在辣椒的一生中，落叶可分为两大时期，即苗期与结果期。苗期落叶主要是３月中下旬及４月初（指保护地生产的辣椒），当秧苗由苗床移入保护地后数天，可能引起大量的落叶。结果初期，在５月中下旬及６月上旬，每逢雨后初晴即可发生落叶，且叶子多属青叶，叶片上无明显的症状。 In pepper’s life, the leaves can be divided into two major periods, namely the seedling stage and the result period. Seedling deciduous leaves are mainly in late March and early April (refers to the production of pepper), when the seedlings from the seedbed into the protected area after a few days, may cause a lot of deciduous. As a result, deciduous leaves appeared early in mid-late and early June in early May and early June, respectively, and leaves were mostly green leaves with no obvious symptoms on the leaves.
