Embodiment 1

[0032] Beginning in September 2016, the 'Zaohong' navel orange variety was planted in a citrus orchard in Jiuwanxi, Zigui County, Yichang City, Hubei Province for 8 years. 'A navel orange tree with consistent growth was used as a test.

[0033] Select 28 'Zaohong' navel orange citrus trees that grow robustly, have the same crown size and growth potential, and are free from diseases and insect pests. They are divided into 7 treatments and listed according to different treatments. Combined with the incidence of early red navel orange oil spot disease, the Drugs are screened, and there are seven treatments in total, which are:

[0034] 1. ABA200: abscisic acid with a concentration of 200mg / L

[0035] 2. PTT+ABA: 1g / L glucose and 60mg / L abscisic acid

[0036] 3. ABA60: abscisic acid with a concentration of 60mg / L

[0037] 4. YXL+ABA+PTT: Ethephon (40% quality commercially available) with a concentration of 150mg / L+10mg / L abscisic acid+1g / L glucose

[0038] 5.PTT+BR: 1g / L gluco...

Embodiment 2

[0043]Beginning in September 2015, the early red navel orange variety was planted in a citrus orchard in Jiuwanxi, Zigui County, Yichang City, Hubei Province. A more consistent tree body was used as a test.

[0044] Select 44 early red navel orange citrus fruit trees that grow robustly, have the same crown size and growth potential, and are free of diseases and insect pests. They are divided into 11 treatments and listed according to different treatments. Combined with the incidence of early red navel orange oil spot disease, the pesticides are tested. Screening, a total of 11 treatments are set up, which are:

[0045] 1. CK (control): clean water

[0046] 2. SYS+XSG+KJT: 3.06g / L salicylic acid+0.1g / L calcium nitrate+0.1g / L chitosan

[0047] 3. XSG+GA: 10mmol / L calcium nitrate + 20mg / L gibberellin

[0048] 4. 5: 1mg / L of 5-chloro-3methyl-4-nitro-1h-pyrazole

[0049] 5. 5+BR: 1mg / L 5-chloro-3methyl-4-nitro-1h-pyrazole+0.1mg / L brassinosteroid

[0050] 6.TRIS+GA: TRIS-HCL+30...

Abstract

The invention provides a composition for prevention and treatment of citrus oleocellosis. The composition comprises 50-300mg / L ethephon, 5-60mg / L abscisic acid and 1-5g / L low-molecular monosaccharides. By a combination formulation of ethephon, ABA (abscisic acid) and low-molecular monosaccharides, evident effects in decrease of an attack rate of citrus oleocellosis are achieved. Combined application of the agents to prevention and treatment of citrus oleocellosis is realized for the first time, post-harvest fresh keeping performance of citrus is effectively improved, and a promising application prospect of the composition in post-harvest of citrus is verified. Therefore, a method for reducing citrus oleocellosis by a pharmaceutical composition formulation of ethephon, abscisic acid and low-molecular monosaccharides is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of citrus postharvest, and in particular relates to a preharvest orchard management method for reducing the occurrence of oil spot disease of citrus fruits. Background technique [0002] Citrus is the largest fruit in southern my country. With the improvement of national consumption level, consumers have higher and higher requirements for the internal quality and appearance quality of fruits. In production, many fruits with insufficient pericarp color change or high chlorophyll content during the harvest period are prone to oil spot disease during postharvest commercialization or storage and transportation, which seriously affects the appearance and quality of fruits. The losses are increasing year by year. The symptoms of citrus oil spot disease are mainly irregular light yellow lesions on the peel, which are yellowish white at first, and then yellow or brown. Oil cells gradually shrink into dry scars, wh...
