preparation example Construction

[0029] A preparation method of a novel fertilizer synergist, comprising the following steps:

[0030] S1: mix the microbial agent evenly according to the parts by weight, and set aside;

[0031] S2: Add urease inhibitor, nitrification inhibitor, bioactivating enzyme, water-retaining agent and the microbial agent prepared in step S1 to 35-100ml of water according to parts by weight and stir to obtain a synergist mixture;

[0032] S3: pass the synergist mixture obtained in step S2 through a 10-30 mesh sieve, and dry to obtain a novel fertilizer synergist.

[0033] Technical principle of the present invention: the urease inhibitor itself is a reducing agent, which can change the redox conditions of the micro-ecological environment in the soil, reduce the activity of soil urease, reduce the water solubility of urea, and slow down the hydrolysis rate of urea; hexamethylphosphoryl Triamine has strong hygroscopicity, has certain biological activity and antibacterial effect; copper s...

Abstract

The invention discloses a novel fertilizer synergist and a preparation method thereof, and belongs to the technical field of fertilizer preparation. The novel fertilizer synergist comprises a urease inhibitor, a nitrification inhibitor, a composite biological agent and a water-retaining agent. The synergist can reduce the loss of effective components in a fertilizer, increase the utilization rateof the fertilizer, improve the soil environment and improve the crop quality.

Description

technical field [0001] The invention relates to the field of fertilizer processing, in particular to a novel fertilizer synergist and a preparation method thereof. Background technique [0002] Fertilizer is an indispensable means of production in agricultural production and is the "grain" of food. Therefore, since the founding of the People's Republic of China, in order to solve the problem of food production and make the people have enough to eat, our country has actively promoted the development of the chemical fertilizer industry. By introducing foreign fertilizer production enterprises and learning their advanced production technology, a group of enterprises with advanced production technology and management capabilities have been created. The state-owned, public-private joint ventures, and private fertilizer enterprises have played a huge role in promoting the development of my country's fertilizer industry. The healthy development of the fertilizer industry is the bas...
