Abstract

The invention provides a preparation method of a compound organic fertilizer for a saline and alkaline land, relates to the field of fertilizers, and solves the problems that the water retention capacity is poor, the action time is short, and and long-acting and long-lasting treatment cannot be realized in the conventional organic fertilizer for a saline and alkaline land. The organic fertilizer includes 20-25 parts of excrements of people and livestocks, 35-40 parts of plant straws, 6-8 parts of bentonite, 5-8 parts of potassium fulvic acid, 8-10 parts of humic acid, 7-10 parts of porous light-weight volcanic rock, 10-15 parts of pharmacy leftovers from a pharmaceutical factory, 9-12 parts of a compound water-retaining agent, 3-5 parts of a sandy soil adhesive, 1-2 parts of bacillus subtilis, 1-2 parts of arbuscular mycorrhizal, 1-2 parts of trichoderma harzianum, 1-2 parts of salt-tolerance rhodopseudomonas capsulata, 1-2 parts of jelly bacillus, 1-2 parts of phosphate solubilizing bacteria, 1-2 parts of potassium bacteria and 1-2 parts of saccharomycetes. According to the invention, the soil structure of the saline and alkaline land is effectively improved, the fertility is improved, the saline and alkaline is reduced, the soil water retention capacity is improved, accumulation of salt is prevented, and the action is long-lasting.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a preparation method of compound organic fertilizer for saline-alkali land. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. 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. All kinds of saline-alkali soils are formed under certain natural conditions. The essence of their formation is mainly the redistribution of various soluble salts in the horizontal and vertical directions on the ground, so...
