摘要
在醴陵和南县采取田间小区试验方式,研究了AGROTAIN~肥料对中季水稻产量及利用效率的影响。结果表明:施用AGROTAIN~肥料可以缩短中稻的生育期,提前1～3 d成熟;可有效降低中稻的株高及剑叶长,促进水稻稳健生长,减少倒伏风险;施用AGROTAIN~肥料后,超级杂交中稻增产4.89%～9.44%,常规优质中稻增产2.76%～5.96%,并提高了中稻氮肥偏生产力、氮肥农学利用效率、氮肥表观利用率。
Field plot experiments were conducted in Liling and Nanxian County to study the effects of AGROTAIN^■fertilizer on yield and utilization efficiency of mid-season rice.The results showed that application of AGROTAIN?fertilizer could shorten the growth period of mid-season rice and advance its maturity by 1-3 days.It can effectively reduce the plant height and flag leaf length of mid-season rice,promote the stable growth of rice and reduce the lodging risk.After applying AGROTAIN^■fertilizer,the yield of super hybrid mid-season rice increased by 4.89%-9.44%,and that of conventional high quality mid-season rice increased by 2.76%-5.96%.The partial productivity,agronomic utilization efficiency and apparent utilization efficiency of nitrogen fertilizer in mid-season rice were also improved.
