摘　　要：通过有机、无机肥料配合施用,研究不同生育期玉米形态生理生化指标,分析其对玉米生长发育及产量的影响。结果表明,增施有机肥的条件下,化肥用量的增加对玉米生长发育有促进作用,M15+F3(有机肥鸡粪15 m3/hm2+N 200 kg/hm2、P2O5100 kg/hm2)处理茎秆强度较对照高40.8%,达到显著水平;叶面积最大,净光合速率最高,干物重积累较快;M15+F3处理获得最高产量,较对照提高11.19%。各处理间的叶绿素含量差异不显著,随生育进程推移呈先增加后降低的趋势变化。The effects of manure and fertilizer application on growth and yield of maize were studied. The re- suits showed that, based on manure application, fertilizer application promoted maize growth. The treatment of M 15＋ 174 stem strength was higher than CK with 40.8%, reached significant level; M15＋F3 leaf area was the largest and the photosynthetic rate was the highest. It＇ s dry matter accumulation was faster and it＇ s more than CK 4.25 g average per square meter per day; M15＋F3 treatment got maximum yield, it＇s higher than CK with 11.19%. The chlorophyll content was not significant among all treatments, but the growth tended to increase and decrease after that.
