摘　　要：试验以早籼稻皖稻83(竹舟5号)为材料,研究播期和育秧密度对秧苗素质的影响,播期和栽插苗数对分蘖动态及产量性状的影响。结果表明:竹舟5号在安徽合肥4月6日播种,其秧苗素质较好,分蘖成穗率较高,大田栽插每穴2粒种子苗,产量较高,其他产量性状也较协调。The experiment in the influence of sowing time, seeding density and transplaning seedling number of early-season rice-Wandao 85 yield was done. The result was as follows：sowed on April 6th, the seedling quality was better than the others and the tillering rate was high. The yield of two transplant seedlings per nest was higher than the others and its yield traits were harmonious.
