- A Study of Effects of the Concrete Mulch on Movement of Soil Water and Soil Heat Transfer. 硬覆蓋對土壤水熱傳輸及作物生長(cháng)發(fā)育影響的試驗研究。
- The trial test indicated that NTS was unfavorourable for seed emergence and the soil heat flux was lower than the other tillages obviously. 試驗表明，免耕覆蓋的土壤溫度不利于豌豆的出苗，且土壤熱通量明顯小于其它耕作方式。
- 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. 在山區草原，晴天潛熱通量是土壤熱通量的三倍多，感熱通量與土壤熱通量差異很小，凈輻射主要用于蒸發(fā)、蒸騰；
- 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. 兩地均存在能量不平衡現象，草原感熱、潛熱、土壤熱通量之和小于凈輻射，戈壁感熱、潛熱、土壤熱通量之和大于凈輻射，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. 結果表明，在夏季典型晴天，山區草原的凈輻射、潛熱通量大于戈壁，而感熱、土壤熱通量小于戈壁；
- One of the agronomic crops that was used to determine the effects of soil heating was grass. 牧草是經(jīng)常用來(lái)測定土壤加熱影響的一種農作物。
- A glass-covered bed of soil heated with fermenting manure or by electricity, used for the germination of seeds or for protecting tender plants. 溫床有草覆蓋的土層，通過(guò)發(fā)酵肥料或通電加熱，用于種子的發(fā)芽或保護植物幼苗

- The earth in the garden is good, soft soil. 花園里的泥土松軟肥沃。
- This kind of soil contains much alkali. 這種土壤含堿豐富。
- She makes her living from the soil. 她以務(wù)農為生。
- Grass will not succeeded in this dry soil. 在這種干燥土壤中草不會(huì )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. 隨著(zhù)污染的加劇，土壤的酸化越來(lái)越嚴重。
