First, the significance of raising ducks in rice fields
Rice field duck farming technology is a comprehensive and environmentally friendly ecological agriculture cultivation technology. It plays an increasingly important role in vigorously developing organic rice and improving agricultural benefits. It has many advantages unmatched by other cultivation techniques and is widely recognized in rice production. It has good herbicidal effect and unique de-worming ability. The simple technical requirements and the greater level of benefits have been welcomed by farmers. It is a key technology for the production of organic rice.
Organic rice refers to substances that do not use synthetic fertilizers, pesticides, growth regulators, etc. in production, do not use genetically engineered organisms and their products, follow natural laws and ecological principles, according to the production standards of organic agricultural products. Sustainable agricultural technology, coordinating the relationship between planting and aquaculture, and promoting ecological balance.
Second, rice field duck farming technology
1. Rice paddy raising technology is to raise a certain number of ducks in the rice paddy field during the rice growing season, so that the ducks can effectively remove the weeds, control the pests, and fertilize the soil while growing and developing in the rice fields.
2. Method of raising ducks in rice fields:
(1) Brooding: The ducklings are required to be shelled 45 days before the ducking (before about May 1st), and the ratio of male duck and female duck is selected to be 1:4. When you are feeding at home, you should choose a place with water, let the ducklings exercise in the water, and fix the ducklings in a way (such as screaming, whistling, etc.).
In order to put it in the field, listen to the password when feeding, and at the same time do a good job of epidemic prevention and careful brooding. Purchase ducklings according to the rice paddy area plan (minimum 10% mortality) to ensure sufficient quantity. Duck breeds should be strong and adaptable, preferably local ducks.
(2) Preparation before ducking: Prepare the surrounding nets and duck house materials in advance, and seal the rice fields around the rice fields before the ducks to prevent the ducks from running to the adjacent rice fields. The duck house is built on the rice paddy. The height of the duck house is 80 cm, the length is 180 cm and the width is 140 cm. It is closed on the upper and west sides or the north side. The duck house is raised above the ground to prevent the duck from being wet. 2-3 duck houses.
(3) Number of ducks to be released: 100-120 ducks per hectare of rice fields, and more weeds in the field, otherwise less. The ratio of male ducks to female ducks is 1:4 in order to enhance the ability of the field to move.
(4) Ducking time: Put the ducks in time, usually around June 10, you can put the ducks after the seedlings are slowed down, but it is not too early to put the ducks. You should choose the ducks at 10 am and the ducks in the sunny weather. After the field, there is usually no need for manual care. Ducks should be placed in the ducks for about 45 days. After the ducks are fed, they should be fed ducks and trained ducks to make the ducks obey the password.
(5) Field feeding: generally feeding once a night, generally not afraid in the morning and noon, feeding more ducks, eating less grass, less activity. In the later stage, if there are few ducks and grasses, increase the number of feedings, accelerate the growth of ducks, and increase the commercial value of ducks.
(6) Collecting ducks in time: Ducks feed on weeds, larvae and adults in rice fields in the rice fields, and collect ducks in the early stage of grain filling after rice emergence to prevent ducks from eating rice ears and avoid affecting rice yield. After receiving ducks, male ducks can be sold. The female duck can be bred into an egg duck.
Third, the benefits of ducks:
1. Cost: The cost of purchasing ducklings is 2.5 yuan per bird. The cost of feed and epidemic prevention before brooding is 2.0 yuan per duck. The cost of ducks in the paddy fields is 1.5 yuan per duck. The total cost per duck is 6.0 yuan.
2. Sales: Ducks can be sold directly when the rice fields are recovered, or they can be kept for sale in winter. When the rice fields are reclaimed, the weight of each duck is generally about 1.5 kg. The selling price is 8 yuan per kilogram, and each duck can earn 12 yuan.
3. Pure income of rice and duck: The cost of each rice duck is 6.0 yuan, the sales income is 12 yuan, the net income of each rice duck is 6.0 yuan, and the income of rice and duck per hectare is about 700 yuan. No pesticides are used for weeding or de-worming, the cost of pesticides is reduced by 300 yuan, and the total savings are 1,000 yuan. For example, if the net income of each paddy duck is 20 yuan or more in winter, the sales efficiency of organic ducks is higher.
The above price budget is for reference only.
Fourth, the role of rice duck:
1. Weeding: The herbicide effect of rice and duck is better than any chemical herbicide. The duck is in the rice field. The duck eats the grass in the ground. When growing up, it mainly eats the dicotyledon weeds. At the same time, the duck stepping can indirectly play the herbicidal effect.
2, pest control: pest control effect is more obvious, ducks can eat rice water weevil, stem borer, negative mud insects and other adults and larvae, reduce the damage to rice seedlings.
3. Increase fertility: Because ducks live in rice fields, their excretions become good organic fertilizers, improve soil structure, increase soil fertility, and increase soil fertility by about 15%.
4, increase production: ducks have the habit of natural arching, can play the role of cultivating water, conducive to loose soil, increase oxygen, promote rice root development, live rod maturity, increase rice 1000-grain weight and maturity, increase rice yield by about 7% .
The above is the rice field duck raising technology for your reference, and I hope to help you. Huinong School has more relevant agricultural technology knowledge. Continue to pay attention to Huinong School to answer questions during planting or breeding.
