preparation example Construction

[0041] According to another aspect of the present invention, the present invention also provides a method for preparing rice and corn slow-release synergistic compound fertilizer, comprising the steps of: mixing urea, thiamine, ammonium chloride, monoammonium phosphate, potassium chloride, Inorganic salts of trace elements, nano-carbon, water-retaining and controlled-release agents, long-acting compound fertilizer additives and microbial compound bacterial agents are evenly mixed, and the slow-release synergistic compound fertilizer for rice and corn is obtained through granulation.

[0042] The preparation method of the rice-corn slow-release synergistic compound fertilizer provided by the invention has simple process, convenient operation, saves a lot of manpower and material resources, can effectively improve the preparation efficiency of the rice-corn slow-release synergistic compound fertilizer, and reduces the preparation cost.

[0043] In a preferred embodiment of the pr...

Embodiment 1

[0047] This embodiment provides a slow-release synergistic compound fertilizer for rice and corn, which is prepared from the following raw materials in parts by mass: 310 parts of urea, 90 parts of thiamine, 300 parts of ammonium chloride, 110 parts of monoammonium phosphate, 174 parts of potassium, 1 part of medium and trace element inorganic salt, 2 parts of nano-carbon, 6 parts of water-retaining and controlled-release agent, 3 parts of long-acting compound fertilizer additive, 4 parts of microbial compound agent, of which water-retaining and controlled-release agent is γ-polygu Amino acid; the long-acting compound fertilizer additive is composed of hydroquinone, dihydroamine, complex rare earth and zeolite powder, and the mass ratio of hydroquinone, dihydroamine, complex rare earth and zeolite powder is 10:29:1:160 The medium and trace element inorganic salt is a mixture of medium and trace element inorganic salt, the medium element inorganic salt is a mixture of calcium ni...

Embodiment 2

[0049] This embodiment provides a slow-release and synergistic compound fertilizer for rice and corn, which is prepared from the following raw materials in parts by mass: 330 parts of urea, 110 parts of thiamine, 289 parts of ammonium chloride, 95 parts of monoammonium phosphate, 160 parts of potassium, 2 parts of medium and trace element inorganic salts, 1 part of nano-carbon, 6 parts of water-retaining and controlled-release agent, 2 parts of long-acting compound fertilizer additive, 5 parts of microbial compound bacterial agent, of which water-retaining and controlled-release agent is cross-linked γ- Polyglutamic acid, cross-linked γ-polyglutamic acid is cross-linked by γ-polyglutamic acid and activated diatomaceous earth under the action of carbodiimide or hydroxysuccinimide, γ-polyglutamic acid The mass ratio with active diatomaceous earth is 1:2, and the molecular weight of gamma-polyglutamic acid is 10-200 ten thousand Da; The difference is that the mass ratio of medium...

Abstract

The invention provides a rice and corn sustained-release synergic compound fertilizer and a preparation method thereof and relates to the technical field of fertilizers. The rice and corn sustained-release synergic compound fertilizer is prepared from the following raw materials in parts by mass: 310-330 parts of urea, 90-110 parts of thiamine, 9-5-110 parts of monoammonium phosphate, 160-180 parts of potassium chloride, 1-2 parts of medium trace element inorganic salt, 1-2 parts of nanocarbon, 4-6 parts of a water retaining sustained-release agent, 2-4 parts of a long-acting compound additive and 4-6 parts of a microbial compound inoculant. The fertilizer alleviates the technical problems that the soil structure is damaged, the water body is polluted, the utilization ratio of the fertilizer is reduced and the quality of agricultural products is decreased as an existing chemical fertilizer is applied for a long time. The fertilizer not only provides rich nutritional elements, such as nitrogen, phosphorus and potassium, for crops, but also provides medium trace elements for the crops, and meanwhile, the fertilizer efficiency is as long as more than 120 days, so that the soil environment is improved and the quality and output of the agricultural products are enhanced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a slow-release and synergistic compound fertilizer for rice and corn and a preparation method thereof. Background technique [0002] Chemical fertilizers, mainly containing nitrogen, phosphorus, and potassium elements, are used to supplement the lost nutrients for the soil, thereby increasing crop yields. However, long-term application of chemical fertilizers has brought about soil structure damage, water pollution, reduced fertilizer utilization efficiency, and reduced quality of agricultural products, etc. serious negative issue. At present, our food safety situation is still severe, and the source pollution of agricultural products ranks first. Soil is a nutrient supplier and a nutrient storage agent. Improving soil, nourishing soil, and restoring soil vitality are important factors for food safety, human civilization and science. The only way to develop. [0003] Howeve...
