Development of the technology to maintain the secondary natural environment in hilly and mountainous regions and the strategy to maintain sustainable farm management

为了维持丘陵山区的次生自然环境和可持续的农场管理，采取了以下许多技术和策略：1)引进耐酸和耐冷作物，如蓝莓、山药和紫荆；2)生产耐冷性增强的转基因水稻；3)在丘陵山区发展深水治理水稻种植。4)丘陵山区梯田系统水田土壤和水环境；5)畜禽粪便在作物生产中的应用；6)基于GPS和GIS的大型农林复合放养牛行为管理；7)池塘人工生态系统稀缺淡水鱼“Tetsugyo”（鲫鱼）放血。8)河流形成的天然乔木植被的保护；9)乡村风景的形象形成对农村农村保护意识和意愿的影响；10)丘陵山区农场管理和农场经济的维持策略。

The following numerous technologies and strategies were conducted to maintain both a secondary natural environment and sustainable farm management in hilly and mountainous regions : 1) Introduction of acid and cool weather tolerant crops such as blue berry, Chinese yam and Zizania 2) Production of transgenic rice plants with enhanced chilling tolerance, 3) Development of rice cultivation under deep flooding management in hilly and mountainous regions. 4 ) Soil and water environment of paddy field in terrace system in hilly and mountainous regions, 5) Livestock manure application for crop production, 6) Management of free-ranging cattle behavior in a large-scale agro-forest by GPS and GIS, 7) Bleeding of scarce fresh water fish "Tetsugyo" (Crucian carp) in artificial ecosystem of pond. 8) Conservation of natural tree vegetation established along with the stream, 9) Effects of image formation of rural scenery on consciousness and willingness to protect rural farming villages, 10) Strategies to maintain farm management and farm economics in hilly and mountainous regions.
