Composite fertilizer used for tea trees and capable of improving soil structure

Abstract

The invention discloses a composite fertilizer used for tea trees and capable of improving soil structure. The composite fertilizer comprises the following raw materials by weight: 20 to 35 parts of urea, 15 to 35 parts of monoammonium phosphate, 4 to 16 parts of double superphosphate, 10 to 20 parts of potassium dihydrogen phosphate, 2 to 8 parts of magnesium-potassium sulfate fertilizer, 2.5 to 4.5 parts of trace elements, 30 to 40 parts of a slow release system, 2 to 6 parts of gelatin, 20 to 30 parts of fermented cottonseed meal, 5 to 15 parts of peat soil, 4 to 18 parts of peanut shell powder, 5 to 15 parts of corn cob powder, 30 to 60 parts of peanut meal and 4 to 12 parts of buckwheat flour. The composite fertilizer provided by the invention realizes reasonable compounding of all the nutrient elements needed in the growth of the tea tree, and has excellent water retention, fertilizer preservation and slow release performance; after the composite fertilizer is applied to soil, available nutrients in the composite fertilizer are slowly released to prolong the duration of fertilizer efficiency; harm to soil caused by inorganic fertilizer components in the composite fertilizer is reduced, and soil hardening is avoided; and the composite fertilizer can improve the physical and chemical properties and fertility of soil.
