Rice paddy duck rice paddy duck farming technology

Duck farming in paddy fields can also be called "rice-duck farming", the main technical measures are: 2003 rice duck plots in the field without other fertilizers, pesticides and insecticides under the conditions of the field can not see barnyard grass, weeds and insects. Ducklings put into the paddy field, the paddy field as a feeding ground around the activities of eating the field weeds, insects, not only ducks grow fast, rice tillers flourish, the effective number of spikes also greatly increased. Because the ducks will eat the rice spike after the rice spike, so the beginning of the spike should be returned to the duck house rearing, when the individual weight of the ducks between 1.0-1.25 kilograms.

Ducks eat weeds, but do not eat rice leaves, can be called magical natural farming. The effect of stocking ducks in rice paddies during the day and night is even more ideal. Ducks have better visibility at night and like to move in groups at night to eat grass. When people approach them at night, they run quickly from the ridge to the field and are not easy to be stolen. However, considering the rodent damage, they are released in the paddy field every day from 4:00 a.m. until 5:00 p.m., and the rest of the time they are kept in the enclosure. (1) Weed-removing effect: The weed-removing effect of ducks is very obvious when they are released ten days after transplanting rice seedlings, which is because the size of ducks is directly proportional to the size of rice seedlings. Therefore, than the application of herbicides in the plot is both weed-free and quite clean, high tiller rate and plants.

The reasons for the field being weed-free are:

One, the ducks eat the weeds with their wide mouths;

Two, the ducks directly eat the grass seeds of weeds such as barnyard grass buried in the ground;

Three, the ducks use their mouths or claws to muddy the water to bring the ungerminated weed seeds to the surface, and trample the small grasses into the mud and bury them;

The fourth is that the effect of the duck's uninterrupted raking reduces the sunlight transparency of the muddy water and impedes the photosynthesis of the weeds.

(2) Pest control effect: the paddy field without ducks had more damage from leaf miners and mud bugs, and had to be sprayed with pesticides, but the paddy field with ducks had no pests, and the pests became the ducks' meals instead. Other pests are also eaten by the ducks, so there is no need to worry. Because the ducks often stimulate the plant, promoting plant hardening, reducing ineffective tillers, good ventilation and light without the occurrence of rice blast and blight.

(3) Mud soup harrowing effect

Ducks use their mouths or claws to constantly turn the upper and lower soil for harrowing. In the past it was often said that pushing the ground once with a weed whacker is stronger than applying manure once. Duck raking is exactly the reasoning. The field water of the duck-raised plots was kept in a muddy state for two consecutive months, thus promoting the growth of rice.

The effect of mud soup can be broadly understood as follows:

One, the ducks churned the field water to increase the oxygen in the water; two, the oxidized layer on the surface of the field was gradually thickened because of the constant churning;

Three, the constant churning of the mud water promoted the activity of microorganisms and the decomposition of organic matter, so that the rice paddy efficiently absorbed nutrients in the soil;

Four. The hazards of methane gas gradually disappeared due to the stirring of the muddy water;

fifth, the muddy water contributed to the rise of the water temperature at night and produced a heat-retaining effect;

sixth, the water inhibited the germination of weeds;

seventh, it stimulated the rice seedlings and promoted tillering.

(4) Nutrient supply effect

Ducks excrete feces by eating weeds and pests are rare nutrients needed for rice growth. As a result, rice grows vigorously in plots where ducks are raised in paddy fields; if not, pests will run rampant and grass seeds will germinate, which will only bring disaster to rice production.

Ten, paddy duck water layer management

Paddy ducks during the two months of water quality is always kept in muddy water, keep stagnant water will improve the effect of killing grass and fertilizer efficiency. During the nutritive growth period, keep the water layer above 10cm, during the reproductive growth period, i.e., 20 days before the emergence of spikes in mid-July, keep the water layer above 20cm in order to resist the low-temperature cold damage, and after the emergence of the spikes, start to irrigate the shallow water below 10cm, in order to help improve the root aeration conditions and increase the fruiting rate.

Eleven, benefit analysis

(1) economic effect: due to the paddy ducks during the period, a duck excreted in the paddy manure in more than 10 kilograms, it is directly as a rice fertilizer, paddy does not have to fertilize; and because in the paddy ducks *** during the rice, paddy has been storing water, do not need to release the water to dry the field, very little water is wasted, compared with the conventional rice paddies, can save the marine pollution resources More than 46%, the production of pollution-free duck rice can be about 50% higher than the price of ordinary rice, more than 200 ducks per hectare due to the savings in feed costs, than conventional duck net effect of about 1200 yuan. After the rice paddy duck technology produced by the rice registered as "Tangwang duck" rice, is not applying any chemical fertilizers, pesticides, the use of biotechnology, in accordance with the standards of organic food production of high-quality rice, is the "Tangwanghe" brand of green rice, a series of new products, the Department of Japan "Satake" using It is a new product of "Tangwanghe" brand green rice series, which is processed by advanced processing equipment of "Satake" from Japan. The products are selected free of plucking, crystal clear, glutinous taste, rich in nutrition, is the people of all classes of healthy life of the necessary food and gifts to friends and relatives of the best choice.

(2) ecological benefits: rice paddy ducks, because it does not need chemical fertilizers, pesticides, herbicides, not only greatly saves costs, fertilization of the ground, the protection of the ecological environment, is a new change in the concept of rice production, is a new ecological agricultural technology with vitality and broad prospects.

(3) social benefits: rice planted according to this model because of its pollution-free, high-efficiency, for the sustainable development of rice production has a general guiding significance. At the same time, people through the consumption of pollution-free rice, is conducive to maintaining good health and improve life expectancy per capita, and paddy duck technology is simple to learn, easy to operate, suitable for large-scale promotion, is one of the effective and practical technology of agricultural efficiency, farmers increase income, is the livestock and planting of rice, traditional and modern combination of the latest cutting-edge technology of agriculture, is the production of rice technology, a major innovation, the technology of the The promotion and application of this technology will certainly give my county, my province and the country's rice production has a significant impact, will strongly promote the leapfrog development of rice production.
