Problems solved by technology

If it is planted in a larger pot, since the root system of Phalaenopsis is aerial roots, it is difficult to control the fertilizer and water after planting in a large pot, and it is very easy to have root rot. , the substrate sphagnum moss used has good water retention, so the contradiction between fertilizer and water and the air permeability of the substrate is prone to occur, or the lack of fertilizer is caused by the long interval between two fertilizers and water, or the root system is lacking due to excessive water content in the substrate. Oxygen and even necrosis
Both of these conditions will affect the growth of leaves, and ultimately affect the quality of flowering. Even if it can bloom on schedule, it will not reach the expected quantity and quality of flowering.
In addition, Phalaenopsis often has multi-flowers that are not proportional to the diameter of the pot, and the desired effect cannot be achieved.
[0004] Moreover, in the current production of large pots of Phalaenopsis, the management mode is single, and the homogeneity of products is serious. The pots are all nutritional bowls with a diameter of 11.5cm, and the number of flowers is not many, which has not been able to meet the high-end market's demand for large pots of fine Phalaenopsis.
In addition, the Phalaenopsis flowering technology is lacking in large pots. Under conventional management conditions, the age of Phalaenopsis seedlings is not directly proportional to the number of flowers. Sometimes the number of flowers in large pots is not as large as that of ordinary pots, and the flowering potential has not been fully utilized.
[0005] At present, Phalaenopsis seedling cultivation and flowering management technology have become the bottleneck of cultivation technology, restricting the development of Phalaenopsis industry

Embodiment 1

[0057] 90 pots of regular polyfloral seedlings 'Red Swan' (Doritaenopsis 'Red Swan') with regular growth and seedling age of 18 months were used, which were mature large seedlings originally planted in 11.5cm pots. The large seedlings were exchanged into 17cm plastic soft pots. The substrate is made of special A-grade sphagnum moss. After the pot was changed, the water was controlled for 20 days. During the period, 2000 times of open-root fertilizer with N-P-K of 5-11-26 and 9-45-15 was alternately sprayed on the foliage every 3 days, and the roots were not fertilized. 20 days later, when new roots grew, 45 pots (3 replicates, 15 pots for each replicate) were randomly selected as the treatment group, and the N-P-K content was 14-14-14 in the matrix, and the release period was 4. Monthly slow-release fertilizer 3 g / L substrate, re-burial after 3 months; the other 45 pots without slow-release fertilizer were used as the control group. The treatment group and the control group ...

Embodiment 2

[0065]Adopt 90 pots of Phalaenopsis seedlings identical with embodiment 1, and this seedlings are the mature big seedlings that were originally planted in 11.5cm pots. This big seedling is changed in the plastic soft basin of 17cm. The substrate is selected from special A grade sphagnum moss. After changing the pot, control the water for about 20 days. During this period, alternately spray 2000 times of N-P-K 5-11-26 and 9-45-15 root-opening fertilizers on the leaves every 3 days, and do not apply fertilizer to the roots. After rooting, 3 grams of slow-release fertilizer with an N-P-K content of 14-14-14 and a release period of 4 months was buried in the substrate. Apply water-soluble fertilizer with N-P-K content of 20-20-20 2-3 times a month, the EC value of water quality is lower than 0.3ms / cm, and the EC value of fertilizer solution is 0.8-1.2. Randomly get wherein 45 pots (3 repeats, each repeats 15 pots) as treatment group, after being planted into large pots, the firs...

Embodiment 3

[0073] Adopt 300 Phalaenopsis seedlings identical with embodiment 1, this seedling is the mature big seedling that is planted in 11.5cm pot originally. Change the Phalaenopsis seedling of 17cm pot, this big seedling is changed in the plastic soft basin of 17cm. The substrate is selected from special A grade sphagnum moss. After planting for 6 months under the environment of day / night temperature 25-30°C / 20-25°C, the flowering treatment is carried out. Select 180 seedlings that grow neatly and uniformly, and use day / night temperature 25-27°C / 16-18°C to promote flowering. After the stems are drawn, 180 orchid seedlings are randomly divided into 4 groups, with 45 plants in each group. Plant under different day / night temperatures as follows: 24-26°C / 15-17°C, 26-28°C / 17-19°C, 28-30°C / 19-21°C, 30-32°C / 21- 23°C. Other management is the same as that in the treatment group in Embodiment 2 above. Investigate and count indicators such as the number of days required for the pedicel to...

Abstract

The invention relates to a method for cultivating excellent large-potted butterfly orchid, which comprises the steps as follows: 1) planting a butterfly orchid seedling in a cultivating container with the diameter greater than 11.5 cm, and 2) performing buried application of slow-release fertilizer in a matrix after a new root begins to grow. The method is characterized in that: perferably, A), water-soluble fertilizer is applied in the matrix in a phased manner; B), an EC (electrical conductivity) value of the matrix is controlled to be 1.0-1.2 ms / cm; C), the daytime temperature and the night temperature are controlled at 25-28 DEG C and 15-19 DEG C respectively after a pedicel is extracted; and / or D), the matrix is washed with water or rich water with the EC value not greater than 0.3ms / cm every other 1-2 months after the new root grows. With the adoption of the large-potted butterfly orchid planting seedling, the large-potted butterfly orchid has a healthy and strong root system and tidy leaves, is plump in plant type, can sufficiently exploit blossoming potentialities, and can put forth above twenty flowers.

Description

technical field [0001] The invention relates to the field of flower cultivation, in particular to a method for cultivating Phalaenopsis. Background technique [0002] Phalaenopsis is a flower of the Orchidaceae Phalaenopsis. Phalaenopsis in a broad sense includes Phalaenopsis Phalaenopsis and Doritaenopsis. The latter is obtained by hybridizing the former with Doritaenopsis. They are native to tropical and subtropical regions and are known as the "Queen of Orchids" for their beautiful flower shapes. They are the world's largest-selling high-end potted flowers, and they are also the largest-selling New Year's Eve flowers in my country. [0003] The root system of Phalaenopsis is aerial, fleshy, and likes a humid and air-permeable environment. Conventionally cultivated Phalaenopsis is generally planted in a nutrient pot with a diameter of 11.5 cm or less in the final stage to promote flowering. If it is planted in a larger pot, since the root system of Phalaenopsis is aerial...
