| 摘 要： | 为了研究不同耕作方式对土壤理化性状和玉米产量及经济效益的影响，通过传统翻耕、浅旋根茬还田常规播种和机械灭茬免耕播种3种耕作方式对玉米田土壤水分、土壤速效养分、玉米产量性状及产量和经济效益影响的比较，明确了不同耕作措施对玉米田土壤理化性状和玉米产量的影响。结果表明：机械灭茬免耕播种和浅旋根茬还田常规播种的出苗率、不同土层含水量、玉米产量性状、单位产量及总收益均高于传统翻耕，且浅旋根茬还田常规播种和机械灭茬免耕播种的出苗率比传统翻耕高3.3%和7.8%，不同层次土壤含水量、土壤养分的大小顺序均为机械灭茬免耕播种＞浅旋根茬还田常规播种＞传统翻耕，机械灭茬免耕播种和浅旋根茬还田常规播种处理的玉米产量比分别高9.01%和3.23%，纯收入比CK增加4305元/hm2和1965元/hm2，即分别比CK高出36.98%和17.65%。说明机械灭茬免耕播种措施最好，而浅旋根茬还田常规播种耕作方法又优于传统翻耕。

| Abstract: | In order to study the effects of different tillage methods on soil of physicochemical properties and maize yield and economic benefit, the paper made the comparison of different factors among three tillage methods including conventional tillage, conventional sowing with shallow rotary tillage and stubble remaining in field and no-tillage with mechanical stubble breaking. The results showed that, the emergence rate, soil water content of different soil layers, maize yield traits, maize yield, total income and pure income of conventional sowing with shallow rotary tillage and stubble remaining in field and no-tillage with mechanical stubble breaking were all higher than the conventional tillage, the emergence rate of conventional sowing with shallow rotary tillage and stubble remaining in field and no-tillage with mechanical stubble were 3.3% and 7.8% higher than that of the conventional tillage, the soil water content of different soil layers and soil available nutrient content showed no-tillage with mechanical stubble breaking > conventional sowing with shallow rotary tillage and stubble remaining in field > conventional tillage. The maize yield of no-tillage with mechanical stubble breaking and conventional sowing with shallow rotary tillage and stubble remaining in field were 9.01% and 3.23% higher than that of conventional tillage, the pure income increased by 4305 yuan/hm2 and 1965 yuan/hm2, and higher than 36.98% and 17.65% than that of the conventional tillage. This indicated that no-tillage with mechanical stubble breaking was the best tillage methods, and conventional sowing with shallow rotary tillage and stubble remaining in field was better than the conventional tillage. |
