Red-maple-leaf-color redder method

Abstract

The invention belongs to the technical field of plant growth regulator application, and provides a red-maple-leaf-color redder method. The red-maple-leaf-color redder method includes the steps of (1)growing period topdressing, wherein topdressing is carried out on red maple trees 2 times to 3 times in April to July, and the applying amount of topdressing every time is 2 L / grain to 4 L / grain; (2)autumn coloring, wherein a coloring agent is sprayed to red-maple-leaf surfaces one time every 10 days to 15 days in August to October till at least one water drop exists in the front faces and the back faces of red maple leaves; (3) color keeping for delaying leaf abscission, wherein from the end of October to mid November, a color keeping agent is sprayed to the red-maple-leaf surfaces one timeevery 3 days to 5 days till the at least one water drop exists in the front faces and the back faces of red maple leaves, and spraying is continuously carried out 5 times or above. According to the red-maple-leaf-color redder method, time that the red maple leaves are colorful and lasting in late autumn can be effectively prolonged, and the condition can be commonly kept for 15 days to 20 days orabove.

Description

Problems solved by technology

[0003] With the vigorous development of agricultural and forestry eco-tourism, eco-tourism for viewing red leaves in autumn has also become a fashion, and has become a major industry to increase rural and villager economy. Affected by climate (light, temperature), autumn red is far less bright and lasting than that in the north. It often turns red-yellow or withered yellow before the leaves fall off in autumn and early winter, and falls off in less than 5-6 days, which makes people wonder. The ornamental effect of the red maple is disappointing, which affects the development of ecotourism and the income of the local economy
