New technology of accurate management of alfalfa

Soil preparation, before planting, clean the ground, pull grass, loosen the soil, and rake the soil into fine particles, so as to provide a suitable soil environment for alfalfa sowing, emergence, growth and development.

Sowing, the seeds should be cleaned, removed impurities, and then mixed with new high-fat membrane, which can keep heat, moisturize, absorb swelling, improve the seed germination rate and make the seedlings strong.

Fertilization, in the process of planting, alfalfa should absorb a lot of nitrogen, calcium and potassium. Alfalfa Rhizobium can fix free nitrogen in the air and has a strong ability of nitrogen fixation. Therefore, nitrogen fertilizer is generally not applied during the growth and development of alfalfa. The growth of alfalfa requires a large amount of potassium. The content of calcium is generally applied before or during sowing.

Field management, raking the land to kill weeds when it is green in early spring, and ploughing and weeding after each cutting. Herbicides can be used to remove old alfalfa fields. Irrigation should be timely in the dry season, and drainage should be paid attention to in the hot and rainy season in summer to prevent rotting roots caused by too much water. During the growing period, vegetable Zhuangcauling can be sprayed to make the seedlings grow luxuriantly, with thick leaves, high yield and high quality.
