吐鲁番是我国葡萄的主要生产基地,吐鲁番葡萄总产量占全疆的52.84%,是全中国的1/5。气温高、日照时间长、昼夜温差大,特别适合葡萄的生长,因而瓜果丰茂。这里种植的葡萄含糖量可高达22%~24%,因此被人们称为“世界葡萄植物园”。但是对于吐鲁番极端高温天气,现有的天气预报水平无法准确预报,无核葡萄品种在花芽分化阶段如果温度超过40℃,受高温影响而形成的花芽使来年葡萄的产量和质量有所下降。笔者本文主要对吐鲁番极端高温对无核白,无核白鸡心,无核紫,1124等4个无核葡萄品种花芽分化影响进行分析探讨并作试验观察。
Turpan is the main production base of grapes in China. The total output of Turpan grapes accounts for 52.84% of the total in Xinjiang, which is 1/5 of the total in China. High temperature, long sunshine, large temperature difference between day and night, especially for the growth of grapes, fruits and lush. The sugar content of grapes planted here can be as high as 22% to 24%, so they are called “World Botanic Gardens ”. However, for the extremely hot weather in Turpan, the existing weather forecasting level can not be accurately predicted. The flower buds of non-nuclear grape varieties under the influence of high temperature during the flower bud differentiation stage will lower the yield and quality of the grapes in the coming year if the temperature exceeds 40 ℃. In this paper, the author mainly analyzes and studies the effects of extreme temperature of Turpan on the differentiation of flower buds of four seedless grapes such as seedless white, seedless white chicken heart, seedless purple, 1124 and so on.
