Embodiment 1

[0078] Example 1: The preparation process of the special slow-release fertilizer for mulberry trees with biomass granular carbon as the substrate

[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 proportions of 66.5% and 33.5%, 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 30.59%.

[0081] (2) Take diammonium phosphate powder with 18% nitrogen (N) content and 46% available phosphorus (P2O5) content, 80 mesh biomass granular carbon particles and binder, according to 70.6%, 22.8% Mix with 6.6% ratio, carry out pressure granulation with KP-300 type organic fertilizer granulator, make nitrogen (N) amount 12.71%, contain available phosphorus (P2O5) amount and ...

Abstract

The invention discloses a special slow release fertilizer for mulberry by using biomass granular carbon as a matrix and a preparation method thereof. Granular carbon prepared from agricultural wastes such as corn cobs, peanut shells, rice hulls, edible fungi matrix and the like are used as a matrix material; and based on the micro-pores and strong adsorption capability of the matrix material, the granular biomass carbon-based special slow release fertilizer for the mulberry is prepared by compounding the matrix material and nitrogen, phosphorus, potassium and other nutritional elements required by growth and development of the mulberry. The biomass granular carbon is black biomass granular carbon granules formed after the agricultural waste biomass is incompletely burnt under the low-oxygen condition, has multiple properties similar to soil humus and strong adsorption and nutrient and moisture holding capabilities, can stimulate growth of crops, and has good slow release performance on nitrogen, phosphorus and potassium; when the prepared slow release fertilizer is applied at one time, the requirements of the mulberry for nutrients in the whole growth period can be effectively met; and the slow release fertilizer has the characteristics of increasing soil fertility, improving the structure of soil, realizing high efficiency and environment friendliness and the like, and is beneficial to large-scale popularization and application in the production of the mulberry.

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 mulberry trees using biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] Reasonable fertilization is an important measure for stable, high-yield, and high-quality mulberry leaves. Mulberry is a perennial woody plant, the main purpose of cultivation is to pick mulberry leaves. Because mulberry leaves are harvested and pruned many times every year, mulberry trees will take away a large amount of nutrients from the soil. If they are not replenished in time, the soil nutrients will be deficient, which will affect the normal growth of mulberry trees and lead to tree vigor decline. At present, the chemical fertilizers used for mulberry trees are mainly quick-acting fertilizers. These fertilizers dissolve quickly after being applied to the soil and a...
