山地白枇杷高接换种试验

Top grafting experiment of Eriobotrya japonica in mountainous region

在白枇杷高接换种中,采用不同嫁接时间、不同发育程度接穗以及接后不同护理方法等3种处理多种水平试验,证明不同处理和水平对嫁接成活率和新梢生长量都有显著影响。采用半木质化穗条,穗直径为0 81～1 30cm,3月上旬嫁接,嫁接处用套袋+袋下方留出小孔+稻草遮荫等综合技术成活率最高,达86 67%,新梢生长量最大,达39 73cm。

In the high grafting of Eriobotrya japonica,three experiments are conducted in the conditions of different grafting time,different scion development degrees and different treatment after the grafting.The results show that different treatments and different conditions have significant effects on the grafting survival rate and length of new treetops.The survival rate is the highest when the diameter of semilignified scion is about 081～130 cm and grafted in early March,and grafting points are covered with bags and shaded with straw.The highest survival rate is 8667%.In these conditions,the longest new treetop is 3973 cm.[Ch,4 tab.9 ref.]
