摘要
试验分析了测土配方施肥对杂交玉米农艺性状、产量性状及其生物产量和经济产量的影响,同时分析了氮磷钾三要素各配方施肥处理的肥料效应,为当地的农业生产施肥提供科学依据。结果表明:各配方施肥处理杂交玉米的农艺性状和产量均有所提高;氮磷钾三要素对单穗重影响最大,其次为穗粒数、穗位和株高,对穗粗、穗行数、穗长和百粒重的影响相对较小;14个处理中以N2P2K2处理的玉米产量最高,每667 m2产量达661.3 kg;经济效益以N2P1K2处理最好,单位纯收入最高的是N2P1K1处理,达1 261.09元;产投比最高的是N1P2K1处理,达到2.17倍。
In order to provide scientific instructions for the local agricultural production of hybrid corn,the affection of fertilizer on agronomic characters,yield-related traits,mass and economical production of hybrid corn were analyzed in the ＂3414＂ experiment.Meanwhile,the fertilizer effects of N,P,K were also analyzed in this experiment.The results showed that,the agronomic characters and yield-related traits of 13 treats were more or less higher than that of the control group;the magnitude effect of the three elements of fertilizer（N,P,K） on the traits in turn were weight per ear,grain number per ear,ear height,plant height,nevertheless,that on diameter of ear,rows per ear,ear length and 100-grain weight were comparatively small.Among the 14 treats,treat sixth（N2P2K2） got the highest yield,which was 661.3 kg per 667m2.Treat fifth（N2P1K2） possessed the best economical benefit.The highest net income lied in treat fourteenth（N2P1K1）,which was 1 261.09 yuan,and the biggest ratio of output to input was 2.17,which existed in treat thirteenth（N1P2K1）.
