Abstract

The invention discloses a method for promoting discoloration of sapium sebiferum leaves in autumn to improve the appreciation effect of sapium sebiferum trees. The method comprises the following steps: selecting frondent sapium sebiferum trees of 3 year old or older, spraying a 6-BA aqueous solution before or after August 25th, after 6-10 days, spraying a mixed aqueous solution of ethephon and potassium sulfate monobasic to promote generation of anthocyanin so as to promote sapium sebiferum leaves to turn red, after 6-10 days, spraying an aqueous solution of citric acid and saccharose to enable the sapium sebiferum leaves to turn redder and prolong the red leaf period of sapium sebiferum trees. With adoption of the method, the red leaf period of sapium sebiferum trees is prolonged by more than one month on the premise of not affecting the normal growth of sapium sebiferum trees, the leaf color of sapium sebiferum trees is enabled to be bright red and pure, and the landscape effect is excellent. According to the invention, the operation is simple and convenient, and the method is used together with sterilization, deinsectization, greening and maintenance measures in late summer and early autumn, so that the cost is reduced.
