为了寻找适合云南省玉溪市生态条件的高粱新品种 ,于 1 993～ 1 997年对“大米小麦旱高粱”进行了引种观察、品比试验和不同海拔条件下的适应性试验等研究。结果表明 :“大米小麦旱高粱”适应性较广 ,在海拔 40 0～ 2 3 0 0m范围内都能种植 ,产量以海拔 1 1 5 0～ 1 6 4 0m范围内最高 ;在同等条件下 ,比对照品种本地红高粱增产 1 1 2 .9%。
In order to find new varieties of sorghum suitable for the ecological conditions in Yuxi, Yunnan Province, the introduction of rice sorghum (Sorghum bicolor L.) from 1993 to 1997 was introduced, and the ratio test and adaptability test at different altitudes were conducted. The results showed that “wheat and wheat sorghum” were widely adaptable and could be planted in the range of elevation of 40 0 ~ 2300 m, with the highest yield in the range of 1150 ~ 1640 m. Under the same conditions, Than the control varieties of local red sorghum yield 112.29%.
