Slow-release fertilizer special for lotus root using biomass particle carbon as matrix and preparation method thereof

Abstract

The invention discloses a slow-release fertilizer special for a lotus root using biomass particle carbon as a matrix and a preparation method thereof. The particle carbon prepared by agricultural waste biomass such as corn cobs, peanut hulls, rice husks and edible fungus matrixes is the matrix material; the particle carbon is compounded with nitrogen, phosphorus, potassium and other nutrient elements which are needed by the growth of lotus roots through plurality of micropores and strong capacity of the particle carbon, so that the granular biomass carbon-based slow-release fertilizer special for the lotus root is prepared. The biomass particle carbon used by the slow-release fertilizer is black biomass particle carbon particles which are generated by incompletely burning the agricultural waste biomass under a low oxygen condition; the biomass particle carbon has a plurality of features similar to the features of soil humus, strong capacities of absorbing and maintaining nutrients and water, and good slow-release performance for nitrogen, phosphorus and potassium, and also can stimulate the growth of crops; the slow-release fertilizer prepared in such way is fertilized once, the nutrients required by lotus roots in the whole growth phase can be effectively supplied; and the slow-release fertilizer has the characteristics of increasing soil fertility, improving soil structure, efficiency, environment protection and the like, and is in favor of being large-scale popularized and applied in lotus root 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 lotus root with biomass granular carbon as a substrate and a preparation method thereof. Background technique [0003] The lotus root grows underwater, which brings a lot of inconvenience to fertilization management. After the lotus root is fertilized, it must be turned into the soil. One is to be close to the root system after being put into the soil, which is easy to absorb. The other is to prevent a large amount of nutrients from dissolving in the water, which will make the water body eutrophic, which is not good for the growth of the lotus root. At present, in addition to some organic fertilizers, the main types of fertilizers for lotus root production are urea, potassium chloride, and compound fertilizers. These fertilizers are quick-acting fertilizers that dissolve quickly in the soil, and the concen...
