| 对不同品种玉米在春覆膜及不同氮磷肥施用量条件下产量和籽粒主要品质变化的研究结果表明:氮肥和品种是影响玉米产量和籽粒品质的主要因素;在覆膜和露地栽培方式下,增施氮肥,玉米籽粒中蛋白质分别含量增加0.63%0.87%、0.71%0.75%,淀粉含量分别减少0.78%1.74%、0.54%1.02%;覆膜可增大不同品种玉米籽粒容重5.824.5g/L,增加籽粒淀粉含量0.32%2.69%,降低籽粒中蛋白质含量0.29%1.63%;施肥和覆膜对玉米籽粒脂肪和赖氨酸含量的影响较小。增施氮磷肥,能够明显提高玉米单产;春季覆膜栽培提高玉米单产777.002851.50kg/hm2。 |

| In this paper, different maize varieties were used to study the effects of nitrogen and phosphorus application on yield and quality indexes of maize with plastic film mulch. The main results were as follows: (1)Nitrogen and variety were the main factors that influenced the yield and seed quality; (2)The protein contents of maize were increased by 0.63%0.87% (plastic film mulch) and 0.71%0.75% (conventional cultivation), and the starch content were decreased by 0.78%1.74% (plastic film mulch) and 0.54%1.02% (conventional cultivation) when nitrogen fertilizer was added; (3)Seed bulk density and starch content were increased by 5.824.5 g/L and 0.32%2.69% respectively and proteint content was decreased by 0.29%1.63% by plastic film mulching; (4)Fertilizer application and film mulch had little influence on seed fat and lysine content; (5)Nitrogen or phosphorus fertilizer and plastic film mulch in spring could improve maize yield significantly. |
