Problems solved by technology

To solve this problem, the traditional method is alpine flower urging, provided that the night temperature of the alpine flower urging base reaches 14°C or lower at the beginning of October, which requires a higher altitude in the alpine flower urging base, and the construction of the catalytic base Other requirements are often far away from the cultivation and production base, transportation and loss greatly increase the cost of finished flowers, and due to differences in natural temperature between years, resulting in differences in the effect of flower promotion in different years, which in turn affects Flower quality in different years

Embodiment 1

[0023] Select 20 plants of Dendrobium orchids with fully expanded leaves, without the treatment of the second stage of the first stage, directly placed in a greenhouse with a fan and water curtain for cultivation, as a control, the environmental conditions are the same as the third stage. After 112 days after the treatment, flowering began, the flowering rate of the plant was 85%, the average number of flowering nodes per pseudobulb was 4.9, the normal flowering rate of nodes was 47.6%, the number of flowers was 12.7 per pseudobulb, and the average flowering period was 34.8 days.

Embodiment 2

[0025] Select 20 Dendrobium plants with fully expanded leaves, without the first-stage treatment, and directly treat them with low night temperature in the cold storage for 30 days, the night temperature is 10°C, and the treatment time is 13 hours / day; Curtain greenhouse cultivation. After the treatment, it will start to bloom after 68 days of cultivation in the above-mentioned standard greenhouse. The flowering rate of the plant is 100%, the average number of flowering nodes per pseudobulb is 5.2, the normal flowering rate of nodes is 52.4%, the number of flowers is 9.5 per pseudobulb, and the flowering period is more than 42 days .

Embodiment 3

[0027] Select 20 Dendrobium plants with fully expanded leaves, and after the first stage of treatment, they will be treated at low night temperature in the cold storage for 30 days, the night temperature is 5°C, and the treatment time is 13 hours / day; during the day, they will be placed in a fan-water curtain greenhouse to cultivate. After the treatment was completed, it was cultured in the above-mentioned standard greenhouse for 72 days and began to bloom. The flowering rate of the plant was 100%, the average number of flowering nodes per pseudobulb was 7.3, the normal flowering rate of nodes was 63.3%, the number of flowers was 17.5 per pseudobulb, and the flowering period was 50 days.

Abstract

The invention discloses a dendrobium refrigerator flower forcing method. The method comprises selecting and cultivating plants with expanded branches and leaves in a fan cooling pad greenhouse for 60 days to prompt pseudobulbs to reach a full-maturity state; performing refrigerator low-night-temperature treatment for 30 days, placing the plants in a standard greenhouse with fans and cooling pads for cultivation in the daytime; after finishing the treatment, cultivating the plants in the fan cooling pad greenhouse for 68-72 days for flowering. The flower forcing rate of the plants can reach 100%, the number of flowering knots of every pseudobulb is 6.2-7.3, the number of flowers of every pseudobulb is 14.5-17.5, and the flowing phase of every pseudobulb is 42-50 days. The dendrobium refrigerator flower forcing method solves the problems such as difficult base site selection, high transportation cost, huge transportation losses and flower forcing quality difference of different years.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for promoting flowering of Dendrobium nobile. Background technique [0002] Dendrobium (Dendrobium) is the general name of Dendrobium in Orchidaceae. In horticulture, it is divided into spring Dendrobium and autumn Dendrobium according to its flowering time, flowering part and leaf persistence. Dendrobium dendrobium has beautiful flower shapes and postures, is gorgeous and colorful, has a wide variety of varieties, and has a long flowering period. Spring Dendrobium is more famous as an ornamental potted flower. Many varieties have both the beauty of Cattleya orchid and the fragrance of Chinese orchid, and the market potential is huge. [0003] Dendrobium dendrobium often blooms in spring, and the flowering period lasts for 1 to 2 months. There are certain markets all over the world, and there are more demands in Europe, America, Japan and South Korea. The do...
