摘　　要：在适宜氮素的基础上，采用增加磷、钾肥的投入，同时减少传统分蘖肥和返青肥的施用比例，增加基肥和后期拔节孕穗肥使用量的肥料运筹试验手段，达到了促进分蘖，延长花后叶片光合功能期，提高群体成穗率，增加每穗粒数和粒重，从而达到提高产量的作用。The experiments with N application at different wheat growth stages and Differentapplication rates ofPand K were carried out in ShanghaiBaoshan and Minhang Districts from 1998 to 1999.The results show :on the basis of applying enough N and increasing theratios ofP,K,thefertilizerm anagem entofdecreasing theN dosesattillering and reviving stages butincreasing the basaldressing as wellas the top dressing at booting stagein contrastto thetraditionalmethod can increasetillernum berand earingrate,prolong photosynthetictim eofleavesafteranthesisand increase theearnumberofpopulation,grain num berand w eightperearand so prom ote high yield.
