Abstract

The invention relates to a method for controlling sycamore catkins, and belongs to the technical field of environmental protection. The method is as follows: from late March to early April, inject the medicine on the main branches of Platanus australis with a diameter greater than 20 cm, the injection location is the base of the branch, and the number of injections is once; The number of injections is 1 time; the agent is one of ethephon, 2,4-D or miRNA agomir-ETP1 or a mixture of two or more in any proportion. This method can effectively solve the deficiencies in the technology of controlling the flotation of sycamore in the prior art. The method is simple to operate, has quick results, and the fruit drop rate is as high as 95.98%. Restoration, to ensure the shading effect before the arrival of summer.

Description

technical field [0001] The invention relates to a method for controlling sycamore catkins, and belongs to the technical field of environmental protection. Background technique [0002] Platanaceae is a large deciduous tree of the Platanaceae family, up to 35 meters high, with spreading branches and a broad crown. There are three kinds of sycamores planted or introduced in my country: one-ball sycamore (Platanus occidentalis), two-ball sycamore (Platanus acerifolia), and three-ball sycamore (Platanus orientalis). Platanus not only grows rapidly, reproduces rapidly, has strong adaptability and stress resistance, but also has tall trunks, lush branches and leaves, and can absorb a large amount of dust in the air. Therefore, it has become an important street tree and landscaping tree species in large and medium-sized cities in my country. Platanus also has high economic value: its wood is a good material for making furniture, and its branches are also ideal materials for the cu...
