chestnut stocking is generally that the water temperature is stable above 12℃ before and after Qingming Festival, and the methods can be divided into direct seeding and seedling transplanting. Before sowing, attention should be paid to the removal of aquatic plants, moss, wild water chestnut and so on in the river pond. The amount of seeds used per mu is generally 10kg, and the amount of seeds used can be appropriately increased in the ponds with poor fertility. In ponds with large water surface and deep water depth, seedlings can be transplanted. The seedling age is about 60 days, and the top leaf 10. When the rhombus 15cm has 2 ~ 3 branches, tie it into a bundle with 10 straw rope and gradually insert it into the bottom of the water. If the density of water chestnuts is too high after growing, artificial thinning and even seedling raising can be adopted to prevent the water chestnuts from being sealed prematurely and the opening is small, which will affect the yield.
3. Strengthen the management of Tang Ling.
(1) Apply sufficient base fertilizer. Water chestnut, as an aquatic plant, has a different demand for fertilizer from dry crops, and the demand for fertilizer is relatively concentrated. Before planting, 2000 kilograms of pig manure or decomposed mud fertilizer can be applied per mu. When water chestnut germinates, 5 kilograms of urea can be applied per mu as a quick-acting fertilizer. After flowering, you can cooperate with 2 ~ 3 packs of powerful yield-increasing agents to prevent diseases and insects or spray 2% potassium dihydrogen phosphate on the leaves to prevent premature aging.
(2) Pest control and weeding. The common pests of water chestnut are aphids, leafhoppers and so on. At the initial stage of damage, 90% crystal trichlorfon 800 times solution or 5-6 diphacinone mixed with 50 kg water can be sprayed once every 10 day. It is strictly forbidden to use highly toxic pesticides such as methamidophos to reduce residual toxicity and prevent water chestnut from deformation or cavitation. There are many kinds of aquatic weeds in the pond where water chestnut is stocked, such as deep-water lotus grass, shallow-water duckweed, flat grass, Pteris vittata grass, bryophyte grass, etc., which must be removed manually in time, otherwise the photosynthesis of water chestnut will be affected. Generally, after water chestnut is put into use, weeds should be removed every 10 day until water chestnut is completely covered.
Step 4 choose in time
Water chestnut begins to mature 20-30 days after flowering. The maturity of early-maturing varieties is from August 15 to 20, and that of late-maturing varieties is from the end of September to the beginning of October. If cooked or eaten raw, it is best to harvest when the sepals fall off and the peel is not completely hardened. If cooked, processed or stored, it must be picked at full maturity. Early-maturing varieties are picked once every 5 days, and late-maturing varieties are picked once every 7 days. The whole harvest period is divided into 6 ~ 7 times. When harvesting, pay attention to gently lift the water chestnut plate, pick the water chestnut, and lay it flat after harvesting to avoid damage. If water chestnut is to be planted, it should be washed with clear water in time after harvest to remove floating tender water chestnut, and then fresh water should be replaced every 10- 15 days to ensure the germination rate of water chestnut in the next year.
