容器规格对杉木幼苗培育的影响

采用单因素随机区组设计,开展了5种不同容器规格(13 cm×18 cm、12 cm×16 cm、10 cm×15 cm、9 cm×13 cm、8 cm×11 cm)对杉木幼苗培育的影响的试验,结果表明:5种容器规格培育的杉木幼苗生长量和生物量间差异显著。容器规格为13 cm×18 cm培育的杉木幼苗的生长量和生物量明显优于其它4个容器规格,提高了苗木质量。相比较容器规格为8 cm×11 cm,苗高、地径、冠幅、主根长、地上部分干重、地下部分干重、全株干重分别高出1.53%,33.61%,54.62%,17.56%,63.72%,68.97%和65.23%。容器规格为13 cm×18 cm的育苗成本为0.675元/株。

Influence of Container Size on the Seedling Cultivation of Cunninghamia lanceolata

The effects of container size on the growth and biomass of Cunninghamia lanceolata seedlings were studied by using single factor randomized block design.The materials of tested containers were non-woven fabric.Five sizes of containers were tested,namely 13 cm×18 cm,12 cm×16 cm,10 cm×15 cm,9 cm×13 cm and 8 cm×11 cm respectively.After 6 months cultivation,the growth and biomass of tested Cunninghamia lanceolata seedlings were measured and the data were analyzed.It was found that the seedlings cultivated using the containers of 13 cm×18 cm got significantly higher growing performance than the other four container sizes.Compared with the container size of 8 cm×11 cm,the seedling height,basal diameter,crown width,main root length,aboveground dry weight,underground dry weight and whole plant dry weight were increased by 1.53%,33.61%,54.62%,17.56%,63.72%,68.97%and 65.23%respectively.The cost of raising seedlings with container size of 13×18 cm is 0.645 yuan/plant.
