Characteristics and Mechanical Transplanting Effects of the Seedling Raising by Printed Seed-sticking of Parents in Hybrid Rice Seed Production
摘要
Abstract
Using hybrid rice parental lines Jing 4155S,Yixiang 1A,Quan 9311A,Huazhan,R1607,R534,etc.as materials,the treatments of different glue spot spacings of seed-sticking by printing and different seedling ages for mechanical transplanting were designed to investigate the seed-sticked quality by printing,seed utilization rate,seedling quality,mechanical transplanting effect and the characteristics of growth and development and panicle-spikelet structure of the parental lines in hybrid rice seed production,with the traditional wet-nursery seedling raising method as a control.The results showed that the seedling raising method of printed seed-sticking had the advantages of uniform seeding(1.5～1.7 grains per glue spot),flexible seedling age(20～50 d),and mechanical transplanting with water for medium and large seedlings.It was a suitable method for cultivating machine-transplanted seedlings of parental lines in hybrid rice seed production,and it was suitable for different planting schedules in seed production bases and different seeding-interval hybrid combinations in hybrid rice seed production.However,the seedling age of the printed seed-sticking seedling raising method has a great effect on the duration from seeding to heading of the parents,so it is necessary to focus on this effect to ensure the synchronization in flowering period of the machine-transplanted parents in hybrid rice seed production.关键词
