Problems solved by technology

After flower urging in alpine bases, the cost of a single finished Phalaenopsis will increase a lot; low temperature flower urging by fans and water curtains on flat land will not drop low enough in summer, and the low temperature time is not long enough, resulting in a low rate of urging flower stalks. The time to draw stems is slow, and the quality of finished flowers will also deviate

Abstract

The present invention relates to a method for cultivating phalaenopsis amabilis in a northern glasshouse. The method comprises the following steps: planting phalaenopsis amabilis seedlings in a matrix (a mixture of peat soil and perlite according to a volume ratio of 4:1 to 5:1); thoroughly watering the whole matrix with water having a pH value of 6.0-6.8; spraying the plant with a 800-time liquid of chlorothalonil wettable powder 2-4 days after watering; transferring the mature phalaenopsis amabilis seedlings into a greenhouse 4-5 months before expected flowering; keeping temperature of the greenhouse at 30-32 DEG C during daytime and at 24-26 DEG C during night; adjusting illumination in the greenhouse to 10000-12000 Lux; and applying fertilizers at regular intervals, wherein a balance fertilizer with a N:P:K ratio of 20:20:20 is applied every week along with water.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for cultivating Phalaenopsis in northern greenhouses. Background technique [0002] Phalaenopsis belongs to Orchidaceae Phalaenopsis, formal name used at school Phalaenopsis amabilis. It is native to tropical and subtropical alpine regions of Asia, and is distributed in Taiwan, the Philippines, Java and other islands. Phalaenopsis is an evergreen herb with short stems, large leaves, one to several flower stems, arched, large flowers and butterfly shape. Shade-tolerant and heat-loving, it is a temperature-sensitive flower, suitable for growing in a warm and ventilated environment. The required luminosity is about 40% of the full sun, the relative humidity is 70%, and the temperature is 15°C-30°C. Phalaenopsis is shaped like a butterfly and has bright colors. It is a treasure among tropical orchids and has the reputation of "Queen of Orchids". The common Phal...
