First, the growth environment of alfalfa: the altitude of 100 to 2500 meters, the temperature of 5 to 35 °C in the mountains, dam areas and courtyards can be cultivated. Can be planted, but also potted or barrel, but the relative humidity is greater.
Second, soil quality: Xi Xi acidic soil, suitable for growth in the gas permeability pine acid rot leaf soil, it is best to use rot leaf soil in the forest to cultivate.
Third, digging pits: According to the size of the tree, dig deep 50 to 100 cm, 60 to 120 cm square pit to transplant.
4. Lifting and transportation: For a tree that is 1 meter high, a 60-centimeter tree tray is to be cut, and the roots outside the tree disk are all disconnected. The depth depends on the condition of the root system. Because there is no main root, the depth does not need to be too deep. When there are not many roots, it is usually between 30 and 50 cm. After the excavation, all 10 cm or more of the main feather leaves are cut off and 2 to 3 main leaves below 10 cm are left. After soaking in water with fresh moss, squeeze about 70% of the water. Wrap the roots and stalks of the pods and tie the ropes into wooden boxes. The space in the box can be filled with fresh moss and transported over long distances.
V. Colonization: Prepare rot and leaf soil with thiophanate-methyl or carbendazim in accordance with instructions for disinfection and sterilization. The tree body and roots were also sterilized by this method, and the bottom of the pit was filled with sterile rot. During the operation, while positioning the tree, sprinkling carbofuran on the leafy soil to kill the underground pests. After the planting, it is irrigated. Since it is a high-humidity environment, it should be covered with a black shade net to cover more than 60% of direct sunlight. Winter should also be frost-proof. Do not be afraid of drought, avoid water, so the drainage around the tree plate should be good. Depending on the geographical conditions, water can be sprayed on tree stems and tree trays every day to ensure humidity. After 30 days, three new main leaves can grow and other young leaves begin to germinate.
Six, fertilization:
1. Organic manure can be applied twice a year to fermented pigs and cattle sheep feces, each tree 20 to 50 kilograms.
2. Inorganic fertilizers can be applied every year except winter. The compound fertilizer is applied once every two months. According to the size of the tree, each time it is applied, it ranges from 0.1 to 1 kg. First, remove the layer of rot from the inside of the tree tray, sprinkle the fertilizer, and then cover the rot and leaf soil with water.
VII. Mid-term management: In order to make maggots grow fast, besides often spraying moisture on tree trays and stems, the main feathered leaves must be trimmed. When 10 to 12 main leaves are grown, the excess leaves of the old leaves should be cut from bottom to top. In this way, 2 to 3 main leaves can be grown each day. The height of the bucket can be increased by 10 to 15 centimeters per year, and it can be increased by more than 15 centimeters.
VIII. Pest Control: Earthworms are basically free from disease under natural conditions, but they also have diseases after transplanting and fertilizing. As long as thiophanate-methyl and carbendazim are used, the trees and tree trays are sprayed once a month to eliminate the disease. Insects mainly include ants and snails, and ants can be killed by baishu or kungfu pesticide sprays. Snail hi humid environment, the main damage to the tree leaves and tender stalks, can be used pesticides Worm Star and destroy Volna, etc. sprinkled on the surface of the tree disk killing and artificial capture.
IX. Precautions in Management:
1. Winter should be frost-proof;
2. Water spraying should not be carried out at high temperatures;
3. It is not necessary to spray the leaf surface water, especially at high temperature, the leaf surface water can easily cause the blade to droop too large and incomplete.
