提高嫁接成活率,不但可加快成苗速度,而且可节约生产投资。三十烷醇、“九二○”和“2,4-D三种激素都具有提高嫁接成活率的作用。经过两年试验,笔者认为:在春、夏季嫁接都可采用激素溶液浸芽,使用浓度以;三十烷醇0.5—1ppm、“九二○”50—100ppm、2,4—D10ppm为宜。欲接前,先配好溶液,然后将接芽削入溶液内,浸泡1小时后即可嫁接,接芽浸泡时间可持续5小时。在春季,接后1月左右,夏季,接后15天左右即可解除薄膜,检查成活。一般来讲,在同等条件下,浸芽与不浸相比,成活率可提高4—10％。三种激素处理中,以三十烷醇和“九二○”效果好。三十烷醇和2,4—D均属于生长刺激素,
Raising the survival rate of grafting will not only accelerate the speed of seedling but also save production investment. Triacontanol, “nine two ○” and “2,4-D three hormones have the role of improving the survival rate of grafting.After two years of testing, I believe that: in spring and summer grafting hormone solution can be used soaked buds, Use the concentration of; triacontanol 0.5-1ppm, ”9020“ 50-100ppm, 2,4-D10ppm is appropriate. To take before the first with a good solution, then pick bud into the solution, soak for 1 hour After the grafting can be, pick bud soak for 5 hours in the spring, pick then about January, summer, then about 15 days to release the film, check the survival.In general, under the same conditions, soaking Bud and Compared with no immersion, the survival rate can be increased by 4-10% .Three hormones in the treatment of triacontanol and ”nine two ○" effect.And triacontanol and 2,4-D are growth stimulating hormone,
