Embodiment 1

[0035] The commercial bulbs of the Chinese narcissus 'Jinzhan Yintai' are used as culture materials. 60 Co gamma ray radiation dwarfing technology optimization method is to described narcissus bulb bulb hydroponic dwarfing method, comprises bulb bulb screening, 60 Co gamma radiation, pretreatment, PP 333 Steps such as soaking and hydroponic environmental factor control are as follows:

[0036] 1. Purchasing 75 commercial bulbs of the Chinese narcissus 'Jalendula Yintai' harvested in the same year as the second-grade three-year-old in the industry.

[0037] 2. Carry out the above-mentioned narcissus bulb 60 Coγ-ray radiation treatment, the absorbed dose is set to 5Gy.

[0038] 3. Peel off the brown scales of narcissus bulbs after irradiation, dig out the dead roots, and spread them in a cool and dry place for 1-2 days.

[0039] 4. Soak the pretreated narcissus bulbs in 1.5 mg / L paclobutrazol solution for 4 days.

[0040] 5. During the hydroponic cultivation process of narc...

Embodiment 2

[0043] In the present embodiment, step 2 is, carry out to the narcissus bulb 60 Coγ-ray radiation treatment, the absorbed dose is set to 8Gy. Step 4 is soaking the pretreated narcissus bulbs in 2.5 mg / L paclobutrazol solution for 4 days. Other steps are with embodiment 1.

[0044] In this embodiment, the average leaf height is 22.15cm, compared with Comparative Example 1, the leaf height is shortened by 48.70%, and the initial flowering stage is delayed by 19 days.

Embodiment 3

[0046] In the present embodiment, step 2 is, carry out to the narcissus bulb 60 Coγ-ray radiation treatment, the absorbed dose is set to 11Gy. Step 4 is soaking the pretreated narcissus bulbs in 2.5 mg / L paclobutrazol solution for 4 days. Other steps are with embodiment 1.

[0047] In this embodiment, the average leaf height is 16.70 cm, compared with Comparative Example 1, the leaf height is shortened by 61.32%, and the initial flowering stage is delayed by 22 days.

Abstract

The invention relates to a 60Co gamma-ray radiation dwarfing method for narcissus tazetta chinensis 'Jinzhanyintai'. The method includes steps: (1) selecting a narcissus tazetta chinensis 'Jinzhanyintai' variety in appropriate bulb diameter; (2) subjecting an obtained narcissus tazetta bulb to 60Co gamma-ray radiation; (3) pretreating the narcissus tazetta bulb; (4) soaking the narcissus tazetta bulb in paclobutrazol; (5) hydroponically culturing the narcissus tazetta bulb. In key steps of the method, a 60Co gamma-ray radiation dwarfing technique is adopted and supplemented by paclobutrazol soaking treatment; by effective control of temperature, humidity, illumination and moisture in a hydroponic culture process, the problem of excessive growth in a hydroponic culture process of narcissustazetta chinensis is solved, a leaf height range of narcissus tazetta is 15.96cm-32.46cm, the leaf height is reduced by 24.81%-63.03%, the early blooming period is delayed by 17-27d, the ornamental value of narcissus tazetta is greatly increased, and an application range of narcissus tazetta is greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a Chinese narcissus 'Calendula Yintai'. 60 Co gamma ray radiation dwarfing technology optimization method. Background technique [0002] Chinese narcissus (Narcissus tazetta L.var. Chinensis Roem) belongs to Amaryllidaceae, genus Narcissus, a perennial monocot herb, named by Swedish botanist Linnaeus. In the classification system given by the Royal Horticultural Society, the authority of Chinese Narcissus taxonomy, it is classified as a main variety of French Narcissus in the Jonquilla and Apodanthus Daffodil cultivars. The species are mainly distributed in coastal warm and humid regions such as China, Japan and Korea. At present, Chinese narcissus are mostly distributed in the coastal islands of Fujian, Zhejiang and Shanghai in my country. There are three main cultivars: 'Calendula Yintai' (single-petal Chinese narcissus), 'Yu Linglong' (double-petal Chin...
