摘　　要：通过深翻整地、施用微生物改良剂、覆膜播种栽培等技术手段,致力于解决辽西半干旱区花生重茬栽培产量不高不稳问题。试验表明,倒茬、深翻可改善土体构造和土层结构,增加土壤孔隙度,降低土壤容重,使土壤固液气比例趋于协调,并可促进养分释放和减轻病虫害;增施有机肥可增加土壤有机质含量,提高地温和和蓄水能力;配施中微量元素有助于缓解花生重茬栽培养分偏耗。4种处理均有克服重茬种植障碍的效果,尤以深翻25~30 cm+有机肥+中微量元素综合效果为佳。The paper aims to solve the problem of low and unstable yield of peanut crop self-cultivation in the semi-arid area of western Liaoning province by means of deep plowing,application of microbial modifier,film coating seeding and cultivation.The results showed that stubble and deep turning could improve the soil structure and soil layer structure,increase soil porosity,reduce soil bulk density,harmonize the proportion of soil solid liquid gas,and promote the release of nutrients and reduce pests and diseases;The application of organic fertilizer can increase soil organic matter content,soil temperature and water storage capacity;The combined application of microelement can alleviate the excess nutrient consumption in peanut crop production.All the four treatments have the effect of overcoming the obstacle of continuous cropping,especially the combined effect of 25~30 cm+organic fertilizer+microelement is the best.
