摘  要：
用无机惰性材料(珍珠岩)和有机物料(农业废弃物)作为基本原料,加入结构改良剂复合而成的两种复合基质进行黄瓜温室栽培试验,以珍珠岩为对照,从基质的理化性质、水分养分吸附、水分常数和产量、收益等方面分析了复合基质的特性和栽培效果。研究结果表明,复合基质的理化性质比较适中,结构比较合理,并具有较强的水分养分吸附性能,增强了对营养液的养分吸附和对黄瓜的营养供应,其中复合基质2号吸附的水分对黄瓜的有效性高,有利于减少营养液和水分的灌溉量、提高养分和水分的利用率,可使黄瓜产量比采用较成熟的珍珠岩栽培技术增产22.6％,增收20.9％。

摘  要：
The physi-chemical properties of substrate influenced absorption of nutrition and water, and rhizotzxy growth. So, substrate was the most principal factor effect on growth environment of plant rhizos-phere in soilless culture. In this article, the 2 kinds of compound substrates, which were made from indifferent material and organic compost, were planted cucumber in greenhouse, with the control of perlite. The physi-chemical properties and effect of the substrates were evaluated with the criteria of structure, water and nutrient absorption, index of water constants, yield, cost, and benifit. Results showed that physi-chemical properties of substrate No. 2 were suitable for plant roots growth. It could absorb more nutrients than that of perlite, and had high water efficiency for plant using. The cucumber yield and benifit are also enhanced to the degree of 22.6% and 20.9% respectively.
