摘　　要：东北风沙半干旱区花生连作障碍问题十分突出,缓解花生连作障碍对该区域的花生生产具有重要意义。研究不同茬口对花生栽培的影响,结果表明:不同茬口对花生生长发育、产量、产量性状以及土壤酶活性影响显著。轮作换茬种植方式是缓解东北风沙半干旱区花生连作障碍的有效途径。Peanut continuous cropping obstacle is very serious in the northeast sandstorm semi-arid region. Alleviating this obstacle is of vital significance to the peanut production in the region. The effect of different crop stubble on the peanut cultivation was studied. The results showed that the effect of different crop stubble on the growth, yield, yield traits in peanut and soil enzyme activity is significant. Rotation of crops planting mode is the effective way to relieve peanut continuous cropping obstacles in the northeast sandstorm semi-arid region.
