Abstract

The invention discloses a dwarfing method of Lilium regale plants, which comprises the following steps: s1, selecting Lilium regale seedballs with consistent sizes, soaking the seeds for 30min by using 50% carbendazim in 500 times, taking out and airing the seeds and planting the seeds; s2, after Lilium regale sprouts and when the Lilium regale grows to 14-16 cm, respectively treating the Lilium regale by using a plant growth regulator; the specific implementation method comprises the following steps: respectively spraying 3200mg/L of CCC, 800mg/L of PP333 and 2000mg/L of B9 to Lilium regale plants for one time; or carrying out two times of spraying on the Lilium regale plants by using 800mg/L CCC, 800mg/L PP333 and 8000mg/L B9 respectively, wherein the interval between the two times of spraying is 15 days. The dwarfing of the Lilium regale plants is realized by using a plant growth regulator, ultraviolet lamp radiation treatment and other methods, the ornamental value of the Lilium regale plants as pot flowers is improved, and the commercial development of the Lilium regale pot flowers is facilitated.

Description

lilium regale plant dwarfing method

Technical Field

The invention belongs to the technical field of plant cultivation, and particularly relates to a method for dwarfing a Lilium regale plant.

background

Lilium regale Wilson, also known as king lily and Lilium crispum, is a plant of the genus Lilium of the family Liliaceae. Flowers 1 to several, fragrant when opened, trumpet-shaped, white, yellow throat. Mainly distributed in the upstream arid valley zone of the Minjiang river basin in Sichuan province in China. Has strong drought resistance, cold resistance, sun resistance, half-yin preference, high temperature resistance and salt and alkali resistance. Lilium regale, as a wild lily, was once introduced into europe by western people, is an important resource for saving the crisis of western commercial lilies. Lilium regale is not only an important ornamental plant, but also used as a cutting flower or bulbous garden. The bulb contains rich nutrients, can be used as a food material, can be eaten fresh and dry, has good nutrition and nourishing effects, can be used for medicine, and has the effects of nourishing the heart, soothing the nerves, moistening the lung and relieving cough.

The Lilium regale large-scale white yellow throat has rich fragrance and high ornamental value, is strong in nature and disease-resistant and drought-resistant, and is a precious wild germplasm resource. Although the Lilium regale has high ornamental value, the Lilium regale is only used for making fresh cut flowers and garden ornamental plants at present due to the plant height of about 1.5-2 m, and the commercial development value of the Lilium regale as a pot flower is severely limited. And no related research report about the dwarfing of Lilium regale plants is seen at present. Dwarfing of the Lilium regale plants is realized by using a plant growth retardant, ultraviolet lamp radiation treatment and other methods, the ornamental value of the Lilium regale plants as pot flowers is improved, the commercialization development of the Lilium regale pot flowers is facilitated, and the method has important significance for developing the wild germplasm resource of the Lilium regale.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a method for dwarfing Lilium regale plants, which realizes dwarfing of the Lilium regale plants by using a plant growth regulator, ultraviolet lamp radiation treatment and other methods, improves the ornamental value of the Lilium regale plants as pot flowers and is beneficial to the commercial development of the Lilium regale plants.

The purpose of the invention is realized by the following technical scheme: a Lilium regale plant dwarfing method comprises the following steps:

s1, selecting Lilium regale seedballs with consistent sizes, soaking the seeds for 30min by using 50% carbendazim in 500 times, taking out and airing the seeds and planting the seeds;

S2, after Lilium regale sprouts and when the Lilium regale grows to 14-16 cm, respectively treating the Lilium regale by using a plant growth regulator; the specific implementation method comprises the following steps: respectively spraying 3200mg/L of CCC (CCC: chlormequat chloride), 800mg/L of PP333(PP 333: paclobutrazol) and 2000mg/L of B9 (B9: butyrhydrazide) to the Lilium regale plants for one time;

Or carrying out two times of spraying on the Lilium regale plants by using 800mg/L CCC, 800mg/L PP333 and 8000mg/L B9 respectively, wherein the interval between the two times of spraying is 15 days.

Further, in the step S2, the Lilium regale plants are sprayed to the extent that the whole plants are wet and water drops do not drip.

The invention has the beneficial effects that: the dwarfing of the Lilium regale plants is realized by using a plant growth regulator, ultraviolet lamp radiation treatment and other methods, the ornamental value of the Lilium regale plants as pot flowers is improved, the commercialization development of the Lilium regale pot flowers is facilitated, and the method has important significance for developing the Lilium regale wild germplasm resource.

Detailed Description

The technical scheme of the invention is further explained by combining specific examples.

A Lilium regale plant dwarfing method comprises the following steps:

the dwarfing effect of the present invention was further verified by experiments as follows.

Plants were treated by spraying CCC, PP333, B9 at different concentrations as shown in Table 1, to the extent that the entire plant was wet sprayed and no water droplets dropped. After 15 days, half of each group was sprayed for the second time, and the spraying solution was the same as the first time.

TABLE 1 concentration gradient of CCC, PPP333, B9

CCC	0	100	200	400	800	1600	3200
								PP₃₃₃	0	25	50	100	200	400	800
B₉	0	250	500	1000	2000	4000	8000

As a result: in case of only one spraying: CCC (3200mg/L), PP333(800mg/L) and B9(2000mg/L) have good effects. The plant height growth reduction rates were 93.72%, 63.24% and 54.89%, respectively.

In case of two sprays: CCC (800mg/L), PP333(800mg/L) and B9(8000mg/L) have good effects. The plant height increase reduction rates were 91.14%, 59.71% and 51.23%, respectively.

overall, CCC dwarfing was best followed by PP333, and relatively worse B9.

The flower morphology did not change significantly.

It will be appreciated by those of ordinary skill in the art that the embodiments described herein are intended to assist the reader in understanding the principles of the invention and are to be construed as being without limitation to such specifically recited embodiments and examples. Those skilled in the art can make various other specific changes and combinations based on the teachings of the present invention without departing from the spirit of the invention, and these changes and combinations are within the scope of the invention.
