How and when to plant alfalfa?

Alfalfa can be planted in spring, summer and autumn, and the planting effect is the best in spring and autumn.

1, seed selection.

Choose seeds before planting, and be sure to choose alfalfa seeds with good quality. Generally speaking, alfalfa seeds such as Liangmu No.5, Saite, Debao and Suntory are used.

2. Preparation for planting.

Properly treat seeds and soil before sowing. The treatment methods of open field seeds mainly include pesticides, sterilization, inoculation of rhizobia and so on. Soil treatment mainly includes ploughing, fertilization, weeding and pesticides.

3. Seed treatment.

The place where alfalfa is planted for the first time should be mixed with rhizobia. 5 grams of rhizobia agent per catty of seeds, and sow immediately after mixing.

4. Fertilize.

Alfalfa has nodules, which can fix nitrogen in the air and provide nitrogen for itself. Therefore, phosphorus is the main application, and potassium is applied appropriately. In barren land, saline-alkali land and places with low nitrogen content in soil, a certain amount of Bika water-soluble fertilizer is applied as sowing fertilizer.

5. Water resources management.

Alfalfa roots are deeply planted in the soil and have strong drought resistance. Timely watering in dry season and watering after mowing can obviously increase the yield. Pay attention to eliminate stagnant water in time in rainy season.

6. weeding.

From sowing to seedling stage, after turning green every year, we should pay attention to weeding every harvest. Manual uprooting and chemical weeding can be carried out. Chemical weeding can spray a special herbicide for clover.
