Embodiment Construction

[0009] A method for promoting the discoloration of Chinese tallow tree leaves in autumn and improving the ornamental effect of Chinese tallow tree,

[0010] (1) Select Chinese tallow tree that is more than 3 years old and grow luxuriantly, and spray the foliage with agent I, which uses 6-BA (6-benzylaminoadenine) aqueous solution with a concentration of 100-400mg / L;

[0011] (2) After 6-10 days, spray agent II to promote the formation of anthocyanins and make the leaves turn red. Agent II uses a mixed aqueous solution of ethephon and potassium dihydrogen sulfate, and the concentration of ethephon is 300-600mg / L. The concentration of potassium dihydrogen sulfate is 1~3g / L, and the pH value of the mixed aqueous solution is 5~5.5; after spraying, the leaves begin to turn red rapidly;

[0012] (3) After another 6-10 days, spray agent III, which is an aqueous solution of citric acid and sucrose, in which the concentration of citric acid is 1-3g / L, and the concentration of sucrose i...

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. With the improvement of the appreciation level of people, the requirements of people for landscape architecture is also raised; therefore, the situation that the appreciation effect of fiery-red sapium sebiferum leaves in autumn is fully expressed has excellent prospects on the premise of not changing trees or adopting other methods with much consumption.

Description

technical field [0001] The invention relates to a finishing technology of garden landscape, in particular to a method for promoting the color change of Chinese tallow tree leaves in autumn and improving the ornamental effect of Chinese tallow tree. Background technique [0002] Chinese tallow tree is an autumn color-changing tree species with high ornamental value, which can turn into bright red, purple red and yellow after the National Day. However, due to the different sources of tree species used in landscaping, coupled with the impact of climate change and human activities, the autumn leaf color and red leaf period of Chinese tallow tree become shorter or the leaf color is not pure, which greatly affects the viewing effect of Chinese tallow tree. Contents of the invention [0003] The technical problem to be solved in the present invention is to address the deficiencies of the prior art, and propose a method that can make Chinese tallow tree leaves bright red and pure...
