How is the soil consolidation in the orchard caused?

The growth and development of fruit trees needs a good soil environment, and soil consolidation often occurs in orchard management, which leads to the phenomenon of yellow leaves and fallen leaves in all kinds of fruit trees, which seriously affects the yield of fruit trees and brings serious losses to fruit farmers. So what causes the soil consolidation in the orchard? Let's take a look.

1. The soil texture is too sticky.

The soil in the orchard is too sticky, and there is more clay in the clayey soil, coupled with the shallow tillage layer, less capillary pores in the soil, poor ventilation, water permeability and temperature increase, and it is easy to block the pores after rain or irrigation. therefore, it is very easy to cause soil surface crust, which is soil consolidation.

2. insufficient content of organic matter.

The organic matter in the soil is not replenished in time, and the content of soil organic matter is low, which will lead to the deterioration of the structure and affect the activity of microorganisms, thus affecting the formation of soil aggregate structure, resulting in soil acidity and basicity is too large or too small, resulting in soil consolidation.

3. Long-term single application of chemical fertilizer

Long-term application of chemical fertilizer without organic fertilizer in the process of fertilization will lead to the continuous decrease of soil organic matter content, lack of humus supplement, soil consolidation and cracking. At this time, the main reason for orchard soil hardening, nitrogen fertilizer can promote plant growth, phosphorus fertilizer can promote root development, and potassium fertilizer can improve yield, so many fruit farmers apply them blindly in fertilization. This will seriously damage the soil aggregate structure, affect the activity of microorganisms, lead to the formation of soil aggregate structure, resulting in soil consolidation.

4. farming operation leads to the destruction of soil structure.

Because in mechanical tillage, the soil aggregate structure is destroyed, and only a small part of the fertilizer applied every year is described in detail by fruit trees, and most of the fertilizer is fixed by the soil, resulting in a large amount of salt deposition and soil consolidation.

5. Accumulation of harmful substances and soil erosion

Groundwater and industrial waste water in some areas contain a lot of toxic substances, and some fruit growers use these water for a long time. Over time, excessive accumulation of toxic substances in the soil will cause soil consolidation. In addition, the fine soil particles in the topsoil layer are taken away after the wind-sand and rainstorm, which destroys the soil structure and causes soil consolidation.
