冬季将葡萄枝剪成二芽一段,放湿沙中保藏,1987年2月21日,贮藏插条基部1～2cm用不同浓度硝酸稀土溶液浸泡处理。稀土溶液处理的浓度和时间为100、200、300、400、500ppm浸泡12小时;0.1、0.2、0.3、0.4、0.5％浸泡0.5小时;设清水处理为对照。每处理30根插条。处理后插条斜插于沙床上,盖塑料薄膜,保持沙床湿润。35天后,100ppm处理的生根率为30％;200、300ppm,0.1、0.2、0.3％处理的生根率为20％;0.4、0.5％和对照的生根率为10％。处理55天后,所有插条均生根。100ppm硝酸稀土处理的发根数最多,为12条,是对照的2倍;平均根长最长,为4.1cm,比对照增加37％。0.2、0.3％硝酸稀土处理的生根量亦较多,为11条,但平均根长仅为3.1cm。(邹玲等) 摘自《福建果树》1989年第1期
Winter grapes cut into two buds for a period, placed in wet sand preservation, February 21, 1987, storage of cuttings at the base of 1 ~ 2cm with different concentrations of rare earth nitrate solution soaked treatment. Rare earth solution concentration and time of 100,200,300,400,500ppm soak for 12 hours; 0.1,0.2,0.3,0.4,0.5% soaked 0.5 hours; set water treatment as a control. 30 cuttings per treatment. After the treatment of oblique cuttings inserted in the sand bed, cover the plastic film to keep the sand bed moist. After 35 days, the rooting rate of 100ppm treatment was 30%; the rooting rate of 200,300ppm, 0.1,0.2,0.3% treatment was 20%; the rooting rate of 0.4,0.5% and control was 10%. After 55 days of treatment, all cuttings were rooted. 100ppm nitric acid rare earth treatment of the largest number of hair roots, 12, is 2 times the control; the longest average root length, 4.1cm, 37% increase over the control. 0.2, 0.3% rare earth nitrate rooting is also more, for 11, but the average root length of only 3.1cm.
