A complete collection of breeding methods and matters needing attention for heavy snow elements
Known as the "Queen of Dianlan", Xueyu is favored by gardening enthusiasts for its elegant flower appearance and quiet aroma. This orchid variety from the mountains of Yunnan requires special cultivation skills in family potted maintenance to make it bloom charming on the windowsill and desk. The key period for temperature control of the three major factors of environmental control is 15-28℃, which is the best growth temperature zone. When it exceeds 30℃ in summer, cooling measures need to be initiated. It is recommended to use a double-layered sunshade net combined with a spraying device to control the leaf surface temperature within a safe range. Maintaining above 5 ° C in winter can safely survive the winter. Heating households in the north need to pay attention to staying away from radiators. The art of light and shadow balance adopts the combination mode of "morning light + scattered light". It can accept direct light for 2 hours in the morning, and a gauze curtain with a light transmittance of 60% is used to filter strong light during the rest of the time. Rotate the flowerpot regularly to ensure uniform light reception and avoid plant growth on the wrong side. The humidity management system is equipped with a basin system with a water level line to achieve humidity buffering through the ceramsite layer. Keep the substrate moist in spring and autumn without accumulating water. Spray in the morning and evening in summer to increase humidity, and change to weekly dipping basin method to replenish water in winter.

Adopt the principle of "thin fertilizer and frequent application", and use special fertilizer for orchids and decomposed rice washing water alternately every half month during the growth period. Add phosphorus and potassium fertilizers before budding, and it is recommended to use seaweed extract diluent for foliar topdressing. Operation specifications for pot replacement: bark, volcanic rock, and leaf soil are selected to replace pots in a ratio of 4:3:3 every spring. Reserve 1/3 of the heart soil during operation, prune the long old roots and apply plant ash to disinfect them. After changing the pot, place them in a cool place to slow down for two weeks. The key point of rate-breeding is to select a strong mother plant for more than 4 years old and cut it at the natural tillering point of the false bulb. Keep more than 3 seedlings per clump, and apply cinnamon powder to the incision to prevent bacteria. Wrap the incision with water moss for transitional culture, and transplant after new roots germinate. Pest and pest control strategies Identification of common diseases
