靠渗透压力吸水吸肥是柑桔具有的功能 ,从萌芽到越冬 ,都维持着渗透压力。渗透压力能把根部的养分提升到树冠顶端、枝条尖端 ,供给光合作用所需物质 ,维持新陈代谢正常水平。渗透压力树冠顶部、枝条顶端较强 ,养分流向集中在这些部位 ,加上光温条件充足 ,因而萌芽早 ,长势强 ,
Water absorption by osmotic pressure is the function of citrus, from the bud to the winter, are to maintain the osmotic pressure. Osmotic pressure can enhance the root of nutrients to the top of the canopy, branches tip, supplies the necessary materials for photosynthesis, to maintain the normal metabolism. At the top of osmotic pressure crown, branches top strong, nutrient flow concentrated in these parts, coupled with adequate light and temperature conditions, and therefore early budding, strong growth,
