摘要
研究旱作条件下不同播期对谷子产量和主要农艺性状的影响,探索黑龙江一、二积温带谷子种植最适播期。通过2013~2014两年播期试验,得到不同播期间在穗长、穗粗、穗重、千粒重及产量上发生较大的变化,不同播期间产量差异达到了极显著水平。结果表明,黑龙江省第一、二积温带龙谷31最适播期为5月17日,对低温敏感,吨谷1号需要适时早播,对低温不敏感。黑龙江一、二积温带最适播期在5月15日至5月20日之间。
The effects of different sowing dates on the yield and the main agronomic traits of foxtail millet were studied in order to explore the suitable sowing date in the first and second accumulated temperature zone of Heilongjiang province. The results of field experiment in 2013-2014 showed that the ear length, ear diameter,ear weight, 1000 grains weight and grain yield had the different changes among different sowing dates,and there were extremely significant difference on grain yield among different sowing dates. The optimum sowing date of Longgu31 was May 17,and had the low temperature sensitivity. Dungul need to be sowed early at the right times,had the low temperature insensitiveness. The suitable sowing date was from May 15 to May 20 in the first and second accumulated temperature zone of Heilongjiang province.
