Problems solved by technology

[0002] At present, the irrigation and fertilization of orchards in my country is generally managed extensively and the fertilizer is single.
With the increase of planting years and unreasonable fertilization, the soil environment of the orchard continues to deteriorate, tree vigor is weakened, rot, ring spot and manganese poisoning occur frequently, and the yield and high-quality fruit rate decrease year by year
Among them, the deterioration of the orchard soil environment is mainly manifested in three aspects. First, the soil acidification is becoming more and more serious. The main reason is that the excessive application of chemical fertilizers leads to the serious accumulation of acid roots in the soil, and the calcium and magnesium ions in the soil colloidal particles are replaced by hydrogen ions. Soil acidification is increasing year by year; secondly, the number of bacteria and fungi in the soil is increasing, and the number of beneficial bacteria such as soil actinomycetes is decreasing, resulting in frequent occurrence of soil-borne diseases; thirdly, the input of organic fertilizer is seriously insufficient, and organic and The proportion of inorganic fertilizer is out of balance, and the proportion of large elements nitrogen, phosphorus, potassium and medium and trace elements is out of balance, resulting in soil salinization, compaction, poor air permeability, resulting in weak root system of fruit trees and poor absorption capacity
