Abstract

The present invention discloses a method for inhibiting postharvest blossom of daylily, the specific steps of the method are as follows: (1) picking daylily: picking daylily flower buds five days before flowering and choosing buds with uniform size and without damage, disease and pest ; (2) preparation of packaging materials: adding 0.14 gram of 1-MCP and 1.34 grams of allicin powder into per hundred grams of powder sealed in the antistaling agent paper wrap, and sealing 10 grams of powder into every package; (3) refreshing processing: adding daylily flower buds picked in step (1) and a bag of antistaling agent prepared in step (2) into a 0. 05mm thick polyethylene fresh bag, and sealing the bag with a heat sealing machine. The present invention delays the flowering of daylily at a temperature of 20 to 25 DEG C for more than 12 days, which is extended 5 to 8 times compared to the control, and also can well suppresses the respiration of daylily and postharvest quality decline. The present method has no chemical residue, has a good refreshing effect, meets people's consumption concept of pursuing natural and green food, and is suitable for long distance transportation of daylily and prolongs the shelf life of daylily.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a method for inhibiting flowering of day lilies after harvesting. Background technique [0002] Daylily-flower (Hemerocallis citrine Baroni, Daylily-flower), also known as daylily, has a planting history of thousands of years in my country and is a characteristic vegetable with high economic value. Its nutritional content is richer than that of ordinary vegetables.
