水稻秸秆与园林基质混配用作无土草毯生产技术研究OACSTPCD

In order to select the suitable substrate formula of soilless grass blanket and reduce the production cost of soilless grass blanket,rice straw and garden substrate were mixed according to different proportions,and two kinds of bacteria from different sources were added for aerobic fermentation.The physical and chemical properties,plant toxicity and turf proper-ties of different mixed substrates were compared and analyzed.The results showed that the physical properties of the sub-strate fermented with Beijing Jinbao fungus and the volume ratio of rice straw to garden substrate at 6∶4 were ideal,the content of organic matter was significantly higher than that of other treatments,and its nutrient content was more balanced,the content of heavy metals meetes the requirement of the standard of NY/T525-2021 organic fertilizer,and the turf pro-perties of grass blanket were significantly higher than those of other treatments.This formula substrate is more suitable for soilless grass blanket cultivation.
