順坡耕 的英文怎麼說
中文拼音 [shùnpōgēng]
順坡耕
英文
straight plowing-
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。4. at 8 ? slope land areas, the sequence of increasing production benefit of different cultivation is : mulching > plastic mulching > furrow and ridge tillage > traditional product
在黃?土地區的8坡地上,不同耕作措施對小麥的增產效益按大到小的順序是:覆蓋覆膜等高溝壟直線坡。The results show that ( 1 ) the system of contour dams, contours and fallow had positive impact on water and soil losses than grass stripes and contour ditch. at the same time it was showed that contour dams, contours, fallow significantly reduced soil erosion and water loss, grass stripe and contour ditch had recorded reduction in water and soil losses although to a much less extent than above 3 farming systems. most of sediment was bed load in all the systems except in contour dams and contour fanning
研究的主要結論如下: 1 、運用坡面徑流小區法系統地研究了當地農業生產活動中不同農作措施下紅壤坡耕地水土流失特徵、土壤養分流失規律及形態特徵,結果表明: ( 1 )同順坡農作措施相比:其它農作措施均具有明顯減輕水土流失的作用,等高土埂,等高農作、休閑處理控制水土流失的效果優於水平草帶和水平溝處理。Farming on this type of land, farmers generally plant their crops up and down the slope, and cultivate the soil with minimal concern for soil erosion
在這種土地上耕種,農民通常是順坡自上而下種植作物,而且在耕地時很少考慮土壤侵蝕。分享友人
