Tong Liao Area Ecological Agriculture Developmen

Petroleum agriculture is based on petroleum derivatives.It takes the production data of low cost and high efficiency and factors(such as mechanized farm machinery,chemical fertilizers,pesticides,and other high-tech)instead of the means of production and factors of expensive traditional agriculture(such as human,animal etc.).Its high investment,high output and this has the characteristics of good economic benefits,but also saves time and effort.Therefore,in the 50 years since twentieth Century,oil and agriculture have been developing rapidly,so that the pattern of world agriculture is a new look.Since the beginning of last century in 50 s is one of the world's population explosion,because the world food problem caused by a surge in population growing,the contradiction between supply and demand of grain and oil is unusually sharp,agriculture in order to solve this contradiction has played a crucial role,so the oil of agricultural industry is a milepost of world agriculture development history.But over the past few decades,due to the unprecedented expansion of oil agriculture,because of its negative effects brought about by the use of a large number of oil derivatives also cannot avoid-massive consumption of petroleum products to the world energy crisis,the extensive use of fertilizers in the increasingly barren land,the extensive use of pesticides has resulted in a lack of ecological balance serious damage to natural resources,a series of food safety problems and so on.People abuse and oil agriculture brought by the contradiction between the good natural environment and safety of agricultural products to become more and more prominent.Ecological agriculture is a new agricultural development mode of agriculture and its following the oil after the oil agriculture are quite different,it It applied the principle of ecological agriculture and forestry,animal husbandry,vice,fishing,etc,will be valuable experience in traditional agriculture and the organic combination of high-tech achievements,pay attention to agricultural production and ecological balance,and the contradiction between the environmental protection coordination,form virtuous circle between ecological environment and economic development.Not only can bring higher economic benefits,but also bring the environmental benefits and social benefits.It has solved the disadvantages of oil and agriculture more and more,it will become a new direction of agricultural development in the future.Taking Tongliao area as the research object,From tongliao city of geographical environment,climate characteristics,the ecological agriculture development present situation and existing problems on a thorough analysis and argumentation,and actual case proves that the traditional oil grievous abuses existing in the development of agriculture in the local agriculture and so on.In order to solve these problems,based on the deep research in the theory of ecology and ecological agriculture,and combining the tgo actual situation in the region,the innovation is out of a new type of ecological agriculture development model,the model will be greenhouses and crops buried underground irrigation technology combined with frog breeding,constitute a set of ecological agriculture pattern,buried underground irrigation technology has solved the local water resources shortage of traditional agriculture waste of water resource caused by excessive and accelerated the problem of land salinization,combination of greenhouses and buried underground filling and solved the problem of the drip irrigation system used in winter also solved the problem of the wood for the winter at the same time,the frog provide some manure for crops,farmland of insects to provide food for wood,so constituted a set of simple ecological prevention and control of plant diseases and insect pests of ecological system.Finally hope that through this article research,ecological agriculture is this model a to solve the current pass vast areas of agricultural economic transformation path,enough to solve the problems in agricultural development in tgo provides a new train of thought and theoretical basis.
