不同配比的椰糠与珍珠岩基质对番茄幼苗生长和育苗效果的影响
Effects of Different Coir Dust to Perlite Ratio Substrate on Growth and Seedling Raising Effect of Toma-to Seedling
摘要
Abstract
Using common tomato cultivar Baiguoqiangfeng as the experimental material, physical and chemical properties of mixed substrate of different coir dust to perlite ratio were measured, the effects of these substrates on growth parameters of tomato seedlings were studied by soilless seedling-raising method, and tomato seedling-raising effect were analyzed. The results indicated that bulk density and electrical conductivity of mixed substrate decreased,large to small porosity ratio increased and mixed substrate was more accordant with the conditions of soilless culture after adding appropriate amount perlite into coir dust substrate; emergence rate, seedling-forming rate, plant height, leaf area, fresh and dry mass of shoot and root, chlorophyll content, root to shoot ratio, strong seedling index increased by mixed substrate of appropriate coir dust to perlite ratio,and 40% coir dust+60% perlite (volume:volume) was preliminarily regarded as more suitable mixed substrate to growth of tomato seedling than the other ratios.关键词
