The Efficient Ecological Agriculture Based On Livestock Culture Feeding With Planting Grass

Ecological agriculture is built up in accordance with principles of ecology and economics, the use of modern scientific and technological achievements and modern management tools, and effective experience in traditional agriculture. It can obtain a higher economic efficiency, ecological and social benefits of modern agriculture. And it is only way to promote eco-agriculture sustainable and healthy agriculture and rural economic development, efficient use of agricultural resources, and to improve farmers’ quality of life significantly. This paper reviews the development of ecological agriculture, ecological agriculture and the status at domestic and abroad. Foreign eco-agriculture construction mode, as well as successful experience in the construction of ecological agriculture achievements in China were introduced, and the deficiencies of ecological agriculture in China was also discussed.As Jiangsu Province is an important agricultural province, the economy is relatively developed. Farming, aquaculture production value are ranked in the nation. but the pressure caused by over appling fertilizer, pesticide is becoming serious. The further development of agriculture faced greater challenges. As eecological agriculture takes into account economic, social and ecological benefits, to ensure sustained, stable and coordinated development, the need for ecological agriculture is urgent.In this paper, the livestock experimental base of Jiangsu Academy of Agricultural Sciences at Yancheng was used as the research object. On the base of analysis of the social and economic situation and level of agricultural production of the experimental area, grass for a different grass-grass, grain-grass cropping pattern were designed to conduct a comprehensive analysis and comparison of different planting patterns of productivity, and feeding technical of livestock. The results indicated that the highest evaluation value is ryegrass-hybrid Pennisetum-goat model, followed by hairy vetch-hybrid Pennisetum-goat model. It is recommended to plant ryegrass, hairy vetch in autumn and plant hybrid Pennisetum and hybrid Sudan grass in spring. Compared With food-grass rotation, grass-grass cropping and livestock patterns reached to high economic efficiency. Hybrid Pennisetum cropping with ryegrass and hairy vetch cropping with hybrid Pennisetum reach high biological production and can feed more goats. Grass-grass cropping patterns and goat culture can produce high economic benefit, and overcome the environmental pollution caused by burning straw. In the system of livestock culture feeding with planting grass, grass roots and animal manure can increase the fertility of soil. Livestock culture feeding with planting grass can achieve efficient and intensive use of land resources, reducing fertilizer use. Livestock feeding with planting grass process without the using of pesticides, the livestock products are more secure.Through evaluation and ecological analysis, the optimum model was chosen. Using the model in appropriate areas, It can achieve high economic, social and ecological benefits.
