A soil-free lawn planting substrate and a manufacturing method therefor

Abstract

The invention belongs to the field of soil-free culture substrates for garden plants and mainly solves the technical problems of high costs, complicated preparation and poor lawn growth promoting effect of substrates in a soil-free lawn production process. The invention specifically provides a soil-free lawn planting substrate and a manufacturing method therefor. The substrate is prepared from carbonized rice husks, coco coir and turf, with the matching volume ratios being 50%, 45% and 5% respectively. The manufacturing method comprises the steps of removing foreign matter from carbonized rice husks and drying the carbonized rice husks to make the water content lower than 15%; screening coco coir with a 10mm screen to remove macrofibers; finally mixing carbonized rice husks, coco coir and turf uniformly according to the volume ratios of 50%, 45% and 5%. The soil-free lawn planting substrate has the advantages of easy obtaining of raw materials, low cost, rich nutrients and great water retention; the substrate is especially suitable for lawn seed and grass stem planting and can shorten a lawn forming period for more than 15 days.

Description

technical field [0001] The invention belongs to the field of soilless culture substrates for garden plants, in particular to a soilless lawn planting substrate and a manufacturing method thereof. Background technique [0002] Soilless turf is a turf product produced by using agricultural waste as a soil substitute and planting gramineous plants on it. Compared with traditionally produced turf with soil, soilless turf has the following advantages: ①Short production cycle, spring and summer , It takes about 30-45 days in autumn, about 50 days in winter, and it takes 3-4 months for a lawn with soil to grow into a lawn; ②It does not rely on soil for production, which reduces the consumption of soil in the cultivated layer and facilitates factory production. According to Liu Xiufeng According to the calculation, the annual output of three-layer three-dimensional cultivation in the greenhouse can reach more than 7 times that of open field production; ③Using waste as the matrix mat...
