Introduction to the main points of field management of horseshoe (water chestnut)!

Water chestnut planting area is mainly concentrated in China's tropical provinces, not only can be used as fruit, but also can be fried food, and there is a certain effect, can promote gastrointestinal motility, the following to introduce water chestnut (water chestnut) field management points introduction!

1. Management of seedling stage

Water chestnut seeds are in the seedling stage after emergence to before plant division. Water chestnut lives in water, so the water level should be kept at about 4cm during the seedling stage. Water chestnut enters the seedling stage about half a month after planting. During this period, attention should be paid to the growth of seedlings. Weeds and yellow stems that affect stem growth should be uprooted in time. They can be buried in the field to promote the growth of water chestnut seeds. Nitrogen fertilizer should be applied once. The dosage should be controlled. Prevent excessive dosage from causing fertilizer damage to water chestnut.

II. Management of vegetative period

When water chestnut enters tillering stage, we should focus on weeding work, try to carry out together with topdressing work every time weeding, the main fertilizer is mainly nitrogen fertilizer, pay attention to raising the water level when the bulb grows vigorously, raise the water level to about 7-8cm, in the vegetative stage, the pest damage phenomenon of water chestnut is more serious, such as dry disease, stem borer, etc., but also according to the pest corresponding prevention and control measures, enhance the growth ability of water chestnut, improve yield.

III. Field management

After transplanting and planting of water chestnut, the soil temperature should be appropriately raised to promote the regeneration and tillering of water chestnut seedlings. Water should be properly watered. With the growth of seedlings, the water consumption in the field will gradually increase. The water level should be appropriately raised according to the actual situation to promote the growth of aboveground parts. After sealing the rows, the application of nitrogen fertilizer should be controlled. If there is too much nitrogen fertilizer, it is easy to cause excessive growth of water chestnut seedlings. During the period from sowing to harvesting of water chestnut, water shortage phenomenon cannot occur. Especially in the expansion period, if water shortage, it will have a great impact on yield.

IV. Pest control

The pest damage phenomenon of water chestnut is very serious, so the pest control should also pay attention to good management. The common pests and diseases of water chestnut include blight, sclerotia and locusts. It is necessary to strengthen management, water and fertilize reasonably. While meeting the water and fertilizer requirements of water chestnut, it is also necessary to avoid waterlogging and fertilizer damage, improve the incidence of pests and diseases, understand the symptoms of each pest and disease, so as to find out the specific pests and diseases in time after the disease occurs. Corresponding prevention and control measures.

The above is a simple introduction to the field management points of water chestnut, the management of water chestnut is very important, must pay attention to in the planting process, in order to ensure the planting benefit.
