Problems solved by technology

"Shenma" is one of the main varieties of cut chrysanthemums. When exporting to foreign countries, the length of the flower stem is usually required to be 900mm. When the cut chrysanthemums are cultivated in off-season, due to the short light time, the cut chrysanthemums will end the vegetative growth period prematurely. , so that the height of the cut chrysanthemum is insufficient, and the number of petals is also small, which cannot meet the customer's requirements

Embodiment

[0008] A method for cultivating cut chrysanthemums using photoperiod regulation technology, comprising the following steps: (1) planting: planting and watering well-rooted chrysanthemum seedlings in the morning or evening; Sunshine, the daily sunshine time is more than 13h. If the daytime sunshine time is insufficient, artificial supplementary light shall be carried out from 22:00 in the evening to 02:00 in the morning of the next day. The light intensity shall be above 55lux to meet the light time until the plant grows to 500mm (3) Illumination control during the reproductive growth period: keep short sunshine, and the daily sunshine time is not more than 11 hours. If the sunshine time is more than 11 hours, shade in the evening or morning. By adopting photoperiod regulation technology, the flowering period can be adjusted and the life of cut chrysanthemum can be extended. During the vegetative growth period, the height of cut chrysanthemums can reach 900mm to 1000mm, which no...

Abstract

The invention discloses a method utilizing a light cycle control technique to cultivate chrysanthemum morifolium, and relates to the technical field of cultivating of out-of-season chrysanthemum morifolium. The long sunlight time is provided in the vegetative growth phase, namely that the sunlight time is longer than 13 hours each day. If the natural sunlight time is not enough, the light is manually supplemented at night, and then the vegetative growth period of the chrysanthemum morifolium is prolonged. After the height of the chrysanthemum morifolium reaches 500nm, the short sunlight time is provided, namely that the sunlight time is shorter than 11 hours, and then the chrysanthemum morifolium enters the reproductive growth period. By matching with the techniques of sprout picking, bud picking and the like, the growth height of single chrysanthemum morifolium can reach 900mm to 1000mm, so the height of the chrysanthemum morifolium can meet the requirement of a customer, the flower period can be adjusted, and the sustained supply of the chrysanthemum morifolium on market can be ensured by the out-of-season cultivating of chrysanthemum morifolium.

Description

technical field [0001] The invention relates to the technical field of off-season cut chrysanthemum cultivation, in particular to a method for cultivating cut chrysanthemums using photoperiod regulation technology. Background technique [0002] Chrysanthemum is native to my country and has a long history of cultivation and application in my country. It is one of the traditional four famous flowers in my country. It has been widely planted because of its rich varieties, ever-changing flower patterns and colors, and strong ornamental value. "Shenma" is one of the main varieties of cut chrysanthemums. When exporting to foreign countries, the length of the flower stem is usually required to be 900mm. When the cut chrysanthemums are cultivated in off-season, due to the short light time, the cut chrysanthemums will end the vegetative growth period prematurely. , so that the height of the cut chrysanthemum is insufficient, and the number of petals is also small, which cannot meet t...
