Cuihua Huilan's Cultivation Management Technology

First, temperature and environment Hulan flower growth temperature is 25-30 °C, the winter temperature is maintained at about 10 °C at night is more appropriate. Wedelia flowering blooms from February to March. If the temperature is less than 5°C. That affects the flowering. The biggest problem in planting Ceylon Whelan in the tropics is that the overwintering temperature is too high to form flower buds. In the hot summer season, it is best to transport Chuihua Huilan to high altitudes and cool climates in the high mountain areas and wait until flower buds emerge. Second, the cultivation of the substrate Hulan Huilan is a typical tropical epiphytic orchid, cultivation requires good root ventilation, cultivation matrix must be loose, water permeability and permeability, commonly used peat moss, ceramic particles, fern root, bark, coconut shell, etc. material. During operation, the pelvic floor is first filled with coarser hydrophobic materials such as broken bricks or plastic foam blocks, and the mixture of fern roots and 1 part of peat moss or other materials is used as a substrate. Mud pots. Third, watering and fertilizing Canghua Whelan in the spring of vigorous growth season requires adequate moisture and higher air humidity. Winter is a relatively dormant period of flower bud formation, and watering should be reduced to facilitate flower bud differentiation. In summer, due to the hot climate, the cultivation in the greenhouse must maintain good ventilation and ventilation, in addition to maintaining adequate humidity. Otherwise, poor growth, but also prone to rot. Cuihua Whelan in the growing season (three seasons in spring, summer and autumn) applies liquid fertilizer once a week, and can use nitrogen, phosphorus and potassium compound fertilizers for foliar spray or root application. The concentration is generally 0.1%. It can also be used after soaking in farmyard manure, such as water immersed peanut bran, but the concentration can not be too large.
