Inhibitor for plant flying-batt and its use

Abstract

The present invention provides a plant flying catkin inhibitor. It is characterized by that its raw material composition includes gibberellin, naphthaleneacetic acid and indolebutyric acid. Besides, it also can include solvent and water. Said invention also provides its preparation process and application method.

Description

technical field [0001] The invention relates to a plant catkin inhibitor and its application, in particular to a willow catkin pollution inhibitor and its application in preventing and controlling willow catkin pollution. Background technique [0002] Poplar is the general term for the plants of the genus Populus in the family Salicaceae, and willow is the general term for the plants of the genus Salix in the family Salicaceae, which are widely distributed in the world. [0003] China is the origin center of poplars and willows. There are 53 species of poplars and 257 species of willows native to China, accounting for about half of the species of poplars and willows in the world. Because poplar and willow have many advantages such as wide ecological adaptability, stress resistance and vitality, fast growth, easy reproduction, tall tree, beautiful tree shape, large shading area, and good effect, they have become urban greening, farmland shelterbelt construction, The backbone...

Problems solved by technology

[0008] Second, it has certain hazards to public safety, traffic safety and public facilities

[0014] The first method: because there are a large number of female willow plants in the city, and they are in the prime of plant growth and the period when the ecological benefits are most significant, cutting down and eliminating these female willow plants will greatly damage the original ecological environment and environment of the city. In the green space landscape, the replaced trees are difficult to form the greening and shading effects of the original trees in a short period of time, which will bring incalculable losses to the urban greening cause and seriously reduce the ecological benefits of urban greening. Huge manpower and financial resources have been invested, making it unrealistic to eliminate all female willow plants in a short period of time

[0015] The second method: the willow high-level grafting technique needs to cut off the canopy of the original female willow tree, and graft young male branches on the main branch to change the female tree into a male tree, which requires grafting professionals with a high level of technology to operate , and there are certain hidden dangers in production safety

Higher grafting costs and high-level grafting of poplars will seriously damage the landscape effect of poplars, making them lose their tall and straight tree posture, and it is impossible to apply high-level grafting technology to poplars, which greatly limits the popularization and application of high-level grafting technology

[0016] The third method: the poplar female inflorescence thinning agent can make the poplar female inflorescence form a detachment layer at the base in advance, so that the female inflorescence falls off early before the catkins fly, but the effect of this agent on the poplar female inflorescence is only It is about 70%, and the application time and application technology are strictly required. Only when the female inflorescence of the poplar grows to 4-6cm can the pesticide be applied to achieve a good thinning effect. Too early application will greatly reduce the control effect. Effect, spraying too late will cause serious phytotoxicity and affect the normal growth of poplars; at the same time, the medicament will cause phytotoxicity to willows and other early-germinated broad-leaved plants (including ground cover plants, shrubs, etc.) under poplars, The negative effects of drugs are very prominent

The agent will form serious drift during the spraying process, causing secondary pollution to the air environment

The high cost of control and the limitations of the above technologies have greatly restricted the large-scale application of this agent

[0017] Due to the large technical limitations of the above three methods, it is impossible to apply them on a large scale in practice.
