Planting technology of water chestnuts
1. Select appropriate varieties
Choosing excellent varieties is the basis for high yield, and it is also the key to competing for the season, occupying the market early, and improving economic benefits. key. If raw food is the main food, early and medium-ripening varieties with large water chestnuts (two-cornered water chestnuts) can be selected and put on the market in batches. Mainly for high yield, the Wuling variety with late maturity period can be planted. At the same time, because water chestnut species are prone to degradation, care must be taken to select water chestnut seeds with full rhombus shapes, high solidity, fully hardened peel, and no pests or diseases.
2. Plant at the right time and plant reasonably densely
The appropriate time for local water chestnut planting is generally before and after the Qingming Festival, when the water temperature is stable above 12°C. The methods can be divided into direct seeding and seedling transplantation. Plant two kinds. Before sowing, pay attention to clearing aquatic plants, moss and wild water chestnuts in the river pond. The seed amount per mu is generally 10kg. For river ponds with poor fertility, the seed amount can be increased appropriately. For river ponds with large water surfaces and deep water, seedling transplanting can be used. The seedlings are about 60 days old, have 10 top leaves, have a rhombus disk of 15cm, and have 2 to 3 branches. When stocking, tie 10 plants into a bunch with a straw rope and gradually insert them into the bottom of the water. If the density of water chestnuts is too high after the water chestnuts grow out of the water, artificial thinning and even seedlings can be used to prevent the water chestnuts from sealing the water surface early and causing a small opening, which affects the yield.
3. Strengthen water chestnut management
(1) Apply sufficient base fertilizer. Water chestnut is an aquatic plant, so its fertilizer requirement is different from that of xerophytic crops, and the amount of fertilizer required is relatively concentrated.
Before planting, 2,000kg of pig manure or decomposed mud manure can be applied per mu. When the water chestnuts sprout, 5kg of urea can be applied per mu as a quick-acting fertilizer. After flowering, it can be divided into 2 to 3 times in combination with 2 to 3 packets of powerful yield-increasing fertilizer for disease and insect control or 2% Potassium dihydrogen phosphate is sprayed on the leaves to prevent premature aging.
(2) Pest control and weeding. Common insect pests of water chestnuts include aphids, leafhoppers, etc. In the early stage of the damage, 90% crystal trichlorfon 800 times solution or 5-6 bottles of trichlorfon mixed with 50kg of water can be sprayed with a small machine. Spray once every 10 days. The use of highly toxic pesticides such as methamidophos is strictly prohibited to reduce the risk of damage. Residual poison prevents water chestnut deformity or empty shells. In ponds where water chestnuts are stocked, there are many types of aquatic weeds, including deep-water ichthyosaurs, shallow-water green duckweed, plankton grass, centipede grass, moss grass, etc. They must be removed manually in time, otherwise the photosynthesis of water chestnuts will be affected. Generally, after the water chestnuts are put in, weeds should be removed every 10 days until the water chestnuts cover the water surface.
4. Timely picking
Water chestnuts begin to mature 20-30 days after flowering. The maturity period of early-maturing varieties is from August 15th to 20th, and the maturity period of late-maturing varieties is in late September and early October. If cooked or eaten raw, it is best to harvest when the sepals fall off and the peel is not fully hardened. If they are to be eaten cooked, processed or kept as seeds, they must be picked when fully mature. Early-maturing varieties are picked every 5 days, late-maturing varieties are picked every 7 days, and the entire harvest period is divided into 6 to 7 times. When harvesting, be careful to lift the water chestnut plates and pick the water chestnuts gently, and lay them flat after harvesting to avoid damage. If you want to save water chestnuts for seed, wash them in water in time after harvesting to remove the floating tender water chestnuts. In the future, change the water every 10-15 days to ensure the germination rate of water chestnuts in the coming year.
