Abstract

The invention discloses a high-utilization rice special fertilizer. The high-utilization rice special fertilizer comprises the following raw materials, by weight, 125-135 parts of macro-element fertilizer, 2-6 parts of composite coating agent, 4-12 parts of kainite, 45-55 parts of soil improvement agent, 1-5 parts of margarya melanoide, 1-5 parts of wollastonite powder, 1- 2 parts of zinc borate,0.1-0.2 part of iron humate, 0.1-0.2 part of zinc humate, 0.1-0.2 part of manganese humate, 0.1-0.2 part of brassinolide and 1- 4 parts of sepiolite powder. The composite coating agent is prepared bythe following process of evenly mixing a collagen solution and a keratin solution, adjusting the system pH to 6-6.4, raising the temperature and stirring, further adding glutamine transferase, continuing stirring, performing inactivation, adding glycerin and hydroxypropyl cellulose and evenly stirring to obtain the composite coating agent.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for rice with high utilization rate. Background technique [0002] Rice is one of the most important food crops in the world, and nearly half of the world's population uses rice as a staple food. my country is a big rice planting country, and the planting area is basically maintained at about 420-450 million mu. In the current production, farmers prepare their own nutrient soil, apply nitrogen fertilizer in rice production, and do not pay attention to the reasonable combination of phosphorus and potassium fertilizers, which leads to the inability to fully develop the rice yield potential, resulting in low fertilizer utilization rate, increased fertilization costs, and reduced rice planting benefits for rice farmers. . Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention propose...
