为探寻适于重庆冬季柑桔育苗的嫁接方法,以软枝香橙为砧木品种,以爱媛38号(杂柑)、纽荷尔脐橙、塔罗科血橙和沃柑(杂柑)为接穗品种,比较研究了秋季单芽腹接法(传统方法)和冬季靠背露芽切接法嫁接育苗之间的成活率、用工量、育苗成本等。结果表明,柑桔采用靠背露芽切接法嫁接育苗的成活率达到94%以上,比传统方法提高6.4个百分点;每万株用工量只需6个工日,比传统法少近15个工日,每株节约成本约0.10元;苗木合格率(接口愈合良好)达99%以上,平均比腹接法高37.8个百分点。
In order to explore the grafting method suitable for winter citrus nursery in Chongqing, the soft-branch orange was used as the rootstock, and Ehime 38 (Citrus hybrids), Newhall navel orange, Taro blood orange and mandarin orange Scion varieties, Comparative study of autumn single-bud abdominal method (traditional method) and the winter back bud sprouting grafting seedling survival rate, labor, nursery costs and so on. The results showed that the survival rate of grafted seedlings of citrus with back-to-back bud-splicing method was above 94%, which was 6.4% higher than that of the traditional method. Only 6 workers were needed per 10,000 workers, 15 workers less than the traditional method Day, cost per plant about 0.10 yuan; seedlings pass rate (interface healing well) up to 99%, an average of 37.8 percentage points higher than the abdominal approach.
