Embodiment 1

[0078] Example 1: The preparation process of the banana-specific slow-release fertilizer 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 a ratio of 71.7% and 28.3%, 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 32.98%.

[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 73.1%, 20.8% Mix with 6.1% ratio, carry out pressure granulation with KP-300 type organic fertilizer granulator, make nitrogen (N) amount 13.16%, contain available phosphorus (P2O5) amount and be 33.63% nitroge...

Abstract

The invention discloses a special banana 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 bananas to prepare the special banana 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 bananas 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 banana production.

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 bananas with biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] In banana production, rational fertilization is an important measure to ensure yield and quality. Banana has huge stems and leaves, rapid growth, large growth volume, and high yield, which determine its year-round good fertility and its sensitivity to fertilizers. At the same time, bananas have high water content, large leaf area, large transpiration, and need more water. In the summer when bananas grow rapidly, constant fertilization and constant watering are required to meet the needs. In the past, in order to reduce the frequency of fertilization, bananas were mostly applied with organic fertilizers with slow nutrient release and long fertilizer efficiency. With the increase of banana pl...
