摘要
通过精制有机肥在马铃薯上的肥效试验,研究其对马铃薯鲜薯产量的影响,为该肥料在马铃薯生产上推广应用提供科学依据。试验采用单因素随机区组设计,结果表明:精制有机肥对马铃薯有明显的增产效果,就增产(产量和纯产值)幅度来说,以处理4施精制有机肥80 kg/667 m2最高,就投产比来说,以处理3施精制有机肥60 kg/667 m2最佳(投产比为1:3.46)。
Refined organic fertilizer application on potato was tested in a randomized complete block design in order to understand its effects on potato yield, which may provide the scientific base for its extension and utilization in potato production. Application of refined organic fertilizer had obvious effect on potato yield increase. In term of yield increase （yield and net income increase）, application of refined organic fertilizer at the rate of 80 kg / 667m2 gave best result, but for the ratio of net income increase to investment best result （1： 3.46） was achieved when applied at 60 kg / 667m2.
