- Ralph is equally astute in machinery and crop management. 拉尔夫在作物和机械经营方面都同样聪明。
- The thy matter weight per unit, thy matter accumulation per stem (panicle), and transportation of leaf apparent matter was more than the high yield crop management. 与传统高产栽培管理比较，单位面积干物重、单茎物质积累量和叶片的物质表观转出量高。
- At the same site in Indonesia, the amount of runoff was affected by the soil and crop management and fertilizer inputs(Table 3). 在印尼的同一试验点，径流量也受土壤和作物管理和肥料投入的影响（表3）。
- For all the soil and crop management treatments, the total runoff decreased with increasing amounts of fertilizer inputs. 对土壤和作物管理的所有处理来说，总径流量随肥料投入量的增加而降低。
- The assumption that established recommendations for soil and crop management will always be correct simply fails to account for the diversity and dynamics of biological systems. 认为土壤和作物管理推荐一旦建立就一成不变是不能说明生物系统的多样性和多变性的。
- Possibly it is due to the integrated effects of crop management practices such as N distribution at different stages and tillering controlling methods used on different soils. 这可能是因为不同土壤上采用的作物管理措施的综合效益，比如不同生育期氮肥分配和分蘖控制方法等的差别。
- It must be emphasized that performance of inoculant and the amount of N legumes derive from BNF is directly linked to crop management including application of N fertilizer. 必须强调的是，接种物的表现和豆类作物从生物固氮获得的氮量与包括施用氮肥的作物管理直接有关。
- The results showed that high nutrient use efficiency could also be obtained at high fertilizer input level when the comprehensive crop management techniques have been developed. 从区域、农户和吨粮田不同层次上的分析表明，高投入下可以实现高效率，关键是提高综合管理的科学水平；
- The dry matter weight per unit, dry matter accumulation per stem( panicle), and transportation of leaf apparent matter was more than the high yield crop management. 与传统高产栽培管理比较,单位面积干物重、茎物质积累量和叶片的物质表观转出量高。
- Twelve treatments, a complete factorial combination of four soil-crop management practices and three fertilizer inputs, were tested at this site. The treatments involve soil and crop management and fertilizer inputs. 这一地点采用12个处理，4种土壤-作物管理措施和3种肥料投入量的全因子设计。处理包括土壤-作物管理与肥料投入。
- Better soil and crop management practices through fertilizer application a so slow down the velocity of the water runoff giving more time for the overflow to infiltrate into the soil. 通过施肥达到良好的土壤和作物管理措施也降低地表水的径流速度，从而使地表径流入渗时间延长。
- Among the soil and crop management treatments, alley cropping gave the lowest soil loss, which was only about 14% of the farmers' practice(residues burnt). 在土壤和作物管理的不同处理中，巷带种植使土壤流失量最低，只有农民习惯措施（烧掉植物残体）的14%25左右。
