摘　　要：采用田间小区试验,研究微量元素硼、锌对马铃薯农艺性状、产量、品质、叶绿素含量的影响。结果表明:施用微量元素硼、锌可以明显提高马铃薯株高、单株结薯数、大中薯、单株产量、产量、淀粉含量、蛋白质含量和各生育期叶片的叶绿素含量,降低单株小薯数。推荐施肥+锌处理下,株高明显高于其它处理;推荐施肥+硼+锌处理下,单株结薯数、大中薯、小薯、单株产量、产量均明显高于其他处理。推荐施肥+硼+锌处理下,马铃薯产量达到最大值,为44 188.75 kg/hm2;淀粉和蛋白含量达到最大值,分别为16.12%和3.14 mg/g。同一生育期叶绿素含量大小为:空白对照<推荐施肥<推荐施肥+锌<推荐施肥+硼<推荐施肥+硼+锌。The field plot experiment studied the effects of trace element boron, zinc on agronomic characters, yield, quality, content of chlorophyll of potato.The results showed that ： Application of trace element boron, zinc can significantly increased The plant height, the potato tuber number, large and medium potato, yield per plant, yield, starch content, protein content and leaf chlorophyll content, decreased mall tuber number per plant. Recommended fertilization ＋zinc treatment, plant height was significantly higher than other treatments; recommended fertilization ＋ boron ＋ zinc treatment, tuber number, large and medium potato, small potato, yield per plant, yield, were significantly higher than other treatments. Recommended fertilization ＋ boron ＋ zinc treatment, potato yield reaches the maximum value, is 44 188.75 kg/hm2; starch and protein content reaches the maximum value, respectively 16.12% and 3.14 mg/g. The same growth period chlorophyll content size is： blank control 〈 recommended fertilization〈 recommended fertilization＋ zinc〈recommended fertilization＋ boron 〈 recommended fertilization ＋ boron ＋ zinc.
