| 摘 要： | 为了探讨金正大缓控释肥在湘北环湖平丘区水稻生产上增产、增收的效果,2011年在益阳市赫山区毕架山乡中档村进行了晚稻缓控释肥与有机肥、常规化肥定位效应试验。结果表明,缓控释肥前期肥效释放较快,土壤中速效N、速效K含量分别为227.33和180 mg/kg,显著高于有机肥和无肥处理,为水稻前期分蘖生长提供更充足的营养物质,且能起到改善土壤营养的作用;湘晚籼17号在不同施肥处理下产量表现为缓控释肥>有机肥>常规施肥>无肥对照。

| Abstract: | Fertilizer location experiments were carried out to investigate the effect of Jinzhengda slow-release fertilizer on increasing output and benefit of rice in plain and hilly area around lake of northern Hunan with slow release fertilizer,organic fertilizer and conventional chemical fertilizer in Bijiashan village of Heshan district,Yiyang city in 2011.The results showed that slow-release fertilizer could provide enough nutrition to plant and improve soil nutrition.The fertilizer released fast at early stage,the total content of N and K were 227.33 and 180 mg/kg in the soil.The yields of Xiangwanxian No.17 were different under different treatments: slow-release fertilizer > organic fertilizer > conventional fertilization > CK. |
