摘　　要：阜新地区具有生产优质高产玉米的先天气候优势,但农业生产长期处于极其脆弱和不稳定的状态,如何蓄水保水、提高春季土壤墒情、保障出苗率则成为决定玉米产量的重要因素。通过试验对秸秆覆盖技术和中耕深松技术进行分析,结果表明,适合阜新地区的秸秆覆盖量是400kg/667m^(2),中耕深度25cm,中耕周期1a,这样产量增加明显。Fuxin area has the inherent climate advantage of producing high-quality and high-yield corn,but the agricultural production is in an extremely fragile and unstable state for a long time.How to store water and preserve water,improve the soil moisture in spring and guarantee the seedling emergence rate become important factors to determine the corn yield.The straw mulching technology and intertillage subsoiling technologyare analyzed through experiments,there sults show that the straw mulchinga mount suitablefor Fuxinareais 400kg/667 m^(2),the intertillage depth is 25 cm,and the intertillage cycle is 1 a,so the yield increases obviously.
