在水果王国—美国的加州,葡萄不仅一年可以两收,甚至还能三收。他们主要是根据葡萄极善形成花芽的特性,采用对新梢二次摘心、三次修剪的新技术。当早春第一次结果的枝梢长到10—15节时,进行第一次摘心,使顶端的芽迅速萌发生长,再生枝梢暂时被抑制。因为节间短,则成熟快,所以当新梢表面变褐时,芽内的花房即已形成。这时,乘在形成花芽的枝梢的芽尚未进入休眠前,可进行第一次修剪,并留下2—4个芽,此芽萌发后即为第二
In the fruit kingdom - California, USA, grapes can not only be collected twice a year, but also three times. They are mainly based on the grapes to form flower buds very good characteristics, the use of the second tip of the shoots, trimming the new technology. When the first results of the early spring branches grow to 10-15 knots, the first topping, so that the top of the rapid germination and growth buds, regenerative shoots temporarily inhibited. Because internodes are short, they mature quickly, so when the surface of the shoot is brown, the flower field in the shoot is formed. At this time, the shoots on the branches forming the flower buds have not yet been put into dormancy, the first pruning can be performed and 2-4 buds are left behind, and the buds are the second
