In the process of planting greenhouse vegetables, one or more kinds of vegetables are planted in the greenhouse. In order to ensure the growth of vegetables, agricultural control measures are needed. Because of the different varieties of vegetables in greenhouse cultivation, different preventions and treatments are needed. Measures. Farmers need to take effective agricultural control measures according to the specific conditions of their own greenhouses, timely clean up the debris in the greenhouse, and do temperature control work. During the cultivation of greenhouse vegetables, most of the occurrence of pests and diseases has a relationship with greenhouse temperature, so it is necessary to adjust the greenhouse temperature appropriately. (Photo from Oriental IC) In greenhouse vegetable cultivation, physical control methods can be used to control pests and diseases. There are many ways to use physical control, such as color paper trapping or insecticidal lamp trapping. Physical control is harmless, and it also has an ideal control effect on cabbage caterpillars. In the prevention and control of insect pests in greenhouse vegetables, biological control methods can be adopted to establish a bio-symbiosis system, using natural enemies of pests to control pests, and maintaining the ecological balance in the greenhouses to achieve effective prevention and control of pests and diseases. Drug control is a method often used in the prevention and control of pests and diseases. Because of the long-term cultivation of crops, the soil immunity is reduced. Therefore, in the greenhouse vegetable cultivation, the deterioration of pests and diseases often occurs, and the scope of pests and diseases should be sprayed in time. Drug treatment, thus ensuring the quality of vegetables in greenhouses. Based on the particularity of greenhouse vegetable cultivation, it is necessary to start from the actual situation in the practice process, do a good job in the prevention and control of pests and diseases, and ensure the effectiveness of prevention and control measures. In addition, due to the variety of planting techniques, different technical forms have different effects on vegetable cultivation. Therefore, in the process of practice, it is necessary to understand the characteristics of the technology and meet the overall requirements of the planting form. It is necessary to constantly improve planting techniques, do a good job in the prevention and control of pests and diseases, and ensure the safety of vegetables.
