preparation example 1

[0047] 1) Cross-pollination with Phal.Jiaho Cherry as the female parent and Phal.Lobbii as the male parent to obtain hybrid seeds;

[0048] 2) Cultivate the hybrid seeds (temperature is 28°C, relative humidity is 65%, light intensity is 10000lux) and select the optimal plants;

[0049] 3) Take the bud tip of the best plant and soak it in alcohol for 25 seconds for disinfection, and then put it on the primary medium (the primary medium is MS medium + 0.2mg / L folic acid + 2.5mg / L 6-BA + 1.3mg / L Mashed potatoes + 0.3mg / L ascorbic acid) for primary culture (cultivation time is 23 days, temperature is 25°C, light time is 11h / day, light intensity is 1800Lux) to obtain callus;

[0050]4) Take the base of the small shoots on the callus and cut them into small pieces, and then place them in the subculture medium (the subculture medium is MS medium + 0.2mg / L ABA + 1.9mg / L 6-BA + 0.4mg / L penicillin + 20g / L sucrose + 6g / L agar) for subculture (cultivation time is 29 days, temperature is...

Abstract

The invention discloses a cultivating method for increasing the flowering rate of unfolded phalaenopsis aphrodite Rchb. F. of cherries. The method comprises the steps of a, planting seedlings of phalaenopsis aphrodite Rchb. F. of the cherries under the illumination of 8,000-12,000 lux to be cultivated for 5 months to obtain small seedlings; b, putting the plantlets under the illumination of 12,000-15,000 lux to be cultivated for 1 month to obtain intermediate seedlings; c, putting the intermediate seedlings under the illumination of 15,000-18,000 lux to be cultivated for 2-3 months to obtain large seedlings; d, transferring the large seedlings into a cold chamber to conduct flower bud induction and flowering accelerating until flowering is achieved, wherein the day temperature in the coldchamber is 21-23 DEG C, and the night temperature is 17-19 DEG C. A cultivating method for unfolded phalaenopsis aphrodite Rchb. F. of the cherries comprises the following steps of 1, conducting crosspollination with phal.Jiaho cherries as female parents and phal.Lobbii as male parents to obtain hybrid seeds; 2, cultivating the hybrid seeds to select optimal plants; 3, conducting tissue cultivation on the optimal plants to obtain unfolded phalaenopsis aphrodite Rchb. F. of the cherries. By means of the cultivating method, unfolded phalaenopsis aphrodite Rchb. F. of the cherries can have the excellent flowering rate.

Description

technical field [0001] The invention relates to a cultivation method of Phalaenopsis, in particular to a cultivation method for improving the flowering rate of the spreading cherry Phalaenopsis. Background technique [0002] Phalaenopsis aphrodite Rchb. F. belongs to the genus Phalaenopsis Phalaenopsis. It is native to subtropical rainforest and is an epiphytic orchid. The thick white aerial roots of Phalaenopsis are exposed around the leaves. In addition to absorbing nutrients in the air, they also have growth and photosynthesis. In the Spring Festival, the Phalaenopsis plants have long flower stalks from the leaf axils and bloom like butterflies. They are favored by flower lovers and are known as the "Queen of Orchids". Distributed in Thailand, Philippines, Malaysia, Indonesia, and Taiwan. [0003] Although the existing Phalaenopsis has numerous varieties, there are still no pulverized red lips of small flowers, the varieties with excellent flower type and good bifurca...
