Special slow-release fertilizer for pineapples with biomass particle carbon as matrix and preparation method of slow-release fertilizer

Abstract

The invention discloses a special slow-release fertilizer for pineapples with biomass particle carbon as a matrix and a preparation method of the slow-release fertilizer. The particle carbon prepared from agricultural waste biomasses such as corncobs, peanut shells, rice husks and edible fungus matrixes is taken as the matrix material, and is compounded with nitrogen, phosphorus, potassium and other nutrient elements necessary for growth and development of the pineapples on the basis of micropores and high adsorption capacity of the particle carbon, thus obtaining the special slow-release fertilizer based on the granular biomass carbon for the pineapples. The biomass particle carbon adopted by the special slow-release fertilizer is black biomass carbon particles prepared from the agricultural waste biomasses which are incompletely combusted under a low-oxygen condition, has a plurality of characteristics similar to those of soil humus, has high capacities of adsorption and maintenance of nutrients and moisture, also can stimulate crop growth, and has good slow release performance to the nitrogen, phosphorus and potassium. The prepared slow-release fertilizer prepared from the biomass particle carbon can effectively supply nutrients required by the pineapples during an entire growth period after being applied once, and has the characteristics of improving land capability and a soil structure, being efficient and environment-friendly, and the like, thereby facilitating large-scale popularization and application of the fertilizer in production of the pineapples.

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 pineapple using biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] In pineapple production, rational fertilization is an important measure to ensure yield and quality. It usually takes 15 to 18 months for pineapple from planting to harvesting the first fruit. During this period, it has experienced the growth of roots, stems, and leaf vegetative organs, the differentiation of flower buds, the emergence of buds and flowering, the development of fruits and the emergence of various buds. Wait for several different stages. It is a vegetative growth period from planting to before fruiting. Fertilization should be based on nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers. The purpose is to promote pineapple leaf extraction, increase the ...

Problems solved by technology

With the continuous expansion of the pineapple planting area, organic fertilizers can no longer meet the needs, and the repeated application of chemical fertilizers has the following disadvantages: first, it increases the labor intensity and labor costs of farmers; After the furrow surface, fertilization in the rhizosphere is difficult and easy to damage the roots

In the burning season, there have been many incidents where flights could not land and highways were forced to close due to the smog in the sky, which not only wasted a lot of precious resources, but also brought serious pollution to the environment.
