位于辽宁省北纬41°地区的大洼县,露地栽培葡萄生长期仅165天左右,当年扦插当年结果在自然条件下不可能的。我们改变外界生长条件,在1979年利用温室栽培,使生长期不受外界气候的限制,并提供生长所需要的养分和水分,精细管理,节约树体营养,促使付梢上的夏芽分化完全,形成花序,结果当年扦插,当年结果。试验的技术操作情况:1979年4月14
Located in Dawa County, Liaoning Province, 41 ° north latitude, open-field cultivation of grape growth period of only 165 days or so, when the year cuttings results in natural conditions impossible. We changed the external growth conditions, the use of greenhouse cultivation in 1979, so that the growth period from the outside climate constraints, and provide the necessary nutrients and water growth, fine management, conservation of tree nutrition, to promote the bud on the summer bud differentiation , The formation of inflorescences, the result of cutting the year, the year results. The technical operation of the test: April 1979,
