Cultivating a well-developed root system will greatly help increase yields and yields of vegetables. How to cultivate a developed root system? The summary is as follows:
1. Deeply pour the soil and reapply organic fertilizer. For example, melon vegetables require large amounts of fertilizer, so organic fertilizers with long-lasting fertilizer and full nutrient content must be applied. Deep soil can be more than 30 cm, mu Shi chicken duck manure 10 to 15 cubic meters or cattle and sheep pig manure 25 to 30 cubic meters. Organic fertilizers must be thoroughly cooked before they can be used.
2. Formula Scientific fertilization. Different fertilizers have different effects on root growth. For example, calcium directly affects the growth of root apical meristems. Zinc determines the growth rate of root tips. Phosphorus can promote root cell division, proliferation, and extension. Therefore, both superphosphate fertilizer and fertilization in cultivation should pay attention to the application of superphosphate and zinc sulfate. If a certain amount of vinegar is incorporated into the calcium superphosphate fertilizer, calcium acetate having a certain solubility can be formed to enhance the absorption of calcium by the crop.
3. To expose pods when planting, apply biological bacterial fertilizer. The root system of Solanum vegetables has good aerobicity, so the planting should not be too deep, and the dew exposure is beneficial to the development of the root system after planting. Root diseases are one of the major problems in the production of melons and solanaceous vegetables in greenhouses in recent years. The application of biological bacterial fertilizers can use bacteria to prevent root diseases and at the same time promote root and root culture. Vegetables form a strong root system.
4. To protect the blades. Rooted on leaves, it is very important for the root system to protect the leaves. First of all, sparsely. Because the nutrition of the upper leaves of the fruit mainly supplies the fruit growth, the nutrition of the lower leaves of the fruit mainly supplies the root growth. If the leaves are removed early and the roots are weak, the ability of the root to absorb the fertilizer and water is reduced. Secondly, we must also focus on the physiological needs and plant growth at different stages of the crop, combine spraying with foliar fertilizers for pest control, increase the photosynthetic efficiency of the leaves, and raise the roots with leaves. Yellow leaves can be sprayed with iron and zinc foliar fertilizer. When the old yellow leaves were sprayed with cytokinin and foliar fertilizer. In the early stage, 300 times urea was sprayed, and 500 times more potassium dihydrogen phosphate was sprayed. In the whole cultivation season, it can be sprayed many times with 6,000 times more love and grow strong trees.
5. Reasonably water top dressing. In the low ground temperature or clay ground flooding irrigation, the damage to the crop roots is very obvious. After a large flood, hairy roots and yellow leaves often occur. These capillary roots are the main organs that absorb nutrients. Therefore, small water should be poured under the membrane, and the micro spray irrigation system can be installed conditionally to reduce the damage to the root system caused by watering.
