Anti-caking degradation type environmental-protection controlled-release fertilizer

Abstract

The present invention discloses an anti-caking degradation type environmental-protection controlled-release fertilizer, which is characterized by comprising, by weight, 30-40 parts of fermentation waste residue, 7 parts of urea ammonium polyphosphate, 3-5 parts of calcium ammonium nitrate, 3-5 parts of calcium hydrogen phosphate, 4-6 parts of potassium chloride, 10-15 parts of sodium sulfate powder, 5-10 parts of stone powder, 3-4 parts of animal and vegetable oil, 2-3 parts of C12-C20 alkyl sulfonate, 2-3 parts of C14-C20 fatty acid zinc Zn(RCOO)2, 10-20 parts of diatomaceous earth, 10-15 parts of humus, and 2-3 parts of microorganism flora. According to the present invention, with the fertilizer prepared by adopting the fermentation waste residue, the fertilizer and the diatom according to a certain ratio, the release speed of the degradation type controlled-release fertilizer is changed, the anti-caking property is good, the loose degree achieves 98%, the plant growth can be promoted, the growth of various pathogenic bacteria in the soil can be inhibited, the growth of various types of threadworms or soft insects in the soil can be inhibited, and the anti-caking degradation type environmental-protection controlled-release fertilizer is a environment-friendly pollution-free controlled-release fertilizer.

Description

technical field [0001] The invention relates to the technical field of fertilizer processing, in particular to an anti-caking and degradation-type environmental-friendly controlled-release chemical fertilizer. Background technique [0002] Chemical fertilizer plays an important role in agricultural production, and is the largest material investment in agricultural production, accounting for about 50% of its total productive expenditure. With the development of high-yield, high-efficiency and high-quality agriculture, the status of chemical fertilizer in my country's agriculture will become more and more important. [0003] However, due to losses such as volatilization and leaching, the seasonal utilization rate of my country's chemical fertilizers is very low. Once the concept of controlled-release chemical fertilizers is put forward, it has the function of matching plant physiology and growth patterns, so that it can be released to the surrounding environment at a predeterm...

Problems solved by technology

[0004] Chemical fertilizers are easy to absorb moisture in the air, and are easy to agglomerate during production and storage. The appearance and quality of chemical fertilizers are affected to a certain extent after agglomeration, and at the same time bring a lot of inconvenience to handling and use. It is necessary to smash the agglomerated fertilizer with hard things to facilitate the absorption of nutrients in the fertilizer. It is very inconvenient to use such fertilizer, and it takes time to break the agglomerated fertilizer, which is time-consuming and labor-intensive. And it is difficult to achieve the effect before no agglomeration

[0005] Although the effect of imported anti-caking agents is better, the price is relatively high, which increases the cost of the product; the anti-caking effect of domestic anti-caking agents is not very good, and the price is relatively cheap. Can not meet the requirements of production

[0006] As we all know, both chemical fertilizers and pesticides will pollute the environment, and long-term use of chemical fertilizers will also cause soil compaction, and the existing chemical fertilizers only have the function of fertilizers, not pesticides, so the use of existing chemical fertilizers At the same time, pesticides must be used at the same time. These chemical fertilizers and pesticides have caused double pollution to surface water and groundwater. After humans drink the polluted water quality that they depend on for survival, they greatly increase people's cancer and respiratory diseases. The probability of disease reduces the quality of human life and leaves serious troubles for future generations
