肥料运筹和覆膜对小麦营养特征及产量品质的影响

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P2O5 135 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.

Effect of Fertilizer Application and Film-covered on the Yield and Quality and Nutritional Characters of Wheat

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 Eilm-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.
