采用芽苗砧嫁接银杏比芽接法缩短育苗期2—3年,比劈接缩短育苗期3—4年。一般成活率均在90%以上,且苗木优质,成本低。一、培养芽苗砧银杏种子采收后,精选出受粉良好、发育正常、充分成熟、粒大、饱满、无病虫害的种子,按常规方法进行贮藏。翌年三月放入温室或塑料棚内,温度保持15—25℃,混湿砂催芽。种子露白后,按5厘米的间距侧放于砂床沟内,覆砂4厘米。这样胚根向下生长,胚轴向上生长,不弯曲,易嫁接;成活率高。幼芽出 The use of bud grafting grafting ginkgo bud method to shorten the nursery 2-3 years, shorter than the short cut nurturing 3-4 years. The general survival rate is above 90%, and seedlings of high quality, low cost. First, cultivate sprout seedling ginkgo seeds harvested, selected by the powder good, normal development, fully mature, large grain, full, no pests and diseases of the seeds, according to the conventional method of storage. March next year into the greenhouse or plastic shed, the temperature maintained at 15-25 ℃, mixed wet sand sprout. After the seeds are exposed to the white, they are placed on the sand bed and ditch at a distance of 5 cm and covered with 4 cm of sand. This radical roots down growth, embryo axis upward growth, no bending, easy grafting; high survival rate. Young buds out
