容器类型和规格对油松容器苗生长的影响

Effect of Container Types and Specification on Growth of Pinus tabulaeformis Seedlings

通过采用不同类型和规格的容器进行油松育苗试验,测定了1年生长期后油松容器苗的苗高、地径、主根长和总根长等生长指标,分析不同容器类型和规格对油松容器苗生长的影响。结果有明:苗高和地径以硬塑料容器处理最大,分别达到了15.5cm和2.66mm;苗木主根长以小规格黑色塑料容器处理最大,达到29.8cm;苗木根系总长以大规格黑色塑料容器最大,达到740.4cm。可见,硬塑料容器有利于油松容器苗地上部分生长,黑色塑料容器对容器苗根系生长促进效果更好。

Seedling-raising experiments for Pinus tabulaeformis were conducted by adopting different container types and specifications.Growth indexes(the seedling height,ground diameter,main root length &total root length)of the container seedlings for Pinus tabulaeformis after one-year growth were determined.Effect of these indexes on the growth of container seedlings were analyzed.Result shows that the height growth and ground diameter of the seedlings which were treated with hard plastic container are the largest,which reach 15.5 cm & 2.66 mm respectively.The main root of the seedlings which were treated with small black plastic container is the the largest,being 29.8 cm.The largest total length of seedling root system is black plastic container,reaching 740.4 cm.Therefore,it is believed that the hard plastic container is beneficial to the growth of the seedling on the ground,and the black plastic container has optimal effect on the root growth of the container seedling.
