(a) lighting

Improve the lighting conditions in the shed, mainly by improving lighting conditions and artificial fill light. Under the premise of favorable heat preservation, the cold cover should be uncovered as early as possible to extend the time of receiving light. This is especially important for positive and long-day flowers such as rose, carnation, gypsophila, and gladiolus.

Flowers must be cultivated in a good growing environment, so its ambient temperature is important. The temperature of day and night in the open field is relatively large, and the temperature difference in the greenhouse is small, which is the difference between them.

The temperature control of the greenhouse(Non Woven Polypropylene Roll On Sales) is mainly carried out by ventilation and heating. In order to minimize heat loss and increase temperature and soil temperature in winter, the plastic film in the greenhouse should be as tight as possible. The shed is covered with a non-woven fabric, and the geothermal line is used to raise the temperature of the soil, and the coal burning furnace increases the temperature inside the shed.
