| 摘 要： | 设置5、10、15目3个不同粉碎度的椰糠基质，按照椰糠∶蛭石=3 V∶1 V进行复配，以草炭∶蛭石=3 V∶1 V为对照，通过研究基质的理化性质（容重、总孔隙度、持水孔隙度、pH、电导率）及其对黄瓜幼苗生长发育的影响，筛选出适宜黄瓜幼苗生长的椰糠基质粉碎度。结果表明，在3个不同的粉碎度中，10目粉碎度的处理最有利于黄瓜穴盘苗的生长。植株达到了较为理想的生长状态，壮苗指数、根冠比、干质量，以及幼苗中叶绿素含量和净光合速率等较其他两个处理均有所提高。

| Abstract: | Three treatments with different grinding degrees of coconut coir substrate including item 5,10,15,were designed.The ratio between coconut coir and vermiculite was 3 V:1 V.The physical and chemical properties of unit weight,total porosity,water holding pores,pH,conductivities and different physiological and biochemical indexes were investigated by comparing with the control of peatmoss:vermiculite = 3 V:1 V,so as to screen out an optimal formula.The results showed that among 3 different grinding degrees,treatment of item 10 was in favor of cucumber growth.The plant had reached an ideal growth state:cucumber seedling index,root shoot ratio,dry weight,chlorophyll content of seedling,net photosynthetic rate were all better than the other 2 treatments. |
