豫东地区能源型甘薯品种的筛选

Screening of Energy-based Sweet Potato Varieties in East Henan

为选育适合豫东地区自然条件的高产高淀粉型甘薯品种,在河南省商丘市进行了生产试验,并测定各品种的鲜薯产量、薯干产量、干物质量、淀粉率及主要病虫害抗性。结果表明:徐薯22、商薯19和金玉3种能源生产专用型甘薯品种能更好地适应当地条件,其淀粉含量比当地主栽品种豫薯9号提高10%左右,产量提高5%～10%。大力发展能源型甘薯种植能使农民增收,使用生物质能源可有效减轻大气污染,经济效益、社会效益和生态效益明显。

The fresh yield,dry sweet potato yield,dry matter amount,starch ratio and resistance to major disease and pest of 11 tested sweet potato varieties were determined by the productive test to screen sweet potato varieties with high yield and high starch content for the ecological condition of East Henan.The results showed that the Xushu 22,Shangshu 19 and Jinyu varieties could adapt to local ecological condition better and their starch content and yield were 10% and 5%~10% higher than Yushu 9（CK） respectively.Planting energy-based sweet potato varieties could enhance farmer＇s income.And the biomass energy could reduce air pollution and make significant economic,social and ecological benefit.
