How to raise ornamental fish to heat the farm

In the process of artificial cultivation of Eupolyphaga Seu Steleophaga, heating cultivation is extremely important. Because warm cultivation can break the hibernation habit of Eupolyphaga sinensis, it can shorten the growth cycle of Eupolyphaga sinensis by 2/3, which is in line with people's psychology of getting rich quickly. Although heating increases the cost of aquaculture, it is insignificant compared with the economic benefits obtained. Because the three-dimensional rearing of Eupolyphaga Seu Steleophaga is shallow underground, in cold winter months, Eupolyphaga Seu Steleophaga often freezes to death because it can't stand the surrounding cold, so it is more necessary to heat it when raising it on a large scale. Doing a good job in heating is an important link to improve economic benefits.

The following are several heating methods:

(1) Electric heating mode is easy to operate and manage with electric furnace or heater. In order to maintain a certain humidity, it is best to use a humidifying heater. You can put a aluminum pot boiling water on the electric stove to increase the humidity. The advantage of using electricity is no pollution, but the cost is higher. Generally used for larval rearing or egg hatching. (2) Coal stove heating mode When ordinary coal stoves are used for heating, iron chimneys should be installed to discharge the oil fume outdoors. Because the iron plate dissipates heat quickly, it can quickly increase the indoor temperature, and it is economical and easy to operate. The disadvantage is that coal consumes indoor oxygen when burning, which is easy to cause indoor hypoxia. So pay attention to supplement oxygen. One of the ways to increase oxygen is to open doors and windows several times a day, or to use the characteristics of plants to "suck carbon and spit oxygen" and plant flowers indoors to increase oxygen. (3) Fireway heating method: Fireway heating is used in the feeding room, and the fuel can be coal or firewood. The fire channel can be designed as straight tube, U-shaped or S-shaped to achieve maximum heat dissipation. The fire path is generally located on the flat ground, and the heat source rises slowly from bottom to top. Even if the stove goes out for several hours, there is still residual heat in the fire channel. In order to prevent gas poisoning, the combustion furnace is generally located outdoors. If you are indoors, you should pay attention to ventilation, as shown in the color map 17. (4) Steam pipeline heating method Large-scale professional farms with conditions can use boilers to burn steam and send it to the feeding room for heating. This is a one-time investment for many years. The hot water from the boiler can be used for brewing feed, scalding insects, bathing and so on. A switch is added in the feeding room to control the temperature. This heating method is safe and can achieve ideal heating and humidification effect. The disadvantage is that the cost is high and it is not suitable for small-scale farmers.
