Qingyuan vegetable farmers should strengthen the prevention and treatment of diseases in the late stage of vegetable growth, directly reduce the number of pathogenic bacteria, and after the harvest of each stubble vegetable, thoroughly remove the residual branches and leaves of the field. For vegetables that are susceptible to root diseases, the residual roots should be removed. The purpose of deep ploughing is to destroy the living environment of the germs. Generally, it is required to plough 40 cm deep after each harvest. With the help of natural conditions, such as low temperature and ultraviolet rays, some of the germs are killed. Disinfection During the summer vegetable stubble gap, after deep ploughing, irrigate enough water, cover with plastic film for high temperature disinfection, so that the maximum temperature of the soil layer 10 cm reaches 70 ℃, can kill a large number of germs, this is a simple and effective prevention and control method. Reasonable rotation rotation can not only improve the stress resistance of the crop itself, but also make the pathogens hidden in the ground reduce or lose the infection ability after a certain period of time. There are two types of vegetable rotation: one is the rotation between vegetables and vegetables, and it is required to determine the interval between the cultivation of similar vegetables according to the survival time of the pathogens in the soil; the other is the rotation between vegetables and food crops.

Hydroponics can be used to make the most use of the interior space. The relatively closed environment of a greenhouse has its own unique management requirements, compared with outdoor production. Pests and diseases, and extremes of heat and humidity, have to be controlled, and irrigation is necessary to provide water. Most greenhouses use sprinklers or drip lines. Significant inputs of heat and light may be required, particularly with winter production of warm-weather vegetables.
