摘　　要：采用带侧深施肥装置的水稻插秧机,在机插秧同时进行缓控释肥不同施量侧深施肥作业试验。以当地水稻生长期总施氮量为基准,设计3个缓控释肥施用标准,与常规施肥方式进行对比。结果表明:水稻机插秧同时进行侧深施肥作业,利用缓控释肥周期性释放特点,可满足水稻在生产关键节点的肥料需求,产量与常规施肥方式无明显差异,比常规方式减少施肥作业次数、节省人工、减弱劳动强度,具有可行性及地区适应性。The rice transplanter with side deep fertilization device was used to carry out the experiment of slow controlled-release fertilizer with different side deep fertilization.Three application standards of slow controlled-release fertilizers were designed based on the total amount of nitrogen applied during the whole growth period of rice in this area,and compared with the conventional rice fertilization.The results show that:Rice transplanting with machine,side deep fertilization,using the periodic release characteristics of slow controlled release fertilizer,can meet the fertilizer demand of rice in the key production nodes,and its yield is not significantly different from that of conventional fertilization.However it could reduce the number of fertilization operations,save labor,weaken labor intensity,and have feasibility and regional adaptability.
