However, relatively single product and homogenized development model make competition gradually intensify, and many once glorious rural tourist destinations gradually decline. Xishan District of Kunming City of Yunnan Province is taken as research object in this paper. Via literature research, field survey and depth interview, development process, status quo and existing problems of its rural tourism are deeply explored. Based on above research results, development idea, strategy and countermeasure for quality improvement and effect increase of traditional rural tourism destination are proposed, and cooperative development, mutual benefit and win-win are taken as the ultimate development goals.展开更多

It has characteristics of very deep tillage and evenly smashing soil,and can evenly smash soil without disturbing soil layers to complete the task of soil preparation. It can be widely used in cultivated land,saline-alkali land,lime concretion black soil,degraded grassland,etc. After the application of the technology in 34 crops in 24 provinces,it can increase yield by 10%-50% and improve quality by above 5%. Fenlong technology can increase soil reservoir capacity,enhance the infiltration rate of rainwater in soil and make " surplus" effect obvious. If the country plans and promotes the technology in 160 million hm^2 of land( including 67 million hm^2 of cultivated land,20 million hm^2 of saline-alkali land,6. 7 million hm^2 of marginal land and 67 million hm^2 of degraded grassland),the total volume of loosened soil in arable land will increase from 198. 1 billion to 840. 0 billion m^3,and the capacity of a " underground reservoir" will increase by 675 million m^3,while natural precipitation reserves will increase by 162 billion m^3. It can effectively solve food security problems and water resource problems such as drought,floods,and industrial,agricultural and domestic water shortages,as well as serious disaster hazards caused by groundwater that has been evacuated in China.展开更多

Basic composition of "physical fertility of Fenlong" and its effect of increasing production and improving quality of various agricultural crops are clarified. It makes crop yield increase by 15%-30% without fertilization and 15%-50% by not increasing fertilization amount and irrigation water consumption. It is proposed that "physical fertility of Fenlong" could be sufficiently excavated in the new times of green development. Fenlong has a key significance for rationally reducing chemical fertilizer,soil,water and air pollution,agricultural cost,improving the quality of agricultural products and human health level.展开更多
