Method for efficiently and rapidly retrieving green and improving soil pH value by spray-seeding robinia pseudoacacia on exposed rock wall of shale

Abstract

The invention discloses a method for efficiently and rapidly retrieving green and improving soil pH value by spray-seeding robinia pseudoacacia on the exposed rock wall of shale, and belongs to the technical field of ecological restoration and soil improvement. Mixed microorganisms, an organic fertilizer and soil are spray-seeded onto the exposed rock wall of the shale through a borrowed soil spray-seeding method, the green-covered plant is robinia pseudoacacia, and the purposes of efficiently and rapidly retrieving green and improving the soil pH value are achieved. The mixed microorganisms are composed of Kocuria X-22, microbacterium X-26, bacillus X-28, and microbacterium X-18, and the mixed microorganisms are added into the organic fertilizer and the soil with a fermentation bacterialsolution. The weight ratio of the mixed microorganisms to the organic fertilizer to the soil is 1:1:8. By means of the method, synergism of microbial flora and leguminous nitrogen-fixing bacteria is achieved, rapid growth of the robinia pseudoacacia on the exposed rock wall of the shale is promoted, the robinia pseudoacacia soil organic matter content, available phosphorus content and pH value canbe significantly improved, the soil fertility is improved, the application dose of the chemical fertilizer is reduced, and a low-cost efficient new method can be provided for efficient and rapid green retrieving of the exposed rock wall of the shale.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for spraying black locust on exposed rock walls of shale for efficient and rapid regreening and improving soil pH. Background technique [0002] Soil is the foundation of forestry production, an important carrier of nutrients in material cycle and energy flow, and one of the important factors affecting the environment. With the advancement of human civilization, a series of activities such as mining and road construction have caused ecological problems such as the destruction of mountain vegetation, exposed rock walls, and increasing soil erosion. Human development and utilization of land will not only change the soil structure, but also change the soil fertility and activity, etc., which has a serious impact on the cycle of soil materials. [0003] Soil acidity and alkalinity are important indicators for evaluating soil nutrients, and have extremel...

Problems solved by technology

Soil compaction will cause the roots of crops to have difficulty breathing, thereby reducing the number of roots, the shape becomes short and thick, and the roots are not deep, which will prevent the plants from getting sufficient water and nutrients

In addition, the compacted soil will also accelerate the loss of soil moisture, and the soil's drought resistance will also decrease, which will not be conducive to the growth of plants.

[0005] In the prior art, lime is usually used to neutralize the active and latent acids in the soil, but studies have shown that no matter whether lime is applied or not, soil reacidification exists, but the application of lime accelerates the reacidification of soil

In addition, excessive lime application can also cause problems such as soil compaction or nutrient loss.
