摘要: 试验针对辽宁省绥中县目前马铃薯种植生产中存在的具体问题而设计实施。调查了收获期不同施肥处理马铃薯的地上和地下产量,测定了不同施肥处理马铃薯的地上和地下养分含量,分析了不同施肥处理对马铃薯产量的影响,不同施肥处理马铃薯的干物质累积和养分累积特征,对比了不同施肥处理马铃薯收获指数和1000kg产量需肥量。结果表明,施肥水平为937.5kg/hm2的马铃薯产量最高,比常规施肥增产17.8%;其干物质累积量、N素累积量、P素累积量也都最高,但其N收获指数、P收获指数、K收获指数却低于750kg/hm2和1125kg/hm2处理,说明这一处理最大可能的生产出了较多的碳水化合物;高肥量处理每生产单位数量的马铃薯要付出更多的肥料成本,当地马铃薯生产的适宜肥料投入量应界定在750~1125 kg/hm2。

Abstract: The purpose of the experiment is solving the practical problem of potato planting. We have investigated the potato overground and underground yield of different fertilizer rates, have measured total N, total P and total K of the potato overground and underground on different fertilizer rates, have analyzed the effect of different fertilizer rates on the yield of potato and the characteristics of the accumulation about dry matter and nutrition, have compared the harvest index and the needed fertilizer per 1000kg yield. Result,The fertilizer rate of 937.5kg/hm2 could get the highest yield. It increased 17.8 percent of yield than ck. Its accumulation of dry matter, N and P is also the highest, but the harvest index of N, P and K is smaller than of 750kg/hm2 and 1125kg/hm2. Indicated that the treatment produced more carbonhydrate. More fertilizers could not produced more yield if fertilizing too much. The fertilizer of 750-1125 kg/hm2.
