摘　　要： 在小麦生育后期喷施２００ｍｇ／ｋｇ浓度的ＧＹＢ根叶宝，能明显地改善叶片的净光合速率、叶绿素含量和叶片代谢活力，叶片的光合速率高值持续期、叶绿素含量缓降期延长３ｄ；同时使根系生理活性增强．从而使籽粒千粒重、每穗粒数增加，增产１１．４％～１９．８％． The leaf photosynthetic rate,chlorophyll content and metabolic activity of wheat were significantly after improved sprayed with 200 mg/kg GYB Genyebao,a yield increasing agent,during the later growth stage.The photosynthetic active duration (PAD) and chlorophyll steady phase (RSP) lasted 3 d more.In the same time,the roots physiological activity was promoted as well.So as that,the grain weight and kernel number per spike increased and the yield increased bby 11 4%￣19.8% over the control.
