茶园叶面积指数是指叶片总面积与土地面积的比值,是反映茶树留养程度、光合面积的一个指标,它的大小直接关系到茶树的生长。通过它的测定可以推导茶园的理论生产水平,也是我们确定采摘、修剪和肥培管理等技术措施的依据之一。其测定方法有很多种,但考虑到便于生产实践中运用,这里选择一种测定比较容易,也是目前比较普遍采用的一种方法,向大家介绍如下: The leaf area index of tea plantation refers to the ratio of the total area of ​​leaves to the area of ​​land. It is an index reflecting the degree of keeping of tea tree and photosynthetic area. Its size is directly related to the growth of tea tree. Through its determination, the theoretical production level of tea plantations can be deduced, which is also one of the bases on which we determine the technical measures of picking, pruning and fertilizer management. There are many ways to measure it, but taking into account ease of use in production practice, it is easier to choose a measurement here, but also a more commonly used method to introduce to you as follows:
