摘　　要：为了探明生防木霉菌剂LTR-2对冬小麦籽粒的影响,同时提供一种提高小麦品质的实践方法,以济麦44为试验材料,在孕穗期喷施不同浓度木霉菌剂LTR-2,对小麦籽粒千粒重、蛋白质、氨基酸和湿面筋含量进行测定与分析。结果表明,在小麦孕穗期喷施不同浓度的木霉菌剂,小麦籽粒千粒重、蛋白质、氨基酸和湿面筋含量均较对照有提高,孕穗期喷施木霉菌剂有助于提高产量以及小麦籽粒营养品质和加工品质。To explore the effect of Trichoderma harzianum LTR-2 on wheat grain quality and provide a practical method for improving wheat quality,parameters such as thousand seed weight as well as amino acid,protein,and wet gluten contents of winter wheat grains(cultivar Jimai 44)were analyzed after spraying different concentrations of T.harzianum LTR-2 suspension at the booting stage.The results demonstrate that the analyzed parameters had improved compared with the controls at the booting stage.The aforementioned results indicated that spraying of T.harzianum LTR-2 at the booting stage could improve the yield of wheat as well as nutritional and processing quality of wheat grain.
