摘　　要：研究了保护性耕作及施用控释肥对小麦生长和产量的影响。结果表明：同在保护性耕作条件下,施用较好的控释肥料能提高小麦产量9.3%-12.6%。在肥力水平较高的居巢区,免耕控释肥处理与平衡施肥翻耕处理小麦产量差异不明显。The effects of conservation tillage and application of controlled-release fertilizers on the growth and yield of wheat were studied. The results showed that the wheat yield could be increased by 9.3% - 12. 6% through appling better controlled-release fertilizers under the same condition of conservation tillage. There was not significant difference in the yield between the treatments of no-tillage with controlled-release fertilizers and plowing with balanced fertilization in Juchao District in which the fertility level was higher.
