What are the problems that should be paid attention to when applying basal fertilizer to fruit trees?

1. According to the age of the tree, different types of fertilization are used: For young fruit trees, because the root system is not well developed, in order to avoid the saplings, generally, in accordance with the size of the crown, a circular fertilization method is used at the root. For adult fruit trees, an orchard with good lyrics can be applied deep into the hole or applied with acupuncture points, but the large tree is applied 0.8 meters away from the dense roots to induce new roots to extend outward.

2. Different types of trees and growth rates determine the amount of fertilization: different tree species, growth potential, and soil fertility require different amounts of fertilizer. The output of fruit trees with a long age and high yield is larger, and the application amount of basal fertilizer is greater. Poor soil and low fertility orchards require large amounts of fertilizer and should be applied in multiple ways. Saplings and fertile orchards should be relatively sparse. However, no matter what kind of fruit trees, basal fertilizer should be dominated by organic fertilizer, such as adult grapes, 2,000 kg of fruit per mu, 4000 kg of fertilizer should be applied to high-quality livestock. Adult pear trees can be used to produce 40-50 kg of ash compost per plant, with 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 proportion of fertilization, such as peach, each producing 100 kg of fruit should be applied 0.5 kg of nitrogen, phosphorus 0.3 kg, potassium 0.2 kg. In areas where the soil is poor, multi-element complex trace elements must be applied.

3.Response to disasters, grab fertilizers: For the orchards that lack lyrical moisture, apply organic active liquid fertilizer to apply fertilizer to trunks. For example, Huimanfeng or Zhuangfuxing Active Liquid Fertilizer per acre can be used to dilute the water to 30 times in the base of the trunk at 50 to 100 cm. Brushing can quickly penetrate the bark and be absorbed by fruit trees.
