一九八五年以来,我们试验用全光喷雾沙床带叶扦插育苗获得成功。西峡县高中用此法培育难以生根的猕猴桃、苹果等树种,生根率达70%以上,生根时间33—35天,而且苗木长势良好。优点是:(1)省工省料易于掌握。全光喷雾扦插不需搭阴棚,减少了三揭四盖的工序。(2)生根快,成活率高。(3)扩大了插穗来源。除当年生半木质化的带叶绿嫩枝外,2—3年生的带叶分枝 Since 1985, we experimented with all-optical spray sand bed cuttings with leaf cutting success. Xixia County high school use this method to cultivate hard to root kiwifruit, apples and other tree species, rooting rate of 70% or more, rooting time of 33-35 days, and seedlings grow well. Advantages are: (1) labor saving and easy to grasp. All-optical spray cutting need to take shelter, reducing the process of three exposures and four covered. (2) Rooting fast, high survival rate. (3) to expand the source of cuttings. In addition to the year half-lignified green leaves, 2-3 years old with leafy branches
