Abstract

The invention discloses a disease preventing and freshness retaining method of mango-fruit preharvest and postharvest combined processing. The method includes the steps: (1), within 1 month before mango-fruit harvesting, a mixed disease-resistant pesticide is uniformly sprayed to the surfaces of mango fruits; (2), the mango fruits obtained after preharvest processing are harvested and precooled; (3), the precooled mango fruits are placed into a plastic box, a citronella essential oil, a tea tree essential oil, a lemon essential oil and a macadamia ternifolia essential oil are added into a culture dish at the bottom of the box so that the volatile matter concentration of each essential oil can reach 250-500 [mu]l / L, sealing is conducted, and room-temperature fumigation is carried out for 8-16 hours; (4), fumigated mango fruits are taken out and then placed into a paper fruit box with a spontaneous modified atmosphere bag as a lining, and after a 1-MCP slow-release agent is added, an opening of the modified atmosphere bag is sealed; and (5), the mango fruits are stored in a room-temperature warehouse. After the mango fruits processed through the method are stored in the room-temperature warehouse for 8 days, diseases are significantly alleviated, the disease index of the mango fruits is 20.0-31.7, and prevention and treatment effects reach 54.7-71.4%.

Description

Technical field [0001] The invention relates to a mango fresh-keeping treatment method, in particular to a disease-preventing and fresh-keeping method combining pre-harvest and post-harvest treatments of mango fruits. Background technique [0002] Mango (Mangifera indica L.) has gorgeous appearance, tender meat, rich aroma, and unique flavor. It is popular with consumers at home and abroad. It is called the "King of Tropical Fruits". It is a province in my country such as Hainan, Guangxi, Sichuan and Yunnan. An important pillar industry of district agriculture. In recent years, the mango industry has achieved rapid development, with more and more varieties, increasing output, and increasing scale production, but it is also facing challenges brought by various problems. First, the occurrence of diseases and insect pests during the planting and growth of mangoes is increasing, and the difficulty of prevention and control is also increasing. In particular, the pathogenic bacteria th...
