喀什啥尔,又名新疆白葡萄,是我区古老的乡土树种。它具有穗粒大、适应性强、极丰产等优点。但其美中不足的是含糖量较低(13—16度),味偏酸而淡。为解决这一问题,我们于1984年利用二膦甘酸在果实生长期进行叶面喷洒,取得较为理想的效果。供试树为13年生,株行距6×1.5米,小棚架式,长梢修剪,树势中庸偏上。二膦甘酸由张家口化工研究所提供。试验以单蔓为小区,随机排列,二次重复。7月18日用温水将二膦甘酸溶解,配制成0.3％、0.5％、0.7％、1.5％、2.5％、3.5％六个不同浓度

Kashgar, aka Xinjiang white grape, is an ancient native tree species in our district. It has a large spike, adaptability, very yield and so on. But the fly in the ointment is the low sugar content (13-16 degrees), the taste of acid and light. In order to solve this problem, we made use of diphosphonic acid to spray the foliage in the fruit growing period in 1984, and achieved the ideal result. For the test tree 13 years old, spacing of 6 × 1.5 meters, small scaffolding, long shoot pruning, tree tendencies mediocre. Diphosphonic acid from Zhangjiakou Chemical Institute. Test to single vine for the district, randomly arranged, the second repeat. On July 18, diphosphonic acid was dissolved in warm water to prepare six different concentrations of 0.3%, 0.5%, 0.7%, 1.5%, 2.5% and 3.5%
