摘　　要：通过大田小区试验研究5种不同施肥方式对小麦产量及其构成因素的影响,以此来确定小麦最佳施肥位置及氮肥种类。试验结果表明,控释肥一次性撒施旋耕处理的小麦产量与尿素一半撒施旋耕、一半追肥处理的产量接近,且均较高。控释肥条施于种子正下方或侧下方的处理小麦产量显著低于控释肥一次性撒施旋耕的处理,但均优于传统尿素全部撒施后旋耕播种的施肥方法。因此,在生产中可以推广采用控释肥一次性撒施旋耕的方法施用氮肥,既可以提高小麦产量还能够减少劳动量。Five different fertilization ways were tested to determine the best fertilizer placement and nitrogen species for wheat through plot trial in field. The results showed that the wheat yield of controlled release fertilizer applied one-time with rotary tillage treatment was higher and close to that of urea applied half with rotary tillage and half dressed. When the controlled release fertilizer was applied underface or below the side of seeds,the wheat yield was significantly lower compared to the treatment of one-time application of controlled release fertilizer with rotary tillage,and both them were superior to the treatment of broadcasting all traditional urea with rotary tillage. Therefore,the one-time broadcasting of controlled release fertilizer with rotary tillage could be applied in production,which could not only improve the wheat yield but also reduce the labor.
