摘　　要：为了探讨不同栽培措施下施肥对马铃薯生长的影响,2013年在金沙县安洛乡、玉屏县朱家场镇、荔波县朝阳镇、黄平县浪洞乡各选高、中、低肥力水平的地块,进行不同种植模式下的马铃薯肥效试验。结果表明:不同种植模式下缓释肥处理的产量和净产值均高于配方肥处理;与垄作不覆膜栽培相比,免耕覆膜栽培下的马铃薯生长发育良好,分枝数增加,农艺性状得到有效改善。免耕覆膜栽培下的缓释肥区和配方区的平均产量比对照区分别增产65.49%和54.01%,比垄作不覆膜栽培相应处理分别增产9.36%和3.94%。因此,在马铃薯栽培管理中,种植模式可采用免耕覆膜栽培方式,并根据土壤肥力水平合理施用缓释肥。To study the influence of different cultural practices on potato growth,test sites were chosen from lands of high fertility, moderate fertility and low fertility in Anluo Village （Jinsha County ）, Zhujiachang Town（Yuping County）,Chaoyang Town（Libo County）and Langdong Village（Huangping County）in 2013, then fertilization experiments with potato under different planting patterns were conducted.Results：The yield and net output value of slow-release fertilizer area were higher than formula area under different planting patterns.Comparing with ridge tillage and no mulch,no-tillage mulching potato grew and developed well and increased the number of branch,then agronomic characters of potato were improved effectively.Comparing with control area,slow-release fertilizer area and formula area with no-tillage mulching increased by 65.49% and 54.01% respectively.Comparing with the corresponding processing of ridge tillage and no mulch,they increased by 9.36% and 3.94% respectively.In the potato cultivation management,therefore,no-tillage mulching mode could be adopted,and slow-release fertilizers could be applied reasonably according to the soil fertility level.
