一、培养中庸偏强的树势 中庸树的叶绿素、可溶性固形物含量及果实着色指数均比虚旺树、弱树高。骨干枝、结果枝二者粗度比为25％时,结出的果实个头大,着色好;二者粗度比大于30％时,果实个头虽大,但着色差。骨干枝、结果枝二者长势均弱,不仅果个小,而且着色不正常。因此,保持中庸健壮的树势,对于生产红富士全红果是至关重要的。 First, to cultivate a strong middle-class tree moderate chlorophyll, soluble solids content and fruit coloration index than the virtual tree, weak tree high. Backbone branches, the results of the twig when the ratio of the thickness of 25%, the resulting fruit big head, good coloring; two rough than 30%, the head of a large, but poor color. The backbone of the branches, the results of the growth of both branches are weak, not only a small fruit, and coloring is not normal. Therefore, to maintain a healthy and vigorous tree vigor is crucial for the production of red Fuji red fruits.
