Can the straw be burned by farmers?

[China Agricultural Machinery Industry News] Recently, cold air swept through most of China, and at the same time many cities are still facing the madness of smog. On November 18, the Central Meteorological Observatory has issued an early warning of smog orange. In this year's analysis of the causes of smog by the environmental protection and meteorological departments, the issue of “stalk burning” in agricultural production has once again become a hot topic in the analysis of factors such as automobile emissions and industrial emissions, which once again attracted great attention and consideration in the industry.
Can the straw be burned by farmers?
Straw banned burning
At the moment, although the cold air has come a wave after another, the nationwide autumn harvest winter is still not over, and the straw that is the “waste” of agriculture is still in the “production” and “processed”. In November, the number of straw ignitions in Heilongjiang reached a new high, which made Heilongjiang suffer from public opinion and was under great pressure.
In fact, the propaganda of burning stalks is being done every year. The hazards of burning straw are also said every year. This year, the whole country is stepping up efforts to rectify the problem of straw burning. Such as: banner warning, drone monitoring, responsible sitting system, etc., Heilongjiang Zhaodong City and even villagers were detained for burning straw, but still can not stop the fire in the field. Under such tough control and suppression, the villagers were helpless: "The straw can't be burned, can we still do it?"
Why is straw burning repeated?
Straw burning has repeatedly prohibited the responsibility should not be shirked on the villagers, this is a chain, any one of them is the key to the stability of the chain.
First of all, with the changes in agricultural production methods and rural energy structure, the straw that was originally used for firewood cooking and heating gradually lost its value and began to be considered as “waste” in agricultural production. It has become a farmer. a burden. Secondly, at this stage, due to many technical limitations, the comprehensive development and utilization of straw is too low. In plain language, there is no money to make, then the villagers naturally will not bother to deal with those straws, one burns, simple Convenient.
Of course, the reasons for repeated incineration of straw burning are not lacking in the lack of responsibility and environmental awareness among the villagers. However, the key is not to find a better way out for the straw. At present, the means of suppression are not only depleting manpower and material resources, but also often causing public grievances.
Convenient choice at this stage: Mechanized returning to the field
In addition to burning, there is still a lot of way for straw to be burned. In addition to being pressed into pellets to make biofuels, it can also be used for power generation, industrial raw materials, edible fungus base materials, etc. After many investigations, it is found that straw returning is the world today. A measure of increasing fertility that is generally emphasized is to eliminate the air pollution caused by straw burning and to increase fertilizer and increase production.
With the continuous development of agricultural mechanized production and the continuous maturity of agricultural machinery technology, direct mechanization of straw mechanization has become an effective way to quickly and effectively treat surplus straw in large quantities, which can directly prevent the current stage of straw burning and greatly reduce environmental pollution. Straw mechanization directly returns to the field can significantly increase the soil organic matter content, enhance the ability of water storage and preservation, and can also implement straw returning at the same time of mechanical harvesting. It is simple and convenient, no need to bundle, no transportation, and achieves the true meaning. "Take it to the field and use it in the field."
In addition, the mechanization of straw directly returns to the field of agricultural machinery, expands the scope of agricultural machinery services, promotes the innovation and upgrading of agricultural machinery technology, and helps to improve the level of agricultural machinery. As the agricultural production in the fall of the country came to an end, many places came to the report of straw returning to the field. For example, this year, the mechanized returning rate of rice straw in Haimen City will reach 92%, and nearly 90% of the straw in Zhoukou will be used for returning to the fields...etc. It can be seen that the mechanization of straw has become a well-known and favored way.
The impact of smog is still continuing to ferment, and the problem of straw burning is still receiving attention. We sincerely hope that with the transformation of straw treatment methods, more advanced straw treatment technologies will be developed and applied in the future, bringing new vitality to the development of modern agriculture.

Aluminum Door Big HandleFEATURES:


Aluminium is a chemical element with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic and ductile metal in the boron group.

Light, durable and functional: these are the qualities that make aluminium one of the key engineering materials for various applications. We can find aluminium in the homes we live in, in the automobiles we drive, in the trains and aeroplanes that take us across long distances, in themobile phones and computers we use on a daily basis, in the shelves inside our fridges and in modern interior designs, but a mere 200 years ago very little was known about this metal.


 â€¢   Aluminum castings can allow the attainment of complex designs and forms. This means that manufacturers can easily order customized castings that will be suitable for their production
needs.
 â€¢   Aluminum castings allow producers to manufacture parts at an extremely higher and faster rate than other alloy materials. Aluminum Die Casting can also achieve near net shape so the process of machining can be eliminated to produce finished parts.
