Different fertilization methods are used according to the age of the tree. For young fruit trees, because the root system is not well developed, in order to avoid damage to the young roots, the annular fertilization method is generally adopted at the root according to the size of the canopy. For adult fruit trees, well-characterized orchards can be applied deep in the hole or applied with acupoints, but the large trees should be applied 0.8 meters from the roots to induce the new roots to extend outward. Where there are experience and conditions, it can be fertilized by open-plan ditch according to the growth direction of the fruit tree root.
Different types of trees and growth factors are determined to determine the amount of fertilizer applied. Different tree species, growth and soil fertility require different amounts of fertilizer. The fruit yield of the fruit trees with long tree length and high yield is larger, and the application amount of base fertilizer is larger. Orchards with poor soil quality and low fertility require large amounts of fertilizer and should be applied more. Young trees and fertile orchards should be relatively small. But no matter what kind of fruit trees, the base fertilizer should be based on organic fertilizer, such as adult grapes, 2000 kg of fruit per mu, should be applied 4000 kg of high-quality livestock fertilizer. Adult pear trees can be used for 40~50 kg of decomposed ash and fertilizer, 1 kg of phosphate fertilizer, 0.5 kg of potassium fertilizer or 1 kg of compound fertilizer. At the same time, we must also pay attention to the ratio of fertilization, such as peach trees, each application of 100 kg of fruit should be applied 0.5 kg of nitrogen fertilizer, 0.3 kg of phosphate fertilizer, 0.2 kg of potassium fertilizer. The ratio of nitrogen, phosphorus and potassium in citrus is 1:0.5:1. Where the soil is poor, it is also necessary to apply multi-component trace elements. Only in this way can scientific fertilization be achieved and economically effective.
Resist the strain and grab the fertilizer. For the orchard with insufficient sensation, the organic active liquid fertilizer can be used to apply the tree trunk for fertilization. For example, 250 ml of active liquid fertilizer or 30 ml of water can be used for 30-100 cm of the root of the trunk, which can quickly penetrate the bark. Absorbed by fruit trees. It can also be sprayed on the trunk branch with Huimanfeng or Zhuangfuxing active liquid fertilizer 200~300 times before the fruit tree sprouts. One can play the effect of supplementing fertilizer; the second can relieve the drought. In addition, if you encounter the spring rain, you should grab the fertilizer in the orchard ground after the rain, and then plough the plough to bury it deeply, and also play the role of quick-acting fertilizer.

Fruit tree grabbing method for applying base fertilizer
At present, it is imperative to seize the opportunity of grievance relief, and to mobilize and replenish the fruit tree base fertilizer. It is imperative that all localities should use a variety of methods to supplement the fruit tree with the base fertilizer and apply the base fertilizer.
