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。
Using half amount of straw returning to field, full straw returning, farmyard manure of 30 m3 / hm2, farmyard manure of 60 m3 / hm2, half amount of straw returning farmland manure of 30m3 / hm2 and local routine fertilization (control) Effects on Growth and Yield of Maize. The results showed that the height of plant, perimeter of plant, leaf area per plant and leaf area of stem and leaf were the highest with 60 m3 / hm2 of peasant fertilizer. The germination rate was highest with peasant fertilizer of 30 m3 / hm2 and the lowest ; The increase of economic yield followed by half amount of straw returning + farmer fertilizer 30 m3 / hm2> farmer fertilizer 60 m3 / hm2> farmer fertilizer 30 m3 / hm2> half amount of straw returning> full amount of straw returning to the field.
