Abstract

The invention provides a method for improving urban green land soil with wood vinegar fertilizer. The method comprises the following steps of: 1, selecting an urban green land to be improved, and detecting the physical and chemical properties of the soil; 2, preparing the wood vinegar fertilizer; 3, applying the wood vinegar fertilizer to the urban green land soil to improve the soil. According to the method, the wood vinegar fertilizer is applied to the urban green land soil to improve the physical and chemical properties of the soil. With the adoption of the method, the EC value, pH value, and soil bulk density of the soil can be reduced; the content of organic substances in the soil, the content of available nutrient, the number of microorganism and the total porosity can be increased; the method is beneficial for the growth of landscape plant in the green land as well as the achievement of landscape effect of the green land, and has high practical and economic value.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving urban green land soil by using wood vinegar fertilizer. Background technique [0002] As the process of urbanization continues to accelerate, the quality of the urban ecological environment has received increasing attention. The urban soil is an important component of the urban ecosystem, a medium for the growth of garden plants and a supplier of nutrients, and the foundation of urban green space. In view of the increasing soil problems in urban green space, improving its physical and chemical properties has become inevitable, and it is also a current research hotspot. As a new type of organic fertilizer, wood vinegar fertilizer has attracted much attention in Japan, South Korea and other countries in recent years, and its research and application have become increasingly widespread, but it is still in its infancy in China, and relevant research and ...
