摘要
为了研究不同时期喷施不同质量浓度的矮壮素对晋黍8号农艺性状和产量的影响,选取了2个喷施时期和6个喷施浓度。结果表明,拔节期的调控效果明显优于抽穗前,随着喷施矮壮素质量浓度的增加,黍子的株高、穗长、节数在逐渐减少,径基粗在逐渐增加,有效分蘖数、穗质量、穗粒质量、千粒质量及产量均是先增加后减少。在拔节期喷施质量浓度为15 g/L或30 g/L的矮壮素,株高的矮化率为12%左右,可增产6%~8%。
In this study, to analyze the effects of CCC on agronomic traits and yield component traits of broomcorn millet Jinshu 8,the paper selected two spraying test periods and six spraying test concentrations. The result indicated that with the increasing of concentrations, the plant height, main spike length and stem node number of millet decreased gradually, diameter base crude increased,the effective tillers per plant, panicle weight, grain weight per panicle, thousand seed weight and yield showed the trend of first rising and then decreasing. In addition, the effect of jointing stage was obviously better than the early heading stage. And the conclusion was that the suitable period was jointing stage, and concentrations were 15 g/L or 30 g/L. The plant height decreased by 12%, the yield increased6%-8%.
