本研究从源库理论角度分析了郑单958在6．0、6．7、7．3万株/hm23个种植密度水平下的自身产量限制因子，指出黄淮海地区在6．75万株/hm2或者更高种植密度水平上进一步改良郑单958是有意义的；在本试验所设的密度水平上，郑单958自身产量限制因子均为源不足。

The yield limiting factors of Zhengdan 958 were studied under 3 planting densities of 6 .0 × 104 , 6.7 ×104 and 7.3 ×104 plants per hectare using source -sink theory.The results showed that it was pos-sible to further improve Zhengdan 958 under the density of 6.75 ×104 plants per hectare or more in Yellow and Huai River valley .The yield limiting factors of Zhengdan 958 under the studied planting densities were all deficiency of source .
