特优3301是福建省农科院生物技术研究所,用野败型不育系龙特浦A与自主选育的强恢复系闽恢3301配组育成的高产、优质、抗病杂交稻新组合,2011年通过海南省农作物品种审定委员会审定,米质较优。2012年早造海南省推广种植1 687hm2,2013年早造推广已达3 447hm2,推广势头强劲。琼海市农业技术推广服务中心承担了海南省种子站下达的“优质稻特优3301丰产示范栽培技术研究”项目,通过对不同土壤状况、施肥水平、播种时间、肥水管理集成等技术研究,并进行了经济效益分析,为全省加快特优3301示范推广提供配套技术。现将丰产示范栽培技术研究总结如下。 Teyou 3301 is a new high-yielding, high-quality and disease-resistant hybrid rice combination developed by Institute of Biotechnology, Fujian Academy of Agricultural Sciences, using a combination of wild-type sterile line Longtepu A and self-selected strong restorer line Minhui 3301 In 2011, it passed the examination of Hainan Crop Variety Approval Committee, and the quality of rice is better. As early as 2012, 1 687hm2 of Hainan Province was promoted and popularized, and 3 447hm2 of promotion was made in 2013. The promotion momentum is strong. Agricultural Technology Extension Service Center of Qionghai City undertook the project of “High-yielding Demonstrative Cultivation Technique of Good Quality and Good Quality Rice 3301” issued by Hainan Seeds Station. Through the research on different soil conditions, fertilization level, sowing time, integrated management of fertilizer and water , And conducted an economic analysis of the province for the province to speed up the model 3301 to provide supporting technology demonstration. Now the demonstration of high yielding cultivation technology research is summarized as follows.
