| 摘 要： | 在小麦药隔分化期 (4月 2 6日 )、灌浆期 (5月 30日 )各喷施一次混配肥或两期都喷施 ,均能提高小麦产量 ,以灌浆期喷一次经济实惠。喷施混配肥可增强光合作用 ,防止叶片早衰 ,使茎秆坚韧 ,防止后期倒伏 ,对成穗率、千粒重有明显促进作用 ,试验增产 10 .6 1%～ 12 .4 4 %。

| Abstract: | Spraying mixed fertilizer at the stage of anther differentiation (April 26), or milk tillering (May 30), or at both stages could increase wheat yield. Spraying once at milk tillering stage had best economical benefits. Spraying mixed fertilizer could enhance wheat photosynthesis, prevent early aging, strengthen the xylem and natural fiber of stem, prevent lodgment in late period, increase bear ear rate and the weight of 1 000 kernels. All this led to high wheat yield, and the increment rate was 10 61%～12 44%. |
