我们知道,柑桔叶片是进行光合作用。制造有机养分的主要器官,也是养分交换、运转,贮存的主要器官。叶片中某些营养元素的含量与柑桔生长、结实有着良好的相关性。叶分析技术就是根据这个原理,通过化学分析方法,了解不同生育期的叶片中所含的养分数量、种类及动态变化,来指导施肥的一种技术,又叫营养诊断技术。通过叶分析,能及时了解柑桔树养分的盈缺情况,及时矫正可能出现的元素缺乏症或过多症;同时可了解土壤中元素的增益和颉顽效应。从 We know that citrus leaves are photosynthetic. The main organ that makes organic nutrients is also the main organ for nutrient exchange, operation and storage. Leaf nutrient content of some citrus growth and fruiting has a good correlation. Leaf analysis is based on this principle, through chemical analysis methods to understand the different growth stages of the leaves contained in the number of nutrients, species and dynamic changes to guide fertilization of a technique, also known as nutrition diagnosis techniques. Through leaf analysis, we can understand the citrus tree nutrient surplus in time, and timely correction of possible elemental deficiency or excessive disease; at the same time can understand the soil elements of gain and Jie Zhu effect.
