裸土和草地的净长波辐射最大值出现在夏季，而森林和农田则出现在冬季。

The maximum of net long-wave radiation over bare and grass appeared in summer , but in winter over tree and crop .

含游离碳酸钙的菜园土、石灰土的净吸持量约是第四纪红色粘土、黄壤的3.0～6.5倍。

Both of vegetable soil and calcareous soil contain CaCO_3 , and the net retention capacity of them was about 3.0-6.5 times as that of Quaternary period red clay or yellow soil .
