Winter greenhouse insulation method of winter vegetables, greenhouse cultivation to a certain extent affected by the temperature, how to give greenhouse insulation in the winter? The heat preservation of greenhouses has always been a key problem for growers, especially in the northern regions of China, and even affected the healthy development of the vegetable industry. In response to this problem, agricultural experts and the majority of growers have thought of many methods, such as multi-layer insulation, heating by lamps, heating by heating lines, and heating by hot air ovens. Although it achieved certain results, it also exposed many of its shortcomings and deficiencies.
The simple method is "natural" heating. The so-called natural heating is not just an increase in temperature for no apparent reason, but due to the hard work of the unsung hero, this hero is a greenhouse warmer. The specific method is: in the preparation of soil preparation, sorghum or seedbed, fill the soil with cow dung, pig dung, fresh garbage, smashed fertilizer and crushed straw, straw, and then add the right amount of greenhouse warming agent, and finally landfill garden soil, Microorganisms in greenhouse warmers can work with raw materials. These raw materials can slowly release the heat and gradually increase the temperature of the soil and air to ensure the normal growth of the plant. Experiments have shown that this method has good results in the early cultivation of fruit vegetables in winter and the early cultivation of leafy vegetables such as leeks and leeks.
