富士苹果具有枝条易光秃的特性,幼树期光合面积形成缓慢,所以增加枝量是富士幼树期管理的主要内容。主要措施如下: 1、冬剪时短截:短截修剪法在现代果树修剪中应用愈来愈少,但作为增枝的手段仍效果很好,在幼树期,对缺枝严重部位选生长健壮的枝在中部饱满芽处短截,可抽生2—3个长枝,3—5个短枝,有利于填补空间,扩大光合面积,增加光合产物积累,有利于早结果,早丰产。 2、春季拉枝:在幼树枝量少时,可通过将枝拉平或使之下垂,将枝的顶端优势由枝梢顶端变为枝背,
Fuji apple has the characteristics of easy to bare branches, the young tree photosynthetic area formation is slow, so increasing the amount of branches is the main part of Fuji sapling management. The main measures are as follows: 1, short cut in winter shear: short cut pruning method in the application of modern fruit tree pruning less and less, but as a means of increasing branches is still very good at sapling, Sturdy branches in the middle full bud short cut, 2-3 branches can be sprouted, 3-5 short branches, is conducive to filling space, expanding photosynthetic area, increase photosynthetic product accumulation, is conducive to early results, early bumper crop. 2, the spring pull branches: the amount of young branches less, by pulling the flat or make it sag, the tip of the branches from the tip of the tip into branches,
