A Study on the Application of Agricultural Residue in Cultivation Substrate of Orchid

农业废弃物在兰花栽培基质中的应用研究（英文）

Five different substrates were prepared using oyster mushroom residue,rice straw,peat soil,pine bark,volcanic rock and perlite.Orchids(variety Chunjian)were cultivated on these five substrates with substrate being made from aseptic residue and straw as the control.The changes of physical and chemical properties of substrates and the growth of orchids were observed after three months.The results showed that the physical and chemical characters of the treatments and the control each had its own advantage,and there were no significant differences in the cultivation effects of all treatments.Therefore,the mushroom residue and decomposed rice straw are good substitutes for peat soil as soilless culture substrate in orchid cultivation.This research provides a scientific basis for the transformation of agricultural wastes into useful materials and can greatly stimulate the development of related industries.

用平菇菌渣、水稻秸秆、泥炭土、松树皮、火山石、珍珠岩为原料,配制5种不同的基质,以无菌渣和秸秆配制的基质为对照,在5种基质上栽培兰花(品种为春剑),3个月后观测基质理化性状的变化和兰花的生长情况。结果表明:各处理与对照的理化性状各有优势,栽培效果差异不明显。因此,菌渣和腐熟的水稻秸秆可代替泥炭土作为兰花的无土栽培基质。这为农业废弃物变废为宝和相关产业发展提供了科学依据。
