Orchard ducks, planting and breeding, can make fruit trees and ducks mutually beneficial, reduce the cost of planting, and increase economic efficiency. The technical points are now described as follows: (a) species selection. Should choose strong resistance, suitable for both captive and stocking, eating a wide range of food, large food intake, strong digestion of duck varieties. (b) Stocking time. According to the situation of feed resources in orchards, orchard ducks can be divided into stocking and captivity. The most suitable period of restocking is the period of activity in the garden and the period of plant growth, generally from mid-April to the end of October. At this time, the grass grows abundantly in the garden, and there are many by-products of fruit trees. Ducks can eat various grasses, wild herbs, plant flowers, leaves, fruits, etc. as well as a variety of eggs, crickets, crawling insects, caterpillars, and surface insects. And other animal foods. Adult ducks can be stocked in orchards throughout the year. (3) The garden ducks are awkward and clumsy. They cannot feed on trees. All fields with good soil and water resources, and planted with grass and old pears, persimmons, and pomelo can be stocked. (D) stocking methods 1, stocking density. According to the size of the duck to determine the stocking density, should be the principle should not be dense. Ordinarily average 20 to 30 ducks per 0.067 hectares of orchard are stocked. 2. Demarcate the rotation area. According to the number of stocking ducks and the area of ​​the park, the rotation area was demarcated, and a 50 cm high nylon net was used to circle several areas. When the orchard area is small and the number of ducks is small, it may not be partitioned. However, intermittent grazing should be carried out according to the growth and reproduction of weeds and insects in the park. Ducks should be provided with drinking water in the duck area. 3, on time feeding. In order to supplement the lack of feed, feeding ducks should be fed in a timely manner. 4 weeks old (young duck) can be stocked in the orchard. Each morning and evening should be supplemented once, to supplement the lack of energy, according to the principle of early feeding half a full night to determine the amount of feed, and reduce the number and the number of feedings, prompting the duck to eat freely. During the main period of stocking, supplements are provided after returning to the shed at night, and sufficient drinking water is provided. Before the young ducklings in spring are stocked, they must first exercise to adapt to changes in outside temperature before they can enter the stocking garden. 4. Shed construction. Orchard ducks also need sheds for night feeding, drinking and egg production. According to local conditions, the construction of plastic duck sheds can be achieved by using mountains and cliffs, and rebuilding old buildings. The building area of ​​the shed should be calculated at 6-7 ducks per square metre. A certain activity area should be circled before the shed and a hopper and a drinking trough should be placed in the shed. 5, prevent animal damage. Stocking ducks must prevent the beasts such as the Lynx and Weasel. The use of nylon mesh enclosures is an effective safety precaution. However, it must also be managed by dedicated personnel to clarify responsibilities. Especially with young ducklings, it is more important to prevent rat damage. 6, epidemic prevention. Adhering to the principle of "prevention as the main and prevention as the most important thing," we will follow regular epidemic prevention procedures, conduct regular vaccination, and do a good job of prevention and control of disease. 7, to prevent poisoning. When fruit trees in duck farms must be sprayed with pesticides, the use of highly toxic pesticides should be strictly prohibited, and biological pesticides or low-toxic and highly-efficient pesticides should be used. During the spraying period, fences are grazing in order to avoid duck poisoning. The ducks can also be kept for 5-7 days until the toxicity of the pesticides disappears and they are placed in the stocking area.
