Abstract

The invention aims to provide a saline-alkali soil improver containing glomus mosseae and an improvement method, aiming at solving the problems existing in improvement of saline-alkali soil by the existing biotechnology. The saline-alkali soil improver is composed of glomus mosseae, iron tailings and organic soil, the ratio of glomus mosseae liquid to the iron tailings to the organic soil is 2 mL:2-2.5 g: 1.5-1.8 g, and the concentration of the glomus mosseae liquid is 1-9 * 107 CFU / ml. According to the simple saline-alkali soil improvement method, the glomus mosseae infects plant roots to form arbuscular mycorrhizal symbionts, the iron tailings are used as an improver, a synergistic effect is achieved on plants planted in saline-alkali soil, and the plant biomass is improved while the purposes of improving the saline-alkali soil and improving the soil availability of the saline-alkali soil are achieved.

Description

Technical field [0001] The invention belongs to the field of saline-alkali soil improvement, and in particular relates to a coastal saline-alkali soil improver and an improvement method using iron tailings and microorganisms. Background technique [0002] Saline-alkaline soil is a kind of soil that is harmful to the normal growth of crops. It is the general term for saline soil, alkaline soil and other salinized and alkalized soils. Usually the salt content of saline-alkaline soil is above 0.1%-0.2%, or the soil colloid absorbs a certain amount of exchangeable sodium, and the alkalinity is above 15%-20%. Under drought conditions, the soil is easy to compact and reduce water permeability, which will seriously affect The absorption of water and nutrients by plants is extremely detrimental to the growth and development of plants. At present, people pay more and more attention to the development of saline-alkali soil treatment and improvement technologies. [0003] The technology for...
