Daily management methods and matters needing attention of alfalfa

Alfalfa, commonly known as Jinhua Cai, is a perennial flowering plant with a wide variety of species. It was originally used in livestock feed, but due to the high nutritional content of alfalfa, human consumption is also very beneficial to health. Its medicinal value is also very high, with the effect of clearing spleen and stomach, diuretic and detumescence. The growth ability of alfalfa is very strong, so many growers grow alfalfa. So how should alfalfa be managed? Next, let's popularize the main aspects of planting prospects.

1. Timely watering

Alfalfa consumes a lot of water and has a high demand for water, so water management should be done well during alfalfa planting to keep the soil moist and suitable, but if there is a lot of rainfall, the number of watering can be reduced appropriately. There is also a need to pay attention to drainage, can not let the soil field too waterlogged, this will lead to alfalfa roots rot, growth speed and quality will be affected. Therefore, during the planting period, we should pay more attention to the situation of the soil field and water and drain in time.

II. Timely topdressing

Alfalfa growth ability is very strong, there is no requirement for the growth environment, but if sufficient nutrients are added, the growth speed of alfalfa can be further improved, thus increasing the yield of alfalfa. During the planting period, more attention should be paid to the use of base fertilizer and topdressing. Fertilizer should not be applied blindly. Base fertilizer is generally applied with diammonium phosphate and urea. Later topdressing is mainly urea and phosphate fertilizer. Appropriate topdressing can increase the quality and yield of alfalfa.

III. Cultivation and weeding

Weed removal is also essential during alfalfa planting. Seedling and summer are weak periods for alfalfa growth and are susceptible to weed overgrowth. Weeding must be strengthened during these two periods. Intertillage can strengthen soil quality, improve soil permeability, and create a good environment for alfalfa to absorb nutrients. Therefore, intertillage and weeding are beneficial to alfalfa growth, which can be paid attention to during management.

IV. Pest control

The control of alfalfa diseases and insect pests is a point that needs to be paid attention to very much. If it is not controlled in time, it will have a serious impact on yield and quality. Common diseases and insect pests of alfalfa include downy mildew, aphid, leaf spot, etc., which can be prevented and controlled by carbendazim, topril, dimethoate and other insecticides. Prevention work should be done well in advance, and pest control should be strengthened during planting management.

V. Inspection and supplement of seedlings

During alfalfa planting and management, observe the growth of alfalfa. When weed is clear, pay attention to whether the seedling grows normally. If there are weaker seedlings, remove the seedlings and give sufficient nutrients to the strong seedlings. If there are seedling gaps found in the field, plant healthy seedlings in time. Inspection and supplement of seedlings is also an aspect that needs attention during management. Only by paying attention to management can quality and yield be enhanced.
