Seriously affecting the sustainable development of the apple industry.

The degradation of soil ecological environment is the root cause of the reduction of apple quality and yield, and especially finished fruit orchards face the problem of soil degradation. Taking Shandong Qixia apple producing area as an example, the soil degradation is concentrated and shown as follows: 1) the organic content is low. The average content of organic matters in the soil is 0.9 percent. 2) And (5) hardening the soil.

Most of the soil is coarse in texture, poor in structure and compact in soil, and 63% of the volume weight of the apple orchard soil is not in an appropriate range. 3) Nutrient imbalance. Deficiency of trace elements and shortage of calcium and magnesium. 4) And (5) soil acidification. The pH value of 64.6% of the apple orchard soil is less than 5.4. 4) The secondary salinization of soil is aggravated. 5) The apple has low density of absorbed roots and weak absorption capacity. 6) Soil microorganism ecological imbalance and soil-borne diseases are aggravated.
