Lilium brownii var.viridulum filial generation bulb expanding, developing and rooting method

Abstract

The invention provides a lilium brownii var.viridulum filial generation bulb expanding, developing and rooting method which comprises the following steps: 1, saving lilium brownii var.viridulum filial generation embryonic plants to make seedlings; 2, performing clumpy bud multiplication and quickly multiplying the seedling amount to make clump seedling; 3, performing bulblet induction and cultivating differentiated bulbs; 4, expanding and rooting bulblet, cultivating larger bulbs, rooting the larger bulbs and using the larger bulbs as a breeding original material for production to be directly transplanted into fields to be planted. By means of optimizing influence factors of quick expansion and rooting cultivation of hybrid lily bulbs, technical support is provided for large-scale production of lilium brownii var.viridulum filial generation test-tube plantlets; furthermore, technical assurance is provided for large-scale production of edible lilium brownii var.viridulum filial generation test-tube plantlets, and requirements of market for edible lily new hybrid varieties are met; thus, lilium brownii var.viridulum planting cost is reduced.

Description

[0001] Technical field: [0002] The invention relates to a lily cultivation method in the field of agricultural plant cultivation, in particular to a method for utilizing the bulb expansion and rooting of the hybrid progeny of the lily longya. [0003] Background technique: [0004] Lily is a perennial herbaceous bulb plant of the genus Lilium (scientific name: Lilium) of the Liliaceae family. Longya lily is one of the three main edible lily varieties in my country. It has a long-standing reputation. It is a famous and excellent variety among edible, medicinal and ornamental lilies, and it is also one of the varieties with the best nutritional value. Its bulbs are spherical, generally 4 to 6 cm in diameter, and the scales are lanceolate, white, yellowish white or slightly pink when exposed to the sun. High starch content, rich nutrition, light taste but not bitter, the height of the stem above the ground is about 90-120 cm, and the leaves are scattered and oblanceolate. The ...

Problems solved by technology

At present, there are few studies on the rapid expansion and optimization of rooting culture of lily lily bulbs

At the same time, in recent years, there have been many domestic reports on the methods of constructing lily hybrid progeny clone populations, but most of them focus on the research on cut lily, and there are few studies on edible lily.

There is no relevant report on the method of rapid expansion and rooting of the bulbs of the hybrid progenies of Longya Lily x Lanzhou Lily

[0006] On the other hand, the cultivation cycle of edible lily hybrid offspring bulbs is relatively long, and it takes at least 6-7 years to breed a variety. Such a long breeding cycle seriously restricts the scale and industrialization of the edible lily breeding industry. Market Demand for New Varieties of Self-cultivating Lily
