Fertilization technology of water chestnut

Water chestnut, also known as horseshoe chestnut, black taro, etc., is a perennial root herb, which can be eaten raw or eaten as a vegetable. it is originated in China and is now widely planted all over the world. But if you want to grow water chestnuts well, fertilization is very important. Let's take a look at the fertilization techniques of water chestnuts together with Xiaobian.

1. Apply sufficient base fertilizer

Some farmers apply light base fertilizer or no base fertilizer when planting, which will lead to slow emergence and weak growth of water chestnut, resulting in weak plants and low yield. Therefore, base fertilizer must be fully applied. Generally, more than 1000 kilograms of rotten farm manure per mu should be used as base fertilizer, while nitrogen, phosphorus and potassium fertilizer should be properly supplemented. Conditional application of 1-2 kilograms of borax and 1 kilogram of zinc sulfate per mu can increase trace elements in the soil and promote plant growth.

2. Topdressing in time

In order to promote the growth of aboveground stems and leaves in the early growth stage, nitrogen fertilizer must be applied in the early stage, while potassium fertilizer should be used to promote corm expansion and increase yield in the later stage. After transplanting survived, it is necessary to combine with weeding and fertilization in the middle tillage. Generally, 6-8 kg of urea per mu can promote plant tillering. In the plant division, it is also necessary to combine with inter-tillage weeding and fertilization once, apply 20 kg potassium sulfate compound fertilizer per mu, fertilize once after transplanting for one month, and apply 50 kg potassium sulfate compound fertilizer in combination with middle ploughing and weeding. This is the number of times for the growth of water chestnut.

3. Re-apply Capsella manure

It is necessary to re-apply shepherd's shepherd fertilizer from September to October to provide sufficient nutrients to the fruit. Generally, 40 kg of potassium sulfate compound fertilizer and 15-20 kg of potassium sulfate are applied per mu. Fertilization must be carried out after the dew is dry, and the surface fertilizer is stained on the leaves and absorbed by the stems and leaves after dissolving in dew, resulting in the overgrowth of the plant. it can also be carried out in the evening or cloudy days.
