First, high temperature deficiency and careful fertilization; the application of quick-acting phosphorus and potassium fertilizer in the early stage of fruit ripening can not only improve the character of the fruit, but also strengthen the disease resistance of the tree. However, the climate is usually monotonous, the temperature is high, the soil is not good, and the water is not fertilized after fertilization. In time, because the soil moisture is insufficient, the concentration of fertilizer absorbed by the root system is large, and the leaf edge of the roots is easy to emerge after fertilization. It shows the symptoms of salt damage, impairs the function of the leaves, affects photosynthesis, and then affects the character of the fruit, and the disease resistance of the leaves decreases. If it is rainy in the later stage, the leaf disease will be seriously serious, and even the leaves will fall prematurely. Fertilization should be applied and sprayed with plant electronic fertilizer when the soil is not sticky after irrigation, and the high-energy electrons and plant electron polarity induced by the photosynthesis of the plant itself. The principle is to improve the cell division, molecular synthesis and nutrient matching digestion level, accelerate the frequency of metabolism, and activate the plant nutrition control system to produce more than the fertilizer effect.

Second, deep application and shallow application; grape fertilization according to different fertilizer types, can be applied by deep application or shallow application, chemical fertilizer has a fast decomposition, easy to absorb, but also has the characteristics of volatile, growth period in the distance The grape main vines are ditched in the field of 0.8 to 1 meter, and then covered with soil. In the winter, the tree plant is dormant. In combination with the turning garden, the fertilizer and the topsoil are mixed and applied, and the farmland fertilizer is changed. The concentration is large, the decomposition is slow, the roots are stretched against the wall, and sometimes the rooting defects are easily caused. The application can also improve the topsoil. Deepen the traits, make the soil fluffy, reduce the knot and improve the drought resistance of the plants. Linyi Fertilizer Network Copyright

Third, the fertilizer should be reasonable; before the flowering, the young fruit period, the expansion period, timely spraying the grape cultivar introduced by the Taobao guide, can match the nutrition, so that the grape pedicle (the handle position) becomes thick and strong! The open transport channel allows the nutrients and water of the fruit tree to saturate and supply the flesh to expand. Fertilization at flowering stage should be based on phosphate fertilizer, with boron, zinc, iron and other medium and trace elements. When the length of new shoots is appropriate, the leaves should be less or not applied with nitrogen fertilizer. Otherwise, appropriate amount of nitrogen fertilizer should be applied. The coloring period is mainly phosphorus and potassium fertilizer. After the fruit is harvested, the appropriate amount of NPK compound fertilizer is applied to promote the early recovery of fruit trees and avoid premature aging. Grapes are fruit trees with more potassium. Potassium sulfate is better when potassium fertilizer is applied. In practice, it has been confirmed that the application of potassium chloride results in a thick skin, and the aftertaste has a ramie feeling, and potassium chloride should be applied as little or as little as possible.
