4个木薯品种在云南不同干热河谷的区域试验

A Regional Experiment on Four Varieties of Cassava in Different Dry-hot Valleys in Yunnan

对4个木薯品种——华南7号、KU50、南美1号、华南205在云南省元谋县、保山市隆阳区和永德县3个点进行区域试验。结果表明,南美1号在隆阳区试验点的鲜薯产量最高(59548.5kg/hm2),KU50在永德县鲜薯产量最低(32 812.5 kg/hm2);KU50在元谋县的干物质含量最高(47.6%),在隆阳区试验点最低(27.3%);华南205在永德县的淀粉含量最高(41.7%),在隆阳区试验点最低(27.2%)。综合3个主要指标,KU50在元谋县干热区适应性最好,可作为该地区推广种植品种;KU50和南美1号可作为隆阳区的推广种植品种;华南205可在永德县推广种植。

A regional experiment was carried out in Yuanmou,Baoshan,Yongde for four varieties of Cassava-SC7,KU50,South America No1 and SC205.It showed that South America No1 had high yield in Baoshan.Its yield reached 59 548.5 kg/hm 2.The lowest yield was KU50 in Yongde.Its yield was 32 812.5 kg/hm 2.The highest dry matter content was KU50 in Yuanmou approached 47.6%.The lowest dry matter content was KU50 in Baoshan,27.3%.The highest starch content was SC205 in Yongde approached 41.7%.The lowest starch content was SC205 in Baoshan,27.2%.According to the 3 indexes,yield,dry matter content and starch content,KU50 was adapted in dry-hot region like Yuanmou.It could be popularized in this region.The recommend varieties in Baoshan were KU50,South America No1.In Yongde,SC205 was suitable to plant.
