不同玉米品种对麦秸覆盖引起的生化他感作用的差异性分析

In this paper pot experiment was conducted on the allelopathic effect of wheat straw water extract and wheat straw mulching on corn seed germination and early growth and development among different corn varieties.The results show that there is significat variation among different corn varieties in enduring allelopathic effect of wheat straw mulching.When the most endurable corn varieties are selected for growing under wheat straw mulching condition,the negative allelopathic effect on corn growth and development could be avoided.
