摘　　要：　测定了肥力高对小麦植株性状及产量的影响,结果表明,施用肥力高对小麦植株性状、产量构成因素和产量有显著的促进作用。平均株高增加2.08cm,茎粗增加0.31mm,穗长增加0.27cm,小穗数增加0.97,穗粒数增加3.93,不孕小穗降低0.68,千粒重提高0.98g,平均增产22.34%。肥力高对小麦株高、茎粗、穗长、小穗数、穗粒数的影响为叶面喷施>拌种,对不孕小穗和千粒重的影响为拌种>叶面喷施。小麦植株性状达预定目标和产量≥4500kg/hm2的肥力高用量为拌种5.45～15.43kg/hm2,叶面喷施浓度9.48～20.78g/kg。The effect of FLG on plant character and yield of wheat were studied.The result indicated that FLG could promote wheat's growth and yield.After FLG was applied to wheat,average height,stem thickness,ear length,number of ear,number of grain per ear and TGW increased in turn by (2.08) cm,0.31 mm,0.27 cm,0.97 and 3.93 and 0.98 g,respectively sterile ear decreased by 0.68,average yield increased by 22.34%.What's more,when FLG was sprayed on the leaves,it has the great effect on height,stem thickness,ear length,number of ear and number of grain per ear,when adhering to seed the great effect on sterile and TWG.The total amount of applied FLG was 5.45 to 15.43 kg/hm^2 as adhering to seed,then wheat character was as good as expected and the yield was not less than 4 500 kg/hm^2.
