Problems solved by technology

At present, the breeding methods of evergreen are mainly divided into bulbs and sowing. Although it is relatively easy to survive, a mature bulb can be divided into less than 10 bulbs per year, and the reproductive efficiency is very low. The emergence rate of sowing and breeding is not high. Long, about 3 years, greatly affects production efficiency

Embodiment 1

[0015] Select a cue ball with a diameter of 22 centimeters and carry out cutting propagation.

[0016] 1. Preparation of culture medium: Take dry peat soil, perlite and vermiculite according to the ratio of 3:1:1 to form a culture medium, and then put it in an autoclave and sterilize it at 121°C for 40 minutes;

[0017] 2. Adjustment of the pH value of the culture medium: add an appropriate amount of water to the culture medium to make it moist, adjust the pH of the culture medium to 6.3, then pour the culture medium into the seedling tray for later use, and adjust the pH value of the culture medium with dilute phosphoric acid, Sodium hydroxide solution;

[0018] 3. Cutting and disinfection of the bulb of the mother plant: take the evergreen cue ball, clean it, remove the outer layer of dry scales, put the bulb up, and cut the cue ball longitudinally from top to bottom into 16 pieces, and ensure that each part has Bulb discs, and then soak the slices of these cut evergreen bu...

Embodiment 2

[0022] Select a cue ball with a diameter of 26 centimeters and carry out cutting propagation.

[0023] 1. Preparation of culture medium: Take dry peat soil, perlite and vermiculite according to 3:1:1 and mix into culture medium, then put it in an autoclave and sterilize at 121°C for 35 minutes;

[0024] 2. Adjustment of the pH value of the culture medium: add an appropriate amount of water to the culture medium to make it moist, adjust the pH of the culture medium to 6.0, then pour the culture medium into the seedling tray for later use, and adjust the pH value of the culture medium with dilute phosphoric acid, Sodium hydroxide solution;

[0025] 3. Cutting and disinfection of the bulb of the mother plant: take the evergreen cue ball, clean it, remove the outer layer of dry scales, put the bulb up, and cut the cue ball longitudinally from top to bottom into 20 pieces to ensure that each part has a bulb plate, and then soak these cut evergreen bulb slices in 500-fold diluted c...

Abstract

The invention belongs to the fields of plant cultivation techniques, landscape plants and ornamental horticulture and relates to a cutting propagation method for an ornithogalum caudatum ait bulb. In the technical scheme, turfy soil, perlite and vermiculite are mixed according to a certain proportion to form a cultivation medium for cutting propagation of the ornithogalum caudatum ait bulb, and differentiation growing and the reproductive rate of the cut ornithogalum caudatum ait bulb sections are improved by means of the technical conditions and methods of adjusting the suitable PH value of the medium, providing suitable cultivating temperature and humidity and the like. According to the cutting propagation method for the ornithogalum caudatum ait bulb, the cultivation medium for the cutting propagation is optimized, so that the cut ornithogalum caudatum ait bulb sections are in an excellent growing environment, differentiation growing and the reproductive rate of the cut ornithogalum caudatum ait bulb sections can be effectively improved, and the simple and practical technology for producing ornithogalum caudatum ait seedlings is provided for vast flower production enterprises.

Description

technical field [0001] The invention relates to a method for cutting and propagating a tiger's-eye evergreen bulb. The invention belongs to the fields of plant cultivation technology, garden plants and ornamental gardening. Background technique [0002] Evergreen tiger eye, also known as squill, bird's milk flower. It is a perennial herb of the Liliaceae evergreen genus, native to southern Africa. Bulbs ovoid, green, up to 10 cm in diameter. Leaves 5-6 pieces, band-shaped or strip-shaped-lanceolate, 30-60 cm long, 2.5-5 cm wide. As early as the 1970s, tiger-eye evergreen was introduced to China as an ornamental plant, and it was planted in Hainan, Xi'an, and Changbai Mountains. After the experimental research of many scholars, it was found that Dieffenbachia saponin (OSW-1 for short) was isolated from Dieffenbachia tiger's eye. In the physiological activity screening experiment, it was found that the in vitro anticancer activity of "OSW-1" was ten times or even a hundre...
