| 摘 要： | 以易倒伏水稻品种垦稻12为试验材料,设置600g/hm2、900g/hm2、1200g/hm2、1500g/hm24个调节剂水平,研究不同调节剂用量对水稻抗倒伏能力及产量性状的影响。结果表明:调节剂处理水稻的株高降低,节伸长受到抑制,茎秆抗折力增加,弯曲力矩减小,倒伏指数减小。与对照相比,化学调控有效降低了水稻倒伏的发生几率。调节剂处理可促进水稻分蘖,收获穗数的增加补偿了千粒重降低的负效应,在600g/hm2处理水平下,寒地水稻收获穗数增加明显,结实率有增加趋势,水稻产量比对照增加显著。900g/hm2、1200g/hm2处理水平下水稻产量增加不明显,在1500g/hm2处理水平下产量比对照降低。 |

| Abstract: | Effects of chemical regulation on lodging and yield at four chemical regulating levels were studied using Kendao12 as materials.The results showed that the plant height was shortened,elongation of stem was restrained,the breaking-resistant strength of stem was increased,and bending moment and lodging index was decreased by chemical regulation.Compared with the control,chemical control effectively reduced the probability of the occurrence of rice lodging.The increase of panicle number harvested compensated n... |
