Last Updated: 2024/11/05, Phalaenopsis needs to be cultivated in high temperature greenhouse in winter in north China. In order to create suitable environmental conditions for the growth of Phalaenopsis, the following aspects should be done well: First, temperature: the appropriate temperature for the growth of Phalaenopsis is 25℃-30℃ during the day, more than 32℃, unfavorable for growth and flower bud differentiation, 18℃-20℃ at night, not lower than 15℃, if it has been maintained at a higher temperature, it is conducive to its flowering. Humidity: Phalaenopsis likes higher air humidity and should be kept at 70%-8 during growth.

Phalaenopsis needs to be cultivated in high temperature greenhouse in the north in winter. In order to create suitable environmental conditions for the growth of Phalaenopsis, we should do a good job in the following aspects:

1. Temperature: the optimum temperature for the growth of Phalaenopsis is 25 ℃-30 ℃ in daytime, more than 32 ℃, which is disadvantageous to growth and flower bud differentiation. 18 ℃-20 ℃ at night, not less than 15 ℃. If the temperature is kept high all the time, it is beneficial to its flowering.

Second, humidity: Phalaenopsis likes higher air humidity and should be kept at 70% MUR 80% during growth. Therefore, water should be often sprayed into the surrounding space to increase humidity, but the moisture of the matrix should not be too large, otherwise it is easy to rot the root. The dry substrate is conducive to the growth of new roots.

Third, lighting: open the shade net in time according to the weather conditions every day to promote the photosynthesis of Phalaenopsis, and open the skylight to make it ventilated when the temperature or humidity is too high.

Fourth, fertilization: fertilization should adhere to the principle of "frequent application of thin fertilizer". 1500 times compound fertilizer and 5000 times boric acid can be sprayed, and then 1500 times compound fertilizer can be applied every other week. In addition, Phalaenopsis is a fleshy root, in order to make its root system thick, the application of potash fertilizer is more important.

Fifth, pest control: in order to prevent the occurrence of diseases and insect pests, disinfect the greenhouse before entering the seedling, usually spray fungicides regularly, usually once a week, and choose sunny days as far as possible when spraying.
