摘要
本试验就黄瓜无土栽培的基质与营养液之间,是否存在交互作用的问题进行了研究。在蛭石,蛭石+沙、蛭石+草炭三种基质中,分别浇以含有10%及50%NH_4-N 的两种营养液,看其对黄瓜(Cucu-mis sativus L.cv)生长发育、产量形成及矿物质营养的影响。试验结果表明,在基质与营养液之间存在着显著的交互作用。其中蛭石+沙为基质,并浇以含50%NH_4-N 营养液的处理组合,效果较好。
This study evaluated the influence of three media and two nutrient solutions on growth,development,yield and composition of mineral of cucumber(Cucumis sativus L.cv.Nong Da 14).The results were as follows: The significant interaction was found between media and nutrient solution. The best result was obtained from that plant with 50% NH_4-N in 30% vermi- culite+70% sand(in volume).
