Problems solved by technology

However, due to the different sources of Liriodendron tree species used in the current greening gardens, coupled with the impact of different climate changes and human activities, the leaves of Liriodendron tend to show impure leaf colors in autumn, mixed leaf colors, and different chromaticity. One phenomenon greatly affects the ornamental effect of Liriodendron

Embodiment Construction

[0015] 1) Select Liriodendron tulipifera, which is more than 3 years old and grow luxuriantly, and spray the leaves with agent I, which is a mixed aqueous solution of forchlorfenuron with a concentration of 200-300mg / L and 100-200mg / L gibberellin;

[0016] 2) After 8-10 days, spray agent II on the leaves to promote the formation of flower color and turn red leaves. Agent II is a mixed aqueous solution of ethephon and phytoalexin. The concentration of ethephon is 300-600mg / L, which is suitable for plant protection. The concentration of phytoalexin is 3~5g / L, and the pH value of the mixed solution is 5~5.5. The adjustment of pH value is mainly realized by adjusting the concentration of ethephon and phytoalexin. After 3~5 days after spraying, the leaves can initially turn purple. ;

[0017] 3) After 6-10 days, spray agent III on the leaves. Agent III is a mixed aqueous solution of citric acid and sucrose, in which the concentration of citric acid is 3-5g / L and the concentration o...

Abstract

The invention discloses a method of prompting discoloration of tulip tree leaves in autumn. The method comprises following steps: spraying medicament I to tulip tree leaves; spraying medicament II to tulip trees again after 8-10 days and then spraying medicament III to tulip trees after 6-10 days. The medicament I is a mixed aqueous solution composed of forchlorfenuron and gibberellins. The medicament II is a mixed aqueous solution composed of ethephon and phytoalexin. The medicament III is a mixed aqueous solution composed of citric acid and saccharose.The method of prompting discoloration of tulip tree leaves in autumn has following beneficial effects: the method is easily operated; without affecting normal growth of tulip trees, tulip tree leaves can uniformly turn into fuchsia in autumn so that better sight-seeing effect is obtained; and better economic benefit is obtained.

Description

technical field [0001] The invention relates to the field of garden ornamental plant modeling. Background technique [0002] Liriodendron is an autumn color-changing tree species with high ornamental value. Its leaves can turn yellow or golden in early October, which is very ornamental. However, due to the different sources of Liriodendron tree species used in the current greening gardens, coupled with the impact of different climate changes and human activities, the leaves of Liriodendron tend to show impure leaf colors in autumn, mixed leaf colors, and different chromaticity. One phenomenon greatly affects the ornamental effect of Liriodendron tulipifera. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the prior art. Under the premise of not affecting the normal growth of Liriodendron, a method that can make the leaves of Liriodendron turn purple in autumn is proposed. The ornamental effect of catalpa. [0004] T...
