我省地处高寒地区,非常适合黄瓜杂交制种。因此,近两年我们在宾县黄瓜制种基地进行了一代杂交制种技术研究,得出一套较为完整实用的黄瓜杂交制种技术,为今后指导黄瓜一代杂交种种子生产提供理论和实践依据。1 植物特性与适应条件黄瓜采种要求隔离500～1000m,但人工杂交用纸简或金属丝(条)扎花的可以不用隔离。如母本是雌性系,可以采取隔离自然杂交,如母本不是雌性系,可采取药剂用乙稀利200ppm人工杀雄和授粉相结合的方法。黄瓜种子发芽适温为25～30℃,在10℃以下不发芽。黄瓜生长适温17～32℃,因黄瓜雌雄同株,在发育途中分化为雌花、雄花。雌雄花形成且受温度
The province is located in the alpine region, very suitable for hybrid seed production cucumbers. Therefore, in the past two years, we conducted a one-generation hybrid seed production technology in cucumber seed production base of Binxian County and concluded a set of more complete and practical hybrid seed production techniques to provide theoretical and practical basis for the future seed production of cucumber hybrids . 1 Plant Characteristics and Adaptation Conditions cucumber seed mining requirements isolation 500 ~ 1000m, but the artificial hybrid paper or wire (bar) tie flowers can not be isolated. If the mother is a female line, you can take the isolation of natural hybrids, such as the female parent is not a female line, you can take the drug with 200ppm artificial insecticide to kill male and pollination combination method. Cucumber seed germination suitable temperature 25 ~ 30 ℃, below 10 ℃ does not germinate. Cucumber growth temperature of 17 ~ 32 ℃, because the cucumber monoecious, differentiation in the development of female flowers, male flowers. Male and female flowers form and are affected by temperature
