Flowering phase regulating method for delaying flowering time of cuckoo

Abstract

The invention belongs to the technical field of flowering phase regulation and discloses a flowering phase regulating method for delaying flowering time of cuckoo. The flowering time of cuckoo is delayed by regulating the flowering phase in the squaring stage by means of a method of joint action of shading and abscisic acid. The light period is an important induction factor for blossoming of plants and is the most direct and effective outer factor for inducing bud formation. Mitogenetic action and blossoming of flowers can be induced as each plant need a certain length of day and correspondinglight length mutual alternation, and the flowering phase is regulated by controlling the lighting period. The abscisic acid is a substance for inhibiting growth of the plant, can promote ageing, dormancy and organ falling of ornamental plants, and can place the action of short-day and promote or inhibit blossoming of the ornamental plants. The cuckoo is a long-day plant and can generate buds andblossom by requiring more than 12 hours lighting commonly, so that the flowering time of the cuckoo is regulated by controlling the lighting period and the abscisic acid, and the demand on the flowering time of the cuckoo in the market is met.

Description

technical field [0001] The invention belongs to the technical field of flowering regulation, and in particular relates to a flowering regulation method for delaying the flowering time of Rhododendron. Background technique [0002] At present, the commonly used prior art in the industry is as follows: Rhododendron is a general term for Rhododendron in Rhododendronaceae, and it is customarily divided into four categories in my country: Rhododendron, Eastern Cuckoo, Summer Cuckoo, and Western Cuckoo. Because of its high ornamental value, it enjoys the reputation of "beauty among flowers". Rhododendrons are widely distributed, from tropical, subtropical, temperate, north temperate to frigid, and their vertical distribution ranges from coastal rocks or mangroves close to sea level to places with the highest altitude of 5500m. Data show that my country is the country with the richest wild rhododendron resources, and the southwest to central regions of my country are most likely t...

Problems solved by technology

[0004] To sum up, the problems existing in the existing technology are: at present, the flowering regulation of Rhododendrons in the market is mostly used for potted Western Rhododendrons, and greenhouses, greenhouses and other facilities are used for temperature control to achieve the purpose of flowering regulation, and the cultivation manageme
