Problems solved by technology

[0003] At present, the fertilizers used for tea trees are mainly ordinary compound fertilizers and ordinary organic fertilizers. A small amount of special compound fertilizers for tea trees are mainly inorganic fertilizers. This kind of fertilizer dissolves quickly and has a short fertilizer effect. It needs frequent application to meet the absorption of tea trees.

Embodiment 1

[0042] In parts by mass, 50 parts of furfural slag, 30 parts of smoke residue, 19 parts of weathered coal and 1 part of microbial fermentation agent are fully mixed and uniform. Adjust the moisture content of the mixture to be 60%, C / N to be 25, and pH to be 7.5. Pile the mixture into a trapezoidal pile with a height of 1.5 meters, punch holes from the top down, 8 holes per square meter, cover with a plastic film, and carry out aerobic fermentation. When the temperature of the heap rises above 50°C, start timing, and ferment for 4 days. Turn over the pile, and ferment for another 3 days when the pile temperature rises above 50°C. Dry the moisture content of the above-mentioned fermented organic fertilizer to 30% for subsequent use. Take 55 parts of fermented organic fertilizer, 6 parts of urea, 12 parts of ammonium sulfate, 20 parts of diammonium phosphate, and 7 parts of potassium sulfate. Mix all raw materials evenly, and granulate with a disc granulator to obtain the pro...

Embodiment 2

[0044] In parts by mass, 60 parts of furfural slag, 25 parts of smoke residue, 13 parts of weathered coal and 2 parts of microbial fermentation agent are fully mixed and uniform. Adjust the moisture content of the mixture to be 65%, C / N to be 28, and pH7. Pile the mixture into a trapezoidal pile with a height of 2.0 meters, punch holes from the top down, 12 holes per square meter, cover with a plastic film, and carry out aerobic fermentation. When the temperature of the heap rises above 50°C, start timing, and ferment for 5 days. Turn over the pile, and ferment for another 2 days when the pile temperature rises above 50°C. Dry the moisture content of the above-mentioned fermented organic fertilizer to 25% for subsequent use. Take 65 parts of fermented organic fertilizer, 3 parts of urea, 10 parts of ammonium sulfate, 15 parts of diammonium phosphate, and 7 parts of potassium sulfate. Mix all raw materials evenly, and granulate with a disc granulator to obtain the product. ...

Embodiment 3

[0046] The preparation steps and method are the same as in Example 1, and the organic fertilizer fermentation raw materials are 50 parts of furfural residue, 30 parts of soot residue, 19 parts of weathered coal, and 1 part of microbial fermentation agent. After the fermentation, take 50 parts of fermented organic fertilizer, 10 parts of urea, 22 parts of ammonium sulfate, 8 parts of diammonium phosphate, and 10 parts of potassium sulfate, mix them evenly, and granulate with a disc granulator to obtain the product. This fertilizer is suitable for tea tree adult trees.

Abstract

The invention relates to an organic and inorganic compound fertilizer specially used for tea trees and a preparation method thereof. The organic and inorganic compound fertilizer is prepared from the following raw materials by weight portion: 40-70 portions of fermented organic fertilizer, 3-15 portions of carbamide, 10-30 portions of ammonium sulfate, 5-25 portions of diammonium phosphate and 5-15 portions of potassium sulphate, wherein the fermented organic fertilizer is prepared by taking 45-65 portions of furfural residues, 20-35 portions of fuming slag and 10-20 portions of weathered coal as raw materials and adding 1-2 portions of microbial fermentation agent EM compound microbial agents to be accumulated and fermented and then dried until the moisture content is 25-35 percent. The organic and inorganic compound fertilizer specially used for the tea trees has long-time fertilizer effect, thereby increasing the fertilizing times; and in addition, the organic and inorganic compound fertilizer specially used for the tea trees has reasonable nutrient proportion, thereby enhancing the tea-leaf yield.

Description

technical field [0001] The invention relates to a special organic-inorganic compound fertilizer for tea trees prepared by adding inorganic chemical fertilizers to fermented and decomposed organic fertilizers, belonging to the technical field of fertilizer production. Background technique [0002] The fertilization of tea gardens in various tea-producing countries in the world has experienced changes from organic fertilizers to inorganic fertilizers to a combination of organic and inorganic fertilizers. The quality of tea produced by pure application of organic fertilizer is good, but the yield is not high. Although the yield of tea produced by pure application of inorganic fertilizers has been greatly increased, the quality has declined. Organic-inorganic fertilizer combined application is the direction of tea tree fertilization. Compared with other crops, tea tree, as a leaf-picking plant, has a large demand for nitrogen during growth and development, and the absorption i...
