Flowering from April to May, most of them are dioecious and occasionally monoecious, and the fruit ripens in September 9- 10/October.

Golden marble is mainly distributed in southern provinces, concentrated in Sichuan, Chongqing, Guizhou, Hunan, Hubei and other places. There are many lobules in Sichuan, and there are three kinds of golden marbles in Hubei: big leaf, middle leaf and lobule.

cultivation techniques

1, moisture

Regulating the growth period of Aquarius orchids in branches and leaves, too much watering will easily lead to long branches and leaves, which will hinder the differentiation of flower buds; During flowering, water will hinder pollination and fertilization, which will easily lead to falling flowers and fruits; Too much water during the development of young fruit is easy to cause physiological fruit drop; Drought during the fruit growing period will cause the fruit to wither. Bottle orchids should keep the soil properly moist during the whole growth stage.

2. Land

Choose soil. Orchids have developed straight roots, which have low requirements for soil, but loose and fertile media are better. The proportion of cultivated soil is generally 4 parts pastoral soil, 4 parts sandy loam soil and 2 parts humus soil. Add some bone meal and vegetable cake fertilizer appropriately. Widely suitable for alkaline acidity of soil, and the ideal ph value of neutral acidity is between 6.5 and 7.0; Change the pot soil after two or three years of cultivation, and remember not to hurt the fibrous roots.

Step 3 apply fertilizer

Orchids should be fertilized in time, watered and fertilized every 7 days after spring, and thin fertilizer should be applied frequently. The ratio is: 1 fertilizer, 9 9- 10/water. Bottle orchid needs more nitrogen fertilizer in the growth period of branches and leaves, and more phosphorus and potassium fertilizer in the germination period and fruit development period. Fertilize three times a year. Base fertilizer should be applied in winter from May 438 to mid-February, accounting for 50% of the annual fertilization. Topdressing once in July promotes flower bud differentiation and fruit hypertrophy. Top dressing once in September, the plants are strong and the fruits are full and shiny. No fertilization in winter, management can ensure more flowers and full branches.

4. Lighting equipment

Sufficient light bottle orchids like light, and the whole growth process needs sufficient light. Insufficient light will cause long branches and leaves, affect flower bud differentiation, and easily cause physiological fruit drop. Domestic bottle orchids should be exposed to the sun for no less than 6 hours every day. Orchids are warm-loving plants, but they have strong cold tolerance and are easy to overwinter indoors in the south.

Step 5 pollinate

The artificially pollinated orchids are mostly hermaphroditic (rarely hermaphroditic), and the parthenogenesis intensity is weak. Bottle orchids should be pollinated, or male pollen should be collected for artificial pollination. Spraying 2.4-de- 10ppm, or 50ppm of NAA, or 0.200 ppm of NAA at the 92nd full flowering stage can also improve the parthenocarpy rate of Cymbidium grandiflorum.

prune

Orchid vases are good materials for making bonsai. According to its growth condition, proper pruning is helpful to improve its ornamental value.
