本文运用侯光炯教授提出的土壤肥力生物热力学理论,综合地论述了1980—1986年水田自然免耕技术综合研究的成果:阐明了水田自然免耕技术的增产机理;提出了一整套水田自然免耕技术:①水稻半旱免耕栽培技术;②小麦半旱免耕栽培技术;③水田免耕综合利用技术。对水田自然免耕技术大面积示范推广的综合效益(经济效益、生态效益和社会效益)进行了全面评述,证明了水田自然免耕技术有着无限的生命力和广阔的发展前景。
Based on the bio-thermodynamics theory of soil fertility put forward by Professor Hou Guangjiong, this paper comprehensively expounds the comprehensive research results of natural no-tillage technology in paddy field from 1980 to 1986: clarified the yield increase mechanism of natural no-tillage technology in paddy field and put forward a set of natural no-tillage technology : ① semi-arid no-till rice cultivation technology; ② semi-arid no-tillage cultivation technology; ③ tillage no-tillage comprehensive utilization technology. The comprehensive benefits (economic benefits, ecological benefits and social benefits) of large-scale demonstration and popularization of natural no-tillage technology in paddy fields were comprehensively reviewed, which proved that paddy field natural no-tillage technology has immense vitality and broad prospects for development.
