How to plant water chestnut

The protein content of water chestnut is extremely high. It is an aquatic herb, mainly from the Yangtze River and the Pearl River. Its efficacy and scope of use are relatively wide. It is most commonly used for clearing heat and diuresis, as well as some diseases such as intestinal and gastric cancer, uterine cancer, breast cancer, hemorrhoids and so on. It can be used as a vegetable and eaten raw as a fruit, so how to grow water chestnut? Next, let's learn about it together.

1. Select improved varieties

At present, there are still many varieties of water chestnut on the market, so to choose varieties with high quality, high yield, strong resistance and good market quotation for seeds, then we need to investigate the local climate, soil, market and so on. Then select the varieties of water chestnut which are suitable for local planting, which can not only improve the yield and quality of water chestnut, but also improve the economic benefits of water chestnut planting.

2. Soil selection

Water chestnut is a kind of aquatic plant, so when choosing the planting site, it should be close to the water source area as far as possible, at the same time, it is a kind of light-loving plant, so it is best to choose a sunny place, it is best to have more organic matter in the soil, and nutrient-rich ponds or lakes are conducive to drainage and irrigation, and the depth of silt in the water is not less than 20 centimeters. When preparing the soil, clean up the excess silt in the pond, clean up the weeds in the pond, sprinkle an appropriate amount of farm manure and then disinfect it, and then sow seeds after disinfection.

3. Sowing seeds at the right time

If you want to have a high yield of water chestnut, you need to plant it at the right time. As there are several ways of planting water chestnut, we need to determine the planting time according to the specific planting pattern. Secondly, we also need to consider the climate and temperature of the planting site. The normal planting time of water chestnut is usually around the beginning of March every year, but if the greenhouse technology is used for planting. It can be planted in December every year.

4. Reasonable close planting

At present, the most commonly used breeding method of water chestnut is to propagate separately, that is, to choose the rhizome of water chestnut, which has a relatively strong rhizome, and to plant it according to a distance of about one meter to two meters per row and about one meter per plant when planting. Because its branching ability is very strong, it will soon grow dense. About a week after planting, it is necessary to check the growth of water chestnut in the field. If you send a letter that there is a lack of seedlings, you need to replenish the seedlings in time to ensure the quality of the seedlings in the field.

5. Field management

In fact, the most important thing in field management is the regulation of water level and the management of water quality, followed by fertilization and weeding. After the water chestnut is planted, it is best to control the water level in the field at about 25 cm, and then slowly increase the water level with the growth of water chestnut. However, the maximum water depth in the field can not exceed two meters, and secondly, we also need to change water at ordinary times. Otherwise, it will cause a lot of unnecessary diseases. Then, when the water chestnut is rooting, the most appropriate amount according to its growth is urea or fecal water, and when the water chestnut blossoms and bears fruit, it is best to get rid of the weeds before it grows, otherwise it will be difficult to weed after the water chestnut grows.

6. Pest control

The most common diseases and insect pests in water chestnut are white silk disease and firefly. There are many white silk disease caused by white silk disease, such as too many weeds, partial application of nitrogen fertilizer, low or deep water level, etc., so we can use carbendazim for control, at the same time appropriate amount of nitrogen fertilizer, and timely weeding and scientific control of water level. On the other hand, the firefly mainly harms the water chestnut of water chestnut, which affects the amount of water chestnut, so dimethoate milk can be used to control it.
