| 摘 要： | 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。

| Abstract: | The yield limiting factors of Zhengdan 958 were studied under 3 planting densities of 6 .0 ＆#215; 104 , 6.7 ＆#215;104 and 7.3 ＆#215;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 ＆#215;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 . |
