摘要
通过长期定位试验研究不同施肥结构在黄泥田土壤上对作物产量的影响,筛选出适合当地农业生产的施肥结构。在云南省通海县龚杨村实施11a的定位施肥田间小区试验,研究①不施肥(CK)、②氮磷钾化肥配施(NPK)、③农家肥氮化肥配施(OM+N)、④农家肥氮磷化肥配施(OM+NP)、⑤农家肥氮钾化肥配施(OM+NK)、⑥农家肥氮磷钾化肥配施(OM+NPK)等6种施肥结构对水稻、蚕豆高产、稳产、肥料贡献率和持续性的影响。结果显示:水稻平均产量OM+NP>OM+NPK>NPK>OM+NK>OM+N>CK,蚕豆平均产量NPK>OM+NPK>OM+NP>OM+NK>OM+N>CK;不同施肥结构肥料对水稻产量的贡献率OM+NP>OM+NPK>NPK>OM+NK>OM+N依次为32.1%30.2%27.8%27.6%27%,不同施肥结构肥料对蚕豆产量的贡献率NPK>OM+NPK>OM+NP>OM+NK>OM+N依次为18.4%16.3%14.3%13.6%13.3%。在水稻上以农家肥与氮磷化肥配施和农家肥与氮磷钾肥配施2种施肥结构对水稻产量的贡献率较大,但两者之间差异不大;次之的依次是氮磷钾肥配施,农家肥与氮钾肥配施和农家肥氮肥配施3种施肥结构肥料,但这3种施肥结构间肥料贡献率差异不大。在蚕豆上肥料贡献率较好的3种施肥结构依次为氮磷钾化肥配施,农家肥与氮磷钾肥配施和农家肥与氮磷化肥配施。
through long-term experiment research different fertilizer structure in clay soils field,the effect on crops yield were suitable for local agricultural production of fertilization structure.In yunnan province TongHaiXian Gong village.porcelain implementation 11 years of positioning fertilization field plot experiment,Research(1) no fertilizer(CK),(2) NPK fertilizers matchs shi(NPK),(3) livestock nitrogen with shi(OM + N),(4) nitrogen and phosphorus fertilizer with livestock joash(OM +NP),(5) OM + N and k fertilizer with livestock ishi(OM + NK),(6)livestock NPK fertilizers matchs shi(OM + NPK) six species of fertilization structure of rice,horsebean high and steady,fertilizer contribution and lasting impact.The result shows: the rice yield average OM + NP OM + NPK NPK OM + NK OM + N CK;average yields horsebean NPK OM +NPK OM + NP OM + NK OM + N CK;Different fertilizer structure fertilizer on the rice yield contribution of OM + NP OM + NPK NPK OM + NK OM + N CK,order 32.1%、 30.2%、27.8% 27.6% 、27%;different fertilizer structure of horsebean yield contribution of fertilizer NPK OM +NPK OM +NP OM + NK OM + N,percent higher order 18.4% 、16.3% 、14.3 、13.6%、13.3%.On rice with nitrogen and phosphorus fertilizer with livestock with shi and livestock with NPK fertilizers matchs shi two fertilization structure on the rice yield contribution of larger,but the distinction between a little;Commerical followed by NPK fertilizers matchs with nitrogen potash fertilizer,livestock with shi and livestock with nitrogen fertilizer fertilization structure was three,but this three kinds of fertilization structure between fertilizer contribution significant difference.In beans on fertilizer contribution better three fertilization structure in turn are respectively,with NPK fertilizers fertilizer,livestock and joash and livestock NPK fertilizers matchs with nitrogen and phosphorus fertilizer with shi,Two other kinds of application structure fertilizer contribution inferior and significant difference between them.Livestock and different kinds of chemical fertilizer match was with pure with NPK fertilizers are conducive to the rice was high and steady,but only from fertilization only to satisfy make beans and stable,and unable to meet after horsebean high yield.
