Example 4

The leaf color-changing solution of the embodiment 1, wherein the trace elements are one or more of magnesium, zinc, copper, manganese, boron, iron, sulfur and molybdenum. The trace elements contained in the leaf color-changing solution prevent the trees from being ill due to the lack of the trace elements, and the trees can grow healthier while the leaves change color.

Example 5

The embodiment provides a method for changing color of tree leaves, which comprises the following steps:

s1, selecting trees with trunk diameters of more than 10 cm as trees to be discolored;

s2, scraping a plurality of old barks on the trunk of the tree to be discolored at intervals in the horizontal direction by using a scraping shovel to respectively expose new barks, and drilling liquid injection holes at positions where the new barks are exposed;

s3, respectively inserting an injection needle into each injection hole;

s4, injecting the leaf color-changing solution in the embodiment 2 or 3 into each liquid injection hole through the liquid injection needle head by means of an infusion bag or a pressurized gas cylinder (suspending nutrient solution of the infusion bag on a trunk by an iron wire 1.3 meters above the punched hole, and inserting the infusion apparatus when the liquid flows out);

and S5, after liquid injection is finished, pulling out the liquid injection needle head, spraying a green plant bactericide and a green plant repair paste on each liquid injection hole, and plugging and binding the liquid injection holes.

The leaf color changing method is suitable for being carried out in the middle of April, when the trees to be subjected to color changing are selected, the trees with complete and big and leafy leaves are selected, and the trees with the grown leaves are selected. After the injection of the leaf color-changing solution is finished, the leaves generally change color for 1-3 days and can turn into red or blue, and the leaves generally turn back to the original green after 15-20 days after the leaves are all color-changed.

The leaf method of discolouing of this embodiment only need bore at the trunk and get several and annotate the liquid hole, can conveniently pour into the trunk with leaf solution of discolouing, and annotate the liquid and finish the back every it is green to plant germicide and green restoration cream and the shutoff of planting to annotate liquid hole, avoid annotating liquid hole department and take place the infection and make trees sick, leaf method of discolouing can make trees take place the leaf and discolour under the prerequisite of healthy growth, and the discolour fast, can obtain the leaf of better sight very fast.

Example 6

The leaf color-changing method according to embodiment 6, further comprising the following steps after step S5:

s6, after the leaves are changed to be close to the original colors again, inserting a hole expanding drill bit into the liquid injection hole for expanding the hole, and continuously injecting the leaf color-changing solution according to the claim 2 or 3 into the expanded liquid injection hole;

the diameter of the hole expanding drill bit is 0.5mm larger than that of the last drilling drill bit;

the diameter of the finally obtained liquid injection hole is not more than 5 mm.

After the injection of the leaf color-changing solution is finished, the leaves generally change color for 1-3 days and can turn into red or blue, and the leaves generally turn back to the original green after 15-20 days after the leaves are all color-changed. Therefore, the leaf color changing method of the embodiment can include the following multiple liquid injection processes:

injecting liquid for the first time: drilling holes through a drilling bit, and injecting a leaf color-changing solution into the liquid injection holes, wherein the diameter of each liquid injection hole is 2.5-3mm, the leaves change color about 1-3 days after liquid injection, and the leaves turn green again after 15-20 days;

and (3) secondary liquid injection: reaming is carried out through a reaming bit, the diameter of the reaming bit is 0.5mm larger than that of the last drilling bit, a leaf color-changing solution is injected into the reamed liquid injection hole, the leaves change color about 1 to 3 days after liquid injection, and the leaves change back to green after 15 to 20 days;

and (3) injecting liquid for the third time: reaming is carried out through a reaming bit, the diameter of the reaming bit is 0.5mm larger than that of the last reaming bit, a leaf color-changing solution is injected into the reamed liquid injection hole, the leaves change color about 1 to 3 days after liquid injection, and the leaves turn green again after 15 to 20 days;

……

until the leaves turn yellow in autumn, the leaves of the yellow leaves are cut off, and the diameter of the hole expanding drill bit is 0.5mm larger than that of the last hole expanding drill bit each time.

The leaf color changing method can maintain the color of the leaves after color changing, such as red or blue, by injecting the leaf color changing solution for multiple times, the method is simple and scientific, the leaves can be maintained in red or blue conveniently, and the trees can grow healthily in the whole process.
