摘　　要：机插杂交粳稻在麦秸杆全量还田的情况下，研究不同氮肥用量对机插杂交粳稻的产量影响，结果表明：杂粳机插的每667m2施纯氮量在18～20kg之间较为适宜，肥料运筹方法应该是掌握前重、中控、后足。在水浆管理上要应注意以水调气。The effect of different nitrogen level on yield of mechanical transplanting rice under the condition of all wheat straw returning were researched, the result indicated that appropriate pure nitrogen was 18-20 kg/667 m2, fertilizer application should be front-more, middle-controlled and behind- sufficient. It should be use water to adjust gas on water management.
