摘要:

为了更好地验证添加肥料生物活化剂的氮肥肥料(简称氮肥+),在大豆生产上的应用效果,更好提高肥料利用率,研究氮肥+在大豆上应用效果,确定氮肥+在大豆生产上的最佳用量和施用方法,验证了氮肥+肥料添加的生物活化剂在氮肥中是否能够确切提高肥料利用率,提高大豆单产促进大豆生产发展提供新肥料的施用技术。在本试验条件下每公顷施85%氮肥+38.25 kg、二铵180 kg、50%硫酸钾75 kg增产效果显著,比对照增产147.75 kg/hm2,增产率为4.12%。

Abstract:

Adding fertilizer biological activating agent of nitrogen fertilizer (referred to as N+), can improve the utilization rate of fertilizers, through the study of the N+ on soybean application effect, determine the optimal dosage and application methods, validation of fertilizer biological activating agent in nitrogenous fertilizer is able to exact to increase the utilization rate of fertilizer. The results showed that in this experiment condition, 1 hm2 applying nitrogenous fertilizer+ 85% 38.25 kg, 180 kg, 50% 75 kg ammonium potassium sulfate yield significant than CK 147.75 kg/hm2, increase rate was 4.12%.
