The paper, according to the laboratory stimulation of water movement in soils during freezing, analyzed formation and affecting factors for frozen stagnant water. In light of the fact that water content obviously increased after freeze. The authors advanced technical measures for afforestation in arid regions, aiming to using this part of water to assure plant’s survival and growth.展开更多

文摘In the areas of seasonal and perennial frozen soil, soil layers always contain different exent free stagnant water and frozen stagnant water, which may save the pressing need of water for spring plants. The paper, according to the laboratory stimulation of water movement in soils during freezing, analyzed formation and affecting factors for frozen stagnant water. In light of the fact that water content obviously increased after freeze. The authors advanced technical measures for afforestation in arid regions, aiming to using this part of water to assure plant’s survival and growth.
