摘 要: 以甘薯为材料,采用裂区设计探索了氮肥增效剂在南方热带地区的应用效果.结果表明:(1)在热带地区使用氮肥增效剂可以提高甘薯的产量,增产效果显著.(2)氮肥增效剂可以在一定程度上提高甘薯对氮、磷、钾的吸收,促进作物的生长.(3)氮肥增效剂的使用会降低甘薯还原糖的含量,对品质有一定的负面效应. The experimentation takes sweet potato stem rot for example, using split plot design for exploring the implication effect of nitrogen adjuvant in south china tropic areas. The experiment shows: ( 1 ) nitrogen adjuvant improve the production of sweet potato stem rot in tropic areas, sometimes , the influence effect is significant. (2) nitrogen adjuvant decrease the content of deoxidize sugar of sweet potato stem rot so much that it brings negative effect. (3)nitrogen adjuvant enhance the absorb of nitrogen, phosphorus, potassium for sweet potato stem rot and benefit the growth.
