摘要
通过不同刈割次数对一年生黑麦草A2003种子产量影响试验,结果表明,2次刈割A2003黑麦草种子产量最高,达963.45 kg/hm2。刈割处理可促进A2003黑麦草分蘖,提高有效株数和穗数,延长生育期。
A2003, a new Lolium multiflorum line, was tested to study effects of different mowing times on its seed yield. The results showed that the highest seed yield with twice mowing was 963.45 kg/hm^2 and mowing could raise its fresh grass yield and seed yield by improving its tillering ability, effective plants and ears, and prolonging its growth period.
