根据实测资料统计分析表明,吐鲁番盆地4种主栽品种葡萄果粒重、浆果含糖量、成熟系数(糖酸比)与开花后≥15℃积温呈极显著的logistic生长曲线,而含酸量与开花后≥15℃积温呈极显著的指数关系,并据此确定了上述各生长因子或品质因子变化的关键时期。为采取科学的栽培管理技术措施或开展不同用途的葡萄适宜采摘期预测预报工作提供了科学依据。
According to the statistical analysis of the measured data, the grape grain weight, berry sugar content, maturity coefficient (sugar acid ratio) of the four main cultivars in Turpan Basin showed a significant logistic growth curve with the accumulated temperature of ≥15 ℃ after flowering, while the acid content And the blooming ≥15 ℃ accumulated temperature after a very significant exponential relationship, and thus determine the growth of these factors or quality factors of the key period. It provides a scientific basis for taking scientific cultivation and management technical measures or carrying out different types of grapes suitable for forecasting and forecasting of grapes.
