摘要

Fenlong farming technology was introduced.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.
