1. Heatstroke prevention and cooling The heatstroke of goose houses must be taken from various aspects such as improving the feeding and management, the heat insulation design of the envelope structure, and the heat prevention design of the goose house structure. If you still cannot meet the requirements, you must also consider cooling.
(1) Thermal insulation design of enclosure structure First, the thermal insulation index of the enclosure structure should be determined. Generally, there are summer low thermal resistance, total low limit attenuation, and total delay time. Then based on the calculated values ​​of these indicators, the building materials and required thicknesses for the heat insulation layer of the summer enclosure structure are determined.
(2) Other construction design heatstroke prevention measures 1 Design and build ventilation roofs;
2 The outer surface of the envelope structure is treated as a light-colored and smooth structure;
3 Planting tall trees and climbing plants for shade;
4 Select Campanile-style, Semi-Bellbell-style roofs, or ventilated ridges.
5 Design goose houses with large windows or sheds for ventilation.
(3) Properly reduce stocking density, improve feed formulation design, etc.
(4) The cooling of a goose house generally uses the evaporation of water to absorb the heat in the air to achieve the purpose of cooling or preventing heatstroke. Commonly used methods and equipment include a wet pad, ventilation, spray, and spray. No matter what kind of cooling method is used, it needs to consume energy, so it also involves the problem of investment and return. It must be carefully selected and carefully calculated.
(2) Preventing the cold of the cold-proof heating goose house must also take measures from various aspects such as improving the feeding and management, the thermal insulation design of the envelope structure, and the cold-proof measures of other buildings. When still not meeting the requirements, consider heating again.
(1) Thermal insulation design of enclosure structure First, the thermal insulation index of the enclosure structure should be determined, and the lower limit thermal resistance in winter is generally used. Then based on the calculated value of this indicator, the building materials and required thicknesses for the insulation layer of the winter enclosure structure are determined.
(2) Other architectural design measures for cold protection 1 Select windowless or closed dormitories without windows;
2 Due to the small height of the winter sun, the direction should be 15 degrees to 30 degrees east or south to the south or south. The south vertical wall can receive more solar radiant heat, and can make the vertical wall and the main winter wind direction ( China's northwest or northerly wind generally forms an angle of 0 to 45 degrees to reduce cold wind infiltration;
3 The height of the goose house should be reduced to reduce the outer wall area when allowed; in addition, the same area and height of the goose house, the increase of the span can also reduce the length and area of ​​the outer wall, so it is beneficial to remain in the cold insulation;
(4) The northern wall is windward in winter, and the cold wind of the northern wall is more infiltration. After determining the total area required for the window, the north window area should be reduced. The area ratio between the north and south windows can be 2:1 to 3:1; At the same time, the northern wall and the western wall should not have doors as far as possible;
5 Set up windbreak forests in the west and north of the site.
(3) The heating of the goose house should first realize that no matter which heating method is used, it needs to consume energy, so it must also be carefully selected and carefully calculated. Generally, the total calorie loss of the goose house in winter should be calculated first (the basic caloric loss of each part of the enclosure structure plus various additional loss of calories). If the total output heat of the goose group is less than the total calorie loss, heating is required. The heating provided by the geese includes local heating such as infrared lamps or infrared heat preservation umbrellas commonly used for brooding, as well as heating of flue gas, heating of hot water, and heating of hot stoves. Flue gas heating is only suitable for farmers and small fields, and experienced bricklayers can build stoves and flues. Hot water heating and hot air stove heating need to be designed by professionals.
Agricultural Chemicals refer to the inputs in agricultural production such as fertilizers, pesticides, veterinary drugs and growth regulators, their use can promote the production of edible agricultural products, in the sustained and rapid development of agriculture plays an important role. Agrochemicals can be divided into 3 categories: chemical fertilizer, pesticide and agricultural film.
1. Chemical fertilizer is the abbreviation of chemical fertilizer. It refers to the fertilizer made by chemical and/or physical methods containing one or more nutrient elements needed for the growth of crops. It is mainly used to improve soil fertility and increase the yield of crops per unit area. Nitrogen fertilizer, phosphate fertilizer and potash fertilizer are the most common fertilizers.
2. Pesticides refer to all kinds of germicidal, insecticidal and herbicidal drugs used to promote and protect the healthy growth of crops. Pesticides play an active role in agricultural production and play an important role in the comprehensive control of plant diseases and insect pests.
3. Agricultural film is mainly used for mulching cultivation technology, which contributes greatly to the increase of agricultural yield and income and the production of off-season crops.
