| 摘 要： | 把1年生的麻疯树截杆成6种不同的高度．研究其对植株生长的影响。结果表明：不同截杆高度对株高、地径、冠幅和枝长增长量以及萌芽数、成枝率、枝粗、枝下高和不同长度的萌发枝数量都有显著的影响。综合这些指标来看，在实际生产中，把麻疯树幼树截成60或80cm高更为适宜，能使植株生长更快、更健壮，促进更多的侧芽萌发和成枝，并形成更合理的树冠结构。

| Abstract: | The one year old of Jatropha curccas L. cut-off rod into 6 different heights, to research its effect on plant growth. The results show that different cut-off rod height on plant height, diameter, crown area and branch length growth rate and sprout rate, branching rate, branch diameter, under branch height of different length and the number of germination branches all have significant effects. These indicators, in the actual production, the Jatropha curcas L. saplings cut-off rod into 60 cm or 80 cm is more appropriate, can make plants grow faster, more robust, more to promote lateral bud germination and branching, and the formation of crown structure more reasonable. |
