Problems solved by technology

However, dragon fruit is sensitive to low temperature during refrigeration and fresh-keeping. The cost of low-temperature storage and preservation is high, and chilling injury will easily occur. Chilling injury can occur when the storage temperature is below 4°C. Chilling injury not only affects the appearance of the fruit, but also reduces the quality of the fruit. After the fruit is moved from low temperature to normal temperature, due to the decline in its resistance and disease resistance, as well as its own physiological disorders, it rots faster than the fruit that has been kept at normal temperature; Smooth and flat, it is not easy to form a complete film layer, and the fresh-keeping effect is not very good

Embodiment 1

[0020] Embodiment 1 A kind of method 1 that reduces dragon fruit postharvest rot loss

[0021] (1) After the dragon fruit fades, when the young fruit is 3-4cm in length, spray the disease resistance inducer A on the young fruit (ratio of each component: N-acetyl-5-methoxytryptamine 50mg / L , methyl jasmonate and its derivatives 150mg / L, brassinolide and its derivatives 400mg / L, chitosan 0.5g / L, nonylphenol polyoxyethylene ether 50g / L, purified water to make up 1L), Immediately cover with non-woven bag until harvest.

[0022] (2) After bagging, every 10 days, spray the disease resistance inducer B on the fruit-setting stems (the distribution ratio of each component is: N-acetyl-5-methoxytryptamine 50mg / L, salicylic acid 25mg / L, nonylphenol polyoxyethylene ether 50g / L, polyvinyl alcohol 1g / L, purified water to make up 1L).

[0023] (3) Three days before harvest, spray the disease resistance inducer C again (the proportion of each component is: β-aminobutyric acid 50mg / L, benzot...

Abstract

The invention discloses a method for reducing postharvest rot loss of dragon fruits. The method specifically comprises four steps of periodically spraying a disease-resistant inductive agent A after blossoms fall, spraying a disease-resistant inductive agent B to fruitlets every 10 days after bagging is conducted, spraying a disease-resistant inductive agent C 3 days before harvest, and conducting antisepsis and cooling treatment after harvest. According to the method for reducing the postharvest rot loss of the dragon fruits, the postharvest rot loss of the dragon fruits can be effectively reduced, and the storage time is prolonged; after the method is continuously applied, the probability that the dragon fruits carry diseases in the later period can be greatly reduced, and compared with a traditional cold storage and preservation technology, the method is safer and more effective.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable preservation, in particular to a method for reducing post-harvest rot loss of dragon fruit. Background technique [0002] Dragon fruit (Latin scientific name: Hylocereus undatus ) Also known as red dragon fruit, fairy fruit, lover fruit, etc., it belongs to the cactus family ( Cactaceae ) Trigonal genus ( Hylocereus ) and Shih Tzu ( Selenicereus ), which is unique in shape, bright in color and rich in nutrition, is a new tropical health-care fruit integrating fruits, flowers and vegetables, and is widely loved by consumers. Dragon fruit is mainly planted in southern my country. It is rich in nutrition and has unique functions. It is a low-energy fruit rich in water-soluble dietary fiber, which has the effects of losing weight, lowering cholesterol, preventing constipation, and colorectal cancer. Dragon fruit contains plant-based albumin, which is rarely found in general vegetab...
