不同容器规格对栓皮栎苗木生长的初期影响

The Effect of Different Container Sizes on the Early Stage of the Quecrus variabilis Seedling Growth

试验采用单因素完全随机区组设计,研究不同容器规格对栓皮栎育苗和造林后生长状况的影响,结果表明:对栓皮栎育苗和造林的生长状况有较大影响的处理为A处理。具体指标为高度36cm,口径6.4cm,体积983cm3,呈深圆锥形体。该容器规格下苗木发育最佳,苗高地径分别达到47.9,4.23cm,且在造林后表现良好,成活率达到100%,苗高地径分别达到63.5,6.64cm,在光合特征方面也收到较好效果。因此,A处理是栓皮栎育苗和造林的最好选择,也就是容器体积和深度的增加可以提高苗木的生长状况。

To study the effect of different container sizes on the seedling raising of Quecrus variabilis and growth condition after afforestation,we use single factor randomized block design completely. The results suggest that container size A has greater influence on the seedling raising of Quecrus variabilis and growth condition after afforestation. The specific indicators of A are as follows： height is 36 cm,diameter is 6. 4cm,volume is 983 cm3,the form is deep cone. The seedling growth is the best in container size A. The height and ground diameter of Quecrus variabilis in the container are 47. 9cm and 4. 23 cm. The Quecrus variabilis has good performance after afforestation and its survival rate reaches 100%. After afforestation the height and ground diameter of Quecrus variabilis are 63. 5cm and 6. 64 cm,and it performs well on photosynthetic characteristics. Therefore,treatment A is the best choice for seedling raising and afforestation of Quecrus variabilis,in other words,the increase of the container volume and the depth can improve the growth of seedlings.
