水稻免耕抛秧栽培在不同施N量的情况下，对穗实粒数影响最大，其次为亩有效穗，对千粒重的影响最小。低N肥区低产原因为穗实粒数少，中N肥区获取高产量原因为每穗实粒比低N肥和高N肥区多。本文对水稻免耕抛秧栽培不同施N量植株的生长特点及其原因进行了初步的分析。
水稻免耕拋秧栽培在不同施N量的情況下，對穗實粒數影響最大，其次為畝有效穗，對韆粒重的影響最小。低N肥區低產原因為穗實粒數少，中N肥區穫取高產量原因為每穗實粒比低N肥和高N肥區多。本文對水稻免耕拋秧栽培不同施N量植株的生長特點及其原因進行瞭初步的分析。
수도면경포앙재배재불동시N량적정황하，대수실립수영향최대，기차위무유효수，대천립중적영향최소。저N비구저산원인위수실립수소，중N비구획취고산량원인위매수실립비저N비화고N비구다。본문대수도면경포앙재배불동시N량식주적생장특점급기원인진행료초보적분석。
objective: The cultivation of no-til age cast-transplanting rice in the situations of different amount of N applied,influencing grain number per panicle the most,the influence to number of productive ear per mu is the next,and the thousand seed weight the least.The reason for low yield of low N fertiliter area is lacking of graint number per panicle,and the reason for high yield of N fertilizer in the area is that the fil ed grains per panicle is more than the fil ed grains per panicle of low N area and high N area.This test wil presents a preliminary analysis about the plant’s growth characterisitics of the no-til age cast-transplanted rice cultivation in different amount of N applied and the reason for al of that.
