摘要:
研究了坡耕地不同利用方式下种植苎麻的水土保持效果。在自然降雨条件下，以25°自然坡面，选种植玉米为对照，研究坡耕地种植苎麻收获纤维（每年收获3次）、饲料（株高60 cm时收获）、不收获（在生长季内不收获产品）三种方式下坡耕地径流和产沙规律。结果表明：各处理间土壤侵蚀模数和平均径流系数变化规律为，饲料用处理>玉米小区（CK）>纤维用处理>不利用处理；经济效益纤维用处理最大为32040.8元/hm2、不利用处理为7 466.9元/hm2、饲料用处理为15489.6元/hm2、玉米处理为19748元/hm2。由此表明，南方坡耕地种植苎麻可以达到水土保持效果，且苎麻不收获方式和收获纤维方式可以有效的防治水土流失。
Abstract:
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 second 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. Economic 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.
