A Study of Effects of the Concrete Mulch on Movement of Soil Water and Soil Heat Transfer. 硬覆盖对土壤水热传输及作物生长发育影响的试验研究。
The trial test indicated that NTS was unfavorourable for seed emergence and the soil heat flux was lower than the other tillages obviously. 试验表明，免耕覆盖的土壤温度不利于豌豆的出苗，且土壤热通量明显小于其它耕作方式。
The surface energy is not balance in grassland and Gobi.In grassland the sum of LE, Hs and soil heat flux is smaller than RN. 在山区草原，晴天潜热通量是土壤热通量的三倍多，感热通量与土壤热通量差异很小，净辐射主要用于蒸发、蒸腾；
The difference between RN and sum of LE, Hs and soil heat flux on a cloudy day is bigger than that on a clear day as well as it in Gobi is bigger than that in grassland. 两地均存在能量不平衡现象，草原感热、潜热、土壤热通量之和小于净辐射，戈壁感热、潜热、土壤热通量之和大于净辐射，戈壁能量不平衡大于草原。
The results indicated that RN and LE flux in grassland is higher than that in Gobi, and Hs and soil heat flux in Gobi is higher than that in grassland on a typical clear day in summer. 结果表明，在夏季典型晴天，山区草原的净辐射、潜热通量大于戈壁，而感热、土壤热通量小于戈壁；
One of the agronomic crops that was used to determine the effects of soil heating was grass. 牧草是经常用来测定土壤加热影响的一种农作物。
A glass-covered bed of soil heated with fermenting manure or by electricity, used for the germination of seeds or for protecting tender plants. 温床有草覆盖的土层，通过发酵肥料或通电加热，用于种子的发芽或保护植物幼苗
A glass - covered bed of soil heated with fermenting manure or by electricity,used for the germination of seeds or for protecting tender plants. 温床有草覆盖的土层，通过发酵肥料或通电加热，用于种子的发芽或保护植物幼苗
Some plants push their roots deep into the soil. 一些植物的根深深长入土中。
Such crops won't grow in limy soil. 这类作物不能在石灰质的土壤中生长。
What shall we grow in this alkaline soil? 我们应该在碱性土壤里种什么？
There are a lot of worms in the soil. 泥土中有许多蠕虫。
Water has permeated (through) the soil. 水已渗遍那片土壤。

This kind of soil contains much alkali. 这种土壤含碱丰富。
She makes her living from the soil. 她以务农为生。
Grass will not succeeded in this dry soil. 在这种干燥土壤中草不会成活。
The soil absorbs only a fraction of the rain that beats down. 土壤只吸收猛打到地面上的雨水的一部分。
The soil becomes more and more acidic as pollution mounts up. 随着污染的加剧，土壤的酸化越来越严重。
