| 摘 要： | 增施磷肥对看麦娘的促进作用大于对小平的促进。，磷肥施用过多，提高看麦娘对养分的竞争能力，加重对小麦的危害。对供试田块施用６０ｋｇ／ｈｍ＾２Ｐ２Ｏ５，能满足小麦丰产的磷营养要求，边际产量最高，而看麦娘的边际产量最低。

| Abstract: | Under field experiment condition, effects of application rate of phosphate fertilizer on the relationship of wheat and shortawn foxtail were studied. During the winter to jointing stage of wheat, the increasing intensity of the shortawn foxtail bio-yield was stronger than the wheat, and then the later growth of wheat was retarded by it. The rate of 60 kg/hm2 P2O5 for the experiment field was sufficient because of the highest marginal yield of wheat and the lowest of the shortawn foxtail |
