specific Embodiment

[0021] Select plants with consistent growth and strong growth potential as test materials, and put them in a low-temperature greenhouse with a daily temperature of 25 °C and a night temperature of 20 °C, with a photoperiod of 12 hours of light, 12 hours of darkness, and a light intensity of 320 μmol m -2 ·s -1 , air humidity 70% to 80%. Continuous treatment for 6 weeks. The daily temperature of 25°C and the night temperature of 20°C can obviously promote the flower bud differentiation, but the temperature has an accumulation. The daily temperature of 25°C and the night temperature of 20°C can appropriately increase or decrease the temperature by 2-3°C, and at the same time appropriately extend or shorten the required time. Control time.

[0022] Catalan should use a high P fertilizer with a ratio of N:P:K of 10:30:20 to promote flowering. The dilution of the fertilizer is preferably about 1000 times, and the fertilizer should be applied once every watering. In addition, spr...

Abstract

The invention discloses a cattleya florescence regulating and controlling method. The selected cattleya plants are put into a greenhouse with a day temperature of 25 DEG C and a night temperature of 20 DEG C, photoperiod is set with a light period of 12h and a night period of 12h, a light intensity of 320 mu mol X m-2 X s-1 and an air humidity of 70%-80%, and the process continues for six weeks. High P fertilizer with a N:P:K ratio of 10:30:20 is applied for forcing the cattleya, and the plants are sprayed once each week by monopotassium phosphate aqueous solution diluted by 1000 times for improving cold resisting ability and in-vivo nutrient accumulation of the plants, and further improving the flowering. From September, the high P fertilizer is applied for forcing the cattleya, the cattleya is fertilized once after watering until the florescence is stopped. Therefore, the cattleya is abloom in time before holidays such as National Day, Spring Festival and the like, and the commodity value of the cattleya can be increased.

Description

technical field [0001] The invention relates to a florescence regulating technology, in particular to a method for regulating and controlling the flowering stage of cattleya. Background technique [0002] Cattleya (cattleya), also known as Cattleya orchid, is a plant of the genus Cattleya in the family Orchidaceae, an epiphytic compound stem orchid. It has colorful flowers, large and colorful flowers, fragrant and pleasant smell, and rich and colorful colors. It has the reputation of "king of orchids" in the world. It is native to tropical and subtropical America, among which Colombia and Brazil have the most wild and strong nature. Cattleya orchids are roughly divided into two categories: one is the single-leaved species, which usually have larger flowers and wider and more beautiful petals; the other is the double-leafed species, which has smaller flowers and narrow petals, but usually has more Bright colors. Cattelan is produced on a large scale in Thailand, Singapore,...
