摘  要:为探究钙[Ca(NO_(3))_(2)·4H_(2)O]、锌(ZnSO_(4)·7H_(2)O)肥滴施对马铃薯生长、产量及品质的影响,以新大坪原原种为材料,采用膜下滴灌技术,分别设置3种不同钙、锌施肥量处理。结果表明,钙肥滴施处理的马铃薯产量较高,马铃薯块茎单株大中薯数、单株大中薯质量、单株薯质量均比CK显著增加,其中T1(150 kg·hm^(-2))处理产量达67 619.05 kg·hm^(-2),马铃薯块茎蛋白质、粗淀粉、锌含量均比CK极显著提高;锌肥滴施处理马铃薯植株生长较好,品质较高,其中T6(45 kg·hm^(-2))处理产量达70 555.56 kg·hm^(-2),马铃薯块茎钙含量均比CK极显著提高。综合分析,钙肥施入量为150 kg·hm^(-2)、锌肥施入量为45 kg·hm^(-2),马铃薯植株生长期农艺性状较好,块茎产量较高,品质较优。To explore the effects of calcium [Ca(NO_(3))_(2)·4H_(2)O] and Zinc(ZnSO_(4)·7H_(2)O)fertilizer drip irrigation on potato growth, yield, and quality, In this study, three treatments with different amount of calcium and zinc fertilizer were set on the original seed of Xindaping using drip irrigation under the membrane. The results showed that the potato yield of calcium fertilizer drip irrigation was better, and the number of large and medium potatoes per plant of potato tuber, the weight of large and medium potatoes per plant and the weight of potato per plant were significantly increased compared with CK.The yield of T1(150 kg·hm^(-2))was 67 619.05 kg·hm^(-2), and the contents of protein, crude starch and zinc of potato tuber were significantly higher than those of CK. The yield of T6(45 kg·hm^(-2))reached 70 555.56 kg·hm^(-2), and the tuber calcium content was significantly higher than that of CK. Comprehensive analysis showed that the application amount of calcium fertilizer was 150 kg·hm^(-2)and zinc fertilizer was 45 kg·hm^(-2), which resulted in better agronomic characters, higher tuber yield and better quality in the growing period of potato plants.
