近十几年来,根据国内外的试验和大面积使用,施用少量微量元素,对促进庄稼的生长发育、提高品质、增加产量,都有较好的效果,特别是钼肥。由于钼肥能促进固氮作用,能把根瘤菌和其他固氮微生物对空气中氮素固定能力提高几十倍至几百倍。所以增施钼肥对一般豆科庄稼都能取得10—30％的增产效果。是一种用量少、成本低,收益大和施用方便等增产增收的好办法。黑龙江
In recent ten years, according to domestic and foreign experiments and large-area use, the application of trace elements and trace elements has a good effect on promoting the growth and development of crops, improving the quality and increasing the yield, especially the molybdenum fertilizer. Because molybdenum fertilizer can promote nitrogen fixation, Rhizobium and other nitrogen-fixing microorganisms can improve the ability of nitrogen fixation in the air several tens to hundreds times. Therefore, the application of molybdenum fertilizer on the general legume crops can achieve 10-30% yield increase. Is a less dosage, low cost, large benefits and ease of application such as a good way to increase production and income. Heilongjiang
