摘要
观察不同播种期对早熟、中熟、晚熟等3个波斯菊类型采种的影响。结果表明,作为采种栽培,中熟品种的最佳播种期为6月29日前后,平均产量为495 kg/hm2左右,晚熟品种的最佳播种期为6月13日前后,平均产量为525 kg/hm2左右,而早熟品种不适宜在长江流域采种栽培。
The effects of different sowing times on harvest of early-maturing, mid-maturing, latematuring cosmos are observed. The results show that the best sowing time of mid-maturing cosmos is June 29th, and the average yield is about 495 kg/hm^2 ; the best sowing time of late-maturing cosmos is June 13th, and the yield is about 525 kg/hm^2; but the early-maturing cosmos is not suitable for planting in Yangtze River Basin.
