| Abstract: | The western area of 1oss plateau of China,including the area of GansuProvince,Ninxia Hui Autonomous region and Haidon district of QinghaiProvince, lies in the arid and semi-arid climatic zone. The soil moisturegenerally is the state with low storage and low usability,all kinds of landremainds moisture potentiality in soil usable to the crops on the ground indifferent extent.The way to raise the use ratio of soil moisture is to adjustthe variety structure in the area of farming,forest and grass,to raise theground temperature in effective method,to raise the level of fertilizer ap-plication,using fertilizer to transform water,to develop larger mixed forestwith arbor tree and brush and to change the tillage style. |
