Abstract:
In order to ascertain the growth characteristics and benefits of soil and water conservation of several herbaceous plant in the Gneiss Mountainous Region in Pingshan County，the slope of freshly plowed land in Xiayu Village was chosen as experimental field，two sowing patterns were used to reconstruct vegetation,single-sowing pattern and compound-sowing pattern.The results showed that seed germination time of Pennisetum sinese was the shortest，which was only 3 days；the next one was Cosmos bipinnata；Poa annua was the longest.After sowing for 15 days，the seedling average height of Pennisetum sinese was the highest (10.89 cm)；the next one was Cosmos bipinnata (about 8.88 cm)；the shortest was Trifolium repens (only 0.67 cm).The vegetation coverage of Cosmos bipinnata was the highest，which was about 56.9%；and those of Pennisetum sinese，Cosmos bipinnata+Medicago sativa +Pennisetum sinese，Cosmos bipinnata +Medicago sativa+Trifolium repens were 45.7%,36.1%,34.4% respectively.The soil erosion modulus and runoff coefficient of Pennisetum sinese respectively were 6.60 t?km-2，14.85% and its benefits of soil and water conservation was the best；the soil erosion modulus of Cosmos bipinnata+Medicago sativa+Trifolium repens and Cosmos bipinnata were respectively 11.13 t?km-2，12.70 t?km-2 and the runoff coefficient of them were 19.69%，21.34% respectively.So the erosion intensity of these two kinds of sowing patterns were both medium erosion.The best sowing pattern was mixing the seeds of Cosmos bipinnata，Pennisetum sinese，Medicago sativa and Trifolium repens together before sowing so as to promote soil and water conservation benefits.
