Tea tree seedling drought prevention and drought measures
The key to the development of the newly developed good-quality tea plantations is to grow seedlings and grow into gardens. The key point is whether or not they can safely pass through droughts in summer and autumn. Therefore, how to ensure seedlings to fight drought and drought is crucial. To cover, cover, irrigation, apply, cure, and remove six aspects: Cover: insert wheat straw or straw higher than tea seedlings on the surface of tea seedlings. In the soil, shades are avoided to prevent direct sunlight and prevent dry hot winds from causing damage. This method is based on local materials. The method is simple and effective. Cover: It can be covered with straw, farmland, dregs, etc. It can not only keep water and soil, but also improve the soil and play a good role in drought prevention and drought. Irrigation: When there is a high temperature and drought, it is best to sprinkling irrigation under conditions, or watering manually. Sprinkling can be done in the evening, and the amount of spray depends on the degree of soil drying. Watering can be mixed with decomposing and thin human urine, and the drought resistance is better. Shi: Fertilization can also improve drought resistance. When the drought comes, or has suffered drought, it will be better before the drought. After the tea seedlings obtain nutrients, they accelerate the growth of the plants, especially the root system of the tea plants, and improve the water absorption capacity and drought resistance. Usually human urine or animal manure, pay attention to dilution, 10 days or a half months. Treatment: young tea, growth fat, susceptible to pests and diseases, should be promptly checked, the right medicine, pest control, ensure that the tea seedlings grow robustly, help to improve drought resistance. In addition to: weeds grow in summer, compete with water for tea to compete for space, increase soil evaporation, and may accelerate pest damage. In the production, we can perform shallow plowing and weeding to cut off the capillaries of the soil. However, we must pay attention to the distance from the tea seedlings to the mowing and not to hurt the roots.
