| Abstract: | 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. |
