Matrix
The substrate of the rose without soil cultivation is composed of perlite and granite small stone rice. The substrate is about thirty centimeters thick. The lower part is small stone rice, and the upper perlite and small stone rice are filled alternately. The pH value is between six and seven.
Variety
Rose flowers have no soil cultivation varieties. The Dutch varieties are the Dutch species Simonha. Because of its beautiful form, high yield, and good quality, they are popular.
Summer and wintering measures
In the summer, in order to cool down, the shading cloth is usually covered on the top of the greenhouse, and water is often sprayed in the shed. In the winter, plastic films and gauze nets are generally sealed around the greenhouse for thermal insulation, so as to increase temperature and promote growth.
Nutritional management
Formula of Nutrition
The most suitable nutritional liquid formula for roses without soil cultivation is: sodium 53PPM, phosphorus 51PPM, potassium 378ppm, calcium 162ppm, magnesium 34ppm, and the pH of 5.5-6.5, with a total concentration of 0.23 percentage.
Construction of Nutrition Pond
Two nutritional pools need to be built without soil cultivation of roses, one is calcium nitrate, and the other contains other elements. Both are built outside the shed and the volume is the same and open at the same time.
Application of nutrient solution
In the early stages of growth, it is applied less or more every other day. When the production period is increased, the amount of liquid supply is increased. When the sun is sufficient once a day, the rainy weather can be appropriately reduced.
Water management
Spray less water in summer to avoid dilute nutrients. In winter, the temperature rises to thirty degrees and one goes.
