黄瓜是雌雄同株异花授粉作物,昆虫传粉杂交率很高,人工杂交制种无论是在产量上还是在纯度上都有一定的难度。采取加强人工措施,减少自然杂交和人为混杂机率。根据生物学特性改善栽培环境条件。科学认真的抓好隔离区的设置,去杂,尤其父本去杂。化学杀雄诱雌,集中坐瓜节位,减少雄花,授粉做标记,把清除自交瓜作为保纯的一项关键措施。根据黄瓜产量的构成因素突出抓好选地,科学施肥,确保单位面积有效株数,单株坐瓜数,授粉质量,及时防治病虫害,改变中后期的肥水管理,适时收获等重要环节。只有严格科学有效地抓好各项技术措施的落实,才能提高黄瓜人工杂交制种纯度和产量,获得边际效益最大值。
Cucumber is hermaphrodite flower pollination, insect pollination rate is high, artificial hybrid seed production in terms of both yield and purity have a certain degree of difficulty. To take to strengthen the artificial measures to reduce the chance of natural hybrids and artificial mixed. According to biological characteristics to improve the cultivation of environmental conditions. Science and careful do a good job of isolation zone settings, to miscellaneous, especially the father to miscellaneous. Chemical kill male induce female, focus on sit melon node, reduce the male flowers, pollination mark, the clear self-clearing melon as a pure measure of a key. According to the components of cucumber yield, we should pay attention to the selection, scientific fertilization, to ensure the effective number of plants per unit area, the number of plants per plant, pollination quality, timely pest control, change fertilizer and water management in the late period, timely harvest and other important aspects. Only strictly implement the scientific and effective scientific and technical measures to improve the purity and yield of cucumber hybrid seed production, access to the maximum marginal benefit.
