香根草在红壤丘陵的适应性及其保土培肥效益

Suitability of Vetiver on Hilly Krasnozem Area and its Benefit in Soil Preservation and Fertilizer Cultivation

在红壤丘陵坡地上的种植试验表明，香根草具有很强的适应性，适应在丘陵坡地不同肥力的红壤上种植，在条件极其恶劣的剧烈侵蚀地段也能正常生长，其适应性与生物景都明显优于芭茅草等乡土草类。香根草具有良好的水土保持效果，在坡度为５～８度的丘陵坡地种植香根草篱其年径流量减少５０％，比对照减少２倍以上，香根草茎叶还具有较好的培肥增产效果。

The plantation trial on the krasnozem hilly sloping land shows that,vetiver possesses very strong suitability, it is suitable for planting with different fertilizer power.It can also grow normally in violent erosion region in worst conditiou,It″s:suitability and biology an1ount are obviously superior to Manyflower Silvergrass and other local grasses.yetiver possesses good effects with soil and water conservation。Planting vetiver fence on the hilly sloping land with a slope of 5-8 degrees.Cause annual runoff decreases 50%,double that of contrast.The stem and leaves of it bave good results for cultivating fertilizer and raising production.
