[0034] Embodiment 2 Contrast test of special fertilizer of the present invention

[0035] The test site is located in the Jinjiang tea base in Tongren, Guizhou. The soil of the tea garden is flat, the geological nutrient structure is consistent, and the available potassium content in the soil is 63.54mg kg -1 . Test tealeaves kind is local black tea, and test establishes 2 processes, and control group area is 3 mus, uses the potash fertilizer that Jinan Linsheng Chemical Co., Ltd. produces, and consumption is 230kg / mu; Test group 3 mus, uses slow-release potash fertilizer of the present invention, The usage rate is 230kg / mu. On November 3, 2012, fertilization was applied to the two treatment groups respectively. The method of fertilization was point application, and one application was enough. Other water and fertilizer management measures were the same. The tea leaves were picked in June 2013, the yield of the tea leaves was calculated, and the content of aroma components ...

Abstract

The invention discloses sustained-release potassium fertilizer special for a tea tree, and a preparation method thereof, and relates to fertilizer, in particular to sustained-release potassium fertilizer. The sustained-release potassium fertilizer is prepared from sickle alfalfa, garlic straws, selenium dioxide, pine needle powder, earthworm excrement, potassium chloride, nano-carbon, nano-grade potassium feldspar, nano-grade kaolin, nano-grade montmorillonite, cellulase, lactic acid bacteria, saccharomyces cerevisiae, carboxymethylcellulose, rosin and soyabean lecithin by the steps of fermenting, pelleting and coating. The sustained-release fertilizer is rich in mineral substance, high in organic matter content, stable in fertilizer effect and not liable to lose, can increase the yield oftea and can increase the fragrance substance content of the tea.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a potash fertilizer, in particular to a special slow-release potash fertilizer for tea trees, and to a preparation method of the fertilizer. Background technique [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 the world's people's understanding of tea and the development of my country's export trade, my country's tea production will further develop. [0003] Tea trees, t...
