First, fertilizer and water management
At present, Ya pear fruit has begun to expand and is in the period of rapid expansion of the first fruit. During this period, flower buds are in the period of physiological differentiation, with rapid root growth and active absorption. The demand for water and fertilizers increases. The top dressing should be watered in a timely manner to supplement the nutrients needed by the tree. Top-dressing fertilizers should be high-nitrogen, medium-phosphorus, high-potassium three-element compound fertilizers and all-element fertilizers with multiple trace elements, or organic, inorganic, and biological bacteria fertilizers. The amount of fertilizer should be based on the number of fruits and tree vigor, and it is generally controlled at about 30% of the annual fertilization amount. The fertilization method usually adopts the digging radiation groove fertilization method, and the length of the ditch is not less than the radius of the tree projection. Appropriate amount of water after topdressing can promote the absorption of fertilizer, but prevent flooding to prevent flooding. At the same time, the effect of foliar spray fertilizer is better.
