Substrate
The substrate for soilless cultivation of roses is composed of perlite and granite pebbles. The substrate is about thirty centimeters thick, with the lower part made of pebbles and the upper part made of pebbles. Filled alternately with perlite and pebbles. The ph value is between six and seven.
Variety
The Dutch variety Sammonsa is chosen for soilless cultivation of roses. It is very popular because of its beautiful shape, high yield and good quality.
Summer and wintering measures
In order to cool down in the summer, the top of the greenhouse is usually covered with a shade cloth, and water is often sprayed inside the greenhouse. In winter, in order to keep the greenhouse warm, plastic film and gauze are usually sealed around the greenhouse to increase the temperature and promote growth.
Nutrient solution management
Nutrient solution The formula
The most suitable nutrient solution formula for soilless cultivation of roses is sodium 53ppm, phosphorus 51ppm, potassium 378ppm, calcium 162ppm, magnesium 34ppm, the pH is between 5.5-6.5, and the total concentration is 100 ppm. 0.23 points.
Construction of nutrient pools
Soilless cultivation of roses requires the construction of two nutrient pools, one containing calcium nitrate and the other containing other elements. Both are built outside the shed. Same, open at the same time.
Application of nutrient solution
In In the early growth stage, apply less, once every other day or more. When the production period comes, increase the amount of liquid supply, once a day when there is sufficient sunshine, and reduce it appropriately in rainy weather.
Water management
Spray water frequently and sparingly in summer to avoid diluting the nutrient solution. In winter, water should be sprayed after the temperature rises to 30 degrees or above, otherwise there is no need .
