The present invention relates to a cucurbit double grafting method, utilizing a hypocotyl or a stem of a definite bud or a leaf of a to-be-harvested cucurbit as a scion to be cooperatively grafted to lower hypocotyls of two excellently compatible cucurbits that are served as stocks. The grafting method sequentially comprises the following steps: a stock plantation step, providing two cucurbits served as proximal stocks for plantation a scion-acquiring step, acquiring the hypocotyl or the stem of the definite bud or the leaf of the to-be-harvested cucurbit as the scion a stock-connecting operation, correspondingly destroying the lower hypocotyls of the two stocks so that the lower hypocotyls of the stocks are correspondingly formed with individual granting sites a scion-cutting step, cutting the hypocotyl or the stem which is located below the definite bud or leaf of the scion into halves so that the hypocotyl or the stem is formed with two grafting parts with cutting surface respectively and a grafting step, respectively placing the two grafting parts at the grafting sites of the lower hypocotyls of the two stocks, enabling the grafting sites of the lower hypocotyls of the two stocks and the cutting surfaces of the grafting parts of the scions to be mutually approached and attached, and externally fastening the lower hypocotyls of the two stocks and the scions. Accordingly, a grafting process is completed.一種瓜類雙重嫁接方式,其係將一種欲獲得之瓜類取至少含有一定芽或一葉片的胚軸或莖作為接穗,配合嫁接於兩株以親和性佳之瓜類作為砧木之下胚軸處,而該嫁接方法係依序包含有下列步驟:砧木種植:將兩株瓜類作為砧木相近進行種植;取得接穗:將所欲獲得的瓜類,取其至少含有一定芽或一葉片的胚軸或莖作為接穗;砧木接作:將兩砧木下胚軸相對應進行破壞加工,使兩砧木下胚軸相對應皆形成有一嫁接處;接穗切削:將接穗定芽或葉片下方胚軸或莖切成兩半,使胚軸或莖分別形成具切面二嫁接部;進行嫁接:將接穗之二嫁接部分別放入兩砧木下胚軸之嫁接處,且將兩砧木下胚軸之嫁接處與接穗之嫁接部切面相互靠近貼合,再由外側將兩砧木下胚軸連同接穗予以進行固定,即可完成嫁接程序。(10)‧‧‧接穗(11)‧‧‧嫁接部(20)‧‧‧砧木(21)‧‧‧嫁接處
