Is the temperature of the water curtain in the henhouse as low as possible?

With the approach of summer, the temperature is getting higher and higher, and it is impossible to reach the suitable temperature for broiler growth only by cooling down with fans. It is especially important to use wet curtains to cool down. How to make good use of wet curtain to keep chickens from catching a cold?

0 1, when the temperature in the henhouse is higher than the set temperature 1-4 degrees Celsius, consider strengthening ventilation and using air cooling effect to cool down; When the temperature in the chicken coop is above 5 degrees Celsius, we can consider using Guangdong Energy Wet Curtain to cool down.

02, we first understand a problem: opening the wet curtain is not only to cool down, but to control the temperature in the henhouse within a relatively reasonable temperature range.

Under normal circumstances, after the wet curtain is opened, the temperature keeps fluctuating within the range of 65438 0 degrees Celsius. For example, the temperature of opening the wet curtain today is 30 degrees Celsius. After opening the wet curtain, keep the temperature at 29-30 degrees Celsius, and don't cool it too much at once. In a short time, if the temperature difference exceeds 5 degrees Celsius, chickens may catch a cold.

03, open the wet curtain, ranging from small to large, first use the two side walls, and finally use the gable wet curtain, and finally install the air curtain in the henhouse to reduce the cross-sectional area of the henhouse and increase the wind speed.

04, open the temperature of the wet curtain, in normal climate, every day to reduce 0.3-0.5 degrees Celsius, when the temperature of the open wet curtain reaches 26 degrees Celsius, there is no need to drop again.

05. After opening the wet curtain, be sure to avoid cold air blowing directly on the chicken.

In farms with wet curtain boards, the inclination of wet curtain boards can be used to guide the wind direction; In farms without wet curtains, plastic paper or plastic bags can be used to guide the wind.

06. After opening the wet curtain, pay attention to the temperature difference at both ends of the henhouse to be controlled within 2 degrees Celsius. Reasonable use of the number of fans to control temperature difference. If four fans can control the temperature difference, do not turn on five fans; If five fans can control the temperature difference, don't turn on six fans to minimize the impact of air cooling on chickens.

07, after opening the wet curtain, to grasp the wet curtain switch time.

After opening the wet curtain, be sure to grasp the opening and closing time of the wet curtain. It can be turned on for 3 seconds without turning on for 5 seconds 10 minutes without stopping for 8 minutes.

Intermittent opening of water curtain: The closing time of water curtain pump is more important than the opening time. When the water curtain paper is completely dried, start the water pump to supply water, and keep the water curtain in the cycle of gradual drying and gradual wetting, so as to achieve the best effect of water vapor evaporation on the surface of the water curtain paper.

Chickens under the age of 08.25 days can adopt mixed ventilation (wind window, gate and wet curtain are opened at the same time); For older chickens, after opening the wet curtain, it is necessary to check whether the small air inlet window is tightly closed, so as to prevent the death of hot chickens due to the untidy closing of the small window.

09. After opening the wet curtain, check whether there is any ventilation dead angle in the henhouse. If there is, you should drive the chickens out there.

10, pay attention to the external humidity when opening the wet curtain.

When the external humidity is lower than 50%, try to avoid opening the wet curtain, because the temperature will drop greatly after opening the wet curtain at this time; When the outside humidity exceeds 80%, it is what we call sauna weather. At this time, the cooling of the wet curtain is not obvious. At this time, you must try to turn on the fan and use the air cooling effect to cool down.
