摘要： 为筛选适合江苏小麦生产和提高肥料利用率的肥料产品，应用心连心控失尿素、含锌尿素、含锰尿素，通过大田试验，研究心连心控失尿素和含锌锰尿素对江苏地区小麦主栽品种的产量影响。结果表明：心连心控失尿素和含锰尿素适合江苏小麦区的肥料施用，与普通尿素相比分别增产7.32%、4.27%，氮肥利用率分别能达到32.85%、23.75%，而心连心含锌尿素和普通尿素＋锌处理对小麦的增产效果不佳，说明在含锌较高的土壤上种植小麦不适合施用含锌肥料，这为小麦增产和推广提供理论依据。

Abstract: To screen the fertilizers suitable for Jiangsu wheat growth and increase fertilizer utilization rate, we used Xinlianxin controlled release urea, zinc urea and manganese urea to study their effects on wheat yield. The results showed that Xinlianxin controlled release urea and Mn urea were appropriate for wheat production in Jiangsu, the wheat yield increased by 7.32% and 4.27% compared with common urea, nitrogen utilizationrate reached 32.85% and 23.75%, respectively. However, the effects of Xinlianxin zinc urea and common urea with zinc treatment on wheat yield were poor. It was not suitable to apply zinc fertilizer to the soil with high zinc content. The results provide a theoretical basis for wheat production and promotion.
