In winter, the temperature keeps dropping, and hazy weather occurs from time to time. Haze and haze weather will adversely affect the vegetable production in greenhouses. Low temperature, high humidity, and low light will cause poor growth and development of vegetables in greenhouses, and the diseases will be aggravated, which will reduce the yield and quality. The farmers should promptly take preventive measures. Agricultural gas experts support agricultural farmers to improve the microclimate environment in greenhouses through warming and supplementing light, and reduce the probability of disease occurrence by reducing the humidity in the greenhouse, scientific fertilization and other management measures.
In humid days, the humidity of the air is high, and the moisture in the leaves is not easy to evaporate, resulting in water absorption in the roots. At this time, the fertilizer elements transported by the moisture to the leaves do not go up. This will easily lead to the lack of nutrients in the roots and leaves. It is prone to yellowing of leaves or yellowing on the sides of leaves.
Appropriate nutritional supplements to crops are also critical. Frequent haze and haze can easily cause the color of the leaves not to be green and not to thrive, which is a manifestation of lack of nutrition. Due to the relatively low temperature, the roots of the fertilizer in the soil are not easily absorbed. We can properly use the warming agent for the greenhouses in response to this problem. Jinbao greenhouse warming agent is the use of the function of microbial decomposition of fermentation, the straw into the crop's organic and inorganic nutrients, temperature, heat, carbon dioxide, and produce related biological disease prevention and disease resistance, and ultimately obtain high yield, high quality, no A new bioengineering technology product for public agricultural products. It is fundamentally different from traditional crop cultivation techniques. It is the latest technology for straw harmless, resource-based, on-site use, and cyclic conversion. It saves water and electricity, saves labor, saves money, and greatly reduces costs while increasing production and Quality, increase production, increase economic efficiency.
In the wintertime, often accompanied by hazy weather, the following points should be noted when planting greenhouse vegetables:
1. Insulation temperature. Increase the number of outer layers of grass curtains and films to increase the insulation effect; buckle small sheds in the shed, cover the film and straw curtains at night to improve the insulation properties; lay the film to increase the temperature; and use the warming agent of Ginpa greenhouses to improve the shed. The temperature is simpler, more convenient and more effective.
2. For light. Keep the film clean, timely wipe the dust on the film with a rag to ensure the transparency of the film. When the temperature dropped within the range of 1~2°C after the curtain was exposed, the vegetables could be properly exposed to light. Reflected light can also be used to increase light, such as laying a reflective film on the ground, or painting a white wall.
3. Scientific fertilization. It is necessary to reduce the application of fertilizers, especially nitrogen fertilizers, increase the application of phosphorus and potassium fertilizers, microbial fertilizers, and decomposed organic fertilizers in order to reduce the emission of harmful gases and improve the cold resistance of vegetables.
4. Prevent disease. Strengthen the monitoring of disease, spray protection in advance with disease-preventing agents, and prevent the occurrence of the disease in advance. Special attention should be paid to the occurrence and spread of gray mold and downy mildew. Once the disease occurs, it should be promptly treated.
