Problems solved by technology

[0003] One of the main reasons for postharvest disease of mango fruit is that the fruit has been latently infected by fungal microorganisms in the field before harvest. Therefore, it is not enough to focus on postharvest treatment in fruit preservation research, and various complicated postharvest treatments will increase. Labor costs and postharvest losses

Embodiment 1

[0014] A pre-harvest treatment method for disease-resistant and fresh-keeping of mango fruit, the specific steps are as follows:

[0015] Step 1. One month before the mango fruit is harvested, evenly spray the mixed disease-resistant preservative on the surface of the mango fruit. The mixed disease-resistant preservative includes 0.5g / L of γ-aminobutyric acid and 50mg / L of β- Aminobutyric acid, 0.5g / L potassium cinnamate, 50mg / L polyoxin and 0.1% emulsifier 4209-A, until dripping, and then put the fruit in a paper fruit bag;

[0016] Step 2: Harvest mangoes with fruit bags when the maturity is 70-80%, investigate the diseased fruit rate at this time, and then select good fruits without disease spots and mechanical injuries and put them in cardboard boxes. The weight of each box is 5kg. A layer of wrapping paper is placed on the surface of the mangoes and mangoes, and finally the mangoes are stored at 23°C.

[0017] In Example 1, the diseased fruit rate was 8.8% when the mango...

Embodiment 2

[0019] A pre-harvest treatment method for disease-resistant and fresh-keeping of mango fruit, the specific steps are as follows:

[0020] Step 1. One month before the mango fruit is harvested, use a mixed disease-resistant preservative (including) to evenly spray on the surface of the mango fruit. The mixed disease-resistant preservative includes 0.5g / L γ-aminobutyric acid, 100mg / L β-aminobutyric acid, 0.5g / L potassium cinnamate, 50mg / L polyoxin and 0.1% emulsifier 4209-A until dripping, and then put the fruit in a paper fruit bag.

[0021] Step 2: Harvest mangoes with fruit bags when the maturity is 70-80%, investigate the diseased fruit rate at this time, and then select good fruits without disease spots and mechanical injuries and put them in cardboard boxes. The weight of each box is 5kg. A layer of wrapping paper is placed on the surface of the mangoes and mangoes, and finally the mangoes are stored at room temperature at 25°C.

[0022] In Example 2, the diseased fruit r...

Embodiment 3

[0024] A pre-harvest treatment method for disease-resistant and fresh-keeping of mango fruit, the specific steps are as follows:

[0025] Step 1. One month before the mango fruit is harvested, evenly spray the mixed disease-resistant preservative on the surface of the mango fruit. The mixed disease-resistant preservative includes 1.0g / L of γ-aminobutyric acid and 50mg / L of β- Aminobutyric acid, 1.0g / L potassium cinnamate, 100mg / L polyoxin and 0.2% emulsifier 4209-A, until dripping, and then put the fruit in a paper fruit bag;

[0026] Step 2: Harvest mangoes with fruit bags when the maturity is 70-80%, investigate the diseased fruit rate at this time, and then select good fruits without disease spots and mechanical injuries and put them in cardboard boxes. The weight of each box is 5kg. A layer of wrapping paper is placed on the surface of the mangoes and mangoes, and finally the mangoes are stored at room temperature at 22°C.

Abstract

The invention discloses a pre-harvest treatment method for disease resistance and fresh keeping of mango fruits, which comprises the following steps: step 1: uniformly spraying a mixed disease-resistant fresh-keeping agent on the surfaces of the mango fruits at 1 to 2 months before harvest of the mango fruits, and sheathing the fruits with paper bags; and step 2: after the mongo fruits are harvested, packing with a carton, and storing at 22-28 DEG C. The mixed disease-resistant fresh-keeping agent used in the invention has the characteristics of safety and environmental friendliness. The mango fruits subjected to pre-harvest treatment of the disease-resistant fresh-keeping agent have obviously decreased diseased fruit rate in harvesting, up to 28.7-57.2% compared to the control group, when the mango fruits are stored at 22-28 DEG C for 10 days, the damage by disease is obviously reduced, the disease index of the mango fruits is reduced by 43.0-57.3% compared to the control group, and the commercial fruit ratio is increased to 79.9-109.8% compared to the control group. The pre-harvest treatment method effectively reduces the growth period of the mango fruits and the disease occurrence during room temperature storage period, and is environment-friendly and safe, convenient to operate, and easy to promote and apply.

Description

technical field [0001] The invention relates to a fresh-keeping method, in particular to a pre-harvest treatment method for disease-resistant and fresh-keeping of mango fruits. Background technique [0002] Mango has the characteristics of bright and beautiful skin and flesh color, good flavor and strong aroma. It is very popular among domestic and foreign consumers and is known as the "king of tropical fruits". China is one of the main producing countries of mango, mainly distributed in Hainan, Guangdong, Guangxi, Sichuan, Yunnan and Taiwan provinces. The mango planting area is rapidly expanding, with high commodity value and remarkable economic benefits. It has become the main pillar industry for local farmers to increase their income. Mangoes are susceptible to latent infection by pathogenic microorganisms during field growth, and their metabolism is vigorous after harvesting. As a result, mangoes are prone to disease and rot during postharvest storage and transportation...
