发酵粉碎麦秸和过筛炉渣混合制备的有机生态无土栽培基质研究

Study on Organic Ecological Soilless Substrates Prepared from Crushed Straw and Sieving Slag

以粉碎的麦秸和过筛炉渣为试材,研究了"肥士特"、"金宝贝"和‘HM’菌剂3种菌剂对麦秆发酵效果的影响;同时将发酵麦秸与未发酵麦秸和其它常用基质进行了理化性状比较;以发酵后的麦秆与炉渣按一定比例混合,研究了混合基质的理化性质,以期确定最佳的麦秆发酵基质配比。结果表明:发酵后的麦秆理化性质与未发酵的麦秆相比,更接近无土栽培基质的特性,‘HM’菌剂发酵的麦秆效果最佳,发酵麦秆∶炉渣=7∶3比例混合,基质综合效果最佳。

Taking crushed straw and sieving slag as test materials, the effects of ＇ First＇, ＇ Gymboree＇ and ＇ HM＇ on straw fermentation were studied, and the results with unfermented straw and other usual substrates were compared. Fermentated straw and slag were mixed at a certain proportion, and physicochemical properties of the mixed substrate were determinated to obtain the best proportion. The results showed the physieoehemieal properties of fermented straw were closer to the characteristics of soilless culture,compared with unfermented straw. The fermentation of straw which was fermented by ＇HM＇ bacteria was the best. When fermented straw ： slag was 7 ： 3,the optimum comprehensive effect of the substrate was achieved.
