5年连续施用氯化铵结果证明:柑桔较耐氯.叶片含氯5000ppm,无异常表现,成年树较幼年树耐氯,柑桔吸收氯很快,叶器官含量高,老叶大于嫩叶,抽新梢后老叶中氯向嫩叶转移,但果汁中含Cl~-很少。Cl~-对柑桔外观品质无明显影响,有延迟着色趋向,对固形物、柠檬酸含量有降低趋势,对维生素C无明显影响,与尿素比,产量亦无明显差异。
5 years of continuous application of ammonium chloride results show that: citrus is more resistant to chlorine leaves chlorophyll 5000ppm, no abnormalities, adult trees than young trees resistant to chlorine, citrus absorption of chlorine quickly, leaf organ content is high, older leaves than young leaves , After pumping the shoots old leaves of chlorine to the leaves of the transfer, but the fruit juice containing Cl ~ - rarely. Cl ~ - had no significant effect on the appearance quality of citrus fruits, but had a tendency of delayed coloring. The contents of citric acid and citric acid decreased, but had no obvious effect on vitamin C and no significant difference with urea ratio and yield.
