Abstract

The invention relates to a preparation method of organic fertilizer gel particles for effectively improving soil compaction and provides a sodium carboxymethyl cellulose-polyvinyl alcohol-chitosan-silica cross-linking liquid. The cross-linking liquid is prepared through high-fiber support ingredients such as rice husk, peanut shells and straws as important aids, has three-dimensional network spacehole sizes, an adsorption capacity and a specific surface area better than those of the existing cross-linking agent and can store more organic substances. The granulation temperature and mode improve the binding force between the composite gel and base fertilizer granules and improve the swelling properties of the composite gel. The organic fertilizer gel granules can effectively improve the soil crust agglomeration, reduce the soil bulk density, absorb water, retain water, feed fertilizer and retain fertilizer. The test results show that the crop yield is high, the quality is good, the fruit is large, drought and waterlogging resistance is good, soil aggregate structure is stable, the water stability is 2mm-3mm and 20cm of the plough layer contains 70% or more of water stable soil granules with the sizes of 2-3mm.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a new method for effectively improving soil compaction. Background technique [0002] Soil is the basis for the growth and development of crops. As the amount of chemical fertilizers continues to increase, soil nutrients, especially organic matter, will decrease. Organic matter is a necessary component to form soil aggregates and prevent soil compaction, resulting in soil compaction and Ventilation is reduced. There are many existing solutions to soil compaction, such as simply using chemical substances for a short-term solution, but the residue of chemical substances will cause new problems; using decomposed animal manure can improve soil fertility and increase organic matter, but there are heavy metals There are hidden dangers of exceeding the standard and antibiotic residues; there are also straws scattered into the soil, and the soil is loosened by micro...
