黑奥林、巨峰、藤稔等大粒、鲜食优良葡萄,采用传统的硬枝扦插法育苗,大多是先发芽后生根,萌发的嫩芽常因水分、养分供应不上而枯萎。即使成活,早期生长也十分缓慢,致使苗木不壮,成苗率低。湖南省邵阳县岩口铺镇的县级科技示范户、“葡萄大王”李学军,通过多年试验,探索出用电热毯对葡萄插穗进行催根育苗的好方法。用此法苗木发根率达90%以上,且长得粗壮,移栽后生长快。他的经验如下: 电热毯温床的制作:将从商店购回的单人电热毯用新塑料薄膜(不能用地膜)包2～3层,使电热毯四周不能进水,以
Black Aolin, Kyoho, Fujimi and other large grains, fresh grapes, grapes, the use of traditional hardwood cutting nursery, most of the first germination after the root, the germination of the bud often due to moisture, nutrient supply and withered. Even survive, early growth is also very slow, resulting in seedlings are not strong, low rate of seedlings. Through the years of experimentation, county-level scientific and technological demonstration households at “Iwakura” and “Kyojiyoji” of Iwakuni Town in Shaoyang County, Hunan Province, have explored a good way to cultivate grape cuttings with electric blankets. With this method seedling hair root rate of 90% or more, and grow thick, fast growth after transplanting. His experience is as follows: Electric blanket hot bed production: The single purchased from the store blanket with a new plastic film (not with film) package 2 to 3 layers, so that the blanket can not be around the water to
