Abstract

The invention discloses a special formula fertilizer for saline-alkali soil and a preparation method thereof. The fertilizer is prepared from the following components in parts by weight: 30 to 40 parts of urea, 50 to 80 parts of biomass straw, 10 to 20 parts of ammonium phosphate, 10 to 20 parts of furfural residue, 2 to 4 parts of bacillus subtilis, 3 to 6 parts of silicate bacteria, 2 to 6 parts of salt-tolerant azospirillum brasilense, 4 to 10 parts of biochemical fulvic acid, 10 to 20 parts of wormcast, 15 to 25 parts of desulfurized gypsum and 8 to 12 parts of soil conditioner. The prepared fertilizer has the effects of promoting crop growth, improving the soil quality of the saline-alkali soil and increasing the organic matter content of the soil, can better regulate the physical and chemical properties of the soil, and avoids re-accumulation of salt.

Description

technical field [0001] The invention relates to the technical field of formula fertilizer preparation, in particular to a special formula fertilizer for saline-alkali land and a preparation method thereof. Background technique [0002] At present, bio-organic fertilizer refers to a type of microbial fertilizer compounded with specific functional microorganisms and organic materials that are mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and have been harmlessly treated and decomposed. A kind of fertilizer with organic fertilizer effect. Bio-organic fertilizer has the advantages of reducing or replacing some chemical fertilizers and pesticides, restoring microecology, improving soil, restoring fertility, improving crop quality, no pollution to the environment, and no harm to humans and animals. With the enhancement of people's awareness of green environmental protection and the state's support for the organic fertilizer...
