• 落叶

  The discipline was not changed under lime and EM treatment. (2) Soil fauna had staged feature during defoliation decomposition in treated plots.

  处理条件下土壤动物在落叶分解过程中仍具有阶段性特征,且各类群集聚时间有所差异。

• 脱叶

  Chemical defoliation can have most of the leaves abscised quickly before harvesting time, thereby improving operation efficiency of mechanical harvest and decreasing percentage of trash content in raw cotton.

  化学脱叶是在收获前促使棉株的绝大部分叶片尽快脱落的一种技术,以提高机械采收的作业效率并降低子棉的含杂率。
