Since the emergence of greenhouses in China, there have been more and more people using greenhouses throughout the country. However, due to the special nature of the greenhouse structure, many agricultural tools are difficult to play in the greenhouse. There is demand for a market, so in the past two or three years, both domestic and foreign agricultural machinery manufacturers have been targeting this gap, and many small agricultural products that are suitable for use in greenhouses have been listed. From a functional point of view, these small-scale agricultural machinery are mainly divided into several types: rotary cultivation, sowing, fertilization, ditching and plant protection. Small farm machinery that circulates on the market is both domestically produced and imported. It is understood that China Agricultural Machinery Circulation Association imports of small agricultural machinery and equipment are generally priced at 6,500 yuan, there are two kinds of small domestic agricultural machinery, a price of 4,500 yuan or so, another kind of price of 3,500 yuan.
According to the introduction of agricultural technicians, the quality of currently imported small farm machinery is generally better than that of domestic products, and the overall operating quality and operating indicators of imported small farm machinery are also higher than that of domestic ones.
Whether it is domestic agricultural machinery or imported agricultural machinery, the functions of these compact and easy-to-use greenhouse agricultural tools are relatively simple. For instance, rotary cultivators cannot perform deep plowing. However, as long as you spend some money, you can support it.
Expert Tips: Buy imported greenhouses agricultural machinery should choose large manufacturers of famous products, buy domestic greenhouse agricultural machinery, should try to choose the more recent manufacturers of products.
Imported Bio-based Plastic Resin
Chemical plastic products bring people all kinds of convenience, but also bring unimaginable trouble. As some waste plastics will not degrade under natural conditions, the combustion will release harmful gases, causing difficult pollution to the ecological environment. So scientists around the world are starting to develop self-destructing, or autolytic, plastics that can break down on their own to solve the problem. Some call it "green plastic". Companies in many countries have introduced their own biodegradable plastics. Biologists at the University of Mitzgan in the United States first proposed the idea of "growing" degradable plastics. Using potatoes and corn as raw materials, they inserted the plastic's genetic material so that it could be artificially grown without harmful ingredients. Imperial Chemical Forests USES bacteria to make sugars and organic acids into biodegradable plastics. The method is similar to the fermentation process used to produce ethanol, except that the bacteria, alkaloids, turn the feed into a plastic called PHBV. Bacteria accumulate the plastic as a store of energy, just as humans and animals store fat. When the bacteria have accumulated as much as 80% of their body weight in PHBV, they break down the cells with steam to collect the plastic. PHBV has properties similar to polypropylene, a material that is stable even in humid environments after being discarded, but which degrades into carbon dioxide and water in the presence of microorganisms.
