  1. The no - tillage and culture focus more on creating better conditions for microbe decomposing the crop residue compared with no - tillage. there are four principle in it : 1 ) successive capillary water circulation ; 2 ) successive no - tillage ; 3 ) successive multiple crop rotation ; and 4 ) successive " ridge and furrow culture ". by these devices taken, the soil accumulate more organic matter in shorter period compared with general no - tillage

    將秸稈混入土壤中分解，壟、溝搭配，保持土壤的浸潤狀態和連續植被，不僅解決了覆蓋免耕制中有機質分解、轉化慢的問題，而且使輸入土壤的有機質分解、轉化更加迅速，所以在促進土壤有機質循環方面自然免耕製表現出明顯的優越性，土壤有機質遂表現為快速的增長。
  2. When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer

    2 ）耕作制下紫色土的產流主要機制是： 1 ）當雨前土壤含水量未達到飽和狀態時，表面產流起始時間有明顯滯后現象，這與紫色土的快吸水性和較多非毛管孔隙密切相關；當雨前土壤較乾燥，降雨初期雨強較大時，易形成臨時相對不透水表層，表面產流峰也有明顯滯后現象。 2 ）表面徑流的產流方式主要是超滲產流，當土壤達到飽和狀態后，有四川大學博士學位論文小部分回歸流發生，但主要是飽和超滲產流發生，因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產流，與降雨過程有明顯的滯后，而且雨停后的壤中流產流歷時與降雨特徵無關。
  3. China agricultural university established an experiment plots in high land of fengning country, hebei province and observed the natural wind erosion. it indicated that, compared with traditional tillage - plowing up the soil in autumn, conservation tillage can reduce 77 % of soil wind erosion. it is necessary to research systematically and comprehensively on farmland wind erosion in order to study further about the effects and mechanism of conservation tillage and to explore the measures of preventing soil wind erosion

    中國農業大學在河北豐寧壩上建立農田實驗區，進行自然風蝕觀察，表明與傳統耕作（秋翻地）相比，保護性耕作可以減少土壤風蝕量77 ，進一步研究保護性耕作的防風蝕效應和機理，探索防治土壤風蝕的措施，需要對農田風蝕進行系統而全面的研究。
