摘要
概述了基质的理化性状,分析了基质理化性状对蔬菜生长发育的影响,并通过不同学者对基质栽培固体基质理化性状的研究,总结出蔬菜栽培基质适宜的理化性状:容重0.2~0.8 g/cm3,总孔隙度70%~90%,气水比1∶2~4,电导率1.00~3.49 m S/cm,p H值6.5~7.0,阳离子交换量10~100 cmol/kg。
Index of substrate physicochemical properties was summarized,effect of substrate physicochemical properties on vegetable cultivation was analyzed.Based on the research of different scholars on physicochemical properties of solid cultivation substrates,the paper summarized the suitable physicochemical properties for substrate of vegetables cultivation.Suitable density was 0.2~0.8 g/cm^3,total porosity was 70%~90%,gas water ratio was 1∶2-4,conduc-tivity was 1.00-3.49 mS/cm,pH value was 6.5-7.0,cation exchange capacity was 10-100 cmol/kg.
