摘要

对设施内的茶园，造成的影响，白天冰雹发生在第一季，已被彻底检查。观测到的冰雹大小为10-20毫米，持续下降约10分钟，损坏新芽，导致叶片脱落。这种冰雹的破坏程度取决于新芽的形状，而芽重型茶园则有许多叶子掉落。与此同时，直接覆盖茶园，将幼芽伤害率降低到12.2%，而不覆盖茶园的幼芽伤害率为55.6%。此外，由于冰雹的影响，新芽的重量变轻，收获量减少了12%左右。

Damages to New Shoots and Influence on Yields Caused by Hail at the Tea Season of First Crop

The effect to tea garden within the facility, caused by daytime hail which occurred during the season of first crop, has been thoroughly examined. The hails observed were 10-20mm in size and kept falling for approximately 10 minutes, damaging new shoots and causing leaves to fall. Extent of damage made by this hail depended on the shape of new shoots, and while bud weight type tea garden had many leaves fallen. Meanwhile, direct covering tea garden achieved to reduce the damage rate of shoots down to 12.2% in comparison to 55.6% without covering tea garden. Also, weight of new shoots became lighter as the result of hail and the amount of harvest was decreased by around 12%.
