Problems solved by technology

[0004] However, during postharvest storage and transportation of dragon fruit, due to fruit senescence and decreased resistance, the pathogenic bacteria infected before and after harvest change from a latent state to a pathogenic state, causing fruit disease and rot; low temperature storage reduces the physiological metabolic rate, but it is prone to Chilling damage, the condensed water on the surface of the fruit after leaving the warehouse accelerates the rot of the fruit, resulting in post-harvest loss
[0005] The inventor applied for the patent "Method of Prolonging the Low-temperature Storage Time of Zihonglong Dragon Fruit" after harvesting, soaking in 75-85mg / L chlorine dioxide solution for 5 minutes to sterilize, draining and soaking in 8-12mmol / L oxalic acid for 10 minutes to induce cold resistance , It is found that it takes a long time to apply in production, and the demand for labor and space is large, which is not conducive to large-scale treatment, and chlorine dioxide and oxalic acid are corrosive to grading equipment

Abstract

The invention discloses a disease-preventing and fresh-keeping method for prolonging storage period of dragon fruits. According to the method, through pre-harvest bactericide and resistance inductiontreatment, callus, pretreatment, pre-storage, packaging and other treatment, the dragon fruits are stored in a refrigeration house and then exposed out of the refrigeration house in an anti-condensation mode, the method can significantly reduce rate of fruits with diseases such as canker, reduce rate of purple red dragon fruits with diseases during harvest by 50%, significantly delay onset time ofthe dragon fruits, effectively prolongs storage time and room temperature shelf life of the dragon fruit, and the report loss rate of the dragon fruit is also lower than 2% within 48 hours of expresslogistics after delivery. The entire method requires less time, is free of corrosion and capable of reducing labor force.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a disease prevention and preservation method for prolonging the storage period of pitaya. Background technique [0002] Dragon fruit (scientific name: Hylocereus undatus 'Foo-Lon') is a cultivar of the genus Liangtianchi in the cactus family. It climbs on succulent shrubs and has aerial roots. Many branches, extending, leaf edges often wing-shaped, edge wavy or crenate, dark green to light blue-green, bony; flowers funnel-shaped, open at night; scales ovate-lanceolate to lanceolate, calyx-shaped Tepals yellow-green, linear to linear-lanceolate, petal-like perianths white, oblong-oblanceolate, filaments yellow-white, styles yellow-white, berries red, long spherical, navel small, flesh white, red . Seed obovate, black, hilum small. Flowering and fruiting from July to December. [0003] Dragon fruit not only tastes sweet, but also has high nutritional value. It combines th...
