- 摘要:
- 为了探讨马铃薯的适宜播期,2012年在柳州进行了马铃薯分期播种试验,研究不同播期对马铃薯生长发育、开花盛期农艺性状及产量的影响。结果表明:随着播期的推迟,马铃薯全生育期明显缩短,不同播期下,各生育阶段相差最大的是出苗期和开花始期。通过对不同播种期各个生育期气象条件的比较得出,播种-出苗期的低温寡照以及开花盛期-成熟期的高温对柳州马铃薯影响较大,综合来看2月20日左右播种马铃薯最为适宜。
- Abstract:
- In order to discuss suitable sowing date of potato,the field experiment of potato was conducted in Liuzhou in 2012 to study the effects of sowing date on the growth,development and agronomic traits in full blossom of potato.The results showed that the growth period of potato was shortening with the delay of sowing date.Seeding stage and flowering start stage had biggest difference in different sowing date.Through the comparison on meteorological conditions of each growth period in different sowing date,conclusion was obtained that low temperature at seedling stage and high temperature in blossom at maturity stage had impact on growth and development of potato in Liuzhou.In conclusion,suitable sowing date of potato was on February 20 or so in Liuzhou.
