本文在对7001S与制种密切相关的特征特性加以概述的基础上,总结提出7001S配组的组合高产制种的技术措施:以8月15~20日为最佳抽穗扬花期,以此确定父母本适宜播差期,给出70优9号、70优04和70优1514三个组合的播差期表;综合分析了亩产200kg的群体产量结构,提出稳步搭好丰产苗架的三个措施;注意及时防治病虫害;及早预测和早期调整花期的原则和方法,提高异交结实率的关键和适期适量喷施920技术。
Based on the overview of the characteristics of 7001s closely related to seed production, this paper summarized the technical measures of combining high-yielding seed production with 7001S with the best flowering-flowering date from August 15 to August 20, The optimal sowing date is given by the sowing date table of 70 combinations of 9, 70, 04 and 70, 1514.A comprehensive analysis was made on the yield structure of 200 kg per mu and the results showed that three Measures; attention to timely control of pests and diseases; early prediction and early adjustment of flowering principles and methods to improve the rate of outcrossing the key and appropriate amount of spray 920 technology.
