Key points of field management of the latest water chestnut

Water chestnut is a kind of native plant in China, which is now distributed in most parts of the world. The planting area of water chestnut is mainly concentrated in the tropical provinces of China, which can not only be used as fruit, but also can be fried and eaten, but also has a certain effect, which can promote the peristalsis of intestines and stomach. So how should we manage when planting water chestnuts? The following editor brings you the key points of water chestnut field management, let's have a look!

1. Management at seedling stage

It is its seedling stage after the emergence of water chestnut seeds and before it is divided into plants. water chestnuts live in water. Therefore, it is necessary to keep the water level at about 4 cm in the seedling stage. Water chestnut enters the germination stage about half a month after planting. During this period, we should pay attention to observe the growth of seedlings. Weeds, yellow stalks and other substances that affect stem growth should be removed in time, which can be buried in the field to promote the growth of water chestnuts. Then apply nitrogen fertilizer once to control the amount of nitrogen fertilizer to prevent excessive amount of water chestnut from causing fertilizer damage.

2. Nutrition period management

When the water chestnut enters the tillering stage, we should focus on weeding, and try to do it together with topdressing every time. The main fertilizer is also nitrogen fertilizer, and attention should be paid to raising the water level during the peak period of corm growth. Raise the water level to about 7-8 cm, and during the nutrition period, the harm of water chestnut diseases and insect pests is more serious. For example, dry blight, stem borer and so on, so we also need to make corresponding control measures according to diseases and insect pests to enhance the growth capacity of water chestnut, increase yield and protect their own planting benefits.

3. Field management

After water chestnut transplanting, the soil temperature should be raised properly to promote the green tillering of water chestnut seedlings and watering properly. Then, with the growth of seedlings, the water consumption in the field will gradually increase, so we should raise the water level appropriately according to the actual situation. Promote the growth of aboveground parts. Then, after closing the line, it is necessary to control the application of nitrogen fertilizer, if there is too much nitrogen fertilizer, it is very easy to lead to the excessive growth of water chestnut seedlings. During the period from sowing to harvesting of water chestnuts, the phenomenon of water shortage cannot occur, especially in the expansion period, if there is a shortage of water, it will have a great impact on the yield.

4. Pest control

The phenomenon of diseases and insect pests of water chestnut is very serious, so the prevention and control of diseases and insect pests is also a good management work. The common diseases and insect pests of water chestnut are Fusarium wilt, Sclerotinia sclerotiorum and locusts. Therefore, we strengthen management, reasonable watering and fertilization, while meeting the water and fertilizer needs of water chestnuts. It is also necessary to avoid waterlogging and fertilizer damage and improve the incidence of diseases and insect pests. We need to understand the symptoms of each kind of diseases and insect pests, so that the specific diseases and insect pests can be identified in time to carry out corresponding control measures.

The above is a brief introduction to the main points of water chestnut field management. The management of water chestnut is very important, so we must pay attention to it when planting to protect our own planting benefits. That's all for today's introduction.
