Abstract

The invention relates to an organic fertilizer for ameliorating salinity and alkalinity of soil and eliminating soil hardening and a preparation method of the fertilizer. The organic fertilizer for ameliorating salinity of the soil and alkalinity and eliminating soil hardening provided by the invention reduces salinity and alkalinity of the soil while improving fertility of the soil, improves physical and chemical properties of the soil, increases a granular structure of the soil, increases permeability of the soil, improves water retention, fertilizer retention and gas permeability of the soil, greatly increases available nutrients that can be directly absorbed by plants in the soil, eliminates soil hardening, improves resistance to insects and stress of the plants, significantly improvescomprehensive productive capacity of cultivated land, and can be widely used in the technical field of agricultural fertilizers.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an organic fertilizer for improving salinity and eliminating soil compaction and a preparation method thereof. Background technique [0002] Saline-alkali land is the general term for all kinds of saline soil, alkaline soil and salinized and alkalized soil. According to the amount of saline-alkali content in the soil, it can generally be divided into three types: mild, moderate and severe saline-alkali land. The sodium ion content of severe saline-alkali land is relatively high. Salts will even be precipitated on the soil surface, causing soil compaction, resulting in low yield or failure to grow crops, or even death. Soil salinization has seriously affected the regional ecological environment and food production. In recent years, with the improvement of people's awareness of sustainable development and the promotion of the government, more and more scientific re...
