Control methods for greenhouse pests and diseases in winter
First, use resistant varieties
The selection of disease-resistant varieties is an important approach to disease prevention and control. It is necessary to consider the high yield and high quality characteristics of the varieties, pay attention to the collocation of the varieties when planting, and rationally arrange them so as to avoid the long-term contiguous planting of a single variety.
Second, strengthen field management
Deeply turn over the land, increase organic fertilizer, implement crop rotation, remove diseased plants in the greenhouse, strengthen water and fertilizer management, and apply foliar fertilizers to increase plant resistance.
Third, ecological control
By using a closed greenhouse environment, environmental conditions conducive to crop growth and unfavorable to disease growth are formed to prevent disease. The first is to control the humidity, greenhouse vegetable cultivation should be ridge film, irrigation should be done under the film dark irrigation, it is best to use drip irrigation or infiltration, cover rice straw and other measures to control humidity; followed by warming and humidity, early morning Relieve the curtain, until the room temperature rises to 28°C, open the ventilation vents, and increase the ventilation in the afternoon. The room temperature is controlled at about 20°C. From January to February, it is necessary to grasp the time for opening and closing curtains and pay attention to the insulation.
Fourth, physical control
Soaking in warm soup kills the surface of the seed and the inside of the seed latent pathogens; deep-cultivation sunburn, to prevent soil-borne diseases; the use of greenhouse yellowfly, aphids, yellow spotted insects such as Liriomyza sativa, set yellow trap.
V. Chemical Control
Rational use of medicine should be done, and appropriate early prevention. At the same time, we must actively develop and promote biological pesticides, high-efficiency, low-toxicity and low-residue pesticides, dust agents and aerosols, and organically combine soil disinfection, seed treatment, pesticide spraying, dusting, and smoking to prevent and control pests and diseases.
