中国农业科学院郑州果树研究所的科技人员,试验成功一种加快繁殖葡萄营养苗的新方法。选择一片需要淘汰的成龄葡萄园作砧木区,4月份,葡萄萌芽前将砧木地上部离地3厘米处平茬,平茬后锯口处覆土保湿,平茬后15天左右就会产生大量萌蘖,萌蘖枝去弱留强。5月上旬至6月上旬,选用枝条中部半木质化的绿枝单芽作接穗进行劈接,接后用薄膜条缠严嫁接部位,只露出接芽。接后灌水促进伤口愈合。每株砧木接活2个接穗为宜,一次接不
Chinese Academy of Agricultural Sciences Zhengzhou Fruit Research Institute of scientific and technological personnel, a successful trial of a new method to accelerate the breeding of grape seedlings. Select a need to eliminate the aging vineyard for the rootstock area, in April, the grapes before the rootstock rootstock 3 cm off the ground stubble, stubble after the kerosene cover soil moisture, stubble after about 15 days will have a lot Sprout, sprout branch to weak strong. Early May to early June, the selection of branches in the middle of the lignified green branches of a single sprout for cleavage, and then wrapped with film strung the graft site, only exposed buds. Then irrigation to promote wound healing. Each root stock pick two live scion is appropriate, not to pick one
