| 摘 要： | 研究了不同播种期和播种量对百喜草种子产量的影响。结果表明，春季播种繁种，百喜草（Pensacola A33）从播种到出苗所需要积温（≥10℃）都在290-299 d.℃之间。播种早，气温低，出苗时间长；播种晚，气温高，出苗快。种子产量和种子千粒重以早播、稀播处理为优。同一播种期，30 kg/hm^2处理的种子产量大于60 kg/hm2；播种期推后种子产量下降。

| Abstract: | The effects of sowing time and planting density on seed yield of Paspalum notatum Flugge were studied.The results showed that: the accumulated temperature for seedling emergence of Pensacola A33 was 290~299 d·℃,the higher the temperature was,the faster the seed sprouted.The seed yield and weight of 1000-grain were the highest with early sowing time and large planting density.For the same sowing time,the seed yield of sowing 30 kg/hm2 was higher than that of sowing 60 kg/hm2;the seed yield dropped as sowing time delayed. |
