Abstract

The invention discloses a fertilizer synergist capable of improving acid soil for oilseed rape and a preparation method for the fertilizer synergist. The fertilizer synergist is prepared from the following raw materials in parts by weight: 2-3 parts of zinc sulfate, 44-46 parts of zeolite, 60-80 parts of modified phosphate rock powder, 4-5 parts of glauconite, 18-20 parts of sugar beet pulp, 14-16 parts of furfural residues, 5-6 parts of calcium hydrogen phosphate, 3-4 parts of attapulgite clay and an appropriate amount of water. According to the fertilizer synergist disclosed by the invention, added raw materials of furfural residues, glauconite powder, modified phosphate rock powder, and the like are combined with the fertilizer for use, so that elements of nitrogen, phosphor and the like in soil can be released, the contradiction of between nitrogen and phosphorus shortage and insufficient nitrogen and phosphorus supply to the soil is relieved, calcium, potassium, iron and other salt-based irons can be provided, the soil PH value is increased while growth needs of the oilseed rape are ensured, the content of exchange aluminum in soil is reduced, and the good effect of improving the acid soil is achieved.

Description

technical field

[0001] The invention relates to the technical field of fertilizer synergists, in particular to a fertilizer synergist for rape that can improve acidic soil and a preparation method thereof. Background technique

[0002] Rapeseed is an important economic crop in my country. It not only has high edible value, but also can be used as an excellent feed for livestock and poultry. At the same time, it can be processed and extracted for daily life and industrial use. At present, there are many kinds of special fertilizers for rape on the market, but the problems of low utilization rate of fertilizers and damage to soil physical and chemical properties cannot be avoided.

[0003] γ-polyglutamic acid is an anionic polyamino acid produced by microbial fermentation in nature. Its molecular chain has a large number of free side chain carboxyl groups with high activity, which can form hydrogen bonds inside or between molecules, and has good water solubility. It has s...
