稀土元素使大豆增产效应初析

Primary Analsis of Reason for Soybean output Increased by Treatment with Rare-Earth Element

Raer--earth element of appropriate concentration (50mg/kg seed+ 50mg/kg soil)was mixxed with seed and soil repectively, which makes soybean output increased. This phenomenon mainly results from stimulating nodulation and enhancing activity of nitrogenase.
