Many materials in life are garbage if they are not used. In particular, waste can be used for secondary use if it is properly used. Let's see if wood chips (sawdust) can be used more. Sawdust refers to the sawdust and shavings left by the processing of wood. Fertilizer is used to ferment the sawdust chips into organic fertilizer. The principle of fermentation of different materials is the same, but the indicators in the fermentation process are different, and the operation is different. There are also differences. Now take woodchip fermentation as an example. Let's take a look at the fermentation process.
1, regulate moisture. In the fermenter, pour out the wood chips in the bagged material, apply water to wet it, and grasp the proper moisture to be 60-65%. Then, add 1 kg of golden bacon sawdust starter culture bacteria to each cubic wood chip and mix well.
2, build a heap fermentation. Build a heap while spreading the fungus, heap height 1.2 ~ 1.5 meters (remember not less than 80 cm), width 2 meters, the length of the heap can be adjusted according to the number of fermentation materials, the general length of not less than 2 meters, a single fermentation reactor total The volume is not less than 3 cubic meters. After the sawdust fermentation was completed, a thermometer was inserted into the stack to observe the temperature change.
3, fermentation overturned. About one week after the construction of the reactor, the temperature rises above 60°C. When the high temperature lasts for 1 to 2 days, the first turning of the reactor is performed. When the reactor is turned, pay attention to the degree of mixing of the materials, so that the turning process also becomes a mixing process. After the first tumbling, the temperature again reached a high temperature above 60° C., and the second tumbling was performed. During the tumbling process, the partially dry material was found, and the water was sprayed until a suitable moisture content was applied. The third and fourth turns are the same as the second turn. Afterwards, it enters the wood chip fermentation stage. The temperature is between 45 and 50°C. At this stage, the fermentation stack can be turned up one or two times as required, and finally it is finished at the end of the fermentation process.
4, inspection standards. After the wood chips have been fermented, the color is brown, and the actinomycetes cover the entire pile. The material has soft and elastic feel. This indicates that the wood chips have been fermented and matured. The whole fermentation process is completed and the material can be tested out of the tank. Wood chips after fermentation are required to pass the examination of the physical and chemical properties of products such as moisture, pH value and EC value. General: pH 5.5-7.5, EC value less than 1.5, moisture control 30% to 40%.
Fermentation of wood chips with a goldfish fertilizer starter is fast, the amount of addition is small and the cost is greatly reduced, the cost is less than one-third of that of similar foreign products, the operation is greatly simplified (“doll-type” operation), and the finished product made of fermentation is intrinsic Nutrition, color, appearance, and odor are all greatly enhanced and are highly valued by customers at home and abroad.

Single Greenhouse

The bearing structure, fixed film systems and installation of this greenhouse is relatively simple. And due to it, raw material and manufacturing costs are affordable. Except the high strength woven film is higher, other kinds of antidrop film are economical. In general, the comprehensive cost of film greenhouse is lower 30% ~ 50% than the same size and specifications of the other types of greenhouse.
