摘　　要：１９９６～１９９８年不同带距对旱地麦玉薯三熟产量效应联合分析表明，４米是旱三熟高产稳产的种植带距，与１．６７米比较，夏玉米区小麦增产３．６％，玉米减产 ４． ４％，甘薯增产 ３８． ３％，间作大麦增 ３４． ５％，周年粮食增长 ４． ３％；春玉米区小麦减产４．０％，玉米增产５．９％，甘薯增产１７．５％，秋季增种黄豆增产２３．１％，周年粮食增长 ７． ３％。建立了带距与各作物产量的回归方程。In 1996 to 1998, the yield effect of wheat/maize/sweet potato three harvest of a year in different strip width in dry land was analyzed .The results showed 4 meters were the planting strip width of high and stable yield in three harvest of a year in the dry land compared to 1 .67 meters. In summer maize plot, wheat yield was increased 3.6%, maize yield was decreased 4.4%, and sweet potato, barley and annual crop yield were increased 38.3%, 34 .5% and 4. 3%, respectively. In spring maize plot, the yields of maize, sweet potato, soybean and annual crop were increased 5. 9 %, 17. 5 %, 23. 1 % and 7. 3 %, respectively. The regression equation between strip width and crop yield was conducted.
