宁南旱作农区是中国经济比较落后,生态环境十分恶劣的地区。西部大开发以来,该区苜蓿人工草地建设取得显著成就,如何在干旱条件下提高苜蓿产草量,成为该区生态经济农业研究的战略课题。根据不同的施肥模式试验,研究探讨了该地区苜蓿高产施肥技术措施,针对宁南地区的农业生态条件,提出适宜该区苜蓿高产施肥技术措施与施肥方案,常年降水不足400mm的宁南旱作农业区,在一定的施肥水平下仍然可以实现高效草地生态经济农业。生态经济农业(EcologicaleconomyAgriculture):简言之就是“产业化的生态农业”,是农业生态学、区域经济学和生态经济学理论在农业上的应用,不同于传统意义上的生态农业,是基于生态农业基础之上的新经济时代农业和农村经济的组织形式,其完善了生态农业理论界面的不足,将生态农业与农业产业化经营实现了有机结合,解决了农民组织化程度低、小农经济难以与大市场对接的问题。
The farming area in southern Ningxia is a region where China’s economy is relatively backward and the ecological environment is very poor. Since the western development, remarkable achievements have been made in the construction of alfalfa artificial grassland in this area. How to increase the yield of alfalfa under drought conditions has become a strategic issue for the study of eco-agriculture in this area. According to the experiment of different fertilization modes, the technical measures of high-yield fertilization in alfalfa in this area were discussed. According to the agro-ecological conditions in southern Ningxia, the technical measures and fertilization schemes of high yield fertilization for alfalfa in the area were put forward. Area, at a certain level of fertilization can still achieve efficient grassland eco-economic agriculture. Ecology Agriculture (EcologicaleconomyAgriculture): in short, “industrial ecological agriculture” is the application of agricultural ecology, regional economics and ecological economics theory in agriculture. Different from the traditional ecological agriculture, it is based on ecology On the basis of agriculture, the organizational forms of agriculture and rural economy in the new economic era have perfected the insufficiency of the theoretical interface of eco-agriculture, and realized the organic combination of eco-agriculture and industrialization of agriculture. It solves the problems of low degree of peasant organization and difficulty of peasant’s economy Docking with the big market problems.
