Pineapple flowering phase precise regulation and control preparation and use method thereof

Abstract

The invention relates to the technical field of pineapple crossbreeding, and particularly discloses a precise pineapple flowering phase regulation and control preparation which comprises a flowering phase advanced regulation and control agent which is an aqueous solution. The flowering phase advanced regulating agent is prepared from the following raw materials in parts by weight: 3 to 8 parts of 6-benzylaminopurine, 1 to 4 parts of gibberellin, 3.5 to 8 parts of monopotassium phosphate, 2 to 7 parts of alginate oligosaccharide, 1 to 4 parts of catechin, 0.5 to 3 parts of calcium chloride, 3 to 8 parts of glucose, 30 to 50 parts of ethanol and 100 to 150 parts of water. The precise pineapple flowering phase regulation and control preparation has the effect of bidirectionally regulating and controlling the pineapple flowering phase, and different varieties can be induced to simultaneously bloom by regulating and controlling the component proportion and concentration. The method is also beneficial to formation and development of pollen, can ensure the fertility and pollen quantity of the pollen after the flowering phase is regulated and controlled, and is beneficial to improving the effect of crossbreeding.

Description

technical field [0001] The invention belongs to the technical field of pineapple crossbreeding, and in particular relates to a pineapple flowering period precision control preparation and a use method. Background technique [0002] Pineapple is a perennial herbaceous plant belonging to Bromeliaceae. Pineapple fruit has a unique flavor and rich nutrition. It can be eaten fresh or made into cans and juices. It has important economic value and is the third largest tropical fruit in the world after bananas and mangoes. In recent years, my country's pineapple planting area and output have steadily increased, and the pineapple industry has become an important pillar industry of my country's tropical agriculture. The pineapple varieties used in my country's production are mainly the queen-type Bali species introduced many years ago. The single variety and the degeneration of the main species have become the primary factors that seriously restrict the healthy development of my count...

Problems solved by technology

At present, ethephon is mainly used as flower urging agent for artificial flowering of pineapples. In my country’s main pineapple producing areas such as Guangdong, Guangxi, and Hainan, in order to increase cultivation income, farmers often use ethephon to urge flowering in off-season in autumn to promote early fruit production. Mature, but using ethephon to promote flowering and then cross breeding has different effects on different varieties of flowering, resulting in inconsistent flowering periods of different varieties, low pollen quantity of flowering plants, pollen abortion, resulting in hybrid seeding rate much lower than natural flowering plants, etc., which is very bad for crossbreeding
