| 摘 要： | 目的]明确在水稻秸秆全量还田的条件下,不同时期施肥在提高小麦产量中的贡献大小。方法]共设7个试验处理,研究在稻秆全量还田的条件下不同时期施肥和不同运筹施肥比例对小麦的茎孽动态和产量结构的影响。结果]各处理的小麦基本苗差别不大,返青苗、高峰苗和有效穗数均明显高于对照;各处理的小麦株高、穗长和穗数均高于对照;与对照相比,各处理的增产率为76.8%~146.5%。结论]总氮量为300 kg/hm~2,基肥占60%,不施分蘖肥或少施分蘖肥,穗肥占40%为最优施肥方案。

Effects of Fertilizer Dosage on the Yield and Tiller Dynamics of Wheat under Returning Straw to the Field Wholly |
| |
| Abstract: | Objective]To find the contribution in enhancing the wheat yield in different fertilization periods under the condition of returning rice straw to the field.Method] There were in all seven test treatments.We researched the effects of fertilization period and ratio on the tiller dynam-ics and yield structure of wheat under the condition of returning rice straw to the field wholly. Result] There were no great differences in wheat basic seedlings between treatments.Reviving seedlings, peak seedlings and effective spikes in treatment groups were all significantly higher than those of control.Plant height and ear length and ear number of wheat in treatment groups were all higher than those in control group.Compared with control group, the yield increasing rate of each treatment was between 76.8% and 146.5%.Conclusion] The total nitrogen amount is 300 kg/hm2 , base fertilizer accounts for 60%, no or less tillering fertilizer should be adopted.40% ear fertilizer is the optimal fertilization scheme. |
