土表 meaning in Chinese
soil surface
Examples
- These soils are well developed and contain a subsurface horizon in which clays have accumulated
发育良好，土表下有一层粘土淀积土层。 - The efficiency that black mulch increases soil temperature , that is , transfers heat from the mulch to the soil , can be improved by optimizing contact between the mulch and the soil surface
黑色塑料薄膜提高土壤温度的效率（即把热能从薄膜传递到土壤）可以通过使薄膜与土表最适的接触来提高。 - Description : the soil covers is not sufficient to stop erosion ; nor are the physical structures . the only solution is to find appropriate crops to produce enough residues to favour infiltration
土表覆盖不足不能够阻止侵蚀、改变土壤结构。只有寻找合适的、能够生产足够残茬的作物，才有利于水份的渗透。 - 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
虽然在少耕制下，土壤钾有明显的分层分布（象永久性草地一样） ，但在土表附近，作物根系发达保证作物对钾有足够的吸收。 - Organic matter is higher at the soil surface because plant residues from either grasslands or no - till are left on the surface whereas residues in conventional fields are mixed in the soil ; giving uniform organic matter
在草地和免耕方式下，植物残体留在土表，所以表层土壤的有机质含量较高，而在传统耕作制下，植物残体被翻入土内，所以各层土壤中有机质含量差别不大。
