How to fertilize Phalaenopsis in Family cultivation

Phalaenopsis is a tropical epiphyte orchid. The cultivation medium selects water-retaining and breathable plants, such as fire bricks, coconut shells, charcoal blocks, fern roots or snake boards, etc., and is cultivated in a semi-shade place with 50%~70% shading. Summer to prevent high temperature, sultry, strengthen ventilation, maintain 70%~80% air humidity; winter should pay attention to prevent low temperature cold damage.

Phalaenopsis mainly depends on topdressing to promote plant growth, so in its growing season, spraying nitrogen, phosphorus and potassium fertilizer or potassium dihydrogen phosphate with a concentration of 0.1%~0.3% once a week, as well as pesticides such as stone sulfur mixture, carbendazim, thiophanate-methyl, etc. to prevent and cure diseases.

1)Phalaenopsis greenhouse cultivation: available soilless substrate cultivation, soil can also be planted. Soilless substrate can be moss, peat, bark, etc., Yunnan several companies with moss as substrate potted, with nutrient solution and water fertilizer, the effect is better.

(2)Phalaenopsis ground culture substrate can be selected peat, pearlite, rotten leaf soil and appropriate red soil preparation, and after steam disinfection use. The greenhouse should be made into a planting bed 1.2 meters wide and 20-25 cm deep. The bed should have good drainage and ventilation conditions. It is best to build a high bed isolated from the ground. culture substrate is placed in the bed. Greenhouse should be equipped with ventilation equipment, shading equipment, spraying equipment, heating equipment and spray drip irrigation equipment.

(3)The planting density of Phalaenopsis is 20-32 plants per square meter, with equal spacing. After planting, watering should be carried out by spraying water. Soft water should be used to prevent scale from affecting the growth of leaves. Spraying water not only watered the plants, but also increased the air temperature, which was beneficial to the growth and development of the plants.

(4)Phalaenopsis fertilization is basically combined with watering, generally a large number of elements and trace elements dissolved in water in proportion, adjust the pH to slightly acidic, and then spray the whole plant 1-2 times a week, the concentration of 0.1%-0.2%, the best use of plants can be directly absorbed fertilizer.

(5)According to the ecological habits of Phalaenopsis, adjust the most suitable light, temperature, humidity, and keep the environment ventilated. Creating an optimum environment for growth and development of Phalaenopsis is an important condition to ensure the yield and quality of cut flowers.

(6)Phalaenopsis pruning: When flowering plants, sometimes the top of the pedicel droop phenomenon, can be used to support bamboo. Such as potted ornamental, but also available wire support, specifically bent the upper part, so that flowers have a certain shape, thus improving the ornamental. In addition, the plants planted on the ground should be cleared of peripheral dead leaves in time and burned intensively to prevent bacterial infection.

(7)Phalaenopsis main diseases and insect pests: bacterial soft rot, spot disease, gray mold, anthracnose, blight, slugs, etc., to strengthen control. Cut flower harvesting: when the base of the flower inflorescence open 2-3 flowers for the harvest appropriate period, the cut flowers collected sorting classification after single branch packaging, boxing market. If you want to store, because Phalaenopsis is afraid of low temperature, it should be stored at not less than 13℃ to avoid freezing damage.

Phalaenopsis humidity: Phalaenopsis like higher air humidity, growth period should be maintained at 70%-80%, therefore, should often spray water to the surrounding space to increase humidity, but the moisture of the substrate should not be too large, otherwise easy to rot roots, slightly dry substrate conducive to the growth of new roots.

Phalaenopsis illumination: open the shade net in time according to the weather conditions every day to promote the photosynthesis of Phalaenopsis, and open the skylight to ventilate when the temperature is higher or the humidity is too high. Phalaenopsis fertilization: Phalaenopsis fertilization adhere to the principle of "thin fertilizer and frequent application", can be 1500 times compound fertilizer and 5000 times boric acid mixed spray, after every other week to apply 1500 times compound fertilizer, in addition to Phalaenopsis for fleshy roots, to make its roots plump, potassium fertilizer application is more important.

Light and shade

Outdoor orchid cultivation needs shading, 70%~80% shading in summer, 50%~60% shading in spring and autumn, 40%~50% shading in winter. Shading materials are shading nets, curtains, or self-made battens, bamboo shelves. Self-made shade shelf should be 4~5 cm wide, interval 3.3~4 cm, frame on the orchid basin about 1 meter.
