The substrate of rose soilless cultivation is composed of perlite and granite millet. The thickness of the substrate is about 30 cm, the lower part is millet, and the upper part is filled with perlite and millet alternately. The pH is between six and seven.
Samonsa, a Dutch variety, is chosen for soilless rose cultivation. Because of its beautiful shape, high yield and good quality, it is widely welcomed.
In order to cool down in summer, sunshade cloth is usually covered on the top of the shed, and water is often sprayed in the shed. In winter, in order to keep warm, plastic film and gauze will be sealed around the shed, so as to increase the temperature and promote the growth.
The most suitable nutrient solution formula for Rose soilless cultivation is 53 ppm sodium, 51 ppm phosphorus, 378 ppm potassium, 162 ppm calcium, 34 ppm magnesium, with a pH of 5.5-6.5 and a total concentration of 0.23%.
Rose soilless cultivation requires the construction of two nutrient pools, one containing calcium nitrate and the other containing other elements. Both are built outside the shed with the same volume and open at the same time.
In the early stage of growth, less application, once a day or longer, to the production period, increase the liquid supply, once a day when the sun is sufficient, rainy days can be appropriately reduced
In summer, spray water less frequently, avoid diluting nutrient solution, in winter, when the temperature rises to 30 degrees, spray water, or you don't need
