Problems solved by technology

However, the active ingredients in organic fertilizers are low and the release is slow, which cannot meet the requirements of large fertilizer demand and fast absorption of tea trees in the growing season. It must be combined with quick-acting chemical fertilizers with high effective concentrations. Only in this way can both soil improvement and fertility be achieved. The purpose, but also to meet the requirements of tea tree fertilizer absorption

Abstract

The invention discloses a special organic-inorganic compound fertilizer for mature tea trees and a preparation method thereof. The compound fertilizer is composed of the following components in parts by weight: 20-35 parts of ammonium humate, 35-50 parts of ammonium sulfate, 5-10 parts of monoammonium phosphate, 6-20 parts of potassium sulfate, 1-3 parts of secondary and minor element and 5-10 parts of additive. The preparation method comprises the following steps: respectively pulverizing the components, mixing, granulating, drying, cooling and screening to obtain the product. The fertilizer is developed according to the tea nutrient absorption characteristics, implements organic combination of the soil conditioner, secondary and minor elements and quick-acting inorganic fertilizer, integrates the advantages of stable and long fertilizer efficiency in the organic fertilizer and the advantages of high speed and high efficiency in the chemical fertilizer, can be conveniently and cleanly applied to a tea garden, and can improve the tea quality, enhance the tea yield and improve the soil. The compound fertilizer overcomes the defects of time and labor consuming, dirtiness, smelliness and the like in the farm manure, obviously reduces the amount of application of the chemical fertilizer, enhances the utilization ratio of the fertilizer and lowers the labor cost.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organic-inorganic compound fertilizer for mature tea trees and a preparation method thereof. Background technique [0002] Tea is an important economic crop in my country and an important agricultural product for people's consumption and export. In 2010, the total area of ​​tea gardens in my country reached 2 million hectares, ranking first in the world. The mineral elements necessary for the growth and development of tea trees include macroelements such as nitrogen, phosphorus, potassium, calcium, iron, magnesium, and sulfur, and trace elements such as manganese, zinc, copper, boron, molybdenum, aluminum, and fluorine. The absorption ratio of nitrogen, phosphorus and potassium for mature tea trees is 1:0.16-0.35:0.33-0.58. The growth and development of mature tea trees are relatively stable, and the absorption of nutrients is also relatively stable. During this period, the mineral nutrients ...
