摘要
在大田玉米单作、玉米+马铃薯间作两种种植模式下,按N∶P=1∶1和2∶1两种肥力配比和3个肥力梯度处理进行试验。结果表明,两种种植模式,采用N∶P=1∶1的肥力配比、低肥梯度处理能够满足天池3号玉米的基径、株高、叶片数及最大叶长等农艺性状的生长要求。不同肥力梯度对玉米产量及千粒重影响明显,表现为特高肥>高肥>低肥,且明显高于对照。采用N∶P=1∶1的肥力配比,在不同肥力梯度条件下,其千粒重和产量均高于N∶P=2∶1的肥力配比。
Under two planting pattern （maize monocuhure, maize intercropping with potato）, two fertilizer ratio（N：P=1：1 and 2：1） and three fertilizer level, the agronomic traits and grain yield of maize variety Tianchi No.3 was studied. The results showed that the fertilizer ratio （N：P=1：1） and low fertilization in two planting pattern could meet the needs of the maize variety Tianchi No.3. The influences of different fertilizer levels to maize grain yield and 1000-grain weight were extremely high fertilization〉 high fertilization〉low fertilization 〉CK. In different fertilizer level condition, the maize grain yield and 1000-grain weight were obviously higher with fertilizer ratio of N：P=1：1 than with fertilizer ratio of N：P=2：1.
