Abstract:Affect of soil texture and rotation on wheat yield and water use efficiency has studied by using the method of contrast in Linfen and Xiangfen,Shanxi province.The result showed that the wheat has get more yield in fallow for rotation in light loamy soil and in nonfallow for rotation in mediate loamy soil,and the soil has more store water before sowing in fallow for rotation in light loamy soil and in nonfallow for rotation in mediate loamy soil.Water consumption over growth stage under the ground 0~100 cm,0~200 cm and 100~200 cm in light loamy soil is fallow for rotation>soybean for rotation>mung bean for rotation,both store water at jointing stage and water consumption at jointing and maturation stage under the ground 0~100 cm,0~200 cm and 100~200 cm in mediate loamy soil is peanut for rotation>millet for rotation>fallow for rotation.The mediate loamy soil has higher water use efficiency and bigger range among every rotation.The study has provided academic evidence to select soil texture of sequential summer crops,and spring crop rotation for the rotate system relying mainly on nonirrigated wheat.
