不同培肥措施对土壤养分及玉米产量的影响

Effects of Different Fertilization Treatments on Soil Fertilization and Maize Yield

通过田间试验,研究了不同的土壤培肥措施对土壤养分及玉米产量的影响。结果表明:不同处理土壤养分状况发生了明显的改善,施用农家肥比秸秆还田效果明显,半量比全量效果明显,除了有效磷含量是半量农家肥比全量农家肥含量提高更多。秸秆还田处理玉米有所减产,施用农家肥后产量明显提高,半量秸秆还田+半量农家肥增产效果最为明显。

The 6 trial treatments such as 50% straw return to field, 100% straw return to field, 30 m^3/ha manure apply to field, 60 m^3/ha manure apply to field, 50% straw plus 30 m^3/ha manure apply to field and check（ routine fertilizer） were designed to study the effects of different fertilizer treatments on soil fertilization and maize yield. The results showed that ： among all the treatments, the soil fertilization occurred in a marked improvement, application of manure apply to field than straw return to field, semi-effective than the full amount, but the available phosphorus content was 30 m^3/ha manure apply to field more than 60 m^3/ ha manure apply to field. The treatments of manure application has significantly improved maize yield, though straw return to field reduced the yield, the yield of 50% straw plus 30 m^3/ha manure apply to field was most.
