不同浓度NaHSO3 在桃树上的应用研究表明 ,以 ρ(NaHSO3 ) =10 0mg/L使用效果最佳 .于果实膨大期喷施 3次 ,能明显提高桃树座果率和单果重 ,增加产量 ,改善果实品质 ,促进新梢生长 .实验证明 ,NaHSO3 的这些功能与其抑制过氧化氢酶活性 ,提高光合速率及希尔反应活力 ,增加叶绿素含量与比叶重 ,促进光合产物输出等多重生理效应相关 .表 4参 11 The application of different concentrations of NaHSO3 in peach trees showed that the best effect was obtained with ρ (NaHSO3) = 100 mg / L. Spraying three times during the fruit enlargement period could obviously increase the peach fruit rate and fruit weight and increase the yield , To improve fruit quality and promote shoot growth.Experiments show that these functions of NaHSO3 and its inhibition of catalase activity, increased photosynthetic rate and Hill reaction activity, increased chlorophyll content and specific leaf weight, and promote photosynthetic output and other multiple physiological effects Related Table 4 Senate 11
