摘要
干热河谷石灰岩地区的立地条件差 ,导致造林成活率低 ,使用白金子抗旱保水剂结合ABT生根粉、地膜覆盖技术应用于墨西哥柏工程造林 ,检测结果 :①显著地提高了造林成活率 ,达 99% ,比对照试验地提高了2 1%~ 2 7% ;②植株生长迅速 ,长势旺盛 ,平均高生长达 116cm ,比对照试验地提高 17 5cm ,与定植时高度相比 ,平均增高 4 1cm ,地径增粗 0 3cm。对比效果明显。该项技术适宜在同类地区的林业工程造林中推广应用。
The undesirable site condition of karst area of dry and hot valley of Yunnan province resulted in the low survivor ratio of afforestation. The afforestation experiment with the aid of moisture holding agent, ABT root_growing powder and film cover were carried out. The experimental results are as the follows: 1) The survival ratio of afforestation attains 99%, which is 21%~27% higher than that of control; 2) The average height growth attains 116 cm, which is 17 5 cm higher than the control, the height and diameter are respectively 41 cm and 0 3 cm higher than the level of fixed planting. This technique can be extended to similar areas in the implementation of afforestation.
