Efficient compound fertilizer and preparation method thereof

Abstract

The invention discloses an efficient compound fertilizer and a preparation method thereof. The efficient compound fertilizer is prepared from the following raw materials in parts by weight: 10-20 parts of bone meal, 5-10 parts of sodium molybdate dihydrate, 5-10 parts of monoammonium phosphate, 5-10 parts of ground phosphate rock, 3-5 parts of sodium hydrogen phosphate, 10-20 parts of straws, 3-5 parts of ferrous sulfate, 3-5 parts of potassium sulfate, 5-10 parts of humic acid, 10-20 parts of plant ash, 10-20 parts of cow dung, 5-10 parts of calcium superphosphate, 3-5 parts of ammonium chloride, 10-20 parts of urea, 3-5 parts of weathered coal, 4-6 parts of a potassium mineral powder, 4-6 parts of ethylene diamine tetraacetic acid, 4-6 parts of a rice hull powder and 4-6 parts of a mixed culture powder. The efficient compound fertilizer can not only promote growth of soybeans but also effectively inhibit soybean root rots, is obviously superior to a conventional compound fertilizer, and has prominent substantive features and remarkable advancement.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a high-efficiency compound fertilizer and a preparation method thereof. Background technique [0002] Organic fertilizers are rich in organic matter and a variety of nutrients, but the fertilizer efficiency is poor during use, and the short-term effect is not obvious, and most of the organic fertilizers use human and animal manure, garbage, and crop residues as traditional organic fertilizers, so it is difficult to supplement the elements required by the soil in a targeted manner . [0003] With the development and popularization of scientific farming technology, farmers have higher and higher requirements for the quality of chemical fertilizers. Simple chemical fertilizers are no longer suitable for scientific farming needs. Most of the compound fertilizers currently used are compound fertilizers such as ammonium bicarbonate and ammonium nitrate. After practice It has bee...

[0002] Organic fertilizers are rich in organic matter and a variety of nutrients, but the fertilizer efficiency is poor during use, and the short-term effect is not obvious, and most of the organic fertilizers use human and animal manure, garbage, and crop residues as traditional organic fertilizers, so it is difficult to supplement the elements required by the soil in a targeted manner

[0003] With the development and popularization of scientific farming technology, farmers have higher and higher requirements for the quality of chemical fertilizers. Simple chemical fertilizers are no longer suitable for scientific farming needs. Most of the compound fertilizers currently used are compound fertilizers such as ammonium bicarbonate and ammonium nitrate. After practice It has been proved that the single application of these waste materials is far from meeting the needs of farmland soil for nitrogen, phosphorus and potassium, and some soil quality is not suitable for these compound fertilizers. Long-term application will cause soil hardening and result in reduced production.
