| 摘 要： | 以超高产强筋小麦为试验材料,探讨返青、拔节与孕穗肥施用比例对氮、磷、钾吸收利用、籽粒产量的调节效应。结果表明:拔节期追施氮肥,产量提高,后期施氮有利于磷、钾素吸收效率和运转效率提高。施氮量为300kghm-2条件下,以基肥、拔节肥比例为7∶3较为适宜。

| Abstract: | In order to study effects of nitrogen application rates at regreening,jointing and booting stages on nutrient uptake and yield of wheat,the super-high-yielding of strong gluten wheat was used as experimental materials. The results showed that nitrogen application at jointing stage could increase wheat yield while nitrogen application at booting stage could improve uptake and transportation efficiency of phosphorus and potassium. The optimum dressing ratio was 7:3 when nitrogen usage was 300kg hm-2. |
