Over very long time, human meals and clothing depended mainly on agriculture. While ever for the reason that ancient time, agriculture had always relied on a lot of human labor, which was topic to various kinds of natural conditions. So the development of agriculture was very slow. Through the 19th century, using agricultural machinery gradually improved the working conditions. Nevertheless, in agricultural production, it was the application of chemical fertilizers and pesticides that really elevated the agricultural output in per unit area.
Apply shows that, amongst all of the measures to increase the agricultural production, the position performed by chemical fertilizers is forty% to 65%. On the premise of the booming within the petrochemical industry, artificial ammonia and urea have realized giant-scale production, which makes the output of chemical fertilizer occupy a large proportion within the chemical products. In 1985, the total output of chemical fertilizer on this planet amounted to approximately one hundred forty million ton, which made it develop into one of the bulk chemical products. Lately, the development of nitrogen, phosphorus and potassium compound fertilizer and hint parts fertilizer has further meet the demands of different soil constructions and completely different crops.
In the early interval, folks used natural animals, plants and minerals to stop and treat crop pests and diseases. Until the late 19th century, after the formation of contemporary chemical business, folks started to make use of arsenic preparation to ksick beetles on potato, and use Bordeaux mixture to prevent and deal with downy mildew on grapes, so that agriculture began a new period of chemical prevention and treatment. During the 1940s, loads of pesticides and herbicides, comparable to organic chlorine, natural phosphorus, had been produced and widely utilized in agriculture, forestry, animal husbandry and public health. Nonetheless, a few of the pesticides throughout this interval have been rich in residues or poison, which caused ecological pollution, in order that they had been banned by many countries.
In recent times, a number of efficient, low-residue, low-poisonousity pesticides have been developed, including pyrethroid, which is a bionic pesticide and won’t pollute the environment. It has been put into industrial production. Consequently, bio-pesticides have become the most active areas in pesticide research currently.
What’s more, plastic film (akin to high pressure polyethylene, linear low density polyethylene, etc.) has been applied in trendy agriculture, which is used for mulching film or greenhouse seedlings. It could actually significantly improve the output of the crops, so it is now being popularized on a large area.
