Embodiment 1

[0023] Put the 7-8 mature mango fruits in a low-temperature storage at 15°C for 12 hours before harvesting, then wash them with tap water, and use a post-harvest disease-resistant preservative (containing 20mg / L salicylic acid, 50mg / Lβ-aminobutyric acid, 100mg / L 3-amino-1,2,4-triazole, 20g / L potassium cinnamate and 0.1% emulsifier AEO-5) evenly sprayed on the surface of mango fruit, after drying The fruit is packed into cardboard boxes, each box of fruit weighs 5kg, and a layer of wrapping paper is placed on the bottom and the surface, and finally the mango fruit is stored at room temperature (22-25°C). After storage for 10 days, the mango disease index was 25, which was 27.5 lower than that of the control, and the reduction reached 52.4%. The commercial fruit rate was 70%, which was 40% higher than the control, and the improvement reached 133%. The antiseptic and fresh-keeping treatment method can significantly improve the disease-resistant and fresh-keeping effect of the ma...

Embodiment 2

[0025] Put the 7-8 mature mango fruits in a low-temperature storage at 15°C for 12 hours before harvesting, then wash them with tap water, and use a post-harvest disease-resistant preservative (containing 20mg / L salicylic acid, 50mg / Lβ-aminobutyric acid, 0.2g / L 3-amino-1,2,4-triazole, 10g / L potassium cinnamate and 0.1% emulsifier AEO-5) evenly sprayed on the surface of mango fruit, and dried Finally, the fruit is packed into cardboard boxes, each box of fruit weighs 5kg, and one layer of wrapping paper is placed on the bottom and the surface, and finally the mango fruit is stored at room temperature (22-25°C). After 10 days of storage, the mango disease index was 35, which was 17.5 lower than that of the control, and the reduction reached 33.3%. The commercial fruit rate was 60%, which was 30% higher than the control, and the improvement reached 100%. The antiseptic and fresh-keeping treatment method can significantly improve the disease-resistant and fresh-keeping effect of ...

Embodiment 3

[0027]Put the 7-8 mature mango fruits in a low-temperature storage at 15°C for 12 hours before harvesting, then wash them with tap water, and use a post-harvest disease-resistant preservative (containing 20mg / L salicylic acid, 50mg / Lβ-aminobutyric acid, 0.2g / L 3-amino-1,2,4-triazole, 20g / L potassium cinnamate and 0.1% emulsifier AEO-5) evenly sprayed on the surface of mango fruit, and dried Finally, the fruit is packed into cardboard boxes, each box of fruit weighs 5kg, and one layer of wrapping paper is placed on the bottom and the surface, and finally the mango fruit is stored at normal temperature (22-25°C). After 10 days of storage, the mango disease index was 40, which was 12.5 lower than that of the control, and the rate of reduction reached 23.8%. The antiseptic and fresh-keeping treatment method can significantly improve the disease-resistant and fresh-keeping effect of the mango fruit.

Abstract

The invention discloses a postharvest disease-resistant preservative for mango fruits. The postharvest disease-resistant preservative comprises the following components: salicylic acid with concentration of 20-40mg / L, beta-aminobutyric acid with the concentration of 50-100mg / L, 3-amino-1, 2, 4-triazole with the concentration of 0.1-0.2g / L, potassium cinnamate with the concentration of 10-20g / L and an emulsifier AEO-5 with the concentration in volume percentage of 0.1-0.2%. The invention further provides a postharvest disease-resistant preservation method for mango fruits. The postharvest disease-resistant preservation method comprises the following steps: harvesting the mango fruits when the ripening degree is 70%-80%, then pre-cooling and washing the mango fruits, further uniformly spraying the preservative stored at normal temperature on the surfaces of the mango fruits, air-drying, then packaging and storing at normal temperature. By adopting the postharvest disease-resistant preservation method provided by the invention, the plant diseases of the mango fruits during the storage period can be effectively reduced, the shelf life of mangoes is prolonged, the operation is convenient and fast, and the postharvest disease-resistant preservation method is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of fruit preservation, and in particular relates to a postharvest disease-resistant preservation method for mango fruits, and also relates to a postharvest disease-resistant preservation agent for mango fruits. Background technique [0002] Mango (Mangifera indica L.) has the characteristics of bright and beautiful skin and flesh color, tender flesh, 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 mango producing countries, and mango production is mainly distributed in Hainan, Guangdong, Guangxi, Sichuan, Yunnan, Fujian, Taiwan and other provinces and regions. 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. However, since mango is a typical tropical fruit, it i...
