First, commonly used 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 manures are:
1. Amorpha. Sowing in the spring, the amount of seed is 1-2 kg per 667 square meters, and it can also be spring strip. More than 2 years of harvesting 2 to 3 times a year, each 667 square meters can harvest fresh materials 1000-2000 kg. 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 seed is 2 kg per 667 square meters. After 60 days of sowing, it will be harvested from full bloom to full bloom, and it can collect 1000-1500 kilograms of fresh material per 667 square meters. Harvested in the same year, rapid growth, high yield, perishable; like high temperature, drought tolerance, resistance to thin, not resistant to sputum; acid soil or saline-alkaline soil can be planted.
3. Tian Jing. Sowing in spring and summer, 3 to 4 kg per 667 square meters. At the beginning of flowering, the harvest is 1,500 kg per 667 square meters. It is resistant to cockroaches, salt and alkali, and resistant to cockroaches.
4, castor. Sowing in spring and summer, the amount of seeds used per 667 square meters is 2 to 3 kg. It can be harvested 50 days after sowing, and it can collect 2,000-3,000 kilograms of fresh material per 667 square meters. Castor grows rapidly and can be harvested 2 or 3 times that year.
5, scorpion. Sowing in autumn, the amount of seed is 2 to 3 kg per 667 square meters. Harvested in early summer, 2,000 to 2,500 kilograms of fresh material can be harvested per 667 square meters. 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 in autumn, planting 7 to 10 kg per 667 square meters. Late spring, early summer, green, every 667 square meters can harvest fresh materials 1000-1500 kg.
7, hehe. 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, cut green. The trench is buried in the outer periphery of the canopy. The width of the trench and the depth of the trench are both 30-40 cm. The length of the trench is the same as that on the side of the canopy. The green manure and the soil layer are buried in the trench, and the water is filled once after covering the soil. This method is applicable to orchards with young or large spacing.
3. Coverage. The tree tray uses fresh material to cover the tree tray or put it between the rows of trees for fertilizer.
4. Tanning. The fresh materials are concentrated in the pits and then applied to the orchard.
Third, matters needing attention
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 dwarf or semi-agricultural green manure crops, high-stalk green manure crops should be harvested in time.
4, sowing perennial green manure crops, 4 to 5 years need to be ploughed and re-seeded.
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 manures are:
