木屑菇渣复配基质理化性状分析及其对黄瓜幼苗生长的影响
Physical and Chemical Properties of Compounded Sawdust Mushroom Residue Substrate and Its Effects on Growth of Cucumber Seedlings
摘要
Abstract
In this study,the basic medium with volume ratio of peat to vermiculite as 2∶1 was chosen as control,and 4 compounded substrates were designed by adding mushroom residue of 0.5,1,1.5 and 2 times volume.Their physical and chemical properties were analyzed,and the effects on growth and quality of cu-cumber seedlings were studied.The results showed that with the increase of mushroom residue in the four de-signed prescriptions,the bulk density,total porosity and water -holding porosity decreased gradually,while the aeration porosity showed a trend of increase.For all treatments,the air -water ratio was 1 ∶2.02 ~1∶2.43,the pH value was 4.25 ~7.03,the EC value was 2.64 ~5.01,and they all contained rich NPK nu-trients.The pH,EC value and contents of alkaline nitrogen,available phosphorus and available potassium all increased with the increase of mushroom residue content.For different treatments,the healthy index of cucum-ber seedlings appeared in a descending order as T1 >T2 >T3 >CK >T4.It indicated that T1,T2 and T3 treatment could substitute the basic medium of peat and vermiculite,among which,T2 and T3 treatment with the replacement rate of mushroom residue as 50% and 75% were considered as ideal candidates.关键词
