摘要
以黄瓜品种戴多星和春秋王为试材,分别用商品岩棉条和椰糠条进行育苗和栽培试验,探究不同栽培基质对黄瓜生长、光合、产量和果实品质的影响。结果表明,第1片真叶展开后26 d,椰糠基质栽培的黄瓜幼苗茎粗、第2~4片真叶叶面积均高于岩棉栽培的黄瓜幼苗。椰糠基质栽培的黄瓜叶片光合速率、气孔导度和单株产量(采收25 d后)显著高于岩棉栽培,并且椰糠基质栽培的黄瓜果实干质量占总干物质量的比例也较高。椰糠基质栽培黄瓜的可溶性糖和VC含量高于岩棉栽培的黄瓜。综合黄瓜苗期和成株的生长来看,椰糠基质能够在一定程度上促进黄瓜植株的生长,获得较高的果实品质,适宜在黄瓜温室育苗和生产中推广使用。
Taking cucumber varieties‘Daiduoxing’and‘Chunqiuwang’as test materials,this paper carried out seedling and cultivation experiment using commercial rock wool strip and coco coir strip,respectively;and studied the effects of different cultivation substrates on cucumber growth,photosynthesis,yield and fruit quality.The results showed that after the first true leaf unfolded 26 days the stem diameter and the 2nd to 4th leaf area of cucumber seedlings cultured in coco coir substrate were all higher than that of cucumber seedlings cultured in rock wool substrate.Cucumber plants grown in coco coir substrate had significantly higher net photosynthetic rate(Pn),stomatal conductance(Gs)and yield of signal plant(25 days after harvest)than that of the plant cultured in rock wool substrate.And also the ratio of cucumber fruit dry matter weight in total dry matter was higher.The contents of soluble sugar and VC in cucumber cultivated in coco coir substrate were higher than that of the cucumber cultivated in rock wool substrate.In conclusion,coco coir substrate could promote the growth of cucumber by certain degree and obtain higher fruit quality.Commercial coco coir was suitable in its popularization and application in greenhouse for cucumber seedling and production.
