Problems solved by technology

At present, the fertilizers used for tea trees are mainly ordinary compound fertilizers and ordinary organic fertilizers, and a small amount of special fertilizers for tea trees are mainly inorganic fertilizers. This kind of fertilizer dissolves quickly and has a short fertilizer effect. Frequent application is required to meet the nutrients required for the growth and development of tea trees.

Embodiment 1

[0042] 50 parts of bagasse, 15 parts of rice hulls, 8 parts of rapeseed cake, and 1 part of microbial fermentation agent are fully mixed and evenly distributed. Adjust the water content of the mixture to 60%, C / N to 22, and pH 7.0. Pile the mixture into a trapezoidal pile with a height of 1.5 meters, punch holes from the top down, 10 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 3 days. Turn over the pile, and ferment for 3 days when the pile temperature rises above 50°C. Dry the moisture of the above-mentioned fermented organic fertilizer to 25% for subsequent use. Take 45 parts of fermented organic fertilizer, 5 parts of urea, 10 parts of ammonium sulfate, 25 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 2

[0044] 65 parts of bagasse, 30 parts of rice husks, 20 parts of rapeseed cake, and 2 parts of microbial fermentation agent are fully mixed and uniform. Adjust the moisture of the mixture to be 70%, C / N to be 28, and pH6.5. Pile the mixture into a trapezoidal pile with a height of 2.0 meters, punch holes from the top down, 15 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 4 days when the pile temperature rises above 50°C. Dry the moisture of the above-mentioned fermented organic fertilizer to 10% for subsequent use. Take 70 parts of fermented organic fertilizer, 15 parts of urea, 25 parts of ammonium sulfate, 8 parts of diammonium phosphate, and 16 parts of potassium sulfate. Mix all raw materials evenly, and granulate with a disc granulator to obtain the product.

Embodiment 3

[0046] 55 parts of bagasse, 25 parts of rice husks, 15 parts of rapeseed cake, and 1 part of microbial fermentation agent are fully mixed and evenly distributed. Adjust the water content of the mixture to 60%, C / N to 24, and pH 7.0. Pile the mixture into a trapezoidal pile with a height of 1.5 meters, punch holes from the top down, 10 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 3 days when the pile temperature rises above 50°C. Dry the moisture of the above-mentioned fermented organic fertilizer to 20% 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 product. This fertilizer is suitable for young t...

Abstract

The invention belongs to the technical field of fertilizer production and relates to a special organic / inorganic compound fertilizer for tea trees and a preparation method of the special organic / inorganic compound fertilizer. The special organic / inorganic compound fertilizer is prepared from the following raw materials in parts by mass: 45-70 parts of an organic fermented fertilizer, 5-15 parts of urea, 10-25 parts of ammonium sulfate, 8-25 parts of diammonium phosphate and 7-16 parts of potassium sulfate, wherein the organic fermented fertilizer is prepared through the steps of with 50-65 parts of bagasse, 15-30 parts of rice husks and 8-20 parts of rapeseed cakes as raw materials, adding 1-2 parts of a microbial fermentation bactericide, namely EM complex bactericide, stacking, fermenting, and airing until the water content is up to 10-25%. By using the special organic / inorganic compound fertilizer for tea trees, disclosed by the invention, the fertilizer efficiency time is long, the fertilization times can be reduced, the nutrient ratio is reasonable, the improvement of soil fertility can be promoted, the quality of tea can be improved, and the yield of tea can be increased.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and relates to a special organic-inorganic compound fertilizer for tea trees prepared by adding inorganic fertilizers to fermented and decomposed organic fertilizers. Background technique [0002] The types of fertilizers used in tea gardens have undergone 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 compound fertilizers can take into account both tea quality and yield. The combined application of organic-inorganic fertilizers is the direction of tea fertilization. Compared with other crops, tea tree, as a leaf-picking plant, has a large demand for nitrogen duri...
