Special fertilizer for fruit trees and preparation method thereof

Abstract

The invention discloses a special fertilizer for fruit trees, which is prepared from the following raw materials in parts by weight: 50-55 parts of peat soil, 20-23 parts of vermiculite, 30-34 parts of urea, 18-19 parts of potassium oxide, 8-10 parts of potassium sulfate, 2-3 parts of zinc sulfate, 1-2 parts of manganese sulfate, 1-2 parts of magnesium sulfate, 2-3 parts of boric acid, 1-2 parts of ferrous sulfate, 1-2 parts of magnesium oxide, 1-2 parts of aluminosilicate, 2-5 parts of synergistic sodium, 2-3 parts of dicyandiamide, 3-4 parts of EM bactericide, 4-6 parts of coating agent and a proper amount of water. The fertilizer disclosed by the invention is scientific and reasonable in proportion; based on the growth rules of the fruit trees, the fertilizer has a function of improving the quality and output of the fruit trees; meanwhile, the special fertilizer maintains water and fertilizer, realizes long duration of fertilizer efficiency and promotes the root growth. Moreover, the fertilizer also has a function of improving the soil to keep the soil in a loose and breathable state for a long time; since the organic ingredients of the fertilizer are added, the soil is rich in organic matters and is cured, and the fertility is improved.

Description

[0001] technical field [0002] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for fruit 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. Can'...

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
