Abstract

The invention discloses a fertilizer synergist for improving the phosphorus absorptive amount of oilseed rape, wherein the fertilizer synergist is prepared from the following raw materials in parts by weight: 36-39 parts of kaolin, 6-7 parts of a calcium carbonate powder, 3-4 parts of attapulgite clay, 60-80 parts of modified ground phosphate rock, 1-2 parts of a compound sodium nitrophenolate preparation, 3-6 parts of sodium humate, 8-10 parts of vinasse, 12-14 parts of dead leaves, and a proper amount of water. The modified ground phosphate rock utilized in the fertilizer synergist is low in price, and after the ground phosphate rock is activated by gamma-polyglutamic acid, not only is the absorption of oilseed rape on phosphorus facilitated, but also the utilization rate of a phosphate fertilizer can be improved, a soil phosphorus deficiency problem can be effectively relieved, and at the same time, with the use of a large number of ground phosphate rock in the synergist, a great promoting role is provided in development of middle-low grade phosphate ore resources in China.

Description

technical field [0001] The invention relates to the technical field of fertilizer synergists, in particular to a fertilizer synergist agent for improving phosphorus absorption of rapeseed 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 solub...
