Embodiment 1

[0034] Special organic-inorganic compound fertilizer for young tea trees, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 12.2%, 8.7%, and 6.0% respectively; organic matter content and humic acid content are 30.6% and 16.9%, respectively, both Mass percent. The preparation method is as follows:

[0035] First, mix 200kg of weathered coal, 34.5kg of ammonium bicarbonate, 20kg of heavy calcium, and 150kg of 5% ammonia water evenly, seal with plastic cloth, mature at room temperature for 6 days, and dry to obtain ammonium humate.

[0036] Take 440kg of water in the reactor, heat it up to 55°C, add 220kg of weathered coal and 220kg of urea, stir to dissolve, raise the temperature to 95°C, add 20g of diammonium phosphate, continue to react for 1.5 hours, and dry to obtain humic acid urea.

[0037] Mix 450kg of crushed humic acid urea, 100g of ammonium humate, 160g of monoammonium phosphate, 120g of potassium sulfate, 6kg of manganese sulfate, 6kg of zi...

Embodiment 2

[0039] Special organic-inorganic compound fertilizer for young tea trees, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 8.9%, 4.2%, and 3.1% respectively; organic matter content and humic acid content are 36.8% and 19.7%, respectively, all are percentages by mass .The preparation method is as follows:

[0040] First prepare ammonium humate according to the method in Example 1. Then mix 400kg of crushed ammonium humate, 300kg of ammonium sulfate, 78kg of monoammonium phosphate, 60kg of potassium sulfate, 8kg of magnesium sulfate, 8kg of aluminum sulfate, 8kg of manganese sulfate, 8kg of zinc sulfate, 8kg of borax, and 122kg of bentonite. Use water as a binder to granulate, dry, cool and sieve after granulation to obtain organic-inorganic compound fertilizer for young tea leaves.

Embodiment 3

[0042]Special organic-inorganic compound fertilizer for young tea trees, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 17.4%, 6.1%, and 10.3% respectively; organic matter content and humic acid content are 20.8% and 12.4%, respectively, all in mass percentage .The preparation method is as follows:

[0043] First prepare humic acid urea according to the method in Example 1. Then 550kg of crushed humic acid urea, 104g of monoammonium phosphate, 200g of potassium sulfate, 10kg of manganese sulfate, 20kg of aluminum sulfate, 10kg of zinc sulfate, 10kg of borax, and 96kg of calcium magnesium phosphate fertilizer were mixed evenly. Use water as a binder to granulate, dry after granulation, cool and sieve to obtain organic-inorganic compound fertilizer for young tea leaves.

Abstract

The invention provides a special organic-inorganic compound fertilizer for young tea trees and a preparation method thereof. The compound fertilizer is composed of the following components in parts by weight: 0-60 parts of humic acid urea, 0-40 parts of ammonium humate, 0-30 parts of ammonium sulfate, 5-16 parts of monoammonium phosphate, 6-20 parts of potassium sulfate, 2-5 parts of secondary and minor element and 5-20 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 and smelliness 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 fertilizers, in particular to special organic-inorganic compound fertilizers for young tea trees and a preparation method. Background technique [0002] Tea tree is a perennial economic crop for the purpose of harvesting young shoots and leaves. It is necessary to pick new green and nutritious young shoots from tea trees many times a year, which greatly consumes the nutrition of tea trees. Tea trees with different developmental cycles have different requirements for mineral nutrition due to the obvious differences in the response of their physiological functions to environmental conditions. Young tea trees are vigorous, fast-growing, and vegetative growth dominates. The nutrients absorbed from the soil are mainly consumed in the growth of roots, stems, leaves and buds. The purpose of young tea tree cultivation is to cultivate a huge root system and a strong skeleton. branches, the demand ratio of phosphorus and potassium is re...
