摘要
本文分析了秧龄、栽插密度和施肥量对８７６４１产量及其主要农艺性状的效应。结果表明，在合肥地区５月上旬播种，单苗栽插，其适宜的秧龄、栽插密度和施肥量分别为３０天、１３．３×１５．６或１３．３×１８．９ｃｍ和每亩１０ｋｇ纯氮。理想的德粒结构是：亩有效穗２３万左右，平均每穗粒数１１０～１２０粒，结实率８３％以上，千粒重２６．０ｇ左右，亩产可达５５０ｋｇ以上。
According to the experimental results, 30-day seedling age,13.3×15.6 or 13.3 ×18.9cm spacing and 150kg N/ha fertilizer amount should be employed if 87641 is sowed in early May tri Hefei Anhui with one seedling (not including tillers)per hill.Its yield can reach 8.25t/ha or above as it gets an ideal panicle-grain structure-3.45 million effective panicles or so per ha,and each panicles bearing 110- 120 spikelets with above 83 % seed-setting rate and 26 grams 1000-grain weight.
