  1. And the major results and some new viewpoints were presented as follow : 1 ) sediment content of cn tillage system in runoff process is substantially low compared to st under rainfall with high intensity, showing cn bear the efficient capacity of control soil loss. nevertheless, when soil is saturated, the runoff intensity of both tillage systems is near, implicating cn has the limited function of reducing runoff. 2 ) based on the case analysis of observed all rainfall - runoff generation processes, a ) the initiation time hysteresis of surface runoff generation is notable when rainfall fall upon the unsaturated purple soils, which is attributed to the property of rapid water sorption and much non - capillary porosity

    經近幾年的觀測和理論分析,取得了以下結果和創新的認識: 1 )在降雨強度較大的情況下,保護性耕作制? ?聚土免耕的產沙強度明顯較常規耕作制? ?順坡耕作的小,說明聚土免耕耕作制防治土壤流失是有效的;但當土壤達到飽和后,聚土免耕的徑流強度與常規耕作的差異較小,產沙強度也增大,因此,聚土免耕防治水土流失的能力是有限的。
  2. As a result of the work mentioned above, the usual method of phosphate fertilization for crops grown under no tillage and minimum tillage has come to be surface broadcasting

    由以上的研究我們可以得出這樣一個結論:免耕和少耕耕作制下,通常磷肥的施用方法可以採用地表撒施。
  3. With exception of soils that are cold and wet at planting time, no evidence exists that surface broadcasting of potassium fertilizer is not an adequate method of fertilization under reduced tillage

  4. Summarizing phosphorus fertilization under minimum and no tillage, it can be said that surface broadcast applications generally work very well in terms of plant uptake and for maintaining adequate soil levels of available soil phosphorus

    綜上所述,免耕制和少耕制下磷肥的施用,從植物吸收的角度和從維持足夠有效水平的角度來考慮,地表撒施一般效果很好。
  5. Because no tillage and minimum tillage reduce erosion and concentrate nutrients in the surface soil just below the residue cover, micronutrients generally are less often deficient than under conventional tillage

    由於少耕和免耕減少了水土流失,同時把養分富集在植物殘茬覆蓋下的土壤表層,所以,與傳統耕作制相比,少耕和免耕一般不易發生微量元素的缺乏。
  6. Effects of tillage practices on temporal variations of soil surface properties

    夏玉米耕作方式對耕層土壤特性時間變異性的影響
  7. 2. on the basis of analyzing experimental data for slope land of loess plateau in different slope gradient and rain intensity and soil and water conservation tillage measures, using curve - fitting techniques, a soil infiltration rates model was woke out, the accuracy of the model is tested by a series of experiment data, the result of these indicate that the soil infiltration rates model is accurate and has good stability for slope land of loess plateau. 3. using soil infiltration rates and runoff time and wetting frontal surface depth of soil infiltration reflect effect of factor affecting soil infiltration rates

    ( 3 )採用土壤穩定入滲速率、坡面開始產流時間、土壤濕潤鋒面下滲深度三個指標來反映坡耕地土壤入滲影響(土壤性質、土壤初始含水率、地面坡度、降雨強度、積水深度、水土保持耕作措施等)因素效用大小,建立了各因素與三個指標的關系模型,詳細分析了不同水土保持耕作措施強化土壤入滲的影響,其中等高耕作作用最為顯著,其次是人工掏挖和人工鋤耕。
  8. His year just at the end of the harvest, lan jie not only retained a high stubble but she also enclosed the direct seeding area with no - tillage fields with help of the local government to protect the reserved crop stubble on the surface

    今年秋收剛過,藍姐就早早做好了準備,不僅收獲時留了高茬,還在當地政府部門的幫助下,對將要實施免耕播種的田塊進行了圍封,以保護留在地表的作物根茬。
  9. It is agreed by the forum that conservation agriculture is a sustainable modern agricultural technology that covers the ground surface with straws or stubble, practices minimum tillage no - till, and uses chemicals, machines, crop rotation and other ways to control diseases and insect pests

    會議認為,保護性耕作是採用秸稈或根茬覆蓋地表,進行少免耕播種,採取化學機械輪作等不同方式控制病蟲草害發生的一項可持續發展的現代農業先進技術。
  10. The experiences of controlling sandstorm in the world indicate that, promoting conservation tillage can effectively control the raising of dust on soil surface, prevent soil from wind erosion, restrain the trend of land desertification, and ultimately, realize the purpose of controlling sandstorm

    世界各國治理沙塵暴的經驗表明,農田推行保護性耕作可以有效地控制地表土壤沙塵的揚起,防治土壤風蝕,抑制土地沙漠化的擴展趨勢,最終實現治理沙塵暴的目的。
  11. Even though potassium is stratified under reduced tillage ( as it is in a permanent sod ), it is apparent that roots proliferate sufficiently near the soil surface to assume adequate potassium uptake by crops

    雖然在少耕制下,土壤鉀有明顯的分層分佈(象永久性草地一樣) ,但在土表附近,作物根系發達保證作物對鉀有足夠的吸收。
