农作物施用稀土的技术和效果的研究已有许多报道,全国稀土农用面积1990年已突破3000万亩。但我区稀土农用起步晚,对春小麦等作物施用稀土的技术和效果均未进行系统研究,在实际应用中存在着较大的盲目性。本试验的目的在于明确我区春小麦施用稀土的效果,确定施用技术,为大面积推广提供依据。 There have been many reports on the techniques and effects of applying rare earths to crops. The area of ​​rare earths in China exceeded 30 million mu in 1990. However, due to the late start of rare earth farming in our district, no systematic research has been conducted on the application of rare earths to spring wheat and other crops. In practice, there is a big blindness. The purpose of this experiment is to clarify the effect of applying rare earth in spring wheat in our district to determine the application technology and provide the basis for large-scale popularization.
