Abstract:In view of the environment character of the soil and content of the soil organic carbon, 278 species of grass and frutex were introduced from abroad and China, Some were selected by applied production and plantation benefit investigations. The results showed that: In the arid-hot valleys of Yuanmou the selected species showed the characteristics of fast growth and high yield (38 227.00 kg/hm2), high nutrition value (CP% content of leguminous grass and frutex were 22.47%), as well as the strong adversity resistance to high air temperature and arid climate (soil humidity was 3.4%). The selected species not only effectively meliorated soil and increased fertility, but also improved small environment weather. Biography: LONG Huiying (1965–), female, Associate researcher, research direction: the study and utilization of the agricultural resources in the hot area and ecological restoration technique demonstration in the arid-hot valleys.
Keywords:arid-hot valleys  grass and frutex  species selection  plantation benefit
