为了比较早稻高产田不同带蘖各类穗型的经济性状,以进一步从栽培技术上协调蘖间关系,夺取更高产量,1973年我校对五块高产田(亩产852—1,078斤)的广陆矮4号穗部的经济性状进行了分析。我们将穗型分为五类,即带有效分蘖主穗,带无效分蘖主穗,早期分蘖穗,晚期分蘖穗,单身主穗。结果表明:各类穗型间除千粒重比较稳定外,每穗粒数及空壳率相差都很大。
In order to compare the economic traits of different types of tillers with different tillers in the early rice high yield field to further coordinate the relationship between the tillers and to obtain higher yield from the cultivation techniques, in 1973, I proofed a wide range of five high yield fields (852-1,078 kg per mu) Economic characteristics of Luzhao 4 spike were analyzed. We divided the panicle into five types, namely, main tillers with effective tillers, main tillers with ineffective tillers, early tillering spikes, late tillering spikes and single main spikes. The results showed that except for the 1000-grain weight, the spikelet types were quite different.
