Farmers can choose to raise ducks rearing in front of their houses in a free space. The varieties are Beijing Duck, Tianfu Duck and Cherry Valley Duck. The method of adopting tree bar flat cages is as follows:
Breeding requires farmers to determine the scale of feeding based on the site and economic conditions. Generally, each batch can feed 100 to 200 and buy the next batch of ducklings 15 days before slaughter. Feeding venues should be dry, ventilated and sunny, sheltered from wind and rain, heat and heat, and filled with feed troughs and drinking troughs. Eat freely and ensure drinking water.
In winter and spring, small groups of breeders can use carton boxes, baskets, straw, cotton, and heated water bags to keep warm. Each box contains 25 animals. After feeding and drinking water, they can be put into the nest. The brooding temperature ranges from 1 to 7 days at 27°C, and from 8 to 24 days at 24°C, depending on the weather conditions. After the ducklings have been released, the temperature of the ducks will be low if they play the pile or if a "lean and thin" call occurs in the nest. The ducklings are free to move and have an even temperature distribution. In the spring and autumn, the general insulation is about 7 days, and the winter insulation is more than 10 days. In summer, it is important to prevent the heatstroke from cooling. The ducklings are defrosted and raised on a high bed. The height of the tree bed is 0.8 to 1 m. The tree bar has a gap of 1 cm. The duck dung is leaked into the ground. The bamboo bed curtains surround the tree bed. .
Density of light illumination 1 to 7 days old breeding 25 to 35 per square meter, 8 to 14 days of age feeding 18 to 25 per square meter, 15 to 21 days old breeding 12 to 18 per square meter. The density should be thin in the summer and slightly greater in the winter. 1 to 3 days old using light for 24 hours, 4 days after the use of natural light, sooner or later take the lights to feed.
After feeding the ducklings, they should start drinking before drinking. When drinking water, add the appropriate amount of glucose to the water. After drinking water, sprinkle the swelled broken rice or crushed corn on the plastic film and teach the ducklings to eat. After feeding, feed the ducklings with full-priced pelleted feed. After 15 days of age, feed the medium-sized duck feed pellets. Feed less frequently, fully feed, feed regularly, feed six times per day and night, including 6 am and evenings. Feed each at 10 o'clock. In order to reduce costs, farmers can feed animal heart and lung, meat residue, corn bran, sweet potato, melons and other feed. Do not lack of drinking water, diligence for litter, frequent cleaning duck dung to prevent moisture and animal damage.
Greenhouse Drip Irrigation System
Fertigation is using your irrigator to fertilise the plants and soils as you water, which is the most efficient and advanced practice of fertilization. Aid of pressure system (or natural divide terrain), the soluble solid or liquid fertilizer, according to the soil nutrient content and crop fertilizer regularity and characteristics of species, with the fat of with irrigation water, through a controlled water supply pipeline system, supplying, the compatibility, water through the pipe and drop head form drip irrigation, uniform, regular, quantitative, infiltration area crop root growth and development, make the main root soil always stay loose and appropriate moisture content, at the same time according to different crop fertilizer characteristics, environment and soil nutrient content in soil; Crops in different growth phase water requirement, the different development stages of the fertilizer rule is the demand of design, the water and nutrient timing quantitative, provided directly in proportion to the crops.
