Problems solved by technology

The side ball propagation method in traditional production, because there are only 2-3 'buds' growing around the cue ball of the biennial scale ball, the multiplication coefficient is low, and it cannot meet the needs of rapid promotion of improved varieties

Embodiment 1

[0025] An improved method for propagating narcissus side bulbs:

[0026] 1) Preparation of basic propagation materials: direct planting of uncastrated 'seedlings' of 'Jinzhan Yintai', conventional field management, erasing all the outer small bulbs when harvesting in June, leaving the female bulb bulbs, and storing after drying ;

[0027] 2) From July to September, during the daytime, place the mother bulb as the propagation material in a seedling treatment room with temperature control equipment for high temperature treatment, and maintain a micro-ventilated environment, control the temperature to 37°C and maintain the temperature for 8 Hours, then stop heating, and naturally drop to room temperature; during this period, the time of variable temperature treatment is 40 days, no less than 10 days in each month, and stimulate the germination activity of bulb discs through adversity and high temperature stress, and promote tillers to produce more buds point;

[0042] An improved method for propagating narcissus side bulbs:

[0043] 1) Basic propagation material preparation: direct planting of 'Grand Soleil d'Or' uncastrated 'seedlings', conventional field management, wipe off all the outer small scales when harvesting in June, leave the mother bulb, dry and routine storage;

[0044] 2) From July to September, during the daytime, place the mother bulb as the propagation material in a seedling treatment room with temperature control equipment for high-temperature treatment, and maintain a micro-ventilated environment, control the temperature to 36°C and maintain the temperature at 8.5°C. Hours, then stop heating, and naturally drop to room temperature; during this period, the time of variable temperature treatment is 38 days, no less than 10 days in each month. Stimulate the germination activity of the bulb disc through high temperature stress, and promote tillering to produce more bud points;

Abstract

The invention discloses an improved method for lateral bulb propagation of narcissus. The method comprises the following steps of (1), directly planting seeds which are not castrated, removing all small scale bulbs at the outer side during harvesting in June, and leaving mother bulbs; (2) from July to September, performing high-temperature treatment on the mother bulbs in the daytime, controllingthe temperature to be 36-38 DEG C, keeping the temperature for 7.5-8.5 hours, and then naturally cooling the mother bulbs to room temperature; (3) in October, in the daytime, performing low-temperature treatment on the mother bulbs, controlling the temperature to be 5-10 DEG C, keeping the temperature for 7.5-8.5 hours, and then naturally cooling the mother bulbs to the room temperature; (4) in November, storing the mother bulbs at the room temperature; (5) in December, planting the mother bulbs as seed bulbs; and (6) after harvesting in June of the second year, storing the mother bulbs to autumn, and separating all the small scale bulbs as seedlings. According to the method, temperature-changing treatment is carried out in the bulb storage process, bud points on a bulb pan are promoted togerminate and grow into effective cormels, meanwhile, measures such as planting delaying and proper shallow planting are combined, and a proper amount of bulb slice nutrients are further consumed, sothat the purposes of more germination and increase of the number of the small scale bulbs are achieved.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to an improved method for propagating side balls of narcissus. Background technique [0002] Narcissus is a perennial herbaceous plant of the genus Narcissus in the family Amaryllidaceae. At present, the lack of cultivated varieties and single flower color have become the main "bottleneck" for the sustainable development of the domestic daffodil industry. In order to overcome the restrictive factors of the single main species of narcissus in my country, we collected domestic and foreign narcissus germplasm resources, carried out introduction and domestication, and screened out some good varieties suitable for cultivation in Zhangzhou's main production areas, such as 'Avalanche', 'Grand SD'Or ', 'Golden dawn', 'Winter Sun', 'Golden rain', 'chinese sacred lily', etc. The research and development of efficient and high-quality breeding technology is of great significance to ...
