矿物质营养不仅能促进小麦茎叶生长,扩大光合作用面积,延长光合作用时间,而且也是光合作用器官进行活动的重要条件,如氮素是叶绿素和蛋白质分子的组成部分,磷是许多代谢过程的中间产物。肥料是小麦生长发育的物质基础。合理施肥不仅能满足小麦生长发育需要,而且有利于改善土壤? Mineral nutrition can not only promote stem and leaf growth of wheat, expand photosynthetic area, prolong photosynthesis time, but also important conditions for photosynthetic organs to perform activities. For example, nitrogen is a component of chlorophyll and protein molecules. Phosphorus is involved in many metabolic processes mid product. Fertilizer is the material basis for the growth and development of wheat. Rational fertilization can not only meet the needs of wheat growth and development, but also help to improve the soil?
