Problems solved by technology

Due to the limitations of foreign bulb harvesting time and uncertain factors in the field of trade and circulation, as well as the lack of understanding of the characteristics of tulip varieties, the application of tulip cultivation technology in China is still in its infancy
In addition, since the imported bulbs have completed post-harvest treatment and flower bud differentiation before being exported to my country, the post-harvest treatment technology of tulip bulbs in China has not been fully mastered, and only a few scientific research institutes have carried out preliminary research work

Embodiment 1

[0027] (1) Harvesting and grading of bulbs: Properly control the water of the plants after flowering, so as not to cause the bulbs to rot due to too high soil humidity. Harvest the bulbs when 2 / 3 of the plant leaves are close to withered and yellow, such as figure 1 As shown, and graded according to the size of the bulb circumference (circumference>12cm, first-grade bulbs; 12cm>circumference>11cm, second-grade bulbs; 11cm>circumference>10cm, third-grade bulbs; 10cm>circumference>8cm , four-level ball; circumference <8cm, five-level ball).

[0028] (2) Disinfection of bulbs: Soak bulbs with 1000 times of 50% carbendazim WP or 70% thiophanate-methyl WP for 20-30 minutes, then rinse with water, place in a cool and dry place, and dry Then move indoors for flower bud differentiation.

[0029] (3) Post-harvest treatment of bulbs and flower bud differentiation: Put the bulbs indoors for flower bud differentiation, keep the room temperature at 20-25°C, and air humidity at 60%-70%, an...

Abstract

The invention discloses a post-harvesting treatment and forcing culture method for seed bulbs of tulipa gesneriana. The method comprises the following steps of 1, harvesting the seed bulbs of the tulipa gesneriana and preliminarily treating the seed bulbs; 2, putting the seed bulbs of the tulipa gesneriana in an environment with the temperature of 20-25 DEG C and the air humidity of 60-70% for post-harvesting treatment, and observing the flower bud differentiation situation until differentiation of pistils is finished; 3, conducting cold treatment on the seed bulbs under the condition of 3-8 DEG C for 3-12 weeks; 4, stripping bulbus skin at bulbus roots of the seed bulbs, then planting the seed bulbs in culture soil or culture liquid, and conducting shading culture for 4-6 days in an environment of 10-15 DEG C; 5, putting seedlings of the tulipa gesneriana in an environment of 20-25 DEG C for culture, and conducting seedling-stage growth and flower forcing under the lighting conditionof 16 hours of lighting treatment and 8 hours of dark treatment every day. By means of the method, two growth stages of post-harvesting treatment and forcing culture of the seed bulbs of the tulipa gesneriana are integrated, and the method is suitable for out-of-season cultivation, significantly shortens the growth period of the tulipa gesneriana, and increases the utilization rate and economic benefit of the seed bulbs of the tulipa gesneriana.

Description

technical field [0001] The invention relates to the technical field of flower cultivation, in particular to a post-harvest treatment and cultivation method for tulip bulbs. Background technique [0002] Tulip (Tulipa gesneriana) is one of the important ornamental plants of Liliaceae. It is loved by people because of its large flowers and rich and gorgeous colors. It is widely used in garden landscapes and is also one of the main fresh cut flowers in winter and spring in my country. Tulips are native to Central Asia and Asia Minor, and the Zhaosu region in Xinjiang, my country is also one of the origins of tulips. Since it was introduced into Europe, after hundreds of years of cultivation in the Netherlands and other places, tulips have gradually adapted to the subtropical Mediterranean climate with cold and humid winters and hot and dry summers. Vegetative growth begins to form stems and leaves around early February of the second year, and blooms in March to April. The opti...
