| 摘 要： | 为了探明免耕超级稻的应用效益、生长发育规律及配套技术，2006—2008年在广西永福县、田东县、玉州区等13个县（市、区）开展了超级稻免耕对比试验、免耕条件下超级稻与普通稻对比试验、免耕条件下超级稻不同栽培密度和不同施氮水平试验。结果表明：免耕超级稻植株高大、茎秆粗壮、抗倒伏能力强、总颖花量大、穗大粒多、结实率高、产量高，比常耕栽培产量提高7．2％-10．8％；免耕超级稻的最高产量可达12361．5kg/hm^2；6个免耕超级稻百亩示范片平均产量达10746．0kg／hm^2；小区对比试验超级稻比普通稻增产1500kg/hm^2上，增幅达20％以上；超级稻早稻密度为27．0万～30．0万蔸／hm^2，晚稻密度为33．0万蔸/hm^2时，产量达到最大值；超级稻施氮量为纯氮180—210kg／hm^2时，节本增收效果最好。

| Abstract: | In order to know about the applying benefits,growth and development law,and matching cultivation technology for no-tillage super rice,the comparison experiments for no-tillage super rice varieties,super rice and normal rice varieties under no-tillage condition,different cultivated densities and nitrogen application levels for super rice under no-tillage condition were conducted in 13 counties(city or district) including Yongfu,Tiandong,Yuzhou District,etc,in Guangxi in 2006-2008.The results showed that the ... |
