不同基质配方对3种地被植物容器苗生长的影响
Effects of Different Substrates on the Growth of Three Ggroundcover Plants in Container
摘要
Abstract
A four-factor and three-level orthogonal experiment was carried out to study the growth responses of three groundcover plants to substrates with different combinations of coconut leaflets,humus,yellow soil and perlite.The results showed 9 substrates significantly improved the physical and chemical characteristics of soil and mostly achieved the ideal cultivation substrates.Abundant nutrients with higher levels of organic matter,total nitrogen and available phosphorus were founded in T5,T3 and T7 container.Effects of cultivated substrate on the growth index and biomass accumulation of three ground cover plants were different significantly,and the aboveground biomass and underground biomass were the highest at T5 container.The comprehensive evaluation results showed that Verbena hybrida,and Euonymus japonicus ‘ microphylla’ grew best in T5 container,and Ophiopogonjaponicus var.nana grew best on T9 and T3 container.Therefore,the ideal substrate for culturing V.hybrida and E.japonicus ‘microphylla’ was 4 cm-length coconut leaflet:humus:yellow soil with a proportion of 1 ∶ 6 ∶ 4;for O.japonicus var.nana,the formula was 4 cm-length coconut leaflets ∶ humus ∶ yellow soil ∶ perlite with a proportion of 1 ∶ 9 ∶ 4 ∶ 3 or 6 cm-length coconut leaflets:humus:yellow soil with a proportion of 1 ∶ 9 ∶ 2.关键词
