Embodiment 1

[0027] Humic acid slow-release fertilizer for double-living and double-effect tea trees, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 18%, 13%, and 12% respectively; humic acid, sulfur, and aluminum are 3.6%, 5.0% and 2.1%, both are mass percentages. The raw material components are as follows:

[0028]

[0029] The preparation method is that the above-mentioned raw materials are put into a blender and stirred for 5-10 minutes, and fully mixed to obtain the product. Then the mixed fertilizer is sent to the metering and packaging machine for metering and packaging.

Abstract

The invention relates to a formula and a preparation method of a special double-activity double-effect humic acid slow release fertilizer for tea tree. The special double-activity double-effect humic acid slow release fertilizer is compounded from a humic acid long-acting nitrogen fertilizer, large granule urea, monoammonium phosphate, diammonium phosphate, granular potassium sulfate, borax and the like. The special double-activity double-effect humic acid slow release fertilizer for tea tree is applied at one time before the tea tree sprouts in early spring, can reduce the damage on the root system due to many times of fertilizer application, saves both time and labor, can satisfy the demands of the tea tree for nutrients in the whole growth period, enhances the utilization ratio of the fertilizer and keeps soil from packing together.

Description

1: Technical field [0001] The present invention relates to the formulation and preparation method of special humic acid slow-release fertilizer for double-active double-effect tea trees, and is a new fertilizer for active humic acid and long-acting nitrogen fertilizer of active humic acid and nitrogen by using weathered coal or lignite as raw material crafting techniques. Two: background technology [0002] Tea trees are native to the Yunnan-Guizhou Plateau. my country is the first country in the world to discover and utilize tea trees. As of 2010, the area of ​​my country's tea gardens and tea output have grown steadily, with a total area of ​​2 million hectares, ranking first in the world; the annual output of tea is 1.43 million tons, ranking first in the world. Tea has also become one of my country's important export agricultural products. In 2010, my country exported 308,000 tons of tea, and the export value exceeded US$700 million. With the continuous deepening of th...
