适宜茶陵县种植的高粱新品种筛选

Selection of Sorghum Varieties Suitable for Chaling County

为解决茶陵县酿造型高粱品种缺乏、酿造企业优质原料不足的问题,从贵州引入红缨子1号、红茅6号、大红粮等11个高粱新品种在茶陵县进行品种适应性试验。结果表明:红茅6号产量最高,为549.55 kg/667m^2,是平均产量2.33倍;其次为川糯1号,产量为461.15 kg/667m^2,是平均产量的1.95倍;这2个品种具有良好的产量性状和适宜的栽培性状,是高粱增产的优质良种,主要优良性状表现为穗粒数多,植株生长较整齐,生育期、千粒重、抗性都比较适中,适宜在茶陵县大面积推广种植。

In order to solve the shortage of sorghum[Sorghum bicolor(L.)Moench]varieties and high-quality raw materials in brewing enterprises in Chaling County,11 new sorghum varieties were introduced from Guizhou Province for the varietal adaptability experiment.Through field observation,their growth and yield characters were identified,and the sorghum varieties suitable for high-yield brewing and mechanized operation were selected.The results showed that among the 11 varieties,Hongmao No.6 got the highest yield at 8243.25 kg/hm^2,which was 2.33 times the average yield;the second was Chuannuo No.1 which yielded 6917.25 kg/hm^2,was 1.95 times the average yield.Having good yield traits and suitable cultivation traits,Hongmao No.6 and Chuannuo No.1 are good varieties for yield increase of sorghum planting,which are characterized by more grains per ear,uniform plant growth,and moderate growth period,1000-grain weight and resistances,suitable for large-scale planting in Chaling County.
