Lilium oriental hybrids cutflower second-generation seedball rejuvenation utilizing method

Abstract

The invention relates to a lilium oriental hybrids cutflower second-generation seedball rejuvenation utilizing method which mainly comprises the following steps of: cultivating seedballs after cutflowers are picked, harvesting the seedballs, sorting out, cleaning and sterilizing; gradually cooling the sterilized seedballs to 2-4 DEG C in a refrigeration house within 5-10 days, wherein the air humidity is 50-75 percent, and the concentration of CO2 is lower than 1,000ppm; carrying out cold treatment for 5-8 weeks to break dormancy, and then directly seeding or further cooling to -1.5 DEG C for freezing and preserving for 65-100 days; and then planting. The invention has the advantages that low-temperature treatment conforms to the physiological rules of the lilium oriental hybrids and can break the dormancy, shorten the childbearing period, promote the flower bud differentiation and ensure that plants have nutrition and vigorous growth, the leaf surface areas are increased, flowers are large, the cutflower weight is increased, and the cutflower quality and the commodity rate are improved; the refrigeration of the seedballs is safe, and the blooming time of the lilium oriental hybrids can be manually regulated and controlled so as to meet the requirement for supplying to the market at the annual time of the flowers; and the production cost is greatly reduced, and the cutflower planting economic benefit is improved.

Problems solved by technology

At present, there are 2 kinds of treatment methods for the low-temperature treatment of the second crop bulbs. One is cold storage treatment. As disclosed in the Chinese patent document CN101189945A, a method for utilizing oriental second-generation bulbs is adopted, but it is general. The second is the natural low temperature treatment in the field. Some growers protect the bulbs overwintering on the spot after harvesting the cut flowers, and do not dig them. This method is adopted. Due to the complex process of storage and treatment, the biomass of roots and bulbs is not lost. The disadvantage is that the quality of cut flowers is not high, and due to the restrictions of geographical environment and seasons, it cannot be carried out all year round, and it is difficult to meet the needs of the annual supply market of lily fresh cut flowers.
