Problems solved by technology

[0007] (1) The effect of reducing the salt content, soil pH and soil bulk density of carbonate-type saline-alkali soil is limited, and the speed of reducing salt is slow;
[0008] (2) Carbonate-type saline-alkali soil has poor water retention and water permeability, and poor soil aeration;
[0010] (4) While reducing the salinity and alkalinity of the soil, it cannot effectively fertilize the soil

Abstract

The invention provides a soil fertilizing and desalting method for a carbonate type saline and alkaline land by adopting a soil deep scarification agent. The method comprises application of the soil deep scarification agent, wherein the soil deep scarification agent comprises the following components in parts by mass: 12-20 parts of scale stones, 10-14 parts of starch-acrylamide, 2-5 parts of actinomycetes, 4-7 parts of phosphobacteria, 8-13 parts of ammonium humate, 14-24 parts of straw powder, 0.4-0.9 part of a cellulose grafted acrylic water-retaining agent, 4-16 parts of weathered coal and 17-25 parts of black alum. The method provided by the invention has the benefits that for fertilizing and desalting of the saline and alkaline land six months later, soluble salt of 100 g of soil comprises 0.08-0.13 mg of soda and 0.20-0.25% of total salt content of soil; the utilization ratios of a nitrogen fertilizer and a phosphorus fertilizer in soil are improved by 13-16% and 20-25%, respectively; the content of replaceable calcium oxide in soil is improved by 40-50%.

Description

technical field [0001] The invention relates to a method for fertilizing and reducing salt in saline-alkali soil, in particular to a method for fertilizing and reducing salt in saline-alkali soil using a soil subsoiling agent, and belongs to the technical field of soil improvement. Background technique [0002] The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] At present, domestic methods for soil fertilization and salt reduction in saline-alkali land include: ①Physical methods: leveling the land, deep plowing and drying, loosening the soil in time, raising the terrain, and improving the soil in micro-area; ②Water conservancy engineering methods: supporting drainage and irrigation, storing light [0004] Salt, irrigation salt, underground salt drainage; ③ chemical methods: gyp...
