摘　　要：1999～ 2 0 0 0年华安 3号在粤东作双季稻种植成功。作早稻单产 9.942～ 10 .38t/hm2 ,比对照增产 10 .45 %～ 18.80 % ;作晚稻单产 9.5 48t/hm2 ,比汕优 6 3增产 6 .15 %。华安 3号的高产栽培技术 ,一是争足穗攻大穗 ;二是控制后期氮肥防倒伏 ;三是科学用水 ,及时防病治虫。The study showed that the average yield of Hua'an 3 was 9.548(late rice)-9.964(early rice)t/hm 2 in the east of Guandong.It increased production by 6.15 %～11.3% compared with the check (Shanyou 63 et al).The keys of getting high yield were to cultivate strong seedlings,apply N fertilizer in early period for multi-panicles and panicle weight, control irrigation,and provide timely plant protection.
