摘要
以黄瓜品种津育5号为试材,以传统的草炭、珍珠岩混合基质作对照,分析配比不同比例柠条的混合基质的容重、总孔隙度、通气孔隙度、持水孔隙度、大小孔隙比及pH值、EC值等理化性状,并对不同基质培育的黄瓜幼苗生长相关指标进行研究。结果表明:经过合理配比的柠条基质在理化性质方面基本符合育苗要求,使用柠条基质育苗的黄瓜幼苗出苗率、长势和质量均优于传统的草炭基质;综合比较,以柠条∶珍珠岩=1V∶1V的混合基质育苗效果最佳。
Caragana Korshinskii Kom was chosen to be used with very good results as growth media instead of peat.The parameters of the compound substrates were tested,including bulk density,total porosity,aeration porosity,water-holding porosity,porosity ratio,and pH and EC values.Experiments were conducted with cucumber'Jinyu No.5'nurseries using caragana-included substrates.Rate of emergence,seedling dry and wet matter were also tested to figure out the effects that caragana had shown upon cucumber seedling.The results indicate that 50% of caragana-included substrate,being thoroughly decomposed,has the best quality for cucumber seedling,as compared with the traditional peat substrates.So the caragana-included substrates are feasible to replace peat substrates.
