摘　　要：大豆“三垄”技术具有显著的增产效应。对该技术中的垄作深松及分层施肥的增产效应进行的分析表明，“三垄”技术使土壤耕层加深、容重下降、大小孔隙比加大、土壤耕层的蓄水性能增强。在５、６月份，土壤耕层的增温效应显著；耕层土壤温度与产量均呈显著相关关系；田间持水量和土壤有效含水量均显著增加。促进了大豆根系的生长和碳氮的同化作用。１９８８～１９９０年３年平均增产２５．３３％。San-Lony'technique-a mechanized high yield comprehensive agrotechnique of upland -farming to soybean was created by Heilongjiang Aug.-lst Land Reclamation University.The first two key techniques of 'San-Long' which are ridge culture, deep tillage and layer fertilization are expounded only in this paper. The data in this paper indicated that the depth and water storage capacity of arable layer was increased with'San-Long' technique.'San-Long'technique increased the rate of capillary pore and non-capillary pore. Effect of temperature increase in arable layer in May and June reached significantly. And available soil moisture attained significant level. The correlativity of available soil moisture and soybean yield reached to 0.01 significant level by'San-Long'technique. The yield with'San-Long'and control of soybean got 2929.5kg/hm2 and 2337.5kg/hm2,separately, increased 25.3%.
