Problems solved by technology

No matter the improved technology mentioned above, there are disadvantages of high cost and slow effect
[0004] my country is a large agricultural production country, every 1Kg of grain produced will produce 1.5-2Kg of straw, and the straw produced is mainly processed through incineration, which not only causes waste of data, but also seriously affects the environment

Abstract

The invention discloses a method for using agricultural straw to improve saline-alkali soil and belongs to the technical field of soil improvement. The method includes: using corn straw and bran to make culture media; loading the culture media into a polyethylene bag, performing inoculated culturing after sterilizing and cooling until mycelia mature; furrowing during a lay-up period, removing the mature mycelia from the bag and placing the same in furrows, covering soil, compacting and watering, wherein the intervals among the mycelia are 4-6cm; loosening soil two days after watering and mulching, controlling soil temperature at 5-18 DEG C and moisture at 70-85%; fruiting 22-28 days after mulching, and collecting the mature edible mushrooms; covering the edible mushrooms which stop growing when the temperature is below 3 DEG C to allow the mushrooms live through the winter naturally; watering and mulching after thawing the next year, and fruiting until crop sowing in spring. The method has the advantages that the mycelia are planted during the lay-up period by using the waste agricultural straw, nitrogen phosphorus, potassium and organic matter contents of farmlands are increased, soil alkaline is lowered, the pH value of the soil ranges from neutral to sub-acidity, and crop growth is benefited.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and relates to a method for improving saline-alkali soil by using agricultural straw. Background technique [0002] my country has a vast territory, but a considerable part of the arable land belongs to saline-alkali land. Due to heavy saline-alkali, low soil nutrient content, and soil compaction, the yield of crops is low in saline-alkali land, so many places can only let the saline-alkali land go barren. [0003] The traditional method of improving soil salinity is to adopt comprehensive farmland technical measures, including modern water conservancy construction technology, agricultural technology, and chemical improvement technology; among them, water conservancy construction technology mainly includes open ditch drainage, underground pipe drainage, shaft irrigation and drainage, Canal anti-seepage and drip irrigation salt technology; agricultural technology includes traditional dry ...
