摘要:
 为筛选出适合杉木优良无性系洋-061容器苗生长的轻型基质配方。采用单纯形-重心混料试验设计，以泥炭土、珍珠岩、杉木皮和稻谷壳为材料，并以黄心土为对照（CK），研究不同轻型基质配比对杉木生长、根系形态和养分积累的影响。结果表明，1）不同轻基质配方（T1-T14）和对照（CK）处理的苗高、地径和生物量均表现出相同的生长规律，即随时间增加而逐渐增大。2）当苗木培育360 d时，不同轻型基质处理苗高、地径和苗木质量指数均高于CK，其中，苗高在T6处理最大，较CK增加了54.89%，地径和苗木质量指数在T6和T1处理时达到最大，分别较CK提高33.04%和48.65%，T14处理下生物量最大；3）不同轻型基质处理有效促进了杉木幼苗根系的发育，而且其总根长、根表面积、根直径及根体积分别在T2、T14、T9和T14处理时达到最大；4）杉木植株养分含量对不同轻型基质响应存在差异，其中轻型基质T5、T3和T12处理显著促进植株氮的积累，轻型基质T8、T3和T13处理苗木全磷含量显著高于其他处理，而T8、T9和T2植株全钾含量显著高于其他处理；5）利用隶属函数对幼苗生长指标进行综合分析，综合评价排名前3的依次是T14（20%泥炭土+27%珍珠岩+27%杉木皮+26%稻谷壳）、T5处理（60%泥炭土+40%珍珠岩）和T1处理（100%泥炭土）。考虑到泥炭土成本较高，因此，T5和T14处理为本研究中适合于杉木洋-061容器苗生长的轻型基质配方。
Abstract:
 In order to screen out the light medium formula suitable for the growth of superior clone of Yang-061 container seedlings of Cunninghamia lanceolata,the effects of different light substrates,such as peat soil,perlite,C.lanceolata bark and rice husk and their ratios on the growth,root morphology and nutrient accumulation of C.lanceolata with yellow soil used as the control (CK) were studied by using simplex centroid mixture design.The results showed that 1) compared with CK,the seedling height,ground diameter,biomass and seedling quality index showed the same growth rhythm in different light substrate formula,namely the growth increased with time.2) After 360 days of cultivation,the seedling height,ground diameter and seedling quality under different light substrate treatments were all higher than CK.Among them,the seedling height was the highest in T5 and T6 treatments,which increased by 54.41% and 54.89% respectively compared with CK.The ground diameter and seedling quality index reached the maximum value in T6 and T1 treatments,which were 33.04 %and 48.65 %,higher than CK,the biomass achieved its maximum in T14.3) Different light substrate treatments effectively promoted the root development of C.lanceolata seedlings,and the total root length,root surface area,root diameter and root volume reached their maximum values in T2,T14,T9 and T14 treatments,respectively.4) The response of nutrient content of C.lanceolata seedlings to different light substrates was different among treatments.The light substrates of T5,T3 and T12 treatments significantly promoted the accumulation of nitrogen in plant,the light substrates of T8,T3，T13 significantly increased the total phosphorus content of seedlings,while the T8,T9 and T2 treatments significantly increased the total potassium content of seedlings.(5) The comprehensively analysis results analyzed by the subordinate function value method showed the top three light substrate suitable for the growth of C.lanceolata were T14 (20% peat soil +27% perlite +27% C.lanceolata bark +26% rice husk),T6 (60% peat soil +40% perlite) and T1 (100% peat soil).Considering the high cost of peat soil,T5 and T14 treatments were selected as light substrates suitable for the growth of C.lanceolata Yang-061 container seedlings in this study.
