所谓个体内部的三种矛盾是指主茎生长与分蘖生长的矛盾,成穗分蘖生长与无效分蘖生长的矛盾以及营养生长与生殖生长的矛盾。小麦个体内部的上述三种矛盾,主要表现在植株内的营养物质(无机养料和有机养料,特别是碳水化合物)的分配转移和代谢作用上。对于这方面的规律,根据研究结果,归纳如下。一是小麦个体内部碳素营养分配的中心和生长中心是完全一致。这就是说,小麦植株的哪一器官、哪一部分生长越迅速,生活力越旺盛,营养物质就向它转移,保证对它的供应。二是小麦主茎与分蘖之间的磷和碳素养分可以 The so-called three internal contradictions refers to the main stem growth and tiller growth contradictions, spike tillering growth and ineffective tiller growth contradictions and vegetative and reproductive growth contradictions. The above three contradictions in wheat individuals are mainly manifested in the distribution, transfer and metabolism of nutrients (inorganic nutrients and organic nutrients, especially carbohydrates) in plants. For the law in this area, based on the findings, summarized as follows. First, the distribution center and growth center of carbon nutrition within wheat individuals are exactly the same. This means that the organ of wheat, which part of the plant grows more rapidly, the more viable vitality, nutrients to it to transfer, to ensure its supply. The second is between wheat main stem and tiller phosphorus and carbon nutrients can be
