Abstract
t was carried out to optimize combination scheme experiment of three factors among level-border specifications, irrigation quota and fertilizer methods under the condition of level-border and plastic film irrigation for corn in the sand of soil by cross experiment methods. The result indicates that the main factor affecting corn production is irrigation quota, fertilization methods; a secondary factor is level-border specifications. According to variance analysis of corn physiological characteristics and yield, the optimum combination scheme of the three factors is at level-border specifications 0.133 hm2, irrigation quota 1050 m3/hm2 and fertilization methods that is one-off hole postponed fertilizer through analysis of physiological properties and yield for corn.
