研究了覆膜、滴灌和膜下滴灌三种栽培方式对云南春作马铃薯生长及产量的影响,结果表明:滴灌栽培出苗率和大薯率高,产量可达3 557.59 kg/666.7m2,比对照增产58％,增产效果和经济效益显著；而覆膜和膜下滴灌栽培方式由于导致土温较高出现烂种,使出苗率降低,同时覆膜促进了茎叶生长,降低了收获指数,造成显著减产.所以,滴灌栽培方式能有效地解决云南春马铃薯早期干旱问题,可以推广应用,但针对云南气候特点的春作覆膜栽培方法有必要进一步研究.%The influence of cultivation patterns of plastic film mulching, drip irrigation and drip irrigation underneath mulching film on the growth and yield of spring-sowing potato in Yunnan was studied. The results indicated that under the drip irrigation potato sprouted early, the rates of seedling emergence and the big tubers were high, and the yield reached 3 557.59 kg/666.7m , increasing by 58% compared with control. The yield and economic benefit increased remarkablely. Due to higher soil temperature in methods of plastic film mulching and drip irrigation underneath mulching film, it had lower rate of seedling emergence because of rotten tuber; meanwhile the plastic film mulching could promote the growth of stems and leaves, decreased the harvest index, resulting in yield decrease. Drip irrigation proved an effective cultivation pattern to solve the drought problem in the early period of potato planting, which could be applied, while the ideal cultivation pattern of film mulching for spring potato in Yunnan needs further study.
