Abstract:
According to the actual data showed that grape′s weight,content of sugar mature coefficient (the rate of sugar and acid)have assumed extreme remarkable Logistic growing bend line with ≥15℃ accumulated tempreture of after blossom for four kinds of main plant breeds in Tulufan Basin,but extreme remarkable exponential function for content of acid with ≥15℃ accumulated tempreture of after blossom,so that the crucial period of different growing element or quality element were defined which provides scientific basis for scientific management measure or develop different uses of grape-picking period.
