红锥容器育苗基质选择试验研究
|
摘要
将沤制松树皮、炭化松树皮、珍珠岩和黄心土4种材料按不同比例配制成6种基质配方,开展红锥育苗试验,通过不同基质理化性质与生长指标的相关分析,应用主成分分析对其育苗效果进行综合评价,旨在筛选出适宜红锥育苗生长的基质。结果表明,基质持水量与苗高、地上部分生物量和总生物量及苗木出圃率成显著或极显著负相关,是影响红锥苗木生长的关键因素;各基质育苗效果综合评价得分值由大到小顺序为沤制松树皮60%+珍珠岩20%+黄心土20%、沤制松树皮40%+珍珠岩40%+黄心土20%、沤制松树皮60%+黄心土20%+炭化松树皮20%、沤制松树皮40%+黄心土40%+炭化松树皮20%、沤制松树皮40%+珍珠岩40%+炭化松树皮20%、沤制松树皮60%+珍珠岩20%+炭化松树皮20%。建议生产上采用沤制松树皮60%+珍珠岩20%+黄心土20%作为红锥的育苗基质。
Six matrix formulations were prepared from four materials in different proportions,such as pine bark,charred pine bark,perlite and forest soil,which used to carry out the red cone seedling test.In order to screen the suitable substrate for the growth of red cone seedlings,the correlation analysis between the physical and chemical properties of different substrates and growth indicators was applied,principal component analysis was applied to comprehensively evaluate the seedling effect.The results showed that there was a significant or extremely significant negative correlation between substrate moisture content and seedling height,aboveground biomass,total biomass and seedling emergence rate,which were the key factors affecting the growth of C.hystrix seedlings.The comprehensive evaluation score of seedling effect of each substrate was in the order of 60% retting pine bark+20% perlite+20% soil,40% retting pine bark +40% perlite+20% soil,60% retting pine bark+20% soil+20% carbonized pine bark,40% retting pine bark+40% soil+20% carbonized pine bark,40% retting pine bark+40% perlite+20% carbonized pine bark,60% retting pine bark+20%perlite+20% carbonized pine bark.It is suggested that 60% retting pine bark+20% perlite+ 20% soil could be used as the seedling raising matrix of C.hystrix.
