摘　　要：试验通过机插稻与直播稻群体质量分析比较,研究分析了机插水稻增产机理。结果表明,机插稻具有群体生长平稳,高效叶面积高,抽穗后叶的衰减速度慢,干物质积累高,成穗率高,穗大粒多优势明显,并据此提出了关键栽培技术措施。The test was carried out on the comparative analysis of population quality of machine transplanting and direct seeding rice to research the yield increase mechanism of the former. The results showed that the population of machine transplanted rice grew more stable, had larger area of efficiency leaves, and slower decreasing rate afler heading, high dry matter accumulation and percentage of ear-bearing tillers, and obviously bigger panicles and more grains per spike, so the main high-yield cultivation was presented.
