新疆区域控释肥对玉米农艺性状及产量的影响

Effects of Controlled-Releasing Fertilizer on Agronomic Characters and Yield of Maize in Xinjiang Area

本文以玉米品种新玉29为材料,研究3个不同施肥处理对玉米生长及产量的影响。结果表明,与习惯施肥相比,普通控释肥与巨能省控释肥均能够提高玉米株高、增加茎粗,且各处理间差异达显著水平;普通控释肥与巨能省控释肥均可以显著提高玉米果穗的穗长,增加行粒数、穗粒数及百粒重,最终提高产量;巨能省控释肥较普通控释肥在减少肥料投入的情况下亦能改善玉米农艺性状与产量。由此说明,控释肥在新疆玉米种植区域应用能够达到减肥、提质、增产的效果,本试验中巨能省控释肥效果更佳。

In this study,using new maize variety Xinyu 29 as material,the effects of three different fertilization treatments on maize growth and yield were studied.The results showed that compared with conventional fertilizers,both conventional controlled-releasing fertilizers and extremely-saving controlled-releasing fertilizers could increase plant height and stem diameter,and the difference among treatments was significant.Both conventional controlled-releasing fertilizers and extremely-saving controlled-releasing fertilizers could significantly increase ear length,grain rows,ear grain number and 100-grain weight of maize,and ultimately increased the yield.Compared with the conventional controlled-releasing fertilizers,the extremely-saving controlled-releasing fertilizers could improve the agronomic traits and yield of maize under the condition of reducing fertilizer input.In conclusion,the application of controlled-releasing fertilizers in Xinjiang maize growing area can achieve the effects of reducing fertilizer amount,improving quality and increasing yield,and the effect of extremely-saving controlled-releasing fertilizer is better.
