坡耕地起垄和埋设地槽对土壤水分和马铃薯产量的影响
Effect of contour ridging and geosynclinal in furrow on soil moisture and yield of potato
摘要
Abstract
The field experiment of water-harvesting modes was conducted in Loess Plateau by planting potato with five treatments :(1 ) contour ridging ;(2 ) contour ridging + film mulching on ridge ;(3 ) contour ridging + geosynclinal in furrow ;(4 ) contour ridging + film mulching on ridge + geosynclinal in furrow ;and (5 ) the control .Through the analysis of soil moisture content ,soil temperature and crop yield ,it was shown that the technology of ‘contour ridging +film mulching on ridge + geosynclinal in furrow ’ could reduce soil bulk density , and increase remarkably the above-ground biomass ,water use efficiency and proportion of large and middle potatoes ,therefore it was an effective water-sav-ing agricultural practice in the semi -arid area of Loess Plateau in China .关键词
