【摘要】 本文报导了在葡萄(品种:金后)盛花期与果实膨大期叶面喷施多效增糖灵,可使葡萄叶片功能和浆果中转化酶活性提高.成熟浆果的糖度比对照提高2度左右,维生素C的含量有所增加,酸度有所降低.叶面喷施多效增糖灵,果穗紧密整齐,小粒减少,百粒重增加,浆果产量可提高20%左右.喷药植株的新梢增粗,树势旺盛.更多还原

【Abstract】 Leaf treatment of grape twice in its full—blooming period and 4—weeks thereaf-ter with FIG (mixture of fulvlc acid and trace elements) could increase the surgar content of berries.The physiological mechanism of this process was studied.The chlorophyll content, the intensity of photosynthesis were increased in treated plants: while the activity of invertase ot treated plants were also increased, thus accerelated the accumulation of monosaccharides in the berries.Sugariness was increased from 10.6% in control to 13.2%; the total acidity decreased vitamin C increased and the quality of berries improved.By spraying FIG resulted in the increment of the berry yield by 20% in our expeiment.更多还原
