巨峰葡萄适于我国南北各省栽培。江苏省８０年代开始大量发展，但均以种植扦插苗为主。在肥水条件良好的田块扦插苗生长旺盛，树势较强，而在丘陵地区则生长慢、结果迟、树势弱。如选择耐干旱的适宜砧木，利用嫁接苗栽培，则可解决上述问题。为此，我们进行了砧木筛选试验。１ Kyoho grapes suitable for cultivation of our provinces in northern and southern provinces. In the 80’s of Jiangsu Province, a large number of development began, but the main planting cutting seedlings. In the field of fertile water and good plots of cutting seedlings vigorous growth, strong tree vigor, while in hilly areas grow slowly, the result is late, the tree weak potential. Such as the selection of suitable drought-resistant rootstocks, the use of grafted seedlings cultivation, you can solve the above problems. To this end, we conducted a rootstock screening test. 1
