氮肥增效剂又称联合固氮菌，对多种农作物有显著的增产效果。1992年引入当涂县后，我们首先把该试剂运用到水稻生产上，并做了不同施用浓度的比较。供试作物品种是晚粳丙664。根据试验表明，使用浓度以200PPm效果最佳i施用方法是危秧根，浸泡半小时左右，捞起晾干后栽插，在水
Nitrogen synergist, also known as the combination of nitrogen-fixing bacteria, a variety of crops have a significant yield-increasing effect. After the introduction of Dangtu County in 1992, we first applied this reagent to rice production and compared it with different application concentrations. The tested crop varieties are late Japonica 664. According to the test shows that the use of the concentration of 200PPm best i application method is the danger of seedlings, soak for about half an hour, picked up and dried planted in water
