What are the key points of field management for water chestnut? Read this article to understand
Water chestnut is a plant native to China, and it is now distributed in most parts of the world. The planting area of water chestnut is mainly concentrated in the tropical provinces of China. It can not only be eaten as a fruit, but can also be stir-fried for consumption, and it also has certain medicinal effects, as it can promote gastrointestinal peristalsis. So how should we manage water chestnut when planting it? Below, the editor brings you the key points of field management for water chestnut. Let's take a look!
1. Management during the seedling stage
After the water chestnut seeds germinate and before they tiller, this is its seedling stage. Water chestnut grows in water. Therefore, during its seedling stage, the water level should be kept at about 4 cm. About half a month after planting, water chestnut enters the tillering and growing stage. During this period, pay attention to observing the growth of the seedlings. Weeds and yellow stems and other substances affecting stem growth should be removed in time, and they can be buried in the field to promote the growth of the planted water chestnut. Then apply a topdressing of nitrogen fertilizer once, and control the amount well to prevent excessive application from causing fertilizer damage to water chestnut.
2. Management during the nutritional stage
When water chestnut enters the tillering stage, we should focus on doing a good job of weed control, and each time we weed, we should try to carry it out together with topdressing. The main fertilizer is also mainly nitrogen fertilizer. During the vigorous growth period of the corms, attention should be paid to raising the water level. Raise the water level to about 7-8 cm, and during the nutritional stage, the damage caused by diseases and insect pests to water chestnut is relatively serious. For example, dry rot, stem borers, etc., so we should also carry out corresponding prevention and control measures according to the diseases and insect pests, enhance the growth ability of water chestnut, increase yield, and protect our own planting benefits.
3. Field management
After water chestnut is transplanted and planted, the soil temperature should be appropriately raised to promote the revival and tillering of water chestnut seedlings, and watering should be done appropriately. Then, as the seedlings grow, the water consumption in the field will gradually increase, so we should appropriately raise the water level according to the actual situation. Promote the growth of the aboveground part. Then after the rows close, the application of nitrogen fertilizer should be controlled. If there is too much nitrogen fertilizer, it is very easy to cause excessive vegetative growth of water chestnut seedlings. From sowing to harvesting of water chestnut, there must be no water shortage, especially during the enlargement period. If there is a water shortage, it will have a great impact on yield.
4. Disease and pest control
The damage caused by diseases and insect pests to water chestnut is very serious, so disease and pest control is also a management task we must focus on doing well. Common diseases and insect pests of water chestnut include fusarium wilt, sclerotinia disease, and locusts, etc. Therefore, we should strengthen management, water and fertilize reasonably, and while meeting the water and fertilizer needs of water chestnut, we should also avoid waterlogging and fertilizer damage, and reduce the incidence of diseases and insect pests. We should understand the symptoms of each disease and insect pest so that after onset we can promptly identify the specific disease or pest and carry out corresponding control measures.
The above is a brief introduction to the key points of field management for water chestnut. The management work for water chestnut is very important, so we must pay attention to it when planting to protect our own planting benefits. That is all for today's introduction.
