本文主要探索不同配方的多功能种肥素对小麦苗期及产量的影响，从而筛选出有利于小麦壮苗、提高冬小麦产量的配方。试验结果表明，冬小麦多功能种肥素可促进根系的发育，促进茎基部粗壮，增加苗期生物量，增加分蘖成穗率，具有显著的增产效果。其中改良９ 号配方效果最好，较对照增产２３ ％ ，较台湾杨馥成在大陆生产的活力素增加９－２

Through studying the effect of all kinds of multifunctional seeding fertilizers on the seeding and yield of winter wheat,the prescription helpful for forming strong wheat seedling and raising grain yield was screened .The result indicates that the selected multifunctional seeding fertilizers can improve the development of root system and form a thick and strong stem base,increase the biological weight in the seedling stage,raise the rate of tiller forming ear and have the markes effect on increasing yield.The prescription“Improved Number 9” had the best effect among all the treatments,with the yield more 23% than “CK” and 9 2% than “Vigor elements”.
