250、500、1000ppm三种浓度的调节膦,均能抑制番茄植株的营养生长,浓度愈高,抑制作用愈强。经用三种浓度的调节膦处理后,番茄叶片的厚度、色泽、光合作用强度以及碳氮比都有所增加和提高,植株的营养生长和生殖生长得到较好的调节。处理后果实中的还原糖、转化酶活性和维生素C含量都有所增加,从而提高果实的品质。乙烯释放量的高峰提前,促进果实早熟,早期产量显著增加。两年来的试验结果表明,三种浓度的调节膦,都可以提高番茄果实的品质,产量也略有提高。
The concentrations of phosphine at three concentrations (250, 500 and 1000ppm) all inhibited the vegetative growth of tomato plants. The higher the concentration, the stronger the inhibitory effect. After treated with three concentrations of phosphine, the thickness, color, photosynthesis intensity and C / N ratio of tomato leaves increased and increased, and the vegetative growth and reproductive growth of plants were well regulated. After treatment, the content of reducing sugar, invertase and vitamin C increased, which improved the quality of fruits. The peak ethylene release ahead of schedule to promote premature fruit, early yield increased significantly. Two years of experimental results show that three concentrations of phosphine, can improve the quality of tomato fruit, the yield also increased slightly.
