专用金得乐对夏谷茎秆特性·产量及抗倒性的影响
|
摘要
[目的]专用金得乐对夏谷茎秆特性、产量及抗倒性的影响。[方法]采用大田试验设计,在拔节期对6个夏谷品种分别喷施2 000 mg/kg金得乐,研究其对夏谷茎秆性状及产量性状的影响。[结果]金得乐可以提高夏谷穗粒重和出谷率,对结实率有一定的促进作用,对千粒重影响不大,不同夏谷品种产量增幅为2.23%~15.71%,平均增产270.27 kg/hm2。株高平均降低11.97 cm,降幅5.17%~13.94%,茎杆重心高度平均降低6.5 cm,茎秆4节长度3.47 cm,但不同品种间存在一定差异。穗茎长与CK均缩短,平均缩短0.89 cm。40 cm根重变化不明显。茎秆抗折力增强,增幅为7.86~36.50 g。各处理倒伏系数均不同程度降低,植株抗倒性越强,表明金得乐可有效提高谷子抗倒伏的能力。[结论]该研究对金得乐在夏谷上的生产应用提供参考依据。
[Objective] To research the effects of special growth adjusting agent Jindele on the stem characteristics,yield and lodging resistance of summer foxtail millet. [Method] Field experiments were conducted to study the effects of spraying 2 000 mg/kg special growth adjusting agent Jindele for 6 summer millet varieties on the stem characteristics and yield. [Result] Jindele could increase grain weight and grain yield of summer millet varieties,and had a certain promotion effect on seed setting rate,showed little effects on 1 000-grain weight,and increased the yield of different summer millet varieties from 2. 23% to 15. 71%,with an average increase of 270. 27 kg/hm2. The average decrease of plant height was 11.97 cm,the decrease was between 5.17% and 13.94%,the height of the center of gravity of stem was reduced by6.5 cm,and the length of 4 nodes of stem was 3.47 cm,but there was certain differences among the different varieties. The stem length of panicle was shortened,with an average of 0.89 cm.The changes of 40 cm root weight were not obvious. It increased the folding resistance of stem and increased by 7.86-36.50 g. The lodging coefficient of all treatments decreased in different degrees,and the stronger lodging resistance of plants showed that Jindele could effectively improve lodging resistance of foxtail millet. [Conclusion] This research provided references for the production application of Jindele in foxtail millet.
