Embodiment 1

[0018] A method for preparing a soil composition that improves soil aggregate structure, comprising:

[0019] 1) prepare a kind of soil composition, the component of this soil composition comprises cement, greening soil, chemical fertilizer, greening substrate A, B;

[0020] 2) Then first add the fermented bark to the soil composition, then add vermiculite and perlite to form a soil composition of aggregate structure, that is, to form a spray material; wherein the bark will be crushed into fibrous form before fermentation , which is added into the soil composition to form a supporting framework of the aggregate structure, utilizes the expansibility of vermiculite and perlite to form the aggregate structure, and obtains the soil composition of the aggregate structure.

[0021] After in-depth proportion research and soil effect test, it is found that when the components in the soil composition are proportioned according to the following table, it has the best improvement effect ...

Embodiment 2

[0024] Application of a Soil Composition for Improving Soil Aggregate Structure

[0025] 1) Mix the soil composition, binder and seeds forming the aggregate structure, add water and stir, and then use a wet sprayer to spray it on the area to be greened;

[0026] 2) After spraying, spray the water-retaining agent on the spraying layer first, and then cover the film. The content of the water-retaining agent should be selected according to the local climate, so as to store water when there is water, release water when there is no water, and prevent erosion at the same time And evaporation, improve the germination rate and survival rate in the early stage of spraying.

[0027] The soil composition with aggregate structure has many advantages. It has a suitable pore size distribution and can adjust the water, fertilizer, air, heat and other factors in the soil to make it beneficial to the growth of crops. The soil with structure is the soil with good cultivability. At the same tim...

Abstract

The invention provides a preparation method and an application of a spray-seeding material for improving soil aggregate structures. The preparation method of the spray-seeding material comprises the steps as follows: combining and preparing soil composition, then, adding fermented bark to the soil composition, and adding vermiculite and perlite to form the soil composition with an aggregate structure. During application, the soil composition adopting the aggregate structure is mixed with a binder and seeds, water is added, stirring is performed, and the obtained mixture is spray-seeded on a to-be-greened area by a wet spraying machine; a water retaining agent is sprayed on a spray-seeding layer after spray-seeding firstly, and then, the spray-seeding layer is covered with a film. The material composition can improve the aggregate structures of soil and regulate factors such as water, fertilizer, gas and heat in soil, so that the soil is beneficial to growth of crops, the structured soil is soil with good cultivation performance, meanwhile, the structured soil can better absorb rainwater, and surface layers of soil are not prone to erosion, scouring and washing.

Description

technical field [0001] The invention relates to the field of proportioning of spraying materials for greening, and more specifically, to a preparation method and application of spraying materials for improving soil aggregate structure. Background technique [0002] The spraying technology is a new type of technology suitable for greening of rock-soil slopes with a high degree of weathering and soil-interbed rock slopes. It is especially suitable for slope protection and greening of roads, railways, and river slopes. It uses a special jet machine to spray organic substrates such as grass seeds and water-retaining agents onto the slope, and the organic materials are tightly combined with the slope under the action of pressure to form a substrate layer for plant growth and development. The requirement of soil thickness for spraying depends on the specific conditions of the slope, usually 10-30cm. Add bermudagrass, tall fescue, amorpha and other grass species into the spray to ...
