为了探讨在固原自然条件下培养地力及提高洋芋产量的新路子,1983年我们在上黄村进行了洋芋高垄地膜覆盖和间作黄豆试验,为大面积推广提供科学依据。一、试验处理本试验以高垄栽培为基础,设高垄播后覆膜(盖白色地膜,现蕾期揭膜);高垄不覆膜两种处理,平作为对照。垄高1.5尺,宽3.0尺,沟宽3.0尺,垄上挖穴点种洋芋,沟内套种黄豆,洋芋及黄豆种植比例1:1。每垄种植三行,小区面积0.1亩,重复三次;试验面积共1.2亩。试验地分别设在上黄村的河谷和塬地上。前茬为麦茬,伏耕一次,秋耕二次,亩
In order to explore the new way to cultivate the fertility and improve the yield of potato in the natural conditions of Guyuan, we carried out the experiment of covering the potato with high ridge with high ridge in Shanghuang Village in 1983, which provided a scientific basis for the large-scale promotion. First, the experimental treatment In this experiment based on high ridge cultivation, set up after the high ridge cover film (cover white film, budding period film); high ridge without coating two treatment, flat as a control. Ridge height of 1.5 feet, 3.0 feet wide, 3.0-meter-wide ditch on the hole digging points of potato, ditch interplanting soybean, potato and soybean planting ratio of 1: 1. Each ridge planting three lines, the plot area of 0.1 acres, repeated three times; a total area of 1.2 acres test. Experimental sites were located in Shanghuangcun valley and plateau. The former crop is stubble, Fuber once, autumn plowing twice, mu
