繁育葡萄“三当”苗,过去一直沿用嫩枝劈接法。但这种方法操作麻烦,嫁接时间短,当年难以育成健壮大苗。为了探索一种更有效的嫁接方法,从1998年开始,我们在安邱黄旗堡,寿光北洛、田马搞了葡萄贴接育苗对比试验。试验砧木用巨峰育砧,接穗用红提、黑提品种,共嫁接6320株,成活5814株,成活率92％,成苗5372株,成苗率达85％,分别比劈接法提高8％和19％,且生长健壮,木质化程度高。 1.材料和方法 采用红提、黑提当年新梢做接穗。接 Breeding grapes, “three when” seedlings, in the past has been followed by twigs split law. However, this method of operation is cumbersome, grafting time is short, then difficult to bred robust seedlings. In order to explore a more effective grafting method, starting from 1998, we engaged in the grape-grafted seedling contrast test in Anqiu Huangqi Fort, Shouguang North Luo, Tian Ma. The rootstocks were screened with giant bovine anvil, scion with red extract and black cultivars. A total of 6320 plants were grafted, 5814 survived, the survival rate was 92%, the number of seedlings was 5372, the seedling rate was 85%, which was 8% And 19%, and robust growth, high degree of lignification. 1 materials and methods using red, black tip that year to do new scion scion.
