Problems solved by technology

In my country's lawn nutrient management, imported compound fertilizers or domestic agricultural fertilizers are usually used, and the ratio of N:P in imported compound fertilizers is 2 o 5 : K 2 O is 15:15:15 (weight percentage) type is the most common, and the application of domestic fertilizers is usually urea, supplemented by a certain proportion of potassium chloride fertilizer. Reasonable formulation of fertilizer characteristics will lead to poor fertilization effect, poor lawn quality, and even environmental pollution caused by fertilizers.

Description

technical field [0001] The invention belongs to fertilizers, in particular to a warm-season lawn grass fertilizer. Background technique [0002] With the rapid development of the urban economy, people's living standards continue to improve, and the requirements for the living environment are getting higher and higher. The lawn area of ​​residential quarters and urban greening continues to expand. At present, the lawn greening area in my country has reached 1.5 billion square meters, and the lawn industry has developed into A new type of industry. However, due to the late start of the development of the turf industry in our country, there are many problems in management. The trend of "reuse and lack of maintenance" in the development of the turf industry is very serious, which greatly affects the life and quality of the turf. Among them, the problem of turf nutrient management is the most prominent problem among these problems. "Replanting, light care" is an urgent problem to...
