摘　　要：试验结果表明,促丰宝 液肥对小麦生长发育、产量构成因素及产量均有显著的促进作用。平均株高和茎粗比对照增加5.71cm和0.598mm,穗长和小穗数增加0.83cm和1.56个,穗粒数和千粒重增加8.36粒和3.286g,产量提高23.57%。促丰宝 液肥对小麦各测定项目的影响:株高、穗长、小穗数和穗粒数X2>X1效应,千粒重X1=X2,茎粗和籽粒产量X1>X2效应。各项目达最佳效果和小麦产量≥5200kg/hm2的促丰宝 液肥用量为:拌种6.91～16.44mL/kg,叶面喷施浓度为2.99～5.42mL/kg。The experimental results showed that Cu Feng Bao(CFB) Ⅱ fertilizer had obvious effects on the growth development and yield component factors of wheat.After CFB was applied,the height,stem diameter,ear length,the number of ear and grains per ear,TGW and yield of wheat increased by 5.71 cm,0.598 mm,0.83 cm,1.56,8.36,3.286 g,23.57% respectively in comparison with control.When dosage of CFB at 6.91 mL to 16.44 mL/kg was used to dress seeds or at 2.99 mL to (5.42) mL/kg to spray on the wheat plant,the harvested yield of wheat attained 5 200 kg/hm^2.
