我国每年黄瓜需种量达60万kg，杂交种需种量占30％－40％，种子的产量、质量直接影响到农户的利益。常规品种主要靠昆虫自然授粉，因而种子的产量与当年的气候、昆虫、隔离区等条件息息相关。杂交种的制种（除雌性系制种）主要靠人工授粉，种子的产量不仅与授粉技术、气候条件
In our country, the annual cucumber needs to be 600,000 kg and the hybrids account for 30-40% of the total. The output and quality of the seeds directly affect the interests of farmers. Conventional varieties rely mainly on insect natural pollination, so the seed yield and current climate, insects, isolation zone and other conditions are closely related. Hybrid seed production (except for female lines) mainly by artificial pollination, seed yield not only with pollination technology, climatic conditions
