摘 要:采用半量秸秆还田、全量秸秆还田、农家肥30 m3/hm2、农家肥60 m3/hm2、半量秸秆还田+农家肥30m3/hm2和当地常规施肥方式(对照)处理,研究不同培肥措施对玉米生长发育及产量的影响。结果表明,株高、植株基部周长、单株叶面积和棒三叶叶面积均以农家肥60 m3/hm2处理最高;出苗率以农家肥30 m3/hm2处理最高,全量秸秆还田处理最低;经济产量增加幅度依次为半量秸秆还田+农家肥30 m3/hm2>农家肥60 m3/hm2>农家肥30 m3/hm2>半量秸秆还田>全量秸秆还田。Six trial treatments such as 50% straw return to field, 100% straw return to field, 30 m3/ha manureapply to field, 60 m3/ha manure apply to field, 50% straw plus 30 m3/ha manure apply to field and check(routine fertilizer) were designed to study the effects of different fertilizer treatments on growth, development and yield of maize. The results showed that among all the treatments, the plant height, plant base perimeter, leaves area per plant and three ear leaves area in 60 m3/ha manure apply to field was the highest; but the highest emergence rate was in 30 m3/ha manure apply to field, the 100% straw return to field was the lowest. The grain yield increase followed by 50% straw plus 30 m3/ha manure apply to field〉 60 m3/ha manure apply to field〉 30 m3/ha manure apply to field〉 50% straw return to field 〉 100% straw return to field.
