Abstract

The present invention provides a soil improvement method for clay soil type saline-alkali land using a hydrolyzed polyacrylonitrile soil subsoiling agent. The improvement method includes application of the soil subsoiling agent, application of fertilizers, mechanical subsoiling of the soil, and irrigation. Soil subsoiling agent, including 16-22 parts of hydrolyzed polyacrylonitrile, 10-15 parts of Kunshan stone, 4-8 parts of Bacillus lateralis, 3-9 parts of phosphorus solubilizing bacteria, 5-11 parts of amino acid salt, 6-6 parts of biochar 14 parts, calcium-based bentonite 4-13 parts, humic acid water-retaining agent 0.6-1.2 parts, ammonium bicarbonate 9-16 parts, corn straw powder 11-19 parts, chicken manure 25-35 parts. The invention has the beneficial effects of reducing the pH, soil salinity and soil bulk density of clay soil type saline-alkali soil; improving soil air permeability and water retention capacity; increasing the number of microorganisms in saline-alkali soil; and improving the fertility of clay soil-type saline-alkali soil.

Description

technical field [0001] The invention relates to a soil improvement method for saline-alkali land, in particular to a soil improvement method for clay soil type saline-alkali land by using a hydrolyzed polyacrylonitrile soil subsoiler, and belongs to the technical field of soil improvement. Background technique [0002] Saline-alkali soil particles are divided into sand grains and clay grains according to the basic particle size. Clay-dominated soil is called clay soil, commonly known as clay. Clay soil saline-alkali soil lacks large pores and has poor air permeability, which is not conducive to plant growth. [0003] At present, the measures widely used at home and abroad to control saline-alkali land include water conservancy improvement measures (including irrigation, drainage, silt release, rice planting, anti-seepage, etc.), agricultural improvement measures (including land leveling, improved tillage, soil application, fertilization, sowing, etc.) , crop rotation, interp...
