摘　　要：以两系杂交稻Y两优900为供试品种,采用50kHz超声波干法处理种子1min,以种子不进行超声波处理作对照,采用常规催芽播种、钵苗育秧和常规栽培管理,研究超声波干法处理对水稻种子发芽出苗及产量的影响。试验结果表明:Y两优900种子经50kHz超声波干法处理1min后比对照发芽势增强,发芽率提高5.89个百分点,秧苗素质提高,每667m2有效穗数、成穗率、每穗总粒数、每穗实粒数、结实率、千粒重等主要经济性状均比对照高,比对照增产9.13%,每667m2净增收143.6元。With two-line hybrid rice variety Y Liangyou 900 as the tested material,effects of ultrasonic dry treatment on seed germination,seedling emergence and yield of rice were studied by treating rice seeds with 50 kHz ultrasonic for 1 min,and then conventional germination sowing,seedling raising in pots and conventional cultivation management,the control rice seeds did not receive the ultrasonic dry treatment.The results showed that the germination potential of treated Y Liangyou 900 seeds was enhanced compared with the control,and the germination rate increased by 5.89 percentage points,and the quality of the seedlings was increased.Meanwhile,The main economic traits of the treatment,such as the number of effective panicles per 667 m2,earbearing tiller percentage,the total grain per panicle,the effective grains per panicle,the seed setting rate and the 1000-grain weight,were higher than the control,the yield of which increased by 9.13%,and the net income increase by 143.6 yuan RMB per 667 m2,compared to the control.
