Planting method and time of water chestnut: how to plant water chestnut? 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.

Planting method:

For the planting of water chestnuts, generally speaking, they are still used to planting early (the specific time range is in spring). It is probably possible to bear water chestnuts in autumn, and then wait for the seeds to be harvested and selected for next year's seedling treatment.

Water chestnut for fertilizer and water requirements are not very high, generally speaking, before planting need to apply a basic fertilizer, pay attention to mix with the surface culture soil, pay attention to the concentration is not too high, can ensure the early fertilizer supply on it. Then is the water chestnut in the growing period of fertilizer and water treatment, generally stuck in the ploughing and weeding stage fertilization two or three times, followed by a compound fertilizer can be added.

Water chestnut watering should be moderate, generally speaking, it can basically ensure the wetness of the surface culture soil, and the surface moisture height should not exceed two to three centimeters as far as possible. If in the growth period of water chestnut, then the water depth should be guaranteed at about 8 cm, which can effectively ensure the normal growth of water chestnut.

When planting young water chestnut plants, we should pay attention to the planting time and planting density, generally try to plant in the early stage of transplanting period, pay attention to planting density can be a little smaller. The hole depth of planting seedlings is generally about five or six centimeters, not too deep or too shallow.

Relatively speaking, water chestnut diseases and insect pests are not very serious, mainly manifested as the common stem blight, which often occurs in late summer and early autumn every year. For prevention, the first thing is to select disease-resistant varieties when selecting seeds, then soak the seeds when sowing, and then if diseases occur during the growth period, it is necessary to immediately carry out relevant insecticide dilution spraying (there are special pesticides on the market). Of course, pay attention to burning stalks every year after harvest to reduce egg residue.

For the collection and harvest of water chestnuts in the mature period, we generally have to wait until the branches and leaves of the water chestnuts on the ground die, because the water chestnuts we want are the bulbs in the underground part, which is already ripe at this time. Of course, you can also choose not to harvest now and wait until next spring to harvest and go public.

Fertilization technology:

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.
