当前,在氮素和磷素化肥普遍且大量施用的基础上,对微量元素肥料的施用已逐步提到科学施肥的议事日程上来。根据我省酒泉、张掖等地施用锌肥防治玉米白化苗,施用锰肥使小麦等作物增产,及一些科研单位搞的稀土微肥能使作物增产的试验结果,表明在我省不同地区,因土施用微量元素肥料具有一定的增产效果。从而展示出科学施肥向纵深发展的良好前景和增产潜力。我场位于河西走廊东部,海拔高度1900米,耕地面积七千余亩,土质为灰钙土,属河西
At present, on the basis of the widespread and mass application of nitrogen and phosphorus fertilizers, the application of trace element fertilizers has been gradually referred to the scientific fertilization agenda. According to the province Jiuquan, Zhangye and other places to apply zinc fertilizer to control corn albino seedlings, the application of manganese fertilizer so that wheat and other crops, and some research institutes to make rare earth elemental fertilizer yield test results show that in different parts of our province, due to Soil application of trace element fertilizer has a certain yield increase. Thus demonstrating the scientific development of fertilizer to the depth of the good prospects and increase production potential. My field is located in the eastern Hexi Corridor, 1,900 meters above sea level, more than 7,000 acres of arable land, soil is calcareous soil, is Hexi
