Abstract

The invention relates to a corn straw compost for improving saline-alkali soil. The corn straw compost comprises corn straw powder, a flora suspension, ammonium nitrate, potassium dihydrogen phosphate, potassium chloride, zinc sulfate and water, wherein above florae comprise Bacillus thuringiensis, Alcaligenes faecalis, bacillus cereus and Cellulosimicrobium sp. 0707K4-3. The wheat field application method of the corn straw compost for improving saline-alkali soil is characterized in that: bacillus coagulans is cultured by a beef extract peptone medium and is prepared into the flora suspension by sterile normal saline, and wheat seeds are immersed in hydrogen peroxide to disinfect, is rinsed by sterile water, and then is immersed in the prepared flora suspension; and the compost is scattered to and uniformly mixed with flattened water-permeated soil, and the immersed wheat seeds are sowed in the soil. The corn straw compost of the invention has the advantages of improvement of physical and chemical properties of the saline-alkali soil, and wheat output improvement by carrying out degradation and microbial compost fermentation on corn straw; and the method of the invention, which allows the comprehensive utilization of the corn straw to be promoted, can be widely applied to the agricultural production and the saline-alkali soil improvement.

Description

technical field [0001] The invention relates to the comprehensive utilization of agricultural solid waste and saline-alkali soil improvement technology, in particular to a corn straw composting and wheat field application method for improving saline-alkali soil. technical background [0002] Northern my country is rich in straw resources, but the use of straw resources is not sufficient, and there is a phenomenon of idle burning of straw, which not only wastes resources but also pollutes the environment. Straw is a valuable renewable resource, and its full and rational use will be conducive to the sustainable development of my country's agriculture and rural economy, and will also avoid resource waste and environmental pollution caused by burning straw. [0003] At present, straw utilization methods mainly include: straw returning to the field, straw composting, production of feed, straw cultivation of mushrooms, production of biogas, production of green building materials, ...
