| 以长达20年的微量元素肥料定位实验数据为基础,分析长期施用微肥对冬小麦农艺性状及产量的影响。结果表明:长期施用微肥对冬小麦有明显的增产效果,小麦施B增产481.8 kg/hm2,增产率30.3%;施Zn增产610.8 kg/hm2,增产率38.4%;施Mn肥籽粒增产368 kg/hm2,增产率23.1%;施Cu籽粒产量无明显变化。施用微肥小麦,籽粒、秸秆中微量元素含量增加,籽粒中含锌量增加10.47 mg/kg,增加率为49.79%;秸秆中含锌量增加3.84 mg/kg,增加率为47.5%;与施KH2PO4肥相比,籽粒中含锌量增加8.03 mg/kg,增加率为33.0%;秸秆中含锌量增加4.78 mg/kg,增加率为66.8%。 |

| Based on along-ter mexperi ment of applying micronutrients for 20years effects of long-ter mapplying micronutrients fertilizer on wheat yield and the structure of wheat were investigated.The results showed that thelong-ter mapplication of micronutrients canincrease the wheat yield significantly.By applying Bfertilizer grain yield was increased by 481．8kg／hm2 with a increase rate of 30．3％；by applying Zn fertilizer grain yield was increased by 610．8kg／hm2 with aincrease rate of 38．4％；by applying Mn fertilizer grain yield was increased by 368kg／hm2 with aincrease rate of 23．1％；by applying Cu fertilizer grain yield was not changed significantly．By applying micronutrients the content of micronutrients in grain and stalk were also increased． The content of zinc in grain and stalk was increased by 10．76mg／kg and 3．84mg／kg compared to the control treat ment while the content of zincin grain and stalk was increased by 8．03mg／kg and 4．78mg／kg compared to the KH2PO4fertilizer treat ment. |
