In winter, some farmers lay a thin layer of film on a trampoline. Although the temperature of the trampoline is 8~10°C higher than the maximum temperature in sunny days, when the temperature is very low in the early morning, the trampoline is only 1~2°C higher than the outside world. If you use the following two methods, it can play an ideal warming and warming effect.
One, double membrane grass curtain. That is, a double layer of film is used to sandwich a straw curtain. This method is simple, does not require much investment, has good warming and warming effect, and can be 6°C warmer than the temperature of a layer of film, and can play a role in cooling regulation in March. At this time, the temperature of the trampoline is more than a flat film. To lower the temperature by 6°C, avoid overheating.
Second, bamboo frame plastic shed. Using bamboo frame plastic sheds, less investment, good results, an average daily temperature of 10 °C, calculated according to the low temperature period of 150 days, the cumulative increase in temperature 1500 °C, equal to the average temperature of 20 °C 75 days accumulated temperature, in other words, this is equal to Farming more than 2 months of growth, so that the quail grow fast, early spawning, laying a good foundation for high-yield throughout the year. In the plastic shed, the north and west sides of the plastic shed must be draped with straw drapes, and a straw cage must be placed in the middle of the trampoline for ventilation, and then covered with a thin film. In low-temperature areas, two layers of film can be covered with a layer of straw curtains.
