小麦宽空幅冬季培肥的产量表现、经济效益及化肥减施效应研究OACSTPCD
Effects of Winter Fertilization within Wide Bare Land of Wheat Field and Reduction of Chemical Fertilizer Application Rate on Yield and Economic Profits of Wheat
研究了在麦幅(20 cm)相间宽空幅(40 cm)种植模式下冬季增施有机肥配合施用拔节孕穗肥对小麦产量及其构成、经济效益和化肥N偏生产力等的影响。结果表明:在拔节孕穗期施用常规数量(108.0 kg/hm2)化肥氮条件下,冬季施用12.0、18.0和24.0 t/hm2有机肥处理较不培肥对照分别增产小麦13.83%、17.81%和19.03%;小麦单位面积穗数随着冬季培肥量的增多而增加,小麦单位面位穗数和每穗实粒数随着拔节孕穗期化肥氮施用量的减少…查看全部>>
Under the planting pattern of wheat with wide (40 cm) bare land between wheat plant lines (20 cm in width), the authors studied the effects of applying organic fertilizer within the wide bare land in winter and reducing the application rate of chem -ical nitrogen ( N) fertilizer at elongating and booting stages on wheat yield , yield components , economic profits and partial produc-tivity of chemical N.The results showed that:under the condition of conventio…查看全部>>
