Special slow release fertilizer for lawn using biomass granular carbon as substrate and preparation method thereof

Abstract

The invention discloses a special slow release fertilizer for a lawn using biomass granular carbon as a substrate and a preparation method thereof. Granular carbon prepared from corn cobs, peanut shells, rice hulls, edible fungus substrates and other agricultural waste biomass is used as the substrate material; and through the microporosity and the high adsorptive capacity, the substrate material is compounded with nitrogen, phosphorus, potassium and other nutrient elements necessary for the growth and development of the lawn, thus preparing the granular biomass carbon-based special slow release fertilizer for the lawn. The biomass granular carbon used in the invention is a black biomass granular carbon granule formed by the incomplete combustion of agricultural waste biomass under a low-oxygen condition, has multiple features similar to soil humus, has a high capability of adsorbing and keeping nutrient and moisture, can stimulate the growth of crops, and has favorable nitrogen / phosphorus / potassium slow release performance. When being applied once, the slow release fertilizer prepared from the biomass granular carbon can effectively supply the nutrient required by the lawn for the whole growth period, has the characteristics of soil productivity increasing, soil structure improving, high efficiency, environment friendliness and the like, and is favorable for large-scale popularization and application in lawn culture.

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 lawns with biomass granular carbon as a matrix and a preparation method thereof. Background technique [0003] Lawn fertilization is an important factor to improve lawn quality and maintain lawn durability. Fertilization can timely supplement the insufficient nutrient supply in lawn soil to maintain a high quality level of lawn. The lawn needs fertilizer different from other crops. It mainly grows leaves and needs more nitrogen than other crops. However, the supply of nitrogen should not be too much or too fast, otherwise the lawn will grow too fast, which will not only increase the number of pruning, but also increase the labor load. , It will also reduce the ornamental quality, and the nutrient supply that the lawn needs, especially the nitrogen supply, is stable and long-lasting. Most of the more high-e...
