摘　　要：为探讨小麦高产新技术宽幅精量播种的增产效果，采用大区对比，随机排列，进行了不同播种方式效果试验．两年研究结果显示：不同播量中以宽幅精播的小麦个体发育好、群体动态适宜、产量水平高，其中以7．0kg／667m2播种量的产量最高，较常规精播增产12．9％，大田示范较常规精播增产8．7％-13．6％．For the sake of probe into yield-increasing effect of high yield new technology-wide breadth precision seeding,adoption the large area comparative experiments,random arrangement,has studied the effect of different sowing ways experiment.Two-year study results shows that different sowing norm wheat ontogenetic population dynamics,yield of the wheat wide breadth precision seeding was better than the conventional precision seeding.The yield sowing norm 7.0 kg/667m2 was the highest,its yield increased by 12.9% more.The yield increased by 8.7%- 13.6% in the representative fields than conventional precision sowing.
