小麦拔节期喷施两种化调剂控高防倒效果
Effect of Spraying Two Kinds of Chemical Regulators on Height Control and Lodging Prevention in Wheat Jointing Stage
摘要:
为研明化调剂烯效唑、矮壮丰对旺长小麦的化学调控效果及其最佳使用结点、使用剂量，进行了其在小麦拔节期的应用效果试验。结果表明，小麦拔节期喷施烯效唑40~60 ml/亩或矮壮丰70~100 ml/亩，能够控制株高，优化群体、健壮个体，减少倒伏风险，并一定程度上提高小麦产量。烯效唑亩用量60 ml/亩拔节期喷施效果最好，能够达到较好的控高防倒增产的效果。
Abstract:
In order to verify the effect of Uniconazole and Chunquan Cycocel on chemical regulation of vigorous and long wheat, the application effect test was carried out. The results showed that spraying Uniconazole 40 - 60 ml/mu or Chunquan Cycocel 70 - 100 ml/Mu at jointing stage could control plant height, optimize population and healthy individuals, reduce lodging risk and increase wheat yield to a certain extent. The effect of Uniconazole 60 ml/Mu at jointing stage was the best, which could control height, prevent lodging and increase yield.
