Dendrobium nobile plant height 30 to 100 cm, upright pseudobulb was flat cylindrical, often more pseudobulb clustered together. The flowering period is from March to April, with purple, red, yellow, yellow, white and milky white. Its cultivation and management techniques are as follows:
First, the temperature and the cultivation site in the north cultivation spring Dendrobium winter in the indoor winter, room temperature above 5 °C, it is best to have sufficient sunlight. Move to outdoor cultivation in the spring and pay attention to shelter from rain and ventilation in summer. The well-developed bulbs are given at an appropriate low temperature for 2 to 3 weeks in the late autumn and early winter to promote flower bud differentiation. After flower buds are grown, they are kept at a suitable room temperature, 20 to 25°C during the day and 15°C at night.
Second, the light Chun Shi Xi happy sunshine, spring, summer and autumn three strong sunshine is conducive to its vigorous growth, the shading should be about 30 to 50%. Plants after flowering should not be placed in a place with too much sunlight, otherwise the flowers will fade prematurely. It is also not suitable for areas where the light is dark, which will reduce the color and shorten the flowering period.
Third, watering spring stone moss hi acidic to neutral water, avoid water containing too much calcium, magnesium and other minerals. The early period from spring to summer is the period of vigorous growth of spring sarcophagus, and it needs sufficient moisture. After entering the dormancy period, the amount of watering is reduced, but the higher humidity in the air needs to be maintained. The flowering plants are watered when the surface of the substrate is dry, and do not spray water on the flowers.
Fourth, the growth of the potted matrix of spring sarcophagus requires the root soil to be breathable and well drained. Pots are good for pots and mosses are used as a base. The bottom of the pot is filled with granules for the drainage layer. Moss should be tightly packed when planting. At the same time, attention should be paid to replacing the new moss every year, or the moss will deteriorate with long-term permeability and permeability.
5. Fertilization Fertilizers mainly supplied with nitrogen fertilizer should be fully supplied during the spring seedling stage and spring and summer vigorous growth period. After the flowers were opened, fertilizers containing high nitrogen content were applied until the end of July. From August to September, fertilizers with high P and K contents were used. The organic fertilizer that can be applied to the surface of the bowl is once every 3 weeks. Foliar can also be sprayed or irrigated with liquid fertilizer at a concentration of about 2000 times. Foliar spraying is best once a week. Fertilizer should be applied as much as possible to reduce the amount and frequency of organic fertilizer, because it can easily cause moss rot. In addition, during the period of dormancy until the flowering period of Dendrobium nobile, all fertilizers should be stopped.
