桃树矮化砧木樱桃李嫁接3个桃品种的表现

Study of dwarfing rootstocks of peach on myrobalan plum

以樱桃李、青州蜜为砧木,分别嫁接3个桃品种:春艳、春元、北京52,经10年的栽培观察发现:与青州蜜砧穗组合相比,樱桃李砧穗组合树体矮化,冠径小,长势弱,总枝量少但中短枝/长枝比率高;品种与砧木的粗度比小,即亲和性相对差;果实较小但产量高;果实的可溶性固形物含量高,品质优;樱桃李砧穗组合具有矮化的特性。

Using myrobalan plum and Qingzhoumi as rootstocks,and grafting Chunyuan,Chun⁃yan,and Beijing No.52 peach varieties,after 10 years of cultivation observation,it was found that compared to Qingzhoumi rootstock combinations,the myrobalan plum rootstock combinations resulted in dwarf trees with weaker growth,shorter tree height,smaller crown diameter,fewer total bran⁃ches,and a higher ratio of medium-short branches to long branches.The thickness ratio between the varieties and rootstocks was smaller,indicating lower compatibility.The fruit of the myrobalan plum rootstock combinations was smaller,but the yield was significantly higher,and the soluble sol⁃ids content of the fruits was significantly increased,resulting in higher quality.Therefore,myroba⁃lan plum rootstock combinations are more suitable for facility dwarf.
