What is ecological agriculture ? Ecological agriculture refers to the use of the law of energy conversion between humans, living things and the environment, and the law of symbiosis and mutual growth between living things, combined with the local resource structure, to establish one or more "one industry-oriented, comprehensive development, multi-stage conversion, "Good cycle" efficient waste-free system. It is one of the important systems in the agricultural system engineering structure, and it is an important content to do a good job in the balance of "land-food" and "water-soil-fertilizer". For example, in recent years, there have been a variety of management contents such as "ridge rice ditch fish", "ridge rice ditch frog", "ridge rice ditch shrimp" and "melon vegetable fish" that have been promoted in various parts of Guangxi. Gongcheng Yao Autonomous County established a " breeding industry -biogas-planting" cycle model, taking biogas construction as a link, animal husbandry (mainly pig farming) and biogas promote each other, and biogas slurry and biogas residues promote planting industry (mainly food , Fruit). This is a typical ecological agricultural model .
Ecological agriculture, simply put, is the "three high agriculture (high yield, high quality, high efficiency)" under good ecological conditions. It does not simply focus on the output of the year and the economic benefits of the year, but pursues a high degree of unification of the three benefits (that is, economic benefits, social benefits, and ecological benefits), and puts the entire agricultural production on a virtuous cycle of sustainable development. The human dream of "green mountains, green water, blue sky, and all produced green food" has become a reality.
Since the 1980s, kai has seen the emergence of ecological agriculture in some agriculturally developed countries in the world, which has attracted widespread attention from all countries. The development momentum is fast and there is an irresistible trend. European economist Willie DeWold predicts that due to the terrible "mad cow disease" in Europe, the world ’s ecological agriculture (or organic agriculture ) will have a large development in 5 or 6 years. It is estimated that ecological agricultural products It will be 10% higher than it is now.
Ecological agriculture is a new type of agriculture gradually formed along with the continuous development of the entire agricultural production. In order to do a good job in ecological agriculture construction, on the one hand, we must pay attention to summarizing and promoting the experiences and practices suitable for ecological agriculture in our traditional agriculture , such as: reasonable rotation, planting green manure, applying organic manure, sloping slopes, and constructing horizontal horticulture. These are measures that farmers are very familiar with and willing to accept. On the other hand, we must step up research and vigorously promote new advanced ecological agricultural technologies, such as photolytic membranes, biological pesticides, biological fertilizers, and straws developed to reduce white pollution. Returning fields, water-saving irrigation, etc. Practice has shown that in the construction of ecological agriculture, only when two measures are combined can the effect be better.
Ecological agriculture can be said to be a huge agriculture. Therefore, to complete this very complicated and arduous task, we must adhere to the principle of "agriculture, forestry, animal husbandry and sideline fisheries, comprehensive management of forests, forests, and roads". Based on investigation and research, we must do a good job of construction planning and promote different types of local conditions Ecological agriculture construction model. Practice shows that no matter what kind of ecological agriculture model? We must highlight three major measures. This is the use of biological measures (such as: planting trees, planting grass, increasing green manure, etc.), engineering measures (such as: big rivers and rivers, horizontal terraces on slope farmland, etc.), cultivation and cultivation. Measures (such as: reasonable rotation, deep tillage and less tillage, sloping slopes, returning straw to the field, increasing fertilizer application, etc.). These three main measures are complementary and indispensable.
