根据2010—2015年两系杂交水稻盐两优888大面积制种实践,提出盐两优888高产制种特点是:在保证制种父母本足穗的基础上争取大穗、提高异交结实率。其高产制种技术是:合理安排播差期,确保花期相遇;培育多蘖壮秧,打好高产基础;合理安排行比,栽足基本苗;科学肥水运筹,培育高产群体;采取综合措施,提高异交结实率;加强病虫防治,确保丰产丰收;加强生产过程管理,确保种子质量。
According to the practice of large-scale seed production of Yanliangyou 888, a two-line hybrid rice from 2010 to 2015, the characteristics of high-yielding seed production of Yanliangyou 888 were as follows: striving for big spike and improving seed-setting rate . The high-yielding seed production techniques are as follows: arranging the sowing period rationally and ensuring the flowering period meet; cultivating the multi-tiller and strong seedling and laying a foundation of high yield; rationally arranging the ratio of rowing and planting seedlings; Improve the rate of outcrossing; strengthen pest control, to ensure high yield and bumper harvest; strengthen the production process management, to ensure the quality of seeds.
