Disinfection treatment method and disinfectant solution for improving cultivation quality of oriental lily bulbs

Abstract

The invention discloses a disinfection treatment method and a disinfection liquid for improving the cultivation quality of oriental lily bulbs. The method comprises the steps of bulb disinfection, grading treatment, bulb cartonning matrix disinfection treatment, cartonning treatment, bulb refrigeration, bulb unfreezing and low temperature pre-rooting treatment. The invention also provides the disinfection liquid. The disinfection treatment method and the disinfection liquid for improving the cultivation quality of oriental lily bulbs realize long term preservation and high-activity growth ability maintenance of fresh cut flower lily bulbs, and solve the problems of root contraction and bulb decaying caused by long-term freezing storage of the bulbs through combining a disinfection method with a refrigeration method.

Description

Technical field: [0001] The invention belongs to a method for cultivating oriental lily bulbs, in particular to a disinfection treatment method and a disinfectant solution for improving the cultivation quality of oriental lily bulbs. Background technique: [0002] Lily is a perennial herbaceous plant of the genus Lilium in the family Liliaceae. It has become one of the world's largest fresh cut flowers for its large flowers, bright colors, and rich flower shapes and colors. my country is the natural distribution center of Lilium plants. There are about 94 species of Lilium plants found in the world, more than half of which originated in my country. At present, the domestically cultivated lilies mainly include Oriental lily, OT hybrid lily and Asiatic lily. Due to the late start of lily breeding work in my country, the production of lily commercial bulbs is small, lily bulbs are susceptible to virus disease infection and degradation, and bulb refrigeration technology is backw...

Problems solved by technology

[0005] The quality of lily bulbs after frozen storage directly affects the emergence rate, growth status and cut flower quality after planting. The most prominent problems after frozen storage of lily bulbs are prone to bulb chassis rot, chassis root wilting or shrinking, and bulb penicillium Hazards, etc. With the prolongation of refrigeration time, the situation becomes more serious, and even completely loses the commodity value of the bulbs. In serious cases, the rot rate of lily bulbs is nearly 100%.

The main reason is that the roots of the bulbs are easily injured during harvesting and cleaning operations, and the wounds on the roots of the bulbs have not been effectively healed before the bulbs are frozen, and the roots of the bulbs have high water content, and the risk of root tissue damage during the freezing process is significantly increased , leading to the infection of weak parasitic fungi, causing root necrosis, and then the fungus invades the bulb chassis from the root of the necrotic chassis, causing the bulbs to rot. Infection of parasitic fungi, so it is imminent to strengthen the research on the cold storage and disinfection treatment technology of lily bulbs. There is no detailed report on a disinfection treatment method to improve the quality of frozen storage of oriental lily bulbs in China.
