精确定量栽培技术对水稻生长及产量影响

Effect of Precise and Quantitative Cultivation on Rice Growth and Yield

水稻精确定量栽培技术通过前氮后移,合理调整基蘖肥与穗粒肥施用比例,能够达到增产增效的结果。研究表明:采用茎蘖肥与穗粒肥6:4的比例,提高了有效分蘖,较常规生产增加水稻产量,单位面积增幅达13.3%,增效163.5元/667 m2。

Rice precise and quantitative cultivation can increasing production and efficiency by the techniques of postponing nitrogen fertilizers, adjusting proportion of the basal-tiller fertilizer and panicle fertilizer reasonably. The result indicated that when the proportion of the basal-tiller fertilizer and panicle fertilizer was 6：4, it can increase rice yield increase rice yield than general production, growth rate of per unit area can achieve 13.3% and increase efficiency were 163.5 yuan/667 m^2.
