摘要：

通过大田试验,研究了不同硝基肥品种对马铃薯生长发育、产量及品质的影响。结果表明,在氮磷钾等量的条件下,施用硝硫基复合肥和硝氯基复合肥较氯基复合肥、硫基复合肥能明显地促进马铃薯生长发育,增加单薯重、单株重以及肥料利用率。与硝氯基复合肥、硫基复合肥和氯基复合肥处理相比,施用硝硫基复合肥处理的马铃薯增产率分别为2.96%~3.06%、5.19%~5.51%和10.05%~10.37%;同时能够改善马铃薯的果实品质,增加果实的淀粉、可溶性糖和Vc含量,是较为理想的复合肥。

摘要：

In this paper,field experiments were conducted to study the effects of different nitro-compound fertilizers on yield and quality of potato with same N application rate.The results showed that compared with Cl-based fertilizer and S-based fertilizer,application of nitrate of S-based compound fertilizer and nitrate of Cl-based compound fertilizer were effective to promote the growth of potato and increase yield and nitrogen utilization efficiency.The yields of potato when applied nitrate of Sbased compound fertilizer increased 2.96% ~ 3.06%,5.19% ~ 5.51% and 10.05% ~ 10.37% respectively compared those when applied with nitrate of Cl-based compound fertilizer,S-based fertilizer and Cl-based fertilizer.Moreover,application of nitrate of S-based compound fertilizer were also effective to improve the quality of potato,increase the fruit content of starch,soluble sugar and Vc,while have no significant influence on the nitrate content of fruit.
