山桐子石漠化山地造林试验

Preliminary study on afforestation in rock desertification mountain of Idesia polycarpa

在重庆中梁山石漠化山地进行山桐子造林试验,定量研究其成活及幼林生长情况,结果表明:栽培于不同坡位的山桐子其成活率、生长量差异明显,其中坡位中部的山桐子成活率最高,生长情况最好,上部和下部坡位其次。且夏季高温伏旱天气对成活率和生长量均有明显影响。

An afforestation in rock desertification Mountain of ldesiapolycarpa was experimented in Chongqing Zhongliang mountain. The survival rate and mass growth were researched quantificationally. The results showed that disparity of records mentioned previously among different slope positions of the mountain are distinct. The survival rate and mass growth of Idesia polycarpa trees in the middle slope is the best followed by that in upper and lower slope. Furthermore, high temperature and summer drought had evidently dropped the survival rate and mass growth.
