大西洋不同种级种薯对河西走廊马铃薯经济性状的影响

Effect of Different Class Seed Potato of 'Atlantic' on Economic Characters of Potato in Hexi Corridor

以大西洋马铃薯为试材,研究了不同种级种薯对河西走廊马铃薯经济性状的影响。结果表明:采用原种、一级种作种薯,无论在株高、单株分茎数、单株茎叶鲜重,还是在单株结薯个数与单株块茎产量上都明显优于微型薯和二级种;不同种级间原种、一级种的产量明显高于其他种级,一级种整薯产量最高,平均为51919.5 kg.hm-2,其次为原种整薯51558.0 kg.hm-2,二者之间差异不显著;同一种级整薯较切块产量高;小整薯比切块种薯有明显的生长优势,而且病害较轻、产量高。

＇Atlantic＇ was used as materials to study the effect of different class seed potato on potato economic character in Hexi Corridor. The results showed that the basic seed, lst class certisify seed potato,in terms of plant height,single plant stems quantity,stem-leaf fresh weight,single plant tubers number and yield were much better than thoes of micro tuber and seconed class certicify seed potato;the yield used basic seed, 1st class certicify seed was significantly higher than that of other classes seed potatoes. The yield was highest when using whole tuber. The yield of using whole tubers was higher than using cutting tubers,using small whole tubers have the obvious advantage of the growth and less disease, high yield than using cutting tubers.
