Improved soil for planting green plants

Abstract

The invention discloses improved soil for planting green plants. The improved soil is characterized by comprising, by weight, 10-30 parts of saline-alkaline soil, 1-15 parts of polyacrylamide, 1-20 parts of bentonite, 40-77 parts of waste bacteria sticks and 0.001-0.003 part of bacillus. The improved soil has the advantages that the improved soil can be used for changing the vegetation growth environment to avoid environment pollution and can also supplement a large amount of potassium, organic substances containing various stable trace elements are stable and have comprehensive nutrients, andwhen the improved soil is applied to planting and cultivating, the survival rate and growth speed are high. Compared with conventional saline-alkali soil improvement materials, the improved soil hasthe advantages of multifunctionality, low price, and convenience in production and use.

Description

technical field [0001] The invention belongs to the field of green planting, and in particular relates to an improved soil for green plant planting. Background technique [0002] Due to geological and climatic reasons, there are large areas of saline-alkali land in northern my country, especially in North China. These saline-alkali lands are not only harmful to agricultural production, but also have obvious effects on urban greening in today's large-scale urban construction. Negative effects. [0003] At present, the improvement methods of saline-alkali land are as follows: 1) deep plowing and deep plowing: deep plowing of soil promptly turns over the salinity in the topsoil to the bottom of the plow layer, and turns the soil with less salt in the lower layer to the surface. Tilling can loosen the plowing layer, cut off the soil capillary, reduce the evaporation of soil water, and effectively control the return of soil salt; 2) Increase the application of organic fertilizers...

AI Technical Summary

Problems solved by technology

With the enhancement of people's economic awareness and environmental protection awareness, the research and development of high-efficiency and low-consumption green and environmentally friendly soil improvers has become the focus of research, but the soil improvers currently used for saline-alkali soil improvement are usually not environmentally friendly.

[0004] Waste mushroom sticks are the remaining waste after the production of edible fungi. Since the total output and total export volume of edible fungi in my country have leapt to the first in the world, at least 4 million tons of waste mushroom sticks are produced every year. The traditional method of disposal is to discard or burn them. , which not only causes a waste of resources, but also leads to the growth of mold and pests, increases the number of harmful spores and pests in the air, and pollutes the environment

As a kind of agricultural waste biomass resources, it has high organic matter content, complete variety of available nutrients, and contains a variety of plant growth promoting substances. It is a biological fertilizer resource with great potential. The slag is loose, has good air permeability, and the gap between the total pores and water-holding pores is large. It can be used as a garden cultivation substrate, but the EC value in the fungal slag is high, which is easy to increase the salt content in the soil, which is not conducive to the planting of green plants.
