A kind of plant growth and development inhibitor for controlling fruit hair pollution and application thereof

Abstract

The invention discloses a plant growth and development inhibitor for controlling fruit hair pollution and an application thereof. The plant growth and development inhibitor comprises a plant growth regulating agent, water and adjuvant, wherein the plant growth regulating agent comprises glyphosate, and the adjuvant comprises at least one of a nutritional ingredient and an adhesive. According to the plant growth and development inhibitor disclosed by the invention, the glyphosate is utilized to inhibit decelerated division of megasporocyte and microsporocyte, the development of pollen grains as well as the formation and development of ovules, so that the formation of fruit is inhibited, fruit hair is reduced obviously, and is even eradicated, so as to achieve the effect of controlling the fruit hair pollution. Treatment concentration of medicaments can be reduced effectively, consumption of the medicaments is reduced, and pollution risk caused by tree crown spraying is reduced. The plant growth and development inhibitor disclosed by the invention is combined with a spraying method to control the fruit hair pollution, the desired effect can be achieved around 30 days after the application of the medicaments, female flowers are reduced, the growth and development of female fruit grown in the same year are inhibited, fruit balls are reduced, and the general effect can reach 85%, and the plant growth and development inhibitor disclosed by the invention has an effect of obviously reducing the fruit hair pollution.

Description

technical field [0001] The invention relates to a plant growth and development inhibitor and an application thereof, in particular to a plant growth and development inhibitor for controlling sycamore or poplar fruit hair pollution and an application thereof. Background technique [0002] There are three kinds of sycamores: one-ball sycamore or American sycamore (Platanus occidentalis L.), two-ball sycamore or British sycamore (Platanus acerifolia (Aiton) Willd.) and three-ball sycamore or French sycamore (Platanus orientalis L.). It is an excellent variety of one of the backbone tree species selected by the National Afforestation Committee, and has a long history of cultivation in my country. At present, it is planted more in Shanghai, Hangzhou, Nanjing, Wuhan, Zhengzhou, Jinan, Qingdao, Hefei, Nanchang, Changsha and other cities. According to preliminary statistics, the number of sycamores in the country is more than 1 million. Platanus is one of the excellent street tree ...

AI Technical Summary

Problems solved by technology

In addition, the sycamores in most cities are already big trees. To graft and change branches, the branches must be cut off first. Grafting small branches with few or no fruits is not easy to succeed on old trees. Even if it succeeds, as the grafted branches grow If the grafting is not strong, there will still be a risk of broken branches hurting pedestrians and cars in severe windy weather in the future

In addition, the workload is heavy, the cycle is long, and there is a long gap period, which is difficult for the public to accept

In recent years, breeding male poplars is also a way, but there is also the problem that existing old trees cannot be regenerated
