The selection of geese breeding base

The ground of the geese breeding base should be flat, slightly inclined to the south or southeast, with a sunny leeward, the size of the site

To be appropriate, the soil structure is best sandy loam soil, this kind of soil drainage performance is good, can keep wild goose raise

Colonization of dry bases. The terrain should be high and dry, it is best to have shaded trees, convenient drainage, free from floods

The impact of disasters minimizes the impact of cold air in cold seasons, and helps prevent epidemics and disposal of faeces.

Exclude sewage and so on. Understand the natural climatic conditions of the wild goose breeding base, such as the average temperature, the most

High and minimum temperatures, rainfall and snow depth, etc., where summer maximum temperatures exceed 40°C

It should not be selected as a site.

The geese breeding base must have sufficient water and power. Drinking water for the wild geese, cleaning and sanitation

Water and water for personnel, etc., should be estimated, especially if the water supply in the dry season is sufficient.

A detailed survey to ensure long-term stability of water use. Water source is ideal for deep groundwater, followed by

water. Large-scale geese breeding bases are best able to create deep wells to ensure the quality of water. Dayan Breeding Base

For ground hatching and brooding, there must be lighting and heating equipment, especially large-scale wild geese breeding bases.

Lighting, incubation, heating, defecation, drinking water, ventilation, etc. all require electricity, so geese

Farming base power must be guaranteed.

The geese breeding base should be in a convenient place to ensure feed, products and supplies

The smooth flow of transportation. The distance between the geese breeding base and the main traffic trunk is better than 1,000 meters to prevent

The spread of the disease and the impact of the external environment. Wild geese breeding base should be far away from residential areas, factories and mines

Places such as businesses, tourist attractions and hospitals to ensure a quiet environment. If there are

In addition, the wild geese breeding base should be selected in areas where the grassland is vast, the grass is tender, and the growth is flourishing.

Geese eat a lot of grass. The quality of the grassland is closely related to the operating efficiency of the geese breeding base.

Good grassland can not only save the concentrate feed, but also increase the egg production and hatching rate of the female geese.

Engine Piston Parts

The piston is one of the main moving parts of the engine, is composed of combustion chamber components.
The pressure of the gas piston through the connecting rod to the crankshaft, realize the change from heat energy to mechanical energy.
The work condition is very bad, and the temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas contact, greatly alternating thermal stress and mechanical stress.
And by the serious corrosion of gas, and under the condition of boundary lubrication and cylinder wall friction and strong impact 1 times.
The piston in high temperature, high pressure, strong corrosive gas contact so that it has enough strength and hardness,
Heat resistance and good thermal resistance, high fatigue strength and corrosion resistance. For high speed diesel Engine Piston also requires light as far as possible.
In order to reduce the inertia force.
Marine piston large low speed diesel engine of the crosshead is usually combined.
The heat treatment process by normalizing and annealing, and iron pearlite are ferrite organization, has good heat resistance.
Piston alloy quenched and tempered steel has better heat resistance and corrosion resistance. The skirt with nodular cast iron annealing treatment, with good wear resistance.
