Study of Soil--Water Conservation Effects and Economic Benefit of Ramie in South Slope Crop Land
The runoff and sediment yield were investigated on nature slop with 25° and planting ramie under nature rainfall events. Planting corn in the slop was as control. There were three treatments, including the first treatment that the ramie was planted in slope for harvest fiber （harvested three times a year）, the see ond treatment for forage（harvested when the plant height was 60 cm ）, and the third treatment for no cutting （don＇t harvest products in the growing season）. The results showed that erosion modulus and average runoff rule followed the order of forage treatment〉corn treatment〉fiber treatment〉not cutting treatment. Eco nomic benefit of harvest fiber plot was 32 040.8 yuan/hm2, no harvest plot economic benefit was 7 466.9 yuan/hm2 , harvest feed plot economic benefit was 15 489.6 yuan/hm2 , corn plot was 19 748 yuan/hm2.
