冀中南地区马铃薯种薯大小对商品薯产量的影响

Influence of Seed Tuber Size on Commercial Potato Production in Central-south Hebei Province

试验以5～35 g大小的费乌瑞它脱毒马铃薯种薯为材料,研究了冀中南地区不同种薯大小对商品薯产量的影响。结果表明：不同重量的种薯播种产量之间存在显著差异,以种薯重量为20~25 g的小型种薯株高平均值最大,产量最高;整薯播种比切块播种产量增加,增产幅度为1.2%~26.7%。冀中南地区生产商品马铃薯,应采用重量为20~25 g左右的小整薯作为种薯,可以获得较高的产量。

The seed tuber size of 5~35 g of cv.Farorita was studied for its effects on commercial potato production.Significance was found among various treatments,with the treatment of 20~25 g seed tuber being the highest in plant height and tuber yield.The whole seed was higher in the yield than that of the seed piece,with yield increased by 1.2%-26.7%.It was recommended that whole seed of 20~25 g be planted in Central-south Hebei Province for commercial potato production in order to get high yield.
