摘　　要：以优质小麦贵农18号为材料,设计不同的施肥处理,研究分析了肥料对覆膜小麦生理特性及产量品质的影响。结果表明:肥料对覆膜小麦植株氮、磷、钾素和籽粒产量、品质有着重要的影响,在中等施肥条件下,随着肥料用量的增加,覆膜小麦植株氮、磷、钾素含量都随之增加,处理间产量差异显著;相同施肥用量前提下,前氮后移喷施能提高小麦的籽粒产量高达10.4%,植株氮、磷、钾素含量差异达到显著水平。在本试验条件下,磷钾肥施用量分别为P2O5135 kg.hm-2、K2O 135 kg.hm-2,氮肥施肥量为N 270 kg.hm-2,且于前期一次性施肥是实现覆膜小麦超高产的,有效措施。The Guinong No.18 was used as the material in this study,effects of fertilizer application on the yield and quality and nutritional cnaractes of film-covered wheat were analyzed.The results showed that the fertilizers had an important impact on the plant nitrogen,phosphorus,potassium content and grain quality of film-covered wheat,with the increasement of fertilizer application amount,the nitrogen,phosphorus,potassium content of film-covered whteat plant with all the increase in deal with a significant difference between the yield.Under the same amount of fertilizer,the permise of shift after spraying before the nitrogen can enhance 10.4% yield of wheat grain,the plant nitrigen,phosphorus and potassium content difference to achieve a significant level.Under the experimental conditions,the application amount for P and K are P2O5 135 kg/hm2,nitrigen fertilizer is N 270 kg/hm2,and in the one time application of early stage is an effective technical measure to achieve super-high-yield of film-covered wheat.
