Red maple leaf autumn advanced (timed) and positioned coloring physical method

Abstract

The invention relates to a red maple leaf autumn advanced (timed) and positioned coloring physical method. The red maple leaf autumn advanced (timed) and positioned coloring physical method specifically comprises cutting off the vein of a leaf on the side of a planned coloring area, which is close to a petiole, or breaking off the petiole, then spray-applying a mixture liquid of 5-8 g / L of boric acid and 30 g / L of saccharose 15 d before a set coloring time. Chlorophyll of the vein / petiole controlled area is degradated gradually, and 15 d later, the red color of matters mainly contained in the leaf such as anthocyanin can be expressed, so that effects of advanced (timed) and positioned coloring of red maple leaves can be achieved. The red maple leaf autumn advanced (timed) and positioned coloring physical method is simple in operation and easy to grasp; the appropriate time of cutting off the vein is autumn, which is the later growth stage of red maple and has little influence on growth of the red maple, so that the autumn coloring period of the red maple leaves can be advanced, the foliage period of the red maple can be accurately controlled, the ornamental value of the red maple can be enhanced, and especially accurate coloring can be achieved.

Description

[0001] Technical field: [0002] The invention relates to a study on the mechanism of leaf color transformation of plants, in particular to a method for early (timing) positioning and expression of maple leaf color, which is a physical method for precisely controlling the color change of maple leaves. [0003] Background technique: [0004] Acer safflower is native to southern and eastern Canada and most of the United States. The maple safflower has large leaves, nearly the size of an adult's palm, and bright leaves. It is widely used in landscaping. The front of the newly born leaves of the red maple is reddish, and then turns green until dark green, and the back of the leaves is gray; if no physical factors are added, the autumn leaves change from green to yellow or red under natural conditions, which is a classic color. Street trees. [0005] The Agricultural Engineering Research Institute of Anhui Academy of Agricultural Sciences introduced Acer safflower in 2006 and carri...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved in the present invention is to aim at the disadvantages of Acer safflower autumn leaf color expression time is late, it is difficult to artificially control, the duration is short, and the color is not good. Under the premise of normal growth, by cutting off the veins of the maple leaves or breaking off the petioles, the time of autumn discoloration can be advanced, and the position and time of discoloration can be precisely controlled, so that it can be discolored at the planned time and position, and redness can be improved. The Ornamental Value of the Autumn Leaves of Acer japonica
