Rice field fermentation bed duck key technology

Xia Xin Zhang Baoquan

Compared with the traditional duck-drinking model, the Jinbao rice paddy fermentation bed duck technology has the functions of labor saving, grain saving, provincial medicine, and power saving, which saves a lot of costs, increases economic efficiency, and can be slaughtered in advance for about a week. It can increase the weight by several hundred grams. It is an advanced and scientific breeding mode. The padding can use the local rice husks, which can greatly save the cost of litter. However, the rice field fermentation bed ducks often directly affect the efficiency of the fermentation bed due to some key problems. The following briefly introduces several key issues in the duck bed fermentation bed for the reference of the farmers in the use of the fermentation bed.

A, moistureproof and waterproof

Because the foundation of the fermentation bed is built on the basis of paddy fields, the rice paddy soil is damp. To prevent the litter from sucking water from the mud, it is also possible to prevent the rainwater from accumulating in the rain bed from soaking the fermentation bed and causing the fermentation bed to be scrapped. Therefore, in the production of fermentation beds to raise the fermentation bed surface, the following measures can be used: 1) make the ground type, you can use soil or bricks, pebbles, etc. laying in the bottom of the fermentation bed, so that the bottom of the fermentation bed above the paddy field surface at least Above 20 cm, the higher the layer height is, the better, and avoid rain or water soaking in the fermentation bed, where the cost of using local soils is higher; 2) Deeply digging the drainage ditch, speeding up the installation of drainage equipment, Drainage ditches should be dug as deep as possible, and the ditch depth should not be less than one metre to prevent the rainwater from soaking the fermentation bed too much. This is in line with the theory of fear of dampness in the Jinbao fermentation bed.

Second, according to the growth of the duck group stage management

The growth stages of ducks are not the same, and the size and excretion of excrement are not the same. Therefore, the density should be reasonably arranged. For example, for 25 days before, the goldfish fermentation bed culture can withstand the breeding density of 7-8 per square meter, but after 25 days With the gradual increase of excretion, the fermentation bed can not decompose the excess manure beyond the load of the fermentation bed. Therefore, the breeding density should be reduced. The “Golden Circle” or “ABC circle” system is recommended for the Jinbao fermentation bed, ie 25 Day before the use of a small area of ​​A circle, 25 days after the opening of B, C large pen home, such as the original 1 duck group is divided into 2, or 2 duck groups are divided into 3, or the original small area housing Replace the large-area housing with twice the area, and set a dedicated channel in the middle or at both ends to reduce the culture density and reduce the excretion, so that the fermentation bed can play a long-term, stable and sustained function.

Third, litter maintenance

The maintenance of litter also directly affects the decomposition rate of the ecological fermentation bed, and also affects the operation of the fermentation bed in the long term. Therefore, the frequency of turning over the litter is increased in the daily feeding work (eg, over 2-3 times per week). The tipping depth of the fermentation bed is 30-40 cm. If only 20 cm is turned over for a long period of time, it is very difficult for the manure to be fermented. And according to the need to add a certain amount of litter and strains, can not reduce the amount of cost savings, otherwise it will have the opposite effect, such as Jinbao suggested that 1 kg of starter to do 12-15 square, the amount is too small, the decomposition efficiency will be greatly discount.

IV. Disinfection of Fermentation Beds

To correct the problem that the fermentation bed cannot be disinfected, for the empty-barreled fermentation bed, the disinfectant can be normally sprayed without affecting the subsequent use of the fermentation bed.
