1. The structure of the fermentation bed requires the direction of the pigsty to be east-west and south-facing. It can be made into a greenhouse or single-row or double-row structure according to local conditions.
For the needs of ventilation, the pigsty is best equipped with “four windows complete†(“four windows†ie skylights, underground windows, common windows and windscreens). The pens are separated by fences to prevent bad odor blockage in dead corners. , Stay and strengthen the air mobility.
The area can not be too large or too small. For example, the recommended area of ​​the Jinpo fermentation bed is 20-45 square meters, which can effectively prevent or reduce the “bad bedsâ€, “blisters beds†and “mud bedsâ€. The appearance of the phenomenon.
According to the local terrain, underground and semi-underground are made underground to prevent water leakage.
2. Production of Fermented Beds Take the production of the Gold Baby Fermentation Bed as an example. The unique "dry spread" and fool-type operation of the Gold Baby Fermenting Bed. As long as "one dose and one material" and "five layers of four-layer fungicide" are very simple and convenient.
For example, to make a 20 square fermented bed, 1 dilution. First dilute 2 kg of gold treasure compound (5:1 relationship) with 10 kg of rice bran or corn flour, flour, bran, etc., and divide into 4 parts; 2 then prepare 10 squares of about 2 tons of dry sawdust (the total thickness is not (below 50cm) divided into 5 parts; 3 first spread a layer of 10cm sawdust, then spread a layer of fungus, a total of 5 layers of sawdust four fungi; 4 pigs into the bed after completion of the shop, remember not to add water, the density of the pig More than 1.2-1.5 square meters per head, should not be small should be appropriate, the piglets reduce the appropriate points, two to three days began to start fermentation, decomposition of feces. The ginba dry-type fermentation bed is very simple and does not need to be fermented before adding water.
3. Maintenance of the fermentation bed The operation of the ecological fermentation bed is very closely related to the maintenance. The maintenance is directly related to the function and life of the fermentation bed. For example, the goldfish fermentation bed is well maintained without cleaning. How to maintain it?
3.1 Humidity The density of excrement, urine, humidity, and central layer should be controlled below 65%. The simple way to judge is: grab a handful of material by hand, and see that the water does not drip in the finger-tap is an appropriate standard, and the watermark is not visible. Too dry, dripping water too wet. Too much or too little moisture is not conducive to fermentation: too little water, slow fermentation of microorganisms. Too much water increases the temperature slowly, and the ventilation is poor. The formation of a local anaerobic environment promotes the work of spoilage bacteria and produces odors, and even a dead bed phenomenon. A slot must be made below the drinker to drain the excess water. In general, the bed surface humidity is about 20-30% and the middle layer is 50-65%.
Therefore, in the routine maintenance of the fermentation bed, the humidity in the fermentation bed is often observed and adjusted in time. The thirst on the bed is slightly sprayed with water, and the bed can be moistened with some dry litter, pushing the litter to promote mixing with other places, or pulling Dry out and go to bed.
3.2 Turning regularly, the depth is 20-30 cm. The frequency needs to be one or two times a week as required. Wet and wet are equal.
3.3 Ventilation Maintain good ventilation conditions. The sunroof discharges ammonia gas, nitrogen dioxide in the ground window, normal window drainage vapor, and the induced draft fan window enhances air flow during hot weather. When the temperature is high at noon, the sunroof is opened and covered at night. According to time, season and climate, reasonable ventilation measures should be taken to maintain the air requirement of the fermentation bed and be warm in winter and cool in summer.
3.4 After a long time, according to the subsidence of litter to add a certain amount of litter and bacteria, so that the litter layer is maintained at the appropriate thickness, so that the core fermentation layer, protective layer, buffer layer has its own space.
In this category, you will find test tube and stand in many various sizes and variations. For laboratory work, Test tubes and Test tube racks is an essential element of all labs. Test tube racks allow the test tube to be securely held upright so that nothing can run out while filling the tubes.
Measuring cup is another one of the basic consumable container in lab. Except Test tube racks, Yingmed also supply other lab device holder like Stand base, Lab Jack, Pipette Stand and Laboratary Clamp in this category. If you can not find the one you need, please contact our customer services for more details.
