摘要
[目的]研究不同品种谷子的鸟害,减轻鸟害对谷子的影响。[方法]测定8个谷子品种的穗重、穗长、穗直径、千粒重、秕粒率等指标,研究早收获对灌浆的影响,比较谷穗总损失与架网成本。[结果]架网成本远高于在不架网情况下谷子正常收获的鸟害损失,并且过早收获造成的谷子减产要高于在不架网情况下谷子正常收获的鸟害损失。[结论]夏播谷子不能早于9月1日收获;通过调节不同品种谷子的播期、收获期及空间隔离,能有效防止鸟害,减少防鸟害成本。
[Objective] Bird damage of different millet varieties was researched, to reduce the bird damage on millet. [ Method ] Panicle weight, panicle length, panicle diameter, 1 000-grain weight, blighted grain rate of 8 millet varieties were measured. The effect of early harvest on grouting was studied,the grain total loss and the net cost were compared. [ Result]The cost of frame net was much higher than the loss of bird damage on millet at normal harvest without frame net. Reduction of millet output caused by early harvest was higher than the loss of bird damage on millet at normal harvest without frame net. [ Conclusion] Summer-sowing millet can not be harvested earlier than Sep. 1. It can effectively prevent the bird damage, reduce the cost of prevention by adjusting sowing date, harvest time and spatial isolation of different millet varieties.
