马铃薯原产南美洲较冷凉的高山地区。是一种产量高、用途广的块茎作物。我区各族人民在冬春两季都以此作为主要蔬菜之一。但在干旱平原地区种植,产量一直低而不稳,这就造成远途调运来解决种蓄和食用问题。 为提高单位面积产量,改革马铃薯栽培技术,一九七九年我们在五家渠开展了马铃薯滴灌平栽的试验研究,并取得了可喜的成果。滴灌平栽马铃薯较传统沟灌垅栽增产89.6％;每亩用水量比沟灌节省47.6％,为干旱平原地区马铃薯栽培技术摸索了经验。现将试验研究结果分述于后: Potato native to the colder alpine regions of South America. It is a high-yield, versatile tuber crop. People of all nationalities in our region take this as one of the main vegetables in winter and spring. However, cultivation in the arid plains has been low and unstable, which has led to long-distance transport to solve the problem of planting and consumption. In order to increase yield per unit area and reform potato cultivation techniques, we conducted a pilot study on flattening and drip irrigation of potatoes at Wujiaqu in 1979 and achieved gratifying results. The drip irrigation planted potatoes increased the yield by 89.6% compared with the traditional furrow irrigation; the water consumption per acre was 47.6% less than the furrow irrigation, which explored the experience of potato cultivation techniques in arid plains. Now the experimental research results are described later:
