The Economic Benefits of the Factory-cultured Rana sylvatica in the Greenhouse Five-in-one, Full-function Culture Pond

The Economic Benefits of the Factory-Farmed Rana sylvatica Greenhouse Five-in-a-One Fully-Functional Culture Pond The Rana sylvatica breeding currently includes three methods: greenhouse farming, outdoor construction farm breeding, and field seal ditch stocking. However, the economic benefits of greenhouse farming are even more pronounced. Rana sylvatica is mainly eaten by insects. The live larvae of greenhouse frogs are mainly mealworms, maggots and maggots. In addition to the use of bran for Tenebrio feeding, the other two kinds of bait can be kept with livestock excrement or non-toxic organic waste, which greatly reduces the cost of farming. Therefore, it can be said that Rana sylvatica breeding is an emerging industry with a small amount of capital and quick results. Sunlight Greenhouse investment 15,000 yuan (400 square meters). Feeding two rooms for tenebrio molitors, plus a feed cost of 5,000 yuan, can raise 8 to 10 million baby frogs, and can produce about 20,000 female frogs in the year. Calculated according to the lowest market price, each 5.00 yuan, the output value can reach More than 100,000 yuan, not only can recover the investment that year, and there is a high economic return.

PC Board Venlo Greenhouse

Venlo structure is a popular one at present. This architecture uses horizontal girder as main bearer, forming a stable structure with columns. There is consolidation between horizontal girder and column, and hinge is used to connect column and foundation.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. The steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using the hollow double-layer or multilayer PC board.
PC board is mainly made of PC/PET/PMMA/PP materials, it need sun screen coating to resist ultraviolet resist and ageing, and it is also required to be anti condensation and antidrug.
As a kind of light material, use PC board can greatly reduce the weight of greenhouse structure, and corresponding reduced the size of the steel frame, which saving the cost of steel.
