小粒咖啡鲁伊鲁—11嫁接改良及繁育试验研究

用咖啡F1优良复合杂交种鲁伊鲁－11作接穗，开展咖啡幼苗嫁接繁育和大树换冠改造试验。幼苗春季嫁接，当年可出圃种植；大树换冠改造投产早，经济效益显著。通过嫁接部位套塑料袋保暖保湿措施使适宜的嫁接期延长。采用切接法并利用环保型绑缚材料接蜡膜，既简便，包扎严实，又节省接穗材料，成活率很高，促进了小粒咖啡杂交F1品种的推广应用。

Improvement and Propagation of Arabica Coffee Ruiru-11 by Grafting

With the scion of excellent composite hybrids Ruiru-11, the test was carried out about coffee seedlings grafted breeding and crown transformation of big tree. Seedlings grafted in spring can be planted on the year. The earlier of the crown transformation and the more significant of the economic benefits. Suitable grafting period was expanded by graft part setting plastics to keep warm and wet. The survival rate was very high and the application and the popularization of F1 hybrid varieties of Arabica coffee were promoted by using incision grafting technique and the wax film, which is simple, tightly bandaged, but also saves scion material.
