Common green manure crops? The use of green manure crops in orchards should be adapted to the local conditions according to climate, soil and fruit trees. Commonly used orchard green manure:? 1. Amorpha? Sowing in the spring, the amount of seed per acre is 1 to 2 kg, and it can also be spring strip. Harvesting 2 to 3 times a year for more than 2 years, 1000-2000 kg of fresh material can be harvested per mu. Amorpha fruticosa is adaptable, drought-tolerant, sorghum-resistant, salt-tolerant, hillside, alfalfa, and gully can be planted. After one year of planting, the branches and leaves are perishable and the fertilizer efficiency is high. ? 2. Mung beans? Sowing in spring and summer, the amount of seeds per mu is 2 kg. After 60 days of sowing, it will be harvested from full bloom to full bloom, and 1000-1500 kg of fresh material can be collected per mu. 1 sowing, harvested once in the same year, fast growth, high yield, perishable. Hi high temperature, drought tolerance, resistance to thinness, and impatience. Acidic soil or saline-alkaline soil can be planted. ? 3. Tian Jing? Sowing in spring and summer, using 3 to 4 kg per mu. Castration at the beginning of flowering, 1,500 kg of raw materials per mu. It is resistant to cockroaches, salt and alkali, and resistant to cockroaches. ? 4. Castor? Sowing in spring and summer, the amount of seeds per mu is 2 to 3 kg. It can be harvested 50 days after sowing, and can receive 2000-3000 kg of fresh material per mu. The castor is fast, and it can be castrated 2 or 3 times that year. ? 5. Scorpion? Sowing in autumn, the amount of seeds per mu is 2 to 3 kg. Harvesting in early summer, can harvest 2,000 to 2,500 kilograms of fresh material per acre. The scorpion plant is short, the branches and leaves are dense and tender, and it is perishable and has high fertilizer efficiency. The root system is developed and the effect of improving the sand is good. ? 6. Peas? Sowing in autumn, 7 to 10 kg per acre. Late spring, early summer, green, can harvest 1000-1500 kg of fresh material per acre. ? 7. What? It can be sown in spring, autumn and summer, harvested once in the same year, and harvested 3 to 4 times a year after the second year. ? Second, the use of orchard green manure? 1. Turn over? In the same year, a short green manure crop was planted between the fruit trees, and it could be directly plunged into the soil from the initial flowering stage to the flowering stage to make it rot. This method applies to mature orchards. ? 2. Indigo ditch buried? Digging trenches around the canopy, the width of the ditch and the depth of the ditch are both 30-40 cm. The ditch length is the same as the side of the canopy. The green manure and soil layer of the castration are buried in the ditch, and the water is filled once after covering the soil. This method is applicable to orchards with young or large spacing. ? 3. Cover the tree tray? Cover the tree tray with castrated fresh material or place it between the rows of trees for fertilizer. ? 4. How to control? The castrated fresh material is concentrated in the pit and then applied to the orchard. ? Third, pay attention to? 1. Apply a proper amount of nitrogen, phosphorus and potassium fertilizer in the green manure period to alleviate the contradiction between green manure crops and fruit trees. 2. Appropriate watering after pressing to accelerate the decomposition of green manure decay. 3. Try to use green manure crops that grow dwarf or semi-sorghum, and high-stalk green manure crops should be castrated in time. 4. Sowing perennial green manure crops, replanting for 4 to 5 years.
