Method for regulating flowering period of phalaenopsis tissue culture seedlings

Abstract

The invention discloses a method for regulating the flowering period of phalaenopsis tissue culture seedlings. The method comprises the following steps that 1, roots of the phalaenopsis seedlings arewrapped in sphagna, placed in a 1.5 L nutrient bowl and cultivated in a greenhouse until new roots grow out, and then fertilization is conducted; 2, when the roots are completely wound in sphagna, the1.5 L nutrient bowl is replaced with a 3.5-inch nutrient bowl, and 10 days after bowl replacement, fertilization is conducted once every 10 days; 3, an abscisic acid solution is adopted for wateringthe roots of phalaenopsis plants to promote dormancy of the phalaenopsis plants; 4, 120 days before expected marketing and selling, flower buds are induced, a GA3 solution and a KH2PO4 solution are adopted for watering the roots of the phalaenopsis plants in the early stage of flower bud induction, a compound fertilizer solution is adopted for watering the roots of the phalaenopsis plants in the later stage of the flower bud induction, and after natural illumination in this stage is completed, a combined LED red-blue light source is adopted for illuminating phalaenopsis; 5, in a flower bud differentiation period, a 6-BA solution is adopted for watering the roots of the phalaenopsis plants. The method is adopted for regulating the flowering period of the phalaenopsis tissue culture seedlings to obtain phalaenopsis which has a controllable flowering time and neater and brighter flowers.

Description

technical field [0001] The invention relates to the field of flowering stage regulation, in particular to a method for regulating the flowering stage of Phalaenopsis tissue culture seedlings. technical background [0002] Phalaenopsis Bl.Spp. is named because of its large flowers, long flowering period, gorgeous flower color, rich color, beautiful and unique flower shape, dancing like a butterfly, and is known as the "Queen of Orchids" among tropical orchids. It is a popular high-end indoor potted flower in the flower market. [0003] The original place of Phalaenopsis is the subtropical rainforest area, likes humidity, is afraid of the cold and is afraid of the sun, its optimum growth temperature is 18~28 ℃, and the optimum growth humidity is 60%~90%. Because Phalaenopsis flowering requires specific conditions, such as temperature, light, hormones, etc., it needs to be regulated accordingly during artificial cultivation. [0004] Patent No. 200710064032.8 discloses a comp...
