摘要
2008年以千重浪为试验品种研究稻曲病病粒数多少对水稻产量损失和病穗产量结构的影响。结果表明,稻曲病的发生对每穗总粒数及离病粒较远的健粒影响较小,病粒的多少与单穗实粒重、产量损失率有较大的相关性,病粒的存在强烈影响着接近主轴粒的健粒千粒重,并使病穗空秕率上升,千粒重下降,最终影响水稻产量。
The effect of false smut ball number on yield loss and yield components was studied in 2008. The results showed that the infection of false smut less affected spikelet number, but greatly influenced on grain weight per panicle, yield loss rate and 1000-grian weight close to panicle axis and led to decrease of yield.
