1叶果比法即每株树上的总叶片数与总果数之比。据研究表明,一个果实消耗的营养需要多少片叶子来供应有一定范围,果个越大,需要叶片的供应越多;反之愈少。因而既要保证果实有足够的营养供应其生长,又要保证有充足的营养形成下年够用的花芽及维持树体的生长势,一般认为盛果期鸭梨
1 leaf ratio method that is the total number of leaves per tree and the total number of fruit ratio. According to the study, how many leaflets are needed for the nutrition consumed by a fruit to supply a certain range, the larger the fruit, the more leaf supply is needed; Therefore, it is necessary to ensure that the fruit has sufficient nutrition to supply its growth, but also to ensure adequate nutrition to form the next year enough flower buds and maintain the growth potential of the tree, the general view that full-fruit pear
