不同播种量对稻套麦群体质量及产量的影响

Effect of the Different Sowing Amounts on the Wheat Population Quality and Yield in Interplanting Wheat in Paddy

通过研究淮北地区小麦不同播种量对稻田套小麦群体质量及产量的影响,得出该地区地力上等田,稻田套小麦的适宜播种量为225kg/hm2、在此播种条件下易获得较好的群体质量和较高的产量。播量过低,基本苗少,成穗数不足,不易获得高产;播量过大,群体质量下降,也不易获得高产。

The result shows that in Huaibei region, producing wheat in height fertility field, wheat sowing amounts should be at the level of 225kg/hm2 by studying the effect of the different sowing amounts on the wheat population quality and yield in interplanting wheat in paddy. At the level it was easy to get high population quality and yield. At a low level basic seedlings and mature spike number were lacking. It was difficult to gain high yield. At a high level the wheat population quality descended. It was hard to obtain good yield.
