摘要
就不同收获时期分蘖去留对饲用甜高粱产量及含糖率的影响进行田间试验,结果表明,饲用甜高粱保留分蘖不同收获时期平均产量126.37t/hm2,较掰除分蘖增产24.5%。随着收获时间的延迟,产量、茎秆含糖率均呈上升状态,收获时期以10月10日最佳,分蘖去留平均产量和茎秆含糖率分别达131.74t/hm2和11.45%；霜冻后产量大幅下降,降幅达25.7%~30.7%。
The field tests for effects of different harvest time and retained tiller on yield and sugar content of forage sweet sorghum were conducted in Hexi Corridor. The results showed that the average yield of forage sweet sorghum with retained tillers was 126.37 t/ha, increased by 24.5% in comparison with that of cutting tiller. Yield and stalk sugar content showed increased with the delayed harvest time, and the best harvest day was in October 10th. The average yield and sugar content in stem of retained tiller were upto 131.74 t/ha and 11.45%, sharp drop and the output was decreased by 25.7%~30.7%after the frost.
