中文摘要: |
在黄土高原坡地采用(1) 沿坡地等高线起垄;(2) 沿
坡地等高线起垄,垄上覆膜;(3) 沿坡地等高线起垄,垄间带底下设地槽;(4) 沿坡地等高
线起垄,垄上覆膜,垄间带底下设地槽等4种不同的集雨方式种植马铃薯,并设置不覆膜的
大田比较试验。通过对土壤含水量,土壤温度及作物产量进行分析,发现垄上覆膜结合地槽
贮水技术,可降低土壤的容重,大大提高马铃薯的地上生物量、水分利用效率及大中薯率,
是黄土高原半干旱区一项有效的节水增产措施。 |

The field experiment of water harvesting modes wa
s conducted in Loess Plateau by planting potato with five treatments: (1) contou
r ridging; (2) contour ridging + film mulching on ridge; (3) contour ridging + g
eosynclinal in furrow; (4) contour ridging + film mulching on ridge + geosynclin
al 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 b
ulk density, and increase remarkably the aboveground biomass, water use efficien
cy and proportion of large and middle potatoes, therefore it was an effective wa
ter saving agricultural practice in the semi-arid area of Loess Plateau in Chin
