Cultivation and Management of Phalaenopsis

1. Plant material: plant material should be put at the bottom of the basin when planting, at least 1 to 2 pots. The material is made of water moss (suitable for medium and small seedlings), whole snake sawdust and snake sawdust plus water moss or half of snake sawdust and charcoal particles, and the effect is very good. Others such as vermiculite, cement charcoal soil, Alsophila spinulosa root, coconut shell grains can also be used as plant materials.

two。 Watering: Phalaenopsis is native to primeval forests with high humidity. And there is no thick pseudo-corm to store nutrients and water. Therefore, Phalaenopsis should be cultivated and maintained in an environment with high ventilation and humidity. The optimum humidity is 70% during the day; the humidity can be slightly reduced at night, especially during flowering. Water more in the peak growth period and less in the dormant period after anthesis. Watering is done around 05:00 every afternoon in spring and autumn; plants grow vigorously in summer, watering at 09:00 and 05:00 every day; and watering every other week is enough for weak light and low temperature in winter, which should be carried out before 10:00 In the event of a cold wave, it is not suitable to water, keep dry, wait until after the cold wave to resume watering.

3. Lighting: Phalaenopsis needs less light than ordinary orchids. For outdoor training, the luminosity required is about 40% of that of full-day sunlight. Avoid direct glare. Shading can be carried out in different seasons according to the intensity of sunlight, 80% in summer, 60% in autumn and 40% in winter. The method of shading is to use a shading net with a suitable shading rate. If you use strips of wood or bamboo, the effect is also very good. In places where the average annual light is less, shade can be reduced as appropriate. Indoor cultivation, as long as 600 color 1000 candlelight intensity of light on the line.

4. Temperature: the suitable temperature for the growth of Phalaenopsis is 20 ℃ 30 ℃, the temperature is above 18 ℃ at night and 26 ℃ during the day. It should not exceed 35 ℃ in summer and 10 ℃ in winter, otherwise the growth would be inhibited and the flower bud differentiation should be less than 18 ℃. After differentiation, the temperature should be raised to 20 ℃ and 25 ℃, so as to induce the rapid growth of pedicel.

5. Fertilization: nitrogen fertilizer is the main fertilizer before enlightening, suitable for the application of rotten bean cake water, the concentration is 20%, once every two weeks. When it is about to blossom, it is mainly phosphorus and potassium fertilizer, suitable for the application of rotten chicken and duck manure fertilizer, the concentration is 20%, once every ten days. During the growing period, the prepared nitrogen, phosphorus and potassium mixed dilute liquid fertilizer can also be used to spray an appropriate amount of foliar once a week. The time to fertilize is after watering in the afternoon. After applying several times, rinse orchid pots and orchid plants with a large amount of water to avoid residual inorganic salts harming the roots.
