Problems solved by technology

[0003] The problem addressed by the present invention is: the traditional control method of catkins is divided into physical and chemical methods, the physical method mainly adopts the method of collecting catkins, reduces the floating of catkins, has a small range of treatment, and treats the symptoms but not the root cause; the chemical method adopts injecting inhibitors on willows, and the cost is low. High, slow to take effect, damages willows

Abstract

The invention discloses a method for reducing willow catkins, and is characterized by comprising the following aspects: before blooming, applying a germination inhibitor to the root of a willow, wherein the germination inhibitor comprises the following components: triadimefon, salicylic acid, ethanol, betaine, ammonium chloride, potassium dihydrogen phosphate, boric acid, manganese chloride, sodium molybdate, and iron sulfide; during the blooming period of the willow, spraying a flowering inhibitor, wherein the flowering inhibitor comprises the components of water, gibberellin, ethanol, thiophanate methyl, zinc nitrate, manganese chloride, calcium acetate, magnesium chloride, boric acid and potassium dihydrogen phosphate, promoting female flowers to be converted into male flowers or inhibiting flower growth, and lowering the flowering rate; using a willow fruiting inhibitor to block an ethylene action mechanism and inhibit fruit ripening so as to reduce the ripening ratio of catkin fruits.

Description

technical field [0001] The invention belongs to the technical field of tree prevention and control, and in particular relates to a method for reducing willow lint. Background technique [0002] Willows are widely planted in the south and north of my country. With their graceful and soft beauty, willows add scenery to landscape gardens. While adding color to people, it also brings troubles to our daily life. The poem "Crazy catkins dance with the wind, frivolous peach blossoms chase water", is exactly the situation that Tang Dynasty poet Du Fu described the situation of catkins flying all over the sky. From ancient times to the present, every year 4 From April to May, it has become an annual routine for catkins to fly all over the sky. Catkins are the seeds of willow trees, which are the fruit after the female flower matures. There are white hairs on the seeds, which are spread by the wind. Catkins have many hazards, such as catkins, which can carry various infectious virus...
