杂交水稻集约化制种作为一种新型的制种组织方式正在全国各地逐步推广应用。在制种生产过程中,为规避风险、提高产量、降低成本,制种技术方案和技术措施都有较大改变。文章就集约化制种生产技术在总结多年经验教训的基础上就各环节做出了初步总结,形成了以“大开厢—母本直播—化学除草—机器授粉—机械收割—种子烘干”为主线的杂交水稻集约化制种配套技术,以期对大户承包经营或公司流转土地从事集约化制种生产提供参考。 Intensive hybrid seed production of hybrid rice is being popularized and applied gradually throughout the country as a new seed production organization. In the seed production process, in order to avoid risks, increase production and reduce costs, seed production technology programs and technical measures have greatly changed. The article summarizes many years of experience and lessons learned on the basis of summing up the production of technology based on the various links made a preliminary summary of the formation of a “open box - the mother of live - chemical weeding - machine pollination - mechanical harvesting - seed drying ”As the main line of hybrid rice seed production matching technology, with a view to large contracting or transfer of land companies engaged in intensive seed production for reference.
