Wormcast application method for urban park green land soil improvement

Abstract

The invention belongs to the technical field of soil improvement, and particularly relates to a wormcast application method for urban park green land soil improvement. The method comprises the following steps of preparing an earthworm culture material: mixing pure cow dung and straws according to a ratio of 2: 1 to obtain the earthworm culture material; selecting the varieties of earthworms: selecting the earthworms which have more varieties and are higher in environmental adaptability, suitable for artificial breeding and domestication and higher in reproductive capacity, and breeding the earthworms; artificially breeding earthworms: breeding the selected varieties of earthworms in the earthworm culture material, controlling and adjusting the temperature and humidity in a culture medium, and putting enough bait to the earthworms. According to the method, the wormcast nutrient soil special for urban parks is provided. The method improves the content of organic matters in the soil, maintains the acidity and alkalinity of the soil, improves the granular structure of the soil from the source, improves the soil, is simple in step and easy to operate, has economic benefits, reduces the environmental ecological risk and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for applying vermicompost for soil improvement in urban park greenbelts. Background technique [0002] Most of the soil in urban parks and green spaces is urban construction waste backfill, river sludge, etc. The soil quality is extremely poor, and the current fertilization schemes for green space soil are mixed. Most of the fertilizers are livestock and poultry manure-type fertilizers, which cannot effectively improve the soil. Traditional vermicompost has low organic matter content. , About 28%, low humic acid content, resulting in high fertilization costs. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology. The invention provides an application method of vermicompost for soil improvement of urban park green spaces, which has the characteristics of improving soil aggregate struct...
