玉米套种绿肥模式对连作田土壤肥力及产量的影响

摘要

Through the research of interplanting corn and green manure mode,the results indicated that reasonable interplant would enhance the utilization rate maximally;plowing under green manure could improve soil structure.That was an effective way to achieve the efficient cultivation of high-yielding corn. By interplanting corn and vicia sativa with wide row spacing 90 cm ,narrow row spacing 40 cm,which could increase soil organic matter by 0.01%as well as corn production by 13.2%.%通过对连作玉米田套种绿肥模式的研究，结果表明：合理的套种能最大限度地提高土地利用率，绿肥翻压后能改善土壤结构，提高土壤肥力，是实现玉米高产高效栽培的有效途径。玉米套种箭舌豌豆宽行距90 cm、窄行距40 cm能使土壤有机质含量提高0.01%，玉米增产13.2%。
