| 摘 要： | 研究了川西低山丘陵区坡耕地上不同密度巨桉林下几种牧草的高生长、产量动态变化。结果表明:牛鞭草的株高、产量都居于首位,是巨桉 林草模式中的优选草种。在坡耕地退耕还林初期林木郁闭成林前,在幼林地内种植牛鞭草,应控制好林分的密度,而巨桉的造林密度控制在883~1111株.hm-2最为适宜。

| Abstract: | The experiments were made on the dynamics of the height among growth forests and yield of four forage species under Eucalyputs grandis forests with different density in hilly regions of western Sichuan.The results have indicated that the height and yield of Hemarthria compressa are the highest those of other three forage species,and Eucalyptus grandis Hemarthria compressa model is the best one for converting slope farmland into forest in west Sichuan Province.In the initial stage the optimum planting density of Eucalyptus grandis should be controlled between 883and 1111 individuals per hectare. |
