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 ...

[0029] The plant growth regulator treatment designed in the test is glyphosate alone and the compound treatment with ethephon in the weight ratio of 20:1, 10:1, 5:1 and 4:1. The compound can be treated with the existing The method is to add auxiliary agents and water known to those skilled in the art to make water preparations, take 490 grams of glyphosate potassium salt or the composition of glyphosate potassium salt and ethephon in proportion, add about 100 grams of auxiliary agents (α - 40 grams of sodium alkenyl sulfonate, 55 grams of alkyl glycosides, 5 grams of tea saponin and a small amount of antifoaming agent), water is mixed with 1 liter of medicinal solution, add urea 100g\sucrose 100g (add 200g nutritional labeling in 1L medicament, The weight ratio of urea to sucrose is 1:1), dissolved in 1000 liters of tap water, spraying 30 trees with each agent ratio, spraying with a garden spraying device, the amount of spray can be completely sprayed, and it is not suitable to...

[0032] The plant growth regulators in the experimental design were treated with glyphosate alone and with ethephon at 20:1, 10:1, 5:1 and 4:1. Take 490 grams of glyphosate potassium salt or glyphosate The compound composition of phosphine potassium salt and ethephon in proportion, adding about 100 grams of additives (40 grams of sodium α-alkenyl sulfonate, 55 grams of alkyl glycosides, 5 grams of tea saponin and a small amount of defoamer), water Prepare 1 liter of medicinal solution, add 100g of ammonium bicarbonate\100g of sucrose (200g of nutrients are added to 1L of medicament, the weight ratio of ammonium bicarbonate and sucrose is 1:1), dissolve in 1000 liters of tap water, and the ratio of each medicament Treat and spray 30 trees, spray with a garden spray device, the amount of spray can be completely sprayed, and it is not suitable to re-spray. The test was carried out in Nanjing City, in early spring, in the afternoon, the weather was fine and the wind force was 4. P...

[0035] The test design takes 490 grams of glyphosate potassium salt, 49 grams of ethephon, and about 100 grams of additives (40 grams of sodium α-alkenyl sulfonate, 55 grams of alkyl glycosides, 5 grams of tea saponin and a small amount of defoamer ), prepared with water into 1 liter of liquid medicine, without adding, adding urea 25g\sucrose 25g, urea 75g\sucrose 75g, urea 125g\sucrose 125g / liter, the treatment concentration was 0.06% (0.6g plant growth Conditioning agent, the same below), every kind of medicament proportioning treatment sprays 30 trees, sprays with garden spraying device, and the spray quantity is sprayed to get final product completely, should not be heavy sprayed. The test was carried out in Nanjing City, in early spring and at night, the weather was fine and the wind force was 4. The sycamore is just in the budding stage. Before processing, count the number of actual result balls in each tree for comparison.
