In the case of paddy field fenced ducks, under the condition of no cultivating, no weeding and no pesticides to prevent pests and diseases, the paddy fields with less ducks increase 40-55 kilograms of rice and 50-60 kilograms of ducks, and the net income per mu can reach 600 yuan. . Farmers claim that ducklings in paddy fields are “commandos for pest control, live weeding machines, and natural fertilizer plants†and are a good technique for wealthy farmers. Both early and late rice and one-season paddy fields are suitable. Ducklings choose small and medium-sized duck breeds with strong viability, adaptability, and stress resistance, such as lakeside ducks, Jianchang ducks, etc., to adapt to the characteristics of rice cultivation with “small nests and dense plantings†so that ducks can be found in rice fields. China can walk freely. The fortress is a place for ducks to inhabit, and it can be built on or in the center of a field in Tianjiao. The base is very simple on the corner of Tianjiao. Just place a 1.5m, 1m, and 1m rain and shade shed on the corner of the field. The ramparts in the center of the field are slightly more complicated. The habitat is in the shape of a ditch and a ditch, and the middle mud dipped to the sides.埂 20 20-25 cm above the water surface, 33 cm wide; 65 cm wide and 50 cm deep. The length of habitat is based on 25 cm of each duck. Preventing escape from obstacles can be made into fences using bamboo fences, branches, etc. Density of newly hatched ducklings cannot be passed. According to the size of the duck group, the natural hillocks along the paddy fields will be fenced around the field ridges; The height of the fence is 35-45 cm, and it is fixed with a bamboo pole. If the field is higher than 45 centimeters and the wall is steep and smooth, it may be surrounded by the low part of the field (including the inlet and outlet). When the stocking is planted in the paddy fields in due time, the ducklings will be placed on a 10-25 day old and 100-200 g body weight depending on the temperature. Medium fertility fields generally have 25 acres per acre, and 30 fertility fertilisers in order to facilitate ecological benefits. Rational feeding of raw materials to do a good job of Ping-based biological feed, supplement biological feed, protein, minerals and trace elements. Mu Ping Ping 150-200 kg, after Ping Ping every 10-15 days Mu catch 300-500 kilograms of livestock and poultry manure (to avoid chasing human excrement), superphosphate 1.5-2 kilograms, trying to grow Ping Ping slightly Greater than the consumption of ducks. Reference ratios for other nutrient ingredients supplements are (%): corn 40, wheat bran 25, rice 10, soybean cake 15, fish meal 5, talcum powder 2, calcium carbonate 2.5, table salt 0.5. The ducklings were fed 1 time in the morning and evening. The feeding principle was “feeding half a night before feeding enoughâ€. As the age increases, you only need to add a small amount of supplements every morning to boost the fattening. When the field management ducklings are stocked, it is during the rice delivery period that field management should be strengthened. The first is the management of the water layer, which requires a large amount of water for jointing rice, booting, and heading, and it can be filled with deep water. Generally, the water depth is maintained at more than 10 cm. The second is to check the occurrence of rice pests and diseases. The third is to observe the activities of ducks in the field, whether the growth and development is normal, whether the fence is damaged, and find that the problem is solved in time. Prevent and treat diseases that produce mildew, stinky and rotten, and cannot feed ducks. Use 25% of children's sterilizers to disinfect the fence with 2% lime emulsion. 20-day-old ducklings were inoculated with duck plague vaccine. When it is appropriate to harvest duck rice and enter the stooped period of loose seeds, it is necessary to timely withdraw Tiancheng ducks. As a result, the ducks have grown to about 2 kilograms per kilogram and their feeding ability is extremely strong. The timely recovery can avoid the ducks from eating grain.
