摘要
采用化肥、栏肥和秸秆还田及其不同组合的施肥处理,以长期不施肥料为对照,对麦-稻两熟作物进行了田间试验,以确定不同施肥处理对麦稻产量和品质的影响。结果表明:在施等量化肥3个处理中,以栏肥配施化肥麦稻有效穗最高,产量也最高,其次为秸秆还田配化肥处理,单施化肥处理的麦稻有效穗最低;在不施化肥3个处理中,施栏肥麦稻有效穗及其产量高于秸秆还田处理和对照。施有机肥或秸秆还田,促进了作物生长,提高了秸秆重量,也增加了秸秆中全氮、全磷和全钾含量。
A long-term nonfertilized plot was used as a control plot and field experiments of ricewheat cropping were conducted through different combined applications of chemical fertilizer, barnyard manure and straw to study the effects of different fertilizer treatments on the yield and quality of rice-wheat cropping. The results showed that in the 3 fertilizer treatments with the same chemical fertilizer rate, the combined application with barnyard manure was the highest in productive ears and yields of rice and wheat, the combined application with straw ranked second, and the application of chemical fertilizer alone was the lowest. In the 3 fertilizer treatments without chemical fertilizer,applying barnyard manure gained more productive ears and higher seed yields of rice and wheat than returning straw to field and CK, Applying manure or returning straw to field promoted the growth of crops,increased the weight of crop straws and improved the N,P and K contents of crop straws.
