Abstract

The invention provides a sandy soil saline-alkali soil structure conditioning method with a moire stone soil deep loosening agent. The method comprises the steps of soil deep loosening agent application and fertilizer application. The soil deep loosening agent comprises the components of, by mass, 35-45 parts of moire stone, 20-30 parts of limestone, 15-22 parts of a copolymer of vinyl acetate and maleic acid, 4-10 parts of bacillus mucilaginosus, 7-14 parts of citric acid, 2-5 parts of asparagus residue, 12-18 parts of sawdust, 0.5-0.8 parts of an acrylic acid / acrylamide copolymerized water retention agent, 4-9 parts of carbonized rice husk, 3-8 parts of hollyhock powder, and 2-7 parts of potassium dihydrogen phosphate. The method has the following advantages: after 6 months of sandy soil saline-alkali soil structure conditioning, soil pH value is 7.0-7.3, soil alkalinity is 3.4-5.2%, soil salinity is 0.31-0.38%, and soil water retention capacity and fertility are improved.

Description

technical field [0001] The invention relates to a method for regulating the soil structure of saline-alkali land, in particular to a method for regulating the soil structure of sandy soil saline-alkali land by using a chamoisite soil subsoiling agent, and belongs to the technical field of soil improvement. Background technique [0002] Sandy soil and saline-alkali soil have poor structure, poor water and fertilizer retention capacity, and less aggregate structure in the soil, which is not conducive to plant growth. [0003] Aiming at the problem of soil salinization, domestic and foreign scholars have carried out many researches, including under-mulch drip irrigation technology, concealed pipe drainage technology, alien soil technology and soil conditioner technology, etc. Although these technologies play a positive role in regulating salinized soil structure or improving crop yield and quality, some technologies have some limitations in their application. For example, under...
