不同黄瓜品种的摘心栽培效果

黄瓜摘心栽培 ,侧枝结果的多少很大程度决定产量高低 ,要选用侧枝萌发、生长和环境适应能力强的品种 ,侧枝以 2节摘心为宜 ,侧枝发生多和侧枝上的结果多的品种 ,其主茎叶片的光合成速率也较大 ,对于侧枝萌发少和生长缓慢的黄瓜品种 ,或者在栽培条件较差 ,侧枝发生及生长差时 ,宜适当提高主茎摘心节位 ,以确保着果节数。

Since yields are greatly effected by fruit sets on secondary stems lateral shoots budded, their growth and adaptability to environmental factors are necessary for choice of the variety.Secondary stems must be pinched at the second node . Varieties producing abundant secondary stems with high fruit sets showed high photosynthetic activities of the primary leaves. At the case of varieties producing less stems and in slow growth rates and of deteriorated lateral budding and their growth owing inadequate environments, it is necessary for ensuring numbers of nodes with fruiting to remove apical parts of primary stems at the high node positions.
