A novel farm-oriented fertilizer and a preparation method thereof

Abstract

The invention discloses a farm-oriented fertilizer. The fertilizer is prepared from following raw materials in parts by weight: 30-35 of biogas residue, 20-24 of bran, 12-15 of soybean meal, 10-13 of bone meal, 10-12 of lignite, 13-15 of medical stone, 10-13 of urea, 18-20 of potassium sulfate, 12-14 of potassium dihydrogen phosphate, 4-5 of ammonium molybdate, 4-6 of borax, 2-4 of humic acid and 9-12 of a soil conditioner. The biogas residue, the bran, the soybean meal, and other agricultural and sideline raw materials are adopted by the fertilizer. The agricultural and sideline raw materials are convenient to take, low in cost and rich in nutrition, and can improve the soil structure. The lignite and the medical stone, which have rich nutrition and multi functions and are natural raw materials, are added for supplement, thus fully utilizing resources, reducing the production investment and reducing pollution caused by chemical fertilizers. The added borax provides trace elements for plants, and the borax itself has a function of germ control. The biogas residue contains rich organic matters, humus, micronutrient elements, a plurality of amino acids, enzymes and beneficial microorganisms. The biogas residue has loose texture and a moderate acid-base value, and is capable of modifying the soil when the biogas residue is produced into fertilizers. In addition, the biogas residue is capable of reducing the using amount of chemical fertilizers and pesticides, reducing the cost and effectively improving the crop quality and the yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a novel agricultural 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 novel agricultural fertilizer of the present inventio...
