1. Matrix selection: ramie has low requirements on soil, and any soil can grow basically. But in the deep, strong drainage capacity, and fertile neutral soil, the yield will be higher. When you configure the soil, you should match more, you can mix the bean dregs, rotten leaf soil, garden soil, and some small stones, increase the permeability of the soil, but also ensure the basic nutrients it needs for growth.
2. Temperature management: the best temperature for ramie growth is from 16 ℃ to 30 ℃. If the temperature is lower than 7 ℃ in winter, the roots will be frozen. It is necessary to cover the soil layer or straw for winter. If the temperature is too high in summer, it will affect its flowering.
3. Water management: Ramie growth needs a lot of water, which is suitable for growing in the soil with water content of 21% to 25%, and the maximum soil water content cannot exceed 84%, otherwise it will affect the root respiration of ramie..
4. Nutrient management: it needs more nutrients during the growth period. 24kg of nitrogen fertilizer, 12kg of phosphorus pentoxide and 16KG of oxidized nitrogen can be applied to each mu. Before overwintering, organic fertilizer such as human and animal manure mixed with rotten leaf soil can be deeply buried around ramie.
1. Cutting: it is suitable for cutting in summer. Before cutting, potassium permanganate should be used to disinfect the soil. Pick the cuttings before the sun rises. Cut off the big leaves after the cuttings are collected. After about four hours in a cool and ventilated place, cuttings are placed in about 3cm of soil.
2. Winter: the winter temperature needs to be kept at about 10 ℃. The method of covering soil can be used for heat preservation, covering about 8 cm deep soil to prevent freezing damage.
1. Root rot: too much water or too much water in the garden will lead to poor permeability of soil, which will inhibit the respiration of roots, thus leading to root rot, which can be treated with Bordeaux solution.
2. Longicorn: when the quantity is small, the method of artificial killing can be adopted. The adults can be killed after shaking down from the branches, and the larvae can be killed with sharp tools or collected and burned in a centralized way. When the amount is large, we can take medicine treatment, spray dichlorvos evenly on the surface of the plant after mixing with water, and increase the spraying times properly.
1. Hydroponics: no hydroponics. Ramie has a great demand on the permeability of soil. In general, excessive watering or ponding in the field will lead to the root rot of ramie. If hydroponics, it will completely inhibit the respiration of ramie roots, and in serious cases, it will lead to plant death.
2. Whether it can be planted: it can be planted. Ramie is suitable for growing in the deep and fertile soil, the amount of potted soil is less and the fertility is not stable, so it is suitable for planting in the field.
