The use of a thermostat to control the temperature and ventilation of the house and to achieve minimum ventilation management can not only allow the temperature of the house to meet the chicken's normal growth and development needs, but also save coal and reduce the cold wind on the chicken body.

Install air duct

On each side of the chicken house, an air duct with a diameter of 16 to 18 centimeters and a length of 3.5 to 4 meters is installed at every 4 meters along the roof of the house, installed along the ceiling, and made of lightweight materials such as plastics, polyvinyl chloride and fiberglass. Can help to minimize the ventilation control and reduce the chicken's stress response.

Heating stove heater

Among all the heating methods, the heat efficiency of the warm air heater is the highest, and the temperature rise is fast, which can meet the need of the chicken house temperature to the maximum. The temperature difference between the exhaust gas discharged from the winter house and the supplemented fresh air is relatively large, and the residual heat of the exhaust gas has a certain utilization value. Therefore, in order to solve the contradiction between ventilation and ventilation, it is possible to use the waste heat heater in the exhaust gas to reduce the energy waste and improve the breeding efficiency.

Promotion of flues

If furnace heating is used, the length of the cycle of the chimney in the house should be extended as much as possible so that the heat generated by the coal combustion can be distributed in the chicken house as much as possible to reduce the waste of heat energy and the smoke outlet should not touch the heat. The length of a typical chimney is about 20 meters.

Build insulation shed

At present, some farmers have built a plastic film insulation shed on the front and back walls of the chicken house, using solar energy to supply heat, which not only absorbs the heat of the sun, but also reduces the heat loss of the chicken house, and can save energy by about 1/3. At the same time, avoid cold wind blowing directly into the house causing cold stress.

Other insulation measures

Block the window. If there are conditions, you can use plastic steel, aluminum alloy doors and windows, double glass thickening specifications, although the cost is high, but eliminating the cumbersome annual block. Poor conditions can be achieved by using polystyrene board, cotton curtains and multi-layer plastic methods to seal the windows, and then use wood or cardboard to reinforce and nail the inner thermal insulation material to avoid cold wind directly entering the chicken house. The insulation effect.

House ceilings. For a house with a high ceiling or a poor roof insulation effect, a ceiling can be hung in the house, or a layer of insulating cotton felt or straw (straw, wheat straw, etc.) can be laid on the roof to improve the insulation effect and reduce heat loss.

Increase wall thickness. In order to reduce the heat loss and maintain the indoor temperature, a layer of polystyrene board can be applied inside or outside the wall. The thickness of the board can be flexibly controlled according to the thickness of the wall. If it is done well, this measure can save energy 1/4.

Set ground or underground flue. If the house is provided with ground or underground flue gas for heating, a certain amount of fuel should be added, and at the same time, attention should be paid to preventing flue gas leakage. The above-ground flue gas is hotter than the underground flue gas, and the utilization rate is high. The underground flue gas can save space compared with the flue gas above ground.

Greenhouse Flat Hydroponics

Greenhouse Flat Hydroponic System is increasing in popularity among commercial and hobby growers, and with good reason. With the right setup, hydroponic growing system is a cost-effective method to grow high-quality produce with maximum yields.

Greenhouse Flat Hydroponic System is perfect for for start-up commercial growers. Using the nutrient film technique (NFT), the System sustains hydroponic agriculture at improved rates and is ideal for growing: basil, cilantro, parsley, arugula, watercress, fancy lettuce, head lettuce, bok choy, mizuna, kale, chard, and more.
