The negative impact of haze on facility agriculture runs through the entire process of growing crops, so it is critical to be well prepared. At this time, farmers should adjust some related facilities in time to timely control the temperature, light, and humidity that the plant should have, so that the growth environment of the plants is basically stable.
The temperature can be controlled outside the greenhouse to lay grass braid or increase the thickness of the plastic film, in the greenhouse and then set a small arch shed, at night can also be covered in a small arch shed on the film or grass, double to enhance the warm effect. It is also possible to lay a mulch to increase the surface temperature, reduce the humidity in the shed, and enhance the plant's ability to withstand pests and diseases. Automated greenhouses can also be constructed where conditions permit, and the temperature of the room can be controlled by automatically adjusting the electric heating plate, the temperature-increasing combustion block, and the hot blast stove according to the weather.
When the light and fog are enhanced, an incandescent lamp can be placed in the shed to allow the crop to have sufficient light for photosynthesis. At the same time, the yellow leaves of the crops should be cleared in time to avoid blind spots. It is also possible to use warming and fattening combustion blocks, bath heater heating lamps, plant growing lights, and other economical and effective means to warm up.
In order to manage the fertilization of water and fertilizers, the application of organic fertilizers and phosphorus and potassium fertilizers should be increased, the input of nitrogen fertilizers should be controlled, the cold resistance of crops should be improved, and the emission of harmful gases should be reduced. In terms of irrigation, the crops in the initial stage of growth should be watered on time in order to ensure the necessary water for plant growth. Ventilate immediately after watering, avoiding too much humidity and invading diseases and insect pests. Membrane or soil cover can be used to regulate evaporation of deep soil moisture.
During the prevention and control of pests and diseases, we should manage the health in the greenhouses, remove waste stems, water and weeds from the waste crops in a timely manner, and also use equipment such as insect nets and black light lamps. Once onset, timely treatment with aerosols or dry powders, on the one hand to control the condition, on the one hand to reduce the humidity, but the ventilation should be timely ventilation after 8 hours.
