在葡萄生产中,架式和方向是决定产量的一个重要因素。葡萄架式很多,方向各异,有的根据地形,有的根据风向气侯,有的按照习惯。但哪个方向的架式较好呢?据了解,在北方广大地区,向东、东北,或向北倾斜的葡萄架比较好,向南倾斜的葡萄架不好,在生产中应尽量少采用。大家知道,葡萄是喜光植物,光照对葡萄生长结果都有很大影响。叶片光合作用强度是随太阳辐射强度的增加而增加的。光照不足时,太阳辐射热效率低,光合强度小,制造营养少,因而葡萄枝蔓
In grape production, shelving and orientation are an important factor in determining yield. Many grape-style, different directions, and some according to the terrain, and some according to the wind climate, and some in accordance with the habit. However, in which direction is the frame better? It is understood that in the vast northern regions, eastward, northeast, or northward tilt of the grape is better, south slope of the grape is not good, should be used in production as little as possible. We all know that grapes are hi-light plants, light on the grapes have a great impact on the results. Leaf photosynthesis intensity increases with the increase of solar radiation intensity. Lack of sunlight, low thermal efficiency of solar radiation, photosynthetic intensity of small, less nutritious, and thus grape vine
