摘要
通过综合高产试验和机插行株距规格与氮肥组合试验,分析了苏粳815高产形成的特点,明确了其高产产量结构及其形成的主要生育指标,提出了目标产量650~700 kg/667 m^2相配套的精确定量栽培技术。
Through comprehensive productive test and planting density and nitrogen fertilizer combination test, the characteristics of high yield formation of machine transplanted rice were analyzed, using rice cultivar Sugeng 815 as material. The high yield components, growth characteristics, tiller dynamics, LAI, dry matter accumulation and so on were clarified. Corresponding precise and quantitative cultivation technique for 650-700 kg/667 m2 of Sugeng 815 were summed up in this paper.
