Abstract

The invention provides a saline-alkali soil improver as well as a preparation method and application thereof. The preparation method of the saline-alkali soil improver comprises the following steps: (1) mixing biochar, leguminous auxiliary materials, a yeast inoculant and water according to a weight ratio of (100-300): (50-350): (1-10): (1000-3000), fermenting the mixture for 80-120 days to obtaina fermentation mixture, and carrying out solid-liquid separation on the fermentation mixture to obtain a fermentation filtrate and a fermentation product; and (2) mixing the fermentation filtrate, the fermentation product and humic acid according to a weight ratio of (10-30): (5-15): (1-10) to obtain the saline-alkali soil improver. The saline-alkali soil improver disclosed by the invention can realize multiple effects of resource utilization of agricultural wastes, improvement of saline-alkali soil, improvement of soil performance and improvement of corn growth, and has the characteristics of being good in fertilizer retention effect, environment-friendly and safe.

Description

technical field [0001] The invention relates to the field of environmental functional materials, and more specifically, to a saline-alkali soil improver and its preparation method and application. Background technique [0002] Due to serious soil erosion in the Yellow River floodplain, saline-alkali soil is formed, with low organic matter and nutrient element content, barren soil and severe alkalization. Salt-alkali stress will inhibit plant seed germination and plant growth, resulting in low primary productivity, low vegetation coverage, greatly restricted agricultural development, and wasted a lot of land resources. In recent decades, due to agricultural irrigation methods and intensified human activities along the Yellow River, the salinization of beach soil has increased, and ecological functions have been seriously damaged, which has caused huge social and economic losses. Effective measures must be taken to restore the damaged soil . Therefore, establishing a set of ...
