| 摘 要： | 通过毯苗栽插侧深施肥一体机进行大面积水稻侧深施肥示范,共设置8个处理,旨在探明水稻侧深施肥方式的增产效果和存在问题,提出今后机插稻合理的施肥方法。结果表明,采用毯苗机插侧深施肥平均可减少施用总氮量、总磷量分别约21.3%、26.4%,减少施肥次数1~2次;侧深施肥时水稻分蘖发生起步较早,具有明显的早发优势,较对照早发棵3~5 d;侧深施肥处理能增加水稻有效穗数、穗粒数、结实率,而千粒质量表现不一。

| Abstract: | Aiming at establishing an effective fertilization method for rice seedling transplanting in the future,this research investigated the effect of rice side deep fertilization on its yield and identified the existing problems of this technology.By using a machine that integrates the transplanting of blanket-type rice seedlings with side deep fertilization,this fertilization mode was adopted in a field trial conducted on eight experimental sites spanning a large area,which constituted eight treatments.As a result,by using side deep fertilization technology during the mechanical transplanting of blanket-type seedlings,the average application rate of total nitrogen was reduced by 21.3%,the average application rate of total phosphorus was decreased by 26.4%,and the number of fertilizer applications was reduced by one or two times.Furthermore,rice tillering occurred earlier with side deep fertilization than with the conventional fertilization;therefore,the former had an obvious advantage of early tillering,about 3~5 days earlier than the control.Also,effective panicle number,grain number per panicle,and seed setting rate of rice all increased with the deep side fertilization method,but its effect on 1000-grain weight varied among different treatments. |
