During the dormancy period, trimming is also performed. The pruning time is around the Spring Festival, and the main branches are cut off from the base of the big rose more than 2 years old, dead branches, weak branches and overlapping branches, and cross branches. In addition, pruning is performed in different degrees according to the varieties and characteristics of the Chinese rose and the growth conditions. Only 2-3 main branches are reserved for the plants with poor growth potential, and 2/3 of the main branches can be cut; for normal growth, the plant type is well-established and frequently flowered. The species can be cut to about 1/2; for plants that are robust and have frequent flowering, only 1/3 of the crop is cut off. The anti-corrosion film is applied to the wounds caused by trimming to promote the healing of wounds as soon as possible so as to prevent the invasion of pests.
Soil Sterilization: Soil is the main medium for transmission of pests and diseases, and is also the main site for the propagation of pests and diseases.

Strengthen facilities management: regularly inspect the isolation measures of greenhouses and control the invasion of pests; greenhouses must have adequate ventilation and dehumidification capacity; reasonable irrigation system to avoid wetting the plants; timely cleaning of the greenhouse film, timely ventilation and ventilation with temperature changes and Dehumidify.
Chemical control: Use chemical pesticides to control the use of fumigation (sulfur fumigation, smoke fumigation) as much as possible, and use pesticides that do not easily leave stains when using spray methods.
