Abstract

The invention belongs to the field of landscaping, and provides a controlled-release nutritional type soilless lawn matrix. The controlled-release nutritional type soilless lawn matrix is composed of the following raw materials in parts by weight: 30-40 parts of rice chaff powder, 25-30 parts of spent mushroom compost, 10-15 parts of sasangua cake having grain size less than 5mm, 15-20 parts of humic acid phosphorus-potassium fertilizer, and 5-10 parts of calcium sulfate. The spent mushroom compost and the sasangua cake of which the grain size is less than 5mm are separately fermented or fermented after being mixed, the microbial zymophyte is added for fermenting, the mass content ratio of C to N in the material is regulated to be less than 25, and after sufficient fermenting, the humic acid phosphorus-potassium fertilizer, the rice chaff powder and calcium sulfate are added according to the above proportion and then uniformly mixed to obtain the controlled-release nutritional type soilless lawn matrix. The controlled-release nutritional type soilless lawn matrix provided by the invention is high in nutrient content, small in maintenance, capable of reducing nutrient loss, improving the nutrient utilization rate, and is in favor of the environmental protection.

Description

technical field [0001] The invention belongs to the field of landscaping, and is mainly used in slow-release nutrient soilless lawn substrates and preparation methods thereof in the fields of soilless lawn grass cultivation, courtyard greening, urban roof greening, vertical greening, road greening, etc. Background technique [0002] At present, in the preparation and production of soilless lawn substrates, most of the attention is paid to the physical properties of the substrate such as air permeability and water retention. Affected by factors such as the complexity of the substrate processing technology and cost, the combination of substrate nutrients is mostly water-soluble. The fast-acting nutrients in the substrate will lead to the uneven supply of nutrients in the growth process of the grass, which will lead to uneven grass phase, high incidence of disease, and difficult maintenance. If the lawn is planted in a place where the soil is poor and difficult to maintain, the ...
