The Effect of Premium Pasture-sweet Pea on Holding Soil and Water
The area of Loess Plateau lacks of vegetation, the water and soil erosion and sand blown by wind are very serious, environment is deteriorating increasingly. At the same time, a great deal of sediment from the up and middle reaches of the Yellow River enter into the Yellow River. As a result, the river bed in the main stream of the lower reaches the Yellow River increases year by year. So we should introduce into some premium vegetable to keep water and soil immediately. Xifeng experimental station for soil and water conservation fetched in sweet pea from middle west of American, according to the theory of climate similar and take the experience for 8 years (1998~2005). They draw a conclusion that Sweet Pea is suitable for ravine of Loess Plateau, and root is deep, as well as, it can cover with most area. Therefore, it can be the premium pasture to conserve water and soil, reduce sediment enter into the Yellow River, improve the condition of environment and the breed of natural pasture.
