甜樱桃矮化砧木吉塞桓5号、吉塞植6号由山东省果树所刘庆忠研究员自国外引进,于2004年获得了国家林业局林木品种审定委员会颁发的林木良种证书。该类砧木抗病、抗寒、抗旱、结果早,解决了甜樱桃乔化、结果晚、产量低、死树等难题,引领我国甜樱桃业进入矮化密植新时代。该项研究 Sweet cherry dwarf rootstock Guiseihuan 5, Guise planting 6 by the Shandong Province fruit tree researcher Liu Qingzhong introduced from abroad, in 2004 won the State Forestry Administration forest variety certification committee issued a certificate of tree seed. Such rootstocks have the problems of disease resistance, cold resistance, drought resistance and early fruiting, which solved the difficult problem of sweet cherry Qiaohua, the late result, low yield and dead tree, leading the sweet cherry industry of our country into a new era of dwarfing and dense planting.
