摘　　要：以持续进行了28年的长期定位试验为基础,研究了不同施肥条件对夏玉米生长发育的影响。结果表明,施肥对夏玉米不同时期生长发育指标影响明显,夏玉米高有机肥、高氮肥配施处理灌浆期平均株高、开花期茎粗、单株叶面积最高。28 years locatal experiment was conducted to study the effects of long-term fertilization on the growth and development index of summer maize and the results showed： different treatments of fertilization had significant effects on growth and development index of summer maize. The average plant height in filling stage resulted from the fertilization of high -rate organic fertilizers in combination with high -rate nitrogenous fertilizers. The stem diameter in blooming stage resulted from the fertilization of high -rate organic fertilizers in combinaticm with high-rate nitrogenous fertilizer.The fertilization of high-rate organic fertilizers in combination with high-rate nitrogenous fertilizers significantly increased the teaf areas of single plant in every stage and the leaf area of single plant was 9 888.0 cm^-2, which iucreased bv 10.6 % compared with those of CK.
