Medium production method of soilless lawn adaptive to arid area

Abstract

The invention relates to a medium production method of a soilless lawn adaptive to an arid area, which comprises the following steps of: 1) selecting cold-season lawn grass as seeds; 2) mixing slag and organic sludge composts in proportion to form a growth medium layer; 3) mixing leftovers obtained during mushroom production, sawdust and stalk powder in proportion, and sequentially adding water-retaining agent and slow release fertilizers to form a water-retaining nutritional slow release material layer; 4) laying a plastic mulching film on the ground as an isolating layer, and then laying a polypropylene sunshade net as the bottom layer of the lawn; 5) firstly laying the growth medium layer and then laying the water-retaining nutritional slow release material layer on the bottom layer ofthe lawn; 6) evenly sowing the seeds to form a seed layer and using lawn special non-woven fabrics to cover the seed layer to form a sprout protection layer, wherein the construction of a lawn bed iscompleted; 7) controlling the growth environment of the lawn bed; 8) watering everyday at a seedling stage to keep the surface of the lawn bed to be moist; and 9) conducting indicator determination after the lawn is formed. The medium production method of the soilless lawn adaptive to the arid area has the advantages of low raw material cost, reasonable structure, high water-retaining capacity and simple production method, and is suitable for climates in arid and semiarid areas.

Description

Technical field [0001] The invention belongs to the technical field of the production of urban greening soilless lawns, and particularly relates to a substrate production method adapted to soilless lawns in arid areas. Background technique [0002] In the past 20 years, my country's lawn greening has developed rapidly, and the lawn area has been continuously expanded. With the continuous increase in environmental construction and urban landscaping demand, the demand for high-quality turf has also been increasing. The application of carpet turf in my country started relatively late. Only in the early 1980s did the introduction of "new technology of carpet rug production" and "lawn planting belt method" from abroad began. Many scholars have conducted research on carpet lawns. The results show that carpet lawns not only maintain the advantages of soilless turf without weeds and pests, uniform appearance, neat structure, consistent color, etc., but also have easy-to-master cultivatio...

AI Technical Summary

Problems solved by technology

However, in the arid and semi-arid areas of Northwest my country, the amount of evaporation is large, and it needs to be irrigated more than 4 times a day to ensure its survival. The thin substrate layer can easily cause drought stress on turfgrass, affect the quality of turf, and bring great difficulties to the maintenance and management of soilless turf.

Therefore, although soilless lawns have many advantages, they cannot be popularized and applied in arid and semi-arid areas.
