摘要/Abstract

摘要： 为了揭示氮、磷、钾不同配比的BB肥在小麦产量建成中的作用规律,2013年在枣庄市市中区税郭镇东南村,采用随机区组试验设计,分氮、磷、钾5个不同配比研究了BB肥对小麦产量的影响,揭示了不同配比BB肥作用下小麦叶面积系数的变化规律。结果表明:基施BB肥的处理能引起小麦叶面积系数的提高,并能改善小麦的产量。以1hm2土地基施375kg氮、165kgP2O5和150kgK2O时作用效果最佳,增产幅度达16.9%。

Abstract: Aiming to uncover the principle of different ratio of BB fertilizer about N,P2O5,K2O in the wheat yield,using randomized block design,the effects of BB fertilizer under 5 different ratio were researched in the village of Dongnan,Shuiguo town,central district of Zaozhuang city in 2013.Moreover,the changes of leaf area index under the action of BB fertilizer were discussed.The results showed that the BB fertilizer can improve leaf area index of wheat as base fertilizer and the yield of wheat was increased.It had the best effect according to 375 kg/hm2 N,165 kg/hm2 P2O5 and 150 kg/hm2 K2O,and the range of increased yield reached to 16.9%.
