| 摘 要： | 2014—2015年,通过盆栽试验和田间小区试验测定了缩节胺对胡麻株高和产量性状的影响。结果表明,喷施缩节胺可使胡麻植株高度降低2.59~13.74 cm,一级分枝缩短1.25~4.45 cm,有效缩小单株株冠面积,且对正常生长发育和其他农艺性状以及种子产量影响不大,提高胡麻抗倒伏能力效果显著。缩节胺的最佳施用期是胡麻现蕾期,最佳施用浓度是60 000~90 000 mg/kg。

| Abstract: | Based on pot experiment and field experiment, we measured influence of dimethyl piperidinium chloride (DPC) on plant height and yield traits of oil-flax during 2014—2015. The result shows that spraying DPC can lower plant height about 2.59-13.74 cm, shorten the first grade branch 1.25-4.45 cm, shorten canopy area, but this does not affect growth, development, agronomic traits and yield of oil-flax. The lodging resistance capability is strengthened obviously. The optimum amount applied is 6×104 mg/kg~9×104 mg/kg, and applied in squaring period. |
