Problems solved by technology

Due to its own structural characteristics, there are pompoms formed by white pistils on the seeds, which drift with the wind after blooming. If artificially planted dandelions encounter strong winds during seed harvesting, the seed yield will decrease, which will bring economic benefits. loss

Embodiment Construction

[0021] 1. Seed acquisition

[0022] The mountaintop area of ​​Guanshan Ranch in Longxian County, Baoji City, Shaanxi Province, has been in the natural conditions of wind force level 5 or above for a long time. During the maturity stage of dandelion seeds, the inventor of the applicant found wild Dandelion plant, and obtained the seed of this wild dandelion, and the outward appearance characteristic of this wild dandelion is as follows:

[0023] 1) Leaves oblanceolate, 10-30 cm long, apex pointed or blunt, irregularly pinnately lobed to deeply lobed, apex lobe diamond-shaped triangular or triangular, 4-5 lobes on each side, slightly backward, lobes Triangular or long triangular, entire or margin sparsely toothed, sparsely pubescent or glabrous on both surfaces ( figure 1 ).

[0024] 2) Scapes are numerous, 10-20 cm high, beyond the leaves during flowering, slightly sparsely pubescent, densely covered with white spider-like hairs near the top.

[0025] 3) The involucre is 13-...

Abstract

The invention discloses a non-dropping dandelion strain breeding method. The method includes selecting wild northeast dandelion seeds matured under natural conditions with wind power of more than 5 levels in Guanshan areas; sowing, weeding, interleaving, fixing seedlings and preforming fertilizer and water management in fields according to a conventional method; after the wild northeast dandelionseeds mature, screening the wild northeast dandelion plants for the first time, wherein the specific method includes shaking the wild northeast dandelion plants left and right two to three times by ahand, with the shaking range being 15 degrees to the left and 15 degrees to the right; screening the wild northeast dandelion plants after the first screening in the second time by using a hairdryer to simulate the natural wind speed of level 5; and harvesting the seeds which do not fall on the wild northeast dandelion plants after the second screening to obtain the non-falling dandelion strain. The non-falling dandelion strain can improve the non-falling ability of dandelions and obviously reduce the difficulty of harvesting seeds planted artificially, and is a new dandelion strain with strong stress resistance.

Description

technical field [0001] The invention belongs to the technical field of artificial breeding of plant strains, and in particular relates to a breeding method of non-shattering dandelion strains. Background technique [0002] Dandelion is a perennial herbaceous plant, because the plant contains various healthy nutrients such as dandelion alcohol, dandelion, choline, organic acid, inulin, etc., it is a plant with both medicine and food. The main species of dandelion in our country are: Northeast dandelion, multi-lobed dandelion, white edge dandelion, Chinese dandelion, variegated dandelion, cangye dandelion and so on. [0003] Dandelion is a short-day plant. Under high temperature and short-day conditions, it is conducive to bolting and flowering, and is more shade-tolerant, but good light conditions are conducive to the growth of stems and leaves. It has strong adaptability and does not choose soil for growth, but it grows better in sunny, fertile, and moist sandy loam soil; i...
