An improved novel fertilizer and a preparation method thereof

Abstract

The invention discloses an improved novel fertilizer and a preparation method thereof. The fertilizer is prepared from following raw materials in parts by weight: 40-50 of decomposed farmyard manure, 25-30 of straw scraps, 15-20 of urea, 10-15 of alginic acid, 11-14 of boric acid, 5-10 of acrylic acid, 5-8 of polyacrylamide, 15-20 of sodium sulfate, 10-15 of zinc sulfate, 2-5 of cobaltous sulfate, 4-9 of potassium chloride, 3-8 of glycol, 11-14 of copper sulfate, 10-13 of sodium molybdate, 5-10 of manganese sulfate, 1-2 of an EM microbial inoculum and 7-11 of a soil modifier. The decomposed farmyard manure, the straw scraps, and other raw materials are adopted by the fertilizer. The raw materials are convenient to take, low in cost and comprehensive in nutrition, and can improve the soil structure. The urea, the alginic acid, the boric acid, the acrylic acid, and other chemical raw materials are added for supplementation, thus fully utilizing resources, reducing the production investment, and reducing pollution caused by chemical fertilizers. The added alginic acid not only contains a large quantity of organic materials, more than forty mineral elements such as potassium, calcium, magnesium, iron, etc. and rich vitamins, but also contains algal polysaccharides, highly unsaturated fatty acids and a plurality of natural plant growth regulators, and has high biological activity.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an improved new fertilizer and a preparation method thereof. Background technique [0002] my country is a big agricultural country, and it is also a big country that uses fertilizers. According to the statistics of my country's Ministry of Agriculture, the annual use of chemical fertilizers in my country accounts for 35% of the world's total. However, the utilization rate of fertilizer in our country is much lower than that in developed countries, and a large amount of fertilizer remains on the ground, which not only causes a serious decline in soil quality, but also pollutes water bodies, posing a threat to the sustainable development of my country's agriculture and the living environment of human beings. Therefore, it is imperative to develop new types of fertilizers and optimize the structure of fertilizers. The improved new fertilizer of the present invention adopts ra...
