Foggy weather facilities agriculture to pay close attention to warming up light
2023-04-08 01:07:27
Since the beginning of winter this year, there have been many occurrences of haze in many northern regions of China. Overly heavy haze not only seriously affects the respiration of plants, but also obstructs the sun and impedes the photosynthesis of plants, which has a particularly serious impact on facility agriculture. . In view of the harm of haze to agricultural production, it is urgent to take effective measures to prevent and control it. Recently, this reporter interviewed agricultural experts on this issue in particular to discuss issues such as how to manage fog and haze weather facilities and hope to provide guidance for scientific production of readers.
Since the beginning of this year, a large number of haze-locked weather has appeared in many places in China, and the air quality has been heavily polluted. In recent days, Xi'an, Shaanxi Province has seen the appearance of PM2.5 explosions. The air quality is worrying and it also has an impact on the planting industry. In an interview on December 20, Li Jianming, a professor at the College of Horticulture, Northwest Agriculture and Forestry University, told reporters that the Ministry of Agriculture is seeking relevant opinions in response to the severe hazy weather that has occurred in many places across the country. They are recommending that the haze hazard be carried out as soon as possible. Related research.
Smoggy weather is not conducive to plant growth
Talking about the impact of haze weather on planting industry, Li Jianming told reporters that under the circumstance that human health is greatly threatened, the impact of haze weather on plant growth is undoubted. He said: "Smog and haze weather affects the photosynthesis of plants and affects the plant's metabolic system. This is the obvious effect of hazy weather on the growth of crops." As for the specific field crops, Li Jianming frankly stated that it has not yet been carried out. Systematic research on the aspect, so for the time being it can not be determined in what aspects of these effects, but even so, it is an indisputable fact that plant growth is affected by haze weather.
Facility agriculture anti-fog and haze need to do warming insulation in the shed
Li Jianming pointed out that the impact of hazy weather on facility agriculture is very direct, which is that the light in the shed is weakened and the temperature is reduced. In this regard, Zhang Baojun, a director of the Agricultural Industrialization Branch of the China Agricultural Association and a professor at the Agriculture College of Northwest Agriculture and Forestry University, believes that it is critical to warm up greenhouses in time for haze.
So, how to achieve warming insulation in the greenhouse? Professor Zou Zhirong of the Northwest A&F University gave advice to farmers engaged in planting agricultural facilities: He said that under low temperature conditions, thickening grass curtains on the greenhouse and carrying out multi-layer covering is the most common method for warming insulation of greenhouses. In addition to this, cautious irrigation is also particularly important. Zou Zhirong reminds the growers that the low temperature of the fog should not be used to irrigate crops, because irrigation will cause the soil temperature to decrease, which is extremely unfavorable for the growth of crops; in addition, he said that When the temperature in the shed is lower than 8°C, consider adopting the method of smoke-curing, setting up the cold-proof ditch and other methods to timely make up the temperature for the greenhouse, and provide suitable growth temperature for the crops inside the shed.
Fog and haze need to pay more attention to fill light in the shed
Talking about how to make up for the facilities agriculture in continuous haze weather, Zhang Baojun believes that the most economical and feasible way is to unveil the grass curtains at a proper time to maintain the cleanliness of the shed film and fight for the growth of crops when the temperature is not very low. To the light. Li Jianming told reporters that at this stage, there are conditions for supplementing crops in modern factory-built greenhouses. The most common method is to install some light sources to allow crops to have sufficient light for photosynthesis and ensure their normal growth. Such light sources include bio-sodium lamps, LED lights, and the like. "Timely light supplements are necessary for crops, so all growers should pay more attention," Li Jianming said.
