摘要： Top-dressing can effectively improve crop yield, reduce extensive use fertilizer and decrease environmental pollution. At present, there are many methods of top-dressing for the winter wheat. However, only a few studies are available. Four top-dressing methods were set to study the effects of top-dressing methods on plant height growth, growth vigour and yield of winter wheat of "Shixin 828". The results showed that the growth and yield of wheat increased with the increase of top-dressing doses. Under the same top-dressing doses, the effect of deep application of prick-hole top-dressing (S1) on the growth and yield of winter wheat was the most significant, and there was no significant difference between other treatments. The highest yield was estimated to be 9.21 t/hm(2) under the treatment of N4 and S1. Compared with other top-dressing methods (S2, S3 and S4), the estimated yield of 8.82 t/hm(2) under the treatment of N3 and S1 was the second highest yield and was better than the other top-dressing methods. It may help in reducing top-dressing doses and increasing grain production. Therefore, S1 top-dressing method was found to be the most suitable method for winter wheat of "Shixin 828".
