Efficient compound fertilizer and preparation method thereof

Abstract

The invention discloses an efficient compound fertilizer which is prepared from the following raw materials in parts by weight: 70-80 parts of sheep manure, 45-50 parts of waste residues of beer, 23-26 parts of pear saw dust, 30-34 parts of potatoes, 30-34 parts of urea, 20-23 parts of monopotassium phosphate, 12-17 parts of diammonium phosphate, 10-14 parts of potassium chloride, 10-12 parts of potassium sulfate, 1-2 parts of sodium sulfite, 4-6 parts of sodium humate, 4-6 parts of a coating agent, 3-4 parts of an EM bactericide, and a proper amount of water. The fertilizer disclosed by the invention is prepared from organic matters including the sheep manure, the waste residues of beer, the pear saw dust, the potatoes and the like which are added with nitrogen, phosphorus and potassium, micro-elements, mid-elements and a sustained-release material, so that the fertility of the soil is improved and the aim of slowly releasing fertilizer nutrients is achieved, the utilization rate of the fertilizer is increased as well, and the environmental pollution is reduced. The prepared fertilizer has the characteristics of water retention, fertilizer retention, long fertilizer action time and good air permeability; meanwhile, the soil can be improved, nutrient balance of the soil is guaranteed, and sustainable development of the agriculture is promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-efficiency compound fertilizer and a preparation method thereof. Background technique [0002] From ancient times to the present, agriculture has played an important role in our country, and fertilizers play a decisive role in the growth of crops, so our country is also a big country in the use of fertilizers. At present, my country mainly uses chemical fertilizers, and the amount of chemical fertilizers used is also increasing, and the varieties used are mostly unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and the ability to retain water and fertilizer. Phenomena such as weakening not only waste fertilizers, but also increase the burden on farmers, and also have a certain impact on the environment. Our country has always advocated the rapid and sustain...

Problems solved by technology

At present, my country mainly uses chemical fertilizers, and the amount of chemical fertilizers used is also increasing, and the varieties used are mostly unit nitrogen fertilizers, while the use of multi-element fertilizers containing phosphorus and potassium elements is relatively small, resulting in soil hardening and the ability to retain water and fertilizer. Phenomena such as weakening, not only waste fertilizers, but also increase the burden on farmers, and also have a certain impact on the environment

Our country has always advocated the rapid and sustainable development of agriculture, but due to various reasons, the utilization rate of fertilizers in our country has been kept at a low level
