Problems solved by technology

In addition, the sycamores in most cities are already big trees. To graft and change branches, the branches must be cut off first. Grafting small branches with few or no fruits is not easy to succeed on old trees. Even if it succeeds, as the grafted branches grow If the grafting is not strong, there will still be a risk of broken branches hurting pedestrians and cars in severe windy weather in the future
In addition, the workload is heavy, the cycle is long, and there is a long gap period, which is difficult for the public to accept
In recent years, breeding male poplars is also a way, but there is also the problem that existing old trees cannot be regenerated

Embodiment 1

[0017] First measure the diameter of the plane tree, and determine the dosage according to the diameter. Select plane trees with diameters at breast height of 10, 15, 20, 25, 30, 35, 40, 45, and 50 cm respectively, use a mixture of plant growth regulators (glyphosate and ethephon at a weight ratio of 3:1), and add no Bacterial water preparation concentration is 40% mixed plant growth regulator mother liquor, dosage is respectively taken 6, 8, 12, 15, 17, 19, 22, 25, 28ml mother liquor, then add sucrose 1g and urea 0.5g respectively, or Sucrose 1g and ammonium bicarbonate 1g, add water to 100ml, the concentration of preparation plant growth regulator is respectively 2.4%, 3.2%, 4.8%, 6%, 6.8%, 7.6%, 8.8%, 10%, 11.2% of plant growth growth inhibitors.

[0018] The above-mentioned plant growth and development inhibitors are injected into the infusion bag respectively, and the infusion bag is hung on the place where the diameter at breast height is 10, 15, 20, 25, 30, 35, 40, 45,...

Embodiment 2

[0020] First measure the diameter of the poplar tree, and determine the dosage according to the diameter of the poplar. Select poplars with diameters at breast height of 15, 20, 25, 30, 35, and 40 cm respectively, use a mixed plant growth regulator with a weight ratio of glyphosate:ethephon of 1:1, and add sterile water to configure a concentration of 40%. Mix the mother liquor of the plant growth regulator, take the mother liquor of 8, 12, 15, 17, 19, and 22ml for the dosage, add water to 100ml, and prepare the concentration of the plant growth regulator to be 3.2%, 4.8%, 6%, 6.8%, respectively. 7.6%, 8.8% plant growth and development inhibitors.

[0021] Inject the above-mentioned plant growth and development inhibitors into infusion bags respectively, and hang the infusion bags on the branches of poplar trees with diameters at breast height of 15, 20, 25, 30, 35, and 40 cm, which are more than 1 meter away from the trunk, and then place them at a distance of 0.4-1.0 from th...

Embodiment 3

[0023] Select 30 Platanus trees with a DBH of 30cm, use glyphosate, and the ratio of glyphosate:ethephon is 9.7:0.3, 10:1, 5:1, 2:1, 1:1, 1:2, 1:5, 1 : the mixed plant growth regulator of 9, adding sterile water configuration concentration is the plant growth regulator mother liquor of 40%, gets 15ml mother liquor, adds water to 100ml, the preparation plant growth regulator concentration is the plant growth and development inhibitor of 6%.

[0024]The above-mentioned plant growth and development inhibitors were injected into the infusion bag respectively, and the infusion bag was hung on the branches of 30 sycamores at a distance of more than 1 meter from the trunk, and then drilled with an electric drill at a distance of 0.4-1.0 meters from the trunk. 5cm, diameter 1.0-2.0ml, finally insert the needle into the hole, open the regulating valve of the infusion bag, you can adjust the size of the switch according to your needs, for example, when the temperature is high and the tra...

Abstract

The invention discloses a plant growth and development inhibitor. The plant growth and development inhibitor comprises the following components in percentage by mass: 0.1 to 40 percent of plant growth regulator and the balance of water, wherein the plant growth regulator comprises glyphosate. The invention also discloses application of the plant growth and development inhibitor in treatment of pollution of platanus acerifolia fruit fur or populus sp. fruit fur. By combining the plant growth and development inhibitor with a punching bag infusion method, fruit fur pollution is treated, effects can be achieved when the inhibitor is used 15 days later, the growth and the development of female fruits which are grown in the same year are inhibited, fruit spheres are shrunk, and partial fruit spheres fall; and the development of the fruits is inhibited, the fruit fur is nearly not developed, and the control rate can reach about 80 percent, so that the inhibitor has a remarkable effect.

Description

technical field [0001] The invention relates to a plant growth and development inhibitor and application thereof, in particular to a plant growth and development inhibitor for controlling the pollution of sycamore or poplar fruit hairs. Background technique [0002] Platanus acerifolia (Platanus acerifolia) is an excellent variety of one of the backbone tree species selected by the National Afforestation Committee, and has a long history of cultivation in my country. Platanus is one of the excellent street tree species in urban greening, and it is currently planted in Shanghai, Hangzhou, Nanjing, Wuhan, Zhengzhou, Jinan, Qingdao, Hefei, Nanchang, Changsha and other cities. According to preliminary statistics, the number of sycamores in the country is more than 1 million. The main characteristics of Platanus are tall trees, large shade, strong adaptability, resistance to pruning, easy to shape, easy to reproduce, fast growth and so on. The economic use of plane tree has gra...
