我场从1968年开始,连续7年进行土豆散藏夏播留种。获得了很好的效果。种薯经过散藏。打破了休眠期.淀粉转化成糖.长出短壮芽,播后成活率高.从而提高了产量和种性。早熟品种“男爵”在没有实行散藏夏播留种前.每年用黑龙江种薯春播,亩产2,000～2,600斤。二水子亩产仅1,000～1,500斤。而用散藏夏播种薯春播,亩产都在2,600斤左右。

My field from 1968 onwards, for 7 consecutive years of potatoes scattered summer planting sowing. Obtained good results. Seed potatoes after bulk storage. Breaking the dormant period.Starch is converted into sugar.When the short strong buds grow, the survival rate is high after sowing, thus improving the yield and species. The precocious variety Baron was planted in summer before planting in summer and was planted in spring in Heilongjiang Province with a yield of 2,000-2,600 kg per mu. Two water yield per mu only 1,000 to 1,500 pounds. However, the summer planting scattered with summer sowing potato, per mu are about 2,600 pounds.
