葡萄新梢在发育过程中,由于某些原因而成熟不良。这些枝不但难于形成良好的结果母枝,而且冬季很容易被冻死。笔者通过1995～1996两年的观察和试验,较好地解决了这一问题,现总结如下:一、新梢成熟不良的原因1.结果过多结果过多时,光合产物大部用于果穗(粒)生长,使枝梢营养不良。这是进入结果期的葡萄新梢不能成熟的最主要的原因。2.病虫危害由于受葡萄霜霉病、自腐病及葡萄二星叶蝉等的危害,而造成早期落叶,影响光合作用,使新梢成熟不
Grape shoot in the development process, due to some reasons and poor maturation. These branches are not only difficult to form a good parent, but also freeze easily in winter. The author through the 1995 ~ 1996 two years of observation and test, a better solution to this problem, are summarized as follows: First, the reasons for poor shoot maturity 1. Too many results When the results are too much, most of photosynthetic products for ear ( Grain) growth, malnutrition shoots. This is the most important reason why the new shoots in the fruiting season can not mature. 2. Pest damage due to the grape downy mildew, self-rot and grape two-leafhopper and other hazards, resulting in early deciduous, affecting photosynthesis, the shoot mature
