Special eggplant slow-release fertilizer using biomass granular carbon as matrix and preparation method thereof

Abstract

The invention discloses a special eggplant slow-release fertilizer using biomass granular carbon as a matrix and a preparation method thereof. By using micropores and strong adsorption capacity of the granular carbon prepared from corn cob, peanut shell, rice hull, edible fungus matrix and other agricultural waste biomass used as the matrix material, the matrix material is compounded with nitrogen, phosphorus, potassium and other nutrient elements which are necessary for growth and development of eggplants to prepare the special eggplant slow-release fertilizer based on granular biomass carbon. The biomass granular carbon used in the invention is black biomass granular carbon formed by incomplete combustion of agricultural waste biomass under low-oxygen conditions, and has multiple characteristics similar to soil humus; and the biomass granular carbon has strong capability for adsorbing and keeping nutrients and moisture, can stimulate plant growth, and has favorable slow release property for nitrogen, phosphorus and potassium. The slow-release fertilizer can effectively supply nutrients required by the eggplants in the whole growth period after being applied once; and the slow-release fertilizer can increase the soil fertility and improve the soil structure, has the characteristics of high efficiency, environmental protection and the like, and is beneficial to large-scale popularization in eggplant 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 eggplant using biomass granular carbon as a matrix and a preparation method thereof. Background technique [0003] In eggplant production, rational fertilization is an important measure to ensure yield and quality. Eggplant is an unlimited-growing crop, which can bloom and bear fruit continuously, and has a considerable period of time for stem and leaf growth and fruiting to proceed simultaneously. The vegetative growth and reproductive growth of eggplant must be coordinated to achieve high yield and high quality. Otherwise, excessive nutrition, especially too much nitrogen, will easily cause fruit drop and yield reduction due to excessive plant growth; if the nutrition is insufficient, stem and leaf growth and reproductive growth will Competing for nutrients makes the fruit small and of poor q...
