摘　　要：为了对纳米级材料胶结包膜型缓/控释肥料的缓/控释性能进行准确的评价,以3年6季作物定位施肥试验为基础,对冬小麦和夏玉米的产量及部分品质进行了监测。结果表明,与等量氮磷钾化肥配施相比,4种纳米级材料胶结包膜型缓/控释肥料不同程度地提高了小麦和玉米子粒产量和蛋白质产量,但蛋白质含量增加不显著,可溶性总糖含量反而降低。纳米级材料胶结包膜型缓/控释肥料对提高冬小麦的产量和品质有一定的促进作用,但不同肥料促进作用大小不同。In order to evaluate performance of slow/controlled release fertilizer coated and felted by nano-materials,yield and quality of winter wheat and summer corn were determined through the 3-year and 6 -season field experiment in winter wheatsummer corn rotation.The results showed that grain yield and protein were improved in some degree,but protein content was increased insignificantly,and soluble sugar content was decreased by slow/controlled release fertilizer coated and felted by nano-materials compared with NPK chemical fertilizer.It was effective to use slow/controlled release fertilizer coated and felted by nano-materials to improve wheat yield and quality but the effects were different.
