Special formulated fertilizer for pear trees and preparation method thereof

Abstract

The invention discloses a special formulated fertilizer for pear trees. The special formulated fertilizer is prepared from the following raw materials in parts by weight: 50-55 parts of cotton straw scraps, 20-23 parts of wheat bran, 20-23 parts of Chinese medicine residue, 12-14 parts of corn flour, 1-2 parts of tea leaf powder, 30-35 parts of urea, 12-15 parts of calcium-magnesium-phosphate fertilizer, 20-24 parts of potassium chloride, 2-3 parts of borax, 2-3 parts of ethyl cellulose, 1-2 parts of boric acid, 1-2 parts of stannous chloride, 3-4 parts of sodium hydrogen sulfite, 3-4 parts of EM fungicide, 4-6 parts of coating agent and a proper amount of water. The special fertilizer for fruit trees disclosed by the invention is mainly prepared from cotton straw scraps, wheat bran, Chinese medicine residue, corn flour and other domestic waste in a fermentation manner and then is combined with inorganic fertilizer, thereby not only saving resource and solving environmental pollution and other problems; the prepared fertilizer is rich in organic matters, thus enhancing fertility of soil and promoting growth and development of pear trees; and the special fertilizer also improves soil structure and increases utilization rate of pear trees to the fertilizer. The prepared fertilizer has excellent economic and environmental benefits.

Description

[0001] technical field [0002] The invention relates to the technical field of fertilizers, in particular to a special formula fertilizer for pear trees and a preparation method thereof. Background technique [0003] At present, my country's fertilizers are mainly chemical fertilizers composed of three inorganic elements, N, P, and K. This chemical fertilizer can meet the growth needs of crops in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, which will affect the growth of crops and the decline in quality, resulting in a vicious circle. At the same time, although the organic fertilizer is rich in organic matter, the release of nutrients is slow, resulting in slow absorption of crops, low fertilizer efficiency, and no effective balance between various effective nutrients. Due to the unscientific fertilizer formula for crops, the yield of crops is not high and the quality is also low...

At the same time, although the organic fertilizer is rich in organic matter, the release of nutrients is slow, resulting in slow absorption of crops, low fertilizer efficiency, and no effective balance between various effective nutrients. Due to the unscientific fertilizer formula for crops, the yield of crops is not high and the quality is also low. not improved
