Plant fruit thinning agent and plant fruit thinning method

Abstract

The invention discloses a plant fruit thinning agent, and belongs to the technical field of growth regulation of plants. The plant fruit thinning agent is technically characterized by comprising crudedrugs and additives, wherein the crude drugs are selected from one or multiple of clopidobenzuron, indoxylate, 6-benzyl-adenine, gibberellin, polytropazole, entotropazole, naphthylacetic acid, indolebutyric acid, 2,4-dichlorophenoxyacetic acid, triiodobenzoic acid, 2-chloroethyl trimethyl ammonium chloride, cycloheximide, chlorpropham, sulfonylurea herbicide, imidazolinone herbicide and triazolopyrimidine herbicide. The invention also discloses a use method of the plant fruit thinning agent. The use method comprises the following steps of diluting the agent to the concentration of 0.1 to 10gof crude drug per 1L within 1 to 50 days after flowering period of plant or during young fruit period, and spraying to the plant; or, injecting the agent into the plant trunk according to the dose of0.05 to 2g of crude drug per 1cm of diameter at breast height. The plant fruit thinning agent is used for thinning the fruits of the plants, such as ginkgo, ligustrun lucidum, mulberry tree, banyan tree and syzygium jambos, and the thinning effect is good.

Description

technical field [0001] The invention relates to the technical field of plant growth regulation, in particular to a plant fruit thinning agent and a plant fruit thinning method. Background technique [0002] Many street tree species in gardens are mainly used for viewing leaves. As an accessory product of street trees, the fruit has no actual economic value. On the contrary, the fruit falling will have an impact on the urban environment. The flying feathers cause disturbance to the people, and the fruits of plants such as privet privet, mulberry, alpine banyan and Putao will adhere to the road or vehicles and cause pollution. Especially the ginkgo tree that is widely used in my country has accounted for about 7% of the total amount of arbor and street trees in urban areas, and wherein the female plants account for a considerable proportion. When the female ginkgo plant reaches a certain age, the amount of fruit will increase sharply. The aril of the fruit has a foul smell an...

AI Technical Summary

Problems solved by technology

When the female ginkgo plant reaches a certain age, the amount of fruit will increase sharply. The aril of the fruit has a foul smell and a certain degree of stickiness. Therefore, after the fruit matures and falls to the ground, the aril is attached to the ground after being rolled by vehicles and trampled by pedestrians. Pavement, difficult to clean and smelly, has a great negative impact on air quality and sanitation

At the same time, too much fruiting of female ginkgo plants will consume a large amount of tree nutrients, resulting in weak growth of the tree body, and significantly increasing the incidence of ginkgo scorch, resulting in a 94.2% incidence rate of female ginkgo plants in Beijing, which is much higher than 37.4% of male plants (Zhang Mingqing , Yang Guodong. 2002. Analysis on the Causes of Prunella Kult of Ginkgo Trees. Meteorological Science and Technology, 30(5):318-320.), which seriously affects the growth and ornamental value of Ginkgo trees
