Multifunctional biological organic composite coated fertilizer and preparation method thereof

Abstract

The invention discloses multifunctional biological organic composite coated fertilizer. The multifunctional biological organic composite coated fertilizer is prepared from 65-69 parts by weight of rye bran, 56-59 parts by weight of rice saccharified slag, 35-40 parts by weight of mix-fired soya bean powder, 15-19 parts by weight of potassium chloride, 29-33 parts by weight of urea, 3-5 parts by weight of alum, 1-2 parts by weight of citric acid, 2-4 parts by weight of aluminum sulfate, 8-10 parts by weight of bamboo carbon powder, 2-3 parts by weight of starch ether, 2-4 parts by weight of fructus quisqualis powder, 22-25 parts by weight of diammonium phosphate, 5-7 parts by weight of an EM microbial inoculum, 3-4 parts by weight of neem bark powder, 7-9 parts by weight of a soil conditioner and a proper amount of water. The multifunctional biological organic composite coated fertilizer has a reasonable formula. Through use of the soil conditioner, effects of improving fertilizer effects and promoting nutrient absorption of plants are obtained. Through use of raw materials such as fructus quisqualis powder and neem bark powder, effects of expelling insects, killing insects, preventing insects, reducing or avoiding pesticide use and protecting the environment are obtained. Through use of the urea coating, the multifunctional biological organic composite coated fertilizer has slow release effects, prolongs fertilizer action time and realizes yield increasing.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a multifunctional bio-organic composite coated fertilizer and a preparation method thereof. Background technique [0002] Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances. Film-forming substances include plastics, resins, paraffin, polyethylene and elemental sulfur. The purpose of the coating is to slowly release the quick-acting nutrients in the coated fertilizer after it is applied to the soil, so as to prolong the fertilizer effect. The release rate depends on the type of coating, thickness, particle size, fertilizer solubility, soil temperature, soil water content, and soil microbial activity. It is suitable for crops with high economic value, long growth period, large amount of fertilizer but inconvenient to fertilize in batches, and high te...

Problems solved by technology

In order to meet the needs of the development of agricultural modernization, the production of fertilizers is developing in the direction of diversification such as high-efficiency compound fertilizers and multi-functional fertilizers. The use of fertilizers with insecticidal and weeding effects can make the fertilization of crops and the prevention and control of diseases, insect pests and weeds more effective. One-time completion can save a lot of labor and improve efficiency, but if the fertilizer is not properly matched, it will not only reduce the fertility of the fertilizer and the efficacy of insecticide and weed control, but will even have more serious consequences
