The main cultivation techniques of alfalfa

In summer production, we should choose soil with loose soil and deep fertile soil, and be in a cool and convenient place for irrigation and drainage. Each farmhouse rots 1,000 kg to 2,000 kg of farmyard manure, and mixes well with the soil and presses 1.7 meters to open the ridges and make rakes. Turtle back surface to prevent accumulation of water. (b) Seeds soaked in germination pods are fruits, seed coats are harder, and seeds must be sown before sowing. The peel can be peeled off with a stick first, 2 seeds are separated, then soaked for 12 hours, wrapped in a wet cloth, and left at about 20°C to destroy the bud. Seeds begin to bloom after 5 days to 7 days. (3) Sowing seedlings can be sowed or drilled. Drilling is easy to manage. The general spacing l0 cm, open shallow ditch, dense sowing, the amount of 8 kg per kg -10 kg. After sowing, cover the thin soil, cover with a thin layer of grass, and apply enough water. In the plain area where the sun shines, use a black gauze net or grass shed to cover it. The height of the shed should be about 1 meter. (D) Fertilizer Management After emergence, we must ensure that the water supply is even. Fertilizers should be based on quick-acting fertilizers. After each application of leaching, rinse with water again, avoid high concentrations of leaching, so as not to hurt the seedlings. In the early stage, apply 2 kg to 3 kg of compound fertilizer per acre for 2-3 times. When the plant grows to 10 cm in height, apply 5 kg-l0 kg of compound fertilizer per acre, once every 7 days to 10 days. (5) Harvesting shall be carried out in batches according to market demand. General sowing and harvesting shall be 50 days to 70 days. When harvesting, you can pull up and remove the sludge. Be careful not to rinse with water.
