Biological fertilizer special for flowers and preparation method thereof

Abstract

The invention discloses a biological fertilizer special for flowers. The biological fertilizer special for flowers comprises the following materials in parts by weight: 30-40 parts of chicken manure, 15-20 parts of peat soil, 12-15 parts of rice chaff, 10-13 parts of wheat bran, 8-15 parts of fallen leaves, 20-30 parts of mushroom residue, 12-15 parts of feather, 10-16 parts of straw, 12-17 parts of monoammonium phosphate, 15-25 parts of urea, 10-15 parts of potassium sulphate, 12-15 parts of ammonium sulfate, 11-12 parts of ammonium bicarbonate, 6-8 parts of carboxymethyl chitosan, 4-6 parts of azadirachtin, 2-4 parts of zinc sulfate, 4-6 parts of ferrous sulfate, 1.1-1.3 parts of borax, 25-28 parts of potassium fulvic acid and 0.5-0.8 part of microorganism yeast. The invention also discloses a preparation method of the biological fertilizer. The biological fertilizer special for flowers has the advantages that the ecological environment and farmland soil can be protected, nitrogen, phosphorus and potassium are blended scientifically, crops are easy to absorb, the production increasing is obvious, double functions of fertilizing and killing insects are realized, and environmental protection is achieved.

Description

technical field

[0001] The invention relates to a fertilizer for flowers, in particular to a special biomedical fertilizer for flowers and a preparation method thereof. Background technique

[0002] With the continuous development of science and technology, conventional chemical fertilizers and pesticides have emerged as the times require. Farmers use them in large quantities year after year, causing a sharp decrease in the beneficial bacteria in the soil and a serious lack of organic nutrients, resulting in a large number of pests and diseases, increased pesticide residues, and soil Nutrients (N, P, K) were lost seriously. However, the existing biological pesticides and botanical pesticides all have poor broad-spectrum properties, slow insecticidal effects, and high prices, which are difficult for farmers to accept.

[0003] In addition, a good disposal of domestic waste is one of the keys to environmental protection. The current state of social development is that with t...
