Slow release fertilizer special for peach trees by using biomass granular carbon as matrix and preparation method for slow release fertilizer

Abstract

The invention discloses a slow release fertilizer special for peach trees by using biomass granular carbon as a matrix and a preparation method for the slow release fertilizer. Granular carbon prepared from agricultural wastes such as corn cobs, peanut shells, rice hulls and edible fungi matrix 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 slow release fertilizer special for the peach trees is prepared by compounding the matrix material and nitrogen, phosphorus, potassium and other nutritional elements required by growth and development of the peach trees. 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 peach trees 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 and realizing high efficiency and environment friendliness, and is beneficial to large-scale popularization and application in the production of the peach trees.

Description

[0001] technical field [0002] The invention belongs to the technical field of agricultural fertilizer production, in particular to a special slow-release fertilizer for peach trees using biomass granular carbon as a matrix and a preparation method thereof. Background technique [0003] Peach trees are light-loving, drought-tolerant, waterlogging-resistant, fast-growing, and high-yield fruit trees. They have a large annual growth rate, are sensitive to nutrients, and have high demand. There are two basic requirements for fertilizing peach trees. One is that the effective time of the fertilizer should be long. In the annual growth cycle, peach trees have 8-9 months to absorb nutrients; the other is that the roots of peach trees are mainly distributed in 20-50 cm In the soil layer, when fertilizing, it should be dug and turned in the root zone to play a role. At present, the types of fertilizers used by peach trees include organic fertilizers and chemical fertilizers. Or...
