Duck culture technology in paddy field

Raising ducks in rice fields can also be called "rice-duck co-practice". The main technical measures are as follows: In 2003, barnyard grass, weeds and insects were not found in the field without applying other fertilizers and pesticides. After ducklings were put into rice fields, they used rice fields as breeding grounds, moved around and ate weeds and insects in the fields. Not only do ducks grow fast, but also rice tillers vigorously, and the number of effective panicles is greatly increased. Because ducks will eat the ear after the ear of rice, they should be raised indoors at the beginning of the ear of rice, and the individual weight of ducks is between 1.0- 1.25 kg.

Although ducks eat weeds, they don't eat rice leaves. This is really called magical natural farming. It is more ideal to raise ducks day and night in rice fields. Ducks have better visibility at night and like to eat grass in group activities at night. At night, as long as someone approaches, they quickly run from the ridge to the ground and are not easy to be stolen. However, considering the rat damage, it is kept in rice fields from 4 am to 5 pm every day, and kept in fences at other times. (1) Weeding effect: The weeding effect is very obvious after the ducks are transplanted for ten days, because the size of ducks is directly proportional to the size of rice seedlings. Therefore, compared with the plots with herbicides, there are no weeds, which are quite clean, with high tillering rate and high plants.

There are no weeds in the field because:

First, ducks eat weeds with their mouths wide open;

Second, ducks directly eat weeds such as barnyard grass buried in the ground;

Thirdly, ducks use muddy water with their mouths or claws to float ungerminated weed seeds out of the water and bury grass in the mud;

Fourthly, the duck's continuous raking reduces the sunlight transparency of muddy water and hinders the photosynthesis of weeds.

(2) Insect control effect: The rice leaf miner and mud worm which are not put into ducks are more harmful and have to be sprayed with pesticides, but they are harmless to pests when put into ducks' rice fields, and the pests become a dish for ducks. Other pests were also eaten by ducks, so don't worry. Because ducks often stimulate plants, promote plant hardness, reduce ineffective tillers, have good ventilation and light transmission, and have no rice blast and sheath blight.

(3) Mud soup harrow function

Ducks keep turning around in the soil with their mouths or claws, raking the ground. It used to be said that it is better to use manure once when pushing with a lawn mower. The duck's rake is exactly the same. The field water in the duck-raising community remained in a state of precipitation for two consecutive months, thus promoting the growth of rice.

The function of mud soup can be roughly understood as:

First, ducks stir the water in the field to increase the oxygen in the water; the people

Second, the oxide layer on the site surface gradually thickens due to continuous stirring;

Thirdly, the continuous stirring of muddy water promotes the activity of microorganisms and the decomposition of organic matter, so that rice fields can effectively absorb nutrients in the soil;

Fourthly, the harm of biogas gradually disappears due to the agitation of muddy water;

Fifthly, the muddy water promotes the water temperature to rise at night, resulting in thermal insulation effect;

Sixth, water inhibited the germination of weeds;

Seventh, stimulate rice seedlings and promote tillering.

(4) Nutrient supply effect

The excrement discharged by ducks eating weeds and pests is a rare nutrient needed for rice growth. So in the paddy field where ducks are raised, rice grows vigorously. Otherwise, pests will run rampant and grass seeds will germinate, which will only bring disaster to rice production.

X. water layer management of duck breeding in paddy field

During the two months of raising ducks in rice fields, the water quality has been kept in muddy water, and keeping stagnant water will improve the grass killing effect and fertilizer efficiency. The water layer should be kept above 10cm in vegetative growth period, and 20 days before heading in mid-July in reproductive growth period. In order to resist the chilling injury, shallow water below 10cm should be irrigated after heading, so as to improve root ventilation conditions and increase seed setting rate.

XI。 benefit analysis

(1) Economic effect: Because a duck excretes more than 10 kg of feces in the rice field during the period of raising ducks in the rice field, it can be directly used as a rice fertilizer without fertilizing the rice field; In addition, because the water has been stored in the rice field during the rice-duck farming, there is no need to drain and dry the field, and there is little waste of water. Compared with conventional rice fields, it can save more than 46% of marine pollution resources, and the price of pollution-free duck rice produced is about 50% higher than that of ordinary rice. Save the feed cost of raising more than 200 ducks per hectare, and the net increase effect is about 1.200 yuan. The rice produced by duck breeding technology in paddy field is registered as "Tangwangya" rice, which is a high-quality rice produced by biotechnology according to organic food standards without using any chemical fertilizers and pesticides. It is a new product of "Tangwanghe" brand green rice series processed by Japanese "Sasaki" advanced processing equipment. The products are selected without scouring, crystal clear, delicious and nutritious, which is the best choice for people from all walks of life to live healthily and give gifts to relatives and friends.

(2) Ecological benefits: Raising ducks in rice fields, because it does not need chemical fertilizers, pesticides and herbicides, not only greatly saves costs, enriches soil fertility and protects the ecological environment, but also is a new change in the concept of rice production, and it is a new ecological agriculture technology with vitality and broad prospects.

(3) Social benefits: The rice planted in this mode is pollution-free and has high benefits, which has universal guiding significance for the sustainable development of rice production. At the same time, people eat pollution-free rice, which is conducive to maintaining good health and prolonging life. Moreover, the technology of raising ducks in rice fields is easy to learn and operate, which is suitable for large-scale promotion. It is one of the effective and practical technologies to increase agricultural efficiency and farmers' income. It is the latest cutting-edge science and technology agriculture that combines animal husbandry production with rice planting, tradition and modernity, and it is a major innovation in rice production technology. The popularization and application of this technology will have a great impact on rice production in our county, our province and even the whole country.
