Embodiment 1

[0078] Embodiment 1: The preparation technology of the special slow-release fertilizer for tea tree with biomass granular carbon as matrix

[0079] Follow the steps below to mix by weight ratio or weight percentage:

[0080] (1) Take large-grain urea with a nitrogen (N) content of 46%, and 80-mesh biomass granular carbon particles, mix them in a ratio of 70.9% and 29.1%, and use a disc granulator with a heating function (fertilizer Commonly used machinery in the preparation process) for coating to make an elemental slow-release nitrogen fertilizer with a nitrogen (N) content of 32.61%.

[0081] (2) Take ammonium sulfate with a nitrogen (N) content of 21.2%, 80-mesh biomass granular charcoal and a binder, mix them in proportions of 72.6%, 20.8% and 6.6%, and use KP-300 organic fertilizer to granulate Machine carries out pressure granulation, makes the slow-release nitrogen fertilizer that contains nitrogen (N) amount 15.39%.

[0082] (3) Take diammonium phosphate powder wi...

Abstract

The invention discloses a special slow-release fertilizer taking biomass granular carbon as a matrix for tea trees and a preparation method thereof. Granular carbon prepared from agricultural abandoned biomass such as corncobs, peanut shells, rice husks and edible mushroom matrixes, taken as a matrix material, is compounded with nitrogen, phosphorus, potassium and other nutrient elements essential to the growth and development of the tea trees by utilizing the microporous character and strong adsorption capacity of the granular carbon, so that the special slow-release fertilizer taking the biomass granular carbon as the matrix for the tea trees is prepared. According to the invention, the biomass granular carbon is black biomass granular carbon particles formed after incomplete combustion of the agricultural abandoned biomass under a hypoxic condition, has various properties similar to those of soil humus, is very strong in capacity of adsorbing and maintaining nutrients and moisture, and furthermore, and has an effect of stimulating the growth of crops and a good slow-release performance for the nitrogen, phosphorus and potassium; the slow-release fertilizer prepared in such a way can effectively meet the requirements of the tea trees for nutrients in the whole growth period after being applied once; and in addition, the special slow-release fertilizer has the characteristics of enhancing the soil fertility, improving the soil structure, being efficient and environmentally-friendly, and the like, thereby being beneficial to large-scale popularization and application in tea tree production.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to a special slow-release fertilizer for tea trees using biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] Tea tree is a perennial economic crop for harvesting young and tender tea leaves. It is necessary to pick new green and nutritious young shoots from tea trees many times a year, which consumes a lot of nutrients for tea trees. At the same time, the tea tree itself needs to continuously build vegetative organs such as roots, stems, and leaves quickly, so as to maintain the luxuriance of the tree body, continue to expand and re-grow, and to bloom and bear fruit to reproduce offspring, etc., all of which consume a lot of nutrients. Therefore, rational fertilization is an important measure to increase the yield and quality of tea gardens and promote the growth of tea trees. Tea tre...
