Propagation management of bottle orchid

Xi Yang, slightly shady, like warm and humid zones.

Adjust water bottle orchid in the branch and leaf growth period, too much watering is easy to cause branches and leaves to grow, hinder flower bud differentiation; flowering water will hinder pollination and fertilization, easy to cause flower and fruit drop; too much water in young fruit development period, easy to cause physiological fruit drop; drought in fruit growth period will cause fruit withering. The bottle orchid should keep the soil moist properly during the whole growth stage.

The taproot of orchid in soil bottle is well developed, and the requirement of soil is not strict, but it is better to use loose and fertile medium. The ratio of cultivated soil is generally 4 parts of pastoral soil, 4 parts of sandy loam and 2 parts of rotten leaf soil. Properly add some bone meal and vegetable cake fat. It has a wide adaptability to soil alkali and acidity, and the ideal neutral partial acid ph value is between 6.5 and 7.0; the pot soil should be changed after two or three years of cultivation, and remember not to hurt the fibrous root.

Timely fertilization bottle orchids like fertilizer, water and fertilizer is applied every 7 days or so after the beginning of spring, thin fertilizer is applied frequently. The proportion is as follows: one part of fertilizer and 10 parts of water. Orchids need more nitrogen fertilizer in the branch and leaf growth period, and more phosphorus and potassium fertilizer in the germination stage and fruit development stage. Fertilize three times a year. Base fertilizer should be applied in mid-December in winter, accounting for 50% of the amount of fertilizer applied in the whole year. Topdressing once in July to promote flower bud differentiation and fruit hypertrophy. In September, topdressing made the plant strong and the fruit full and glossy. If there is no fertilization in winter, this kind of management can keep many flowers and full branches.

Sufficient light bottle orchids like light, the whole growth process needs sufficient light. Lack of light will cause branches and leaves to grow, affect flower bud differentiation, and easily lose fruit physiologically. Domestic bottle orchids should not be exposed to sunlight for less than 6 hours a day. Bottle orchid is a temperature-loving plant, but it has strong cold tolerance and is easy to survive the winter indoors in the south.

Most of the artificially pollinated bottle orchids are dioecious (few monoecious), and the parthenocarpy is weak. Bottle orchid should be equipped with pollination varieties, or collect male pollen for artificial pollination. Spraying 2.4-de-10ppm, or naphthylacetic acid 50ppm, or 920200 ppm at full flowering stage also had a certain effect on increasing the parthenocarpy rate of bottle orchids.

There are few diseases and insect pests, so we should mainly control the harm of shell insects.
