How to carry out field management of Chinese water chestnut? A detailed explanation of the latest key points
The Chinese water chestnut is a plant native to China and is now distributed across most regions of the world. Its cultivation area is mainly concentrated in the tropical provinces of China. It can be eaten not only as a fruit but also stir-fried, and it also has certain medicinal effects, as it can promote gastrointestinal peristalsis. So how should we manage it when growing Chinese water chestnuts? Below, the editor brings you the key points of field management for Chinese water chestnut. Let's take a look!
1. Management during the seedling stage
The seedling stage of the Chinese water chestnut runs from after the seeds emerge until before they begin to tiller. The Chinese 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, the Chinese water chestnut enters the tillering stage. During this period, pay attention to observing the growth of the seedlings. Promptly remove weeds and yellow stems and other material that affects the growth of the stems; these can be buried in the field to promote the growth of the Chinese water chestnut. Then apply a topdressing of nitrogen fertilizer once, controlling the amount well to prevent excessive application from causing fertilizer damage to the Chinese water chestnut.
2. Management during the vegetative stage
⟦NL>When the Chinese water chestnut enters the tillering stage, focus on doing a good job of weed control, and try to carry out each weeding together with topdressing. The main fertilizer is also nitrogen-based. During the peak growth period of the corms, pay attention to raising the water level. Raise the water level to about 7-8 cm, and during the vegetative stage, the pest and disease damage to Chinese water chestnuts is relatively severe. For example, dry rot and stem borers, so we should also carry out corresponding control measures according to the pests and diseases, enhance the growth capacity of the Chinese water chestnut, increase yield, and protect our own cultivation benefits.
3. Field management
After the Chinese water chestnut is transplanted and planted, the soil temperature should be appropriately raised to promote the revival and tillering of the Chinese water chestnut seedlings, and water should be applied appropriately. Then, as the seedlings grow, the field's water consumption will gradually increase, so we should appropriately raise the water level according to actual conditions. Promote the growth of the aboveground part. Then, after the rows close, control the application of nitrogen fertilizer; if there is too much nitrogen fertilizer, it can very easily cause excessive vegetative growth of the Chinese water chestnut seedlings. From sowing to harvest of the Chinese 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. Pest and disease control
The damage caused by pests and diseases to Chinese water chestnuts is very severe, so pest and disease control is also a management task we must focus on doing well. Common pests and diseases of Chinese water chestnuts include fusarium wilt, sclerotinia rot, and locusts. Therefore, we should strengthen management, water and fertilize reasonably, and while meeting the water and fertilizer needs of the Chinese water chestnut, we should also avoid waterlogging damage and fertilizer damage, and reduce the incidence of pests and diseases. We should understand the symptoms of each pest and disease so that after onset we can promptly identify the specific pest or disease and carry out corresponding control measures.
The above is a brief introduction to the key points of field management for Chinese water chestnut. The management work for Chinese water chestnut is very important, so we must pay attention to it when planting to protect our own cultivation benefits. That is all for today's introduction.
