摘要:
大粒蚕豆"大朋一寸"产量、农艺性状及抗性鉴定结果表明,该品种籽粒翠绿、口感香甜、丰产稳产、适应性广.采用正交试验,探讨"大朋一寸"花荚期叶面喷施不同微量元素和打顶、疏枝、疏花等田间调控技术对青荚产量的影响,结果表明,喷施微量元素B或B+Mo、打顶、疏枝、疏花等调控技术均能显著提高青荚产量,增产效应大小为:打顶喷施微量元素B+Mo疏枝疏花喷施微量元素B.打顶比不打顶增产13.38%、喷施微量元素B+Mo比不喷施的增产7.87%、疏枝比不疏枝增产5.06%、疏花比不疏花增产4.16%、喷施微量元素B比不喷施的增产3.43%.综合应用喷施微量元素和打顶、疏枝、疏花等田间调控技术,青荚产量可增产28.62%以上.

Abstract:
Large seed broad bean-'Dapengyicun' is green grain,sweet,high and stable yield and wide adaptability.Orthogonal design was used to study on the fresh pods yield of Dapengyicun' by foliage spray of different trace elements,topping,branch thinning and flower thinning during its flowering and podding stage.The results showed that spraying of trace elements B or B+Mo,topping,branch thinning,flower thinning could increase the fresh pods yield significantly,and the order of the yield is topping spraying of B+Mo branch thinning flower thinning spraying of B.The yield of topping is 13.38% higher than the no-topping,the yield of spraying of B+Mo is 7.87% higher than the no-spraying,the yield of branch thinning is 5.06% higher than the no-branch-thinning,the yield of flower thinning is 4.16% higher than the no-flower-thinning,the yield of spraying of B is 3.43% higher than the no-spraying.Comprehensive application of regulation technology such as trace elements spraying,topping,branch thinning and flower thinning,can increase the fresh pods yield beyond 28.62%.
