摘要
阐述了浙西山区杂交水稻春制的有利气候条件和不利气候对春制的影响，提出了针对性技术措施，主要是中熟组合春制父本采用塑料大棚统一育秧，确定适宜的父母本播差及播期，及时预测和调节花期。
The impacts of climatic conditions on hybrid rice seed production in spring season in the mountainuos area of western Zhejiang are described,and the relative key techniques are also presented. For medium season combinations, the seedling of their male parents should be raised under plastic awning; the seeding dates and the intervals between male and female parents should be reasonable; the flowering time should be forecast and controlled; the fertilizer and water should be managed reasonably.
