Poplar and willow catkin inhibitor

Abstract

The invention provides a poplar and willow catkin inhibitor which can effectively inhibit poplar and willow catkins. The poplar and willow catkin inhibitor comprises polyacrylamide, fulvic acid, abscisic acid, brassinolide and forchior fennron. The raw materials are dissolved into a solvent, the medicament is sprayed onto tree crowns in a hyperbaric spraying mode, the validity period of each time of spraying can last for about one month, and if the growth cycle of the poplar and willow catkins this year is long, a second time of spraying can be conducted one month later. The poplar and willow catkin inhibitor overcomes various defects of poplar and willow catkin inhibitors in the prior art, and well overcomes the defects of urban poplar and willow greening.

Description

technical field [0001] The invention belongs to the field of urban landscaping, and specifically relates to a willow catkin inhibitor that can effectively inhibit willow catkins. Background technique [0002] Poplars and willows are tree species widely planted in the north. Among them, poplars are mostly used as protective forests and greening. Because of their fast growth, poplars have been favored by many people, and they are more distributed in the middle and lower reaches of the Yellow River. The largest poplar species is Populus tomentosa, especially in Henan, and a small amount is also planted in Shandong and Beijing. Willow is a native tree species in my country. It belongs to a plant with a wide ecological range. It has wide adaptability to the environment. It likes light, humidity, and cold. There are many advantages such as good shade effect, and more willow trees are used for greening in cities. [0003] Although poplars and willows add a lot to urban greening, t...

Problems solved by technology

[0003] Although poplars and willows add a lot to urban greening, they also have certain disadvantages. After the female poplars and willows mature, they will produce more catkins every spring, which usually lasts for more than a month. The environment has a certain impact, and the catkins flying all over the sky can easily enter the human respiratory tract and cause respiratory diseases. At the same time, it may cause allergies and other diseases, posing a threat to human health

[0004] The drug "Yihua No. 1" developed by the Beijing Academy of Garden Sciences to inhibit catkins has been circulated in the market, but the cost of the drug is relatively high, and the trees must be injected a year in advance to achieve the corresponding effect , and the drug hole after injection is very prone to plant diseases and insect pests. In addition, after the drug is used, some trees appear to grow wildly, dead branches, etc.
