葡萄在塑料营养袋内扦插繁殖,系应用上海农机研究所提供的电加温线为主要热源,在塑料薄膜罩小范围内增温,并在其它综合管理条件下,于1983年4月试验取得成功。该项育苗技术具有集约、快速、省工、省田的效果外,由于苗木的生育期提前3个月和移栽不伤根等优点,为葡萄栽培提早成形,早期丰产打下良好基础。 Grapes in plastic nutrition bags cutting propagation, the Department of Shanghai Agricultural Machinery Research Institute to provide the electrical heating as the main heat source in the plastic film cover a small area warming, and in other comprehensive management conditions, in April 1983 trial success. The nursery technology has the advantages of intensive, rapid, labor-saving and provincial performance. Because the seedling growth period is three months ahead of schedule and the transplanting does not hurt the root, etc., a good foundation for early viticulture and early yielding is laid.
