摘要
以马铃薯中熟品种克新18为试验材料,在黑龙江省西部农场进行马铃薯不同播期试验,探讨其对马铃薯生长、淀粉含量及产量的影响。结果表明:马铃薯不宜过早播种,过早易遭受低温,影响壮苗,从而影响产量及品质;黑龙江省马铃薯适宜播期为5月上、中旬,此期播种的产量高,与其它播期产量差异达极显著水平,最佳播期为5月6日,最高产量达49 555kg.hm-2,淀粉含量高达15.51%,与其它播期淀粉含量差异达极显著水平。
Taking the mid-maturing potato variety Kexin18 as experimental material,the experiment of different sowing date was conducted in Western Farm in Heilongjiang to discuss the effect on growth,starch content and yield of potato.The results showed that：the potatoes should not be planted too early,it may be vulnerable to low temperature to make the seedlings become weak,thus affecting the yield and quality;Potato suitable sowing date was in early and mid May in Heilongjiang province,which would obtain high yields,yield difference reached a significant level with other sowing dates.The best sowing date was May 6th,the maximum yield reached 49 555 kg·hm-2,starch content reached 15.51%,starch content difference reached a significant level with other sowing dates.
