摘要
在不同施肥水平下 ,小麦用生物菌肥拌种可增加 级分蘖数量 ,提高分蘖质量 ,并可显著提高植株主要器官干物质积累量 ,增加绿叶面积和成穗数 ,对穗粒数和粒重影响不大 ,增产 6.0 % ,在化肥用量减少2 5 %情况下 ,生物菌肥拌种的产量与常量化肥处理间产量差异不显著 ;不用化肥 ,仅用生物菌肥拌种 ,小麦减产 2 2 %。
It is obvious to promote winter wheat tiller and increase class I tiller number and raise tiller quality of microbial fertilizer seed dressing with different fertilizer level. It is obvious increasing main organ dry matter and green leaves areas and ear number but it is no effect on ear grains and grain weight. The yield increased 6.0 per cent by using microbial fertilizer seed dressing. There are no obvious different between microbial fertilizer seed dressing and usually fertilizer under reduce fertilizer 25 per cent. The wheat yield is reduced 22 per cent when only using microbial fertilizer seed dressing and no fertilizer was used.
