杂交水稻制种中利用农用无人机喷施赤霉素技术研究
Study about the Techniques of Gibberellin Sprayed by Agricultural Unmanned Aerial Vehicle in Hybrid Rice Seed Production
摘要
Abstract
Three hybrid combinations,Y58S × R900,H638S × R1813 and Fengyuan A × Huazhan,were used as materials with machine-transplanting,artificial transplanting and mechanical direct seeding,different doses of gibberellin were sprayed at different heading stages of female parents by using single-rotor electro-dynamic-force agricultural unmanned aerial vehicles to explore the effects of gibberellin in the hybrid rice seed production.The results showed that the gibberellin effect on Y58S with artificial transplanting was the best,when the earing rates was 5％-35％,and the gibberellin dose was 480 g/hm2.When the earing rates of Y58S by machine-transplanted were in the range of 5％-45％,the gibberellin effects were good with three spraying doses,which the package neck rate was low than 1％ and the total panicle exsertion rate was over 80％.When earing rates of H638S were in the range of 5％-45％,the gibberellin effects were good with three spraying dosages by machine-transplanted and mechanical direct seeding.When the earing rates of Fengyuan A were in the range of 10％-20％,the best results occurred at the dose of gibberellin 570 g/hm2 and by machine-transplanted.The gibberellin effects on Fengyuan A were poor with all the three spraying dosages by mechanical direct seeding,which the package neck rate was over 1％ and the total panicle exsertion rate was under 80％.In conclusion,spraying gibberellin on female parent by agricultural unmanned aerial vehicles could widely used in hybrid rice seed production.关键词
