Planting method for restoring soil by using full-biological fertilizer

Abstract

The invention discloses a planting method for restoring soil by using a full-biological fertilizer. According to the technical scheme, the planting method comprises the planting steps of S1, evenly spreading plant ash on the surface of planting land, then conducting soil turning and loosening on a planting area, and digging planting pits with the diameter being about 35 cm and the depth being about 30 cm through a shovel, wherein the distance between every two adjacent planting pits is about 1 m, the planting pit is funnel-shaped, and a semispherical indwelling groove is dug at the bottom of the planting pit so as to faciltate the growth of a plant root system; and S2, planting restoration plants in the planting pits, and applying a mixed fertilizer to the restoration plants in the germination and flowering period of the restoration plants; The planting method for restoring the soil through the full-biological fertilizer has the beneficial effects that the content of heavy metal in thesoil is effectively improved by planting the restoration plants, meanwhile, healthy growth of the restoration plants can be guaranteed through the prepared mixed fertilizer, the soil improving capacity is further guaranteed, and finally, various properties of the soil are further improved through the prepared soil conditioner so as to be more suitable for crop growth.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a planting method for remediating soil with all biological fertilizers. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals from rock weathering, animals and plants, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc.; [0003] Solid matter includes soil minerals, organic matter, and nutrients obtained by microorganisms through photoinhibition and sterilization. Liquid matter mainly refers to soil moisture. Gas is the air that exists in the pores of the soil. These three types of substances in the soil constitute a contradictory unity. Th...

Problems solved by technology

[0006] For this reason, the present invention provides a planting method for repairing soil with all biological fertilizers. By planting and repairing plants, the heavy metal content in the soil can be effectively improved. At the same time, the prepared mixed fertilizer will ensure the healthy growth of repair plants, thereby ensuring the ability to improve the soil. Finally, through the prepared soil improver, various properties of the soil are further improved, which is more suitable for crop growth, so as to solve the problem of soil acidification or alkalization in the prior art, crops cannot grow, and the content of heavy metals after contamination is high, and soil nutrients are lost sharply The problem
