Doing a good job in pig farm greening has great effect and significance on improving the microclimate of pig farms. It can purify about 25% to 40% of harmful gases and adsorb about 50% of dust. It can also reduce noise, prevent epidemic isolation and prevent heatstroke. There are a number of trees in and around the fence of the farm according to the site conditions. It is better for the conditional farms to plant 5 to 10 meters wide isolated forest belts outside the site. It is generally required that roadside trees be planted on both sides of the road in the farm, and fast-growing, tall deciduous trees (such as metasequoia, poplar, etc.) should be planted between each building. The greening and planting of the trees in the field should take into account the height of the trunk and the size of the canopy, and should be protected from wind and cold in the hot days. All kinds of vegetables, flowers, and shrubs are used in the idle areas of the farm. What are the basic requirements for building pigs? What are the architectural forms? (1) An ideal pig house should meet the following requirements 1 The pig house is required to be cool in winter and cool in summer, capable of keeping warm and insulating, so that the temperature in the house can be kept constant; 2 to have good ventilation facilities to keep the air in the house clean; 3 Have a suitable sewerage system to facilitate the training and cleaning of herds; 4 must have strict disinfection measures and disinfection facilities; 5 Have good drinking water facilities and facilities for warming drinking water in winter; 6 It is necessary to have a suitable cooling system to maintain the temperature in the summer housing in a suitable range. 7 It is easy to implement scientific feeding and management. When building a pig house, full consideration should be given to complying with the pig production process, so that it is easy to operate, reduce the intensity of labor production, increase the management quota, and fully provide labor safety and labor protection conditions. (2) The architectural form can be divided into open, semi-open, and closed type according to the wall structure and windows. 1 The open-style pig house has walls on three sides, one side without walls, good ventilation and lighting, simple structure and low construction cost, but it is hard to solve the cold in winter due to large influence from outside. 2 Semi-open pig houses have three walls on one side and a half wall on one side. The insulation performance is slightly better than that of the open type. If the straw or nail plastic sheet is hung over the half wall in the winter, the insulation performance can be significantly improved. 3 Closed pig houses can be divided into windowed and windowless types. There are window-type pig houses: walls are set on all sides, and windows are set on the vertical wall. The size, number and structure of the windows are determined according to local climatic conditions. In cold regions, the south window of the pig house should be large, and the north window should be small to facilitate insulation. In order to solve the problem of effective ventilation in summer, hot summer areas can also be provided with windows on the two vertical walls, or wind pipes and vent roofs on the roof. Window-type pig houses have better thermal insulation performance, and according to different seasons, they can open and close sashes to adjust ventilation and insulation. Windowless pig houses: High degree of isolation from the outside environment, with only emergency windows on the wall, only for power failure emergency use, not for lighting and ventilation, ventilation, light, and temperature in the building are controlled by artificial equipment. It is able to provide pigs with suitable environmental conditions, which is conducive to the growth and development of pigs and increase productivity. However, this type of pig house has large civil engineering and equipment investment, high equipment maintenance cost, and it can still regulate ventilation when the outside climate is good. And the lighting, high energy consumption, the use of such pigs for more demanding environmental conditions of the pig, such as sow maternity, pig breeding room.
