针对三江平原地区低湿耕地湿、冷、硬、旱、板、瘦等限制大豆高产因素的特点,以“六五”试验的垄底深松、垄下分层深施肥、垄上双条精量点播为基础,采用工程、耕作与生物相结合的综合治理措施,建成一个低湿耕地大豆抗旱涝、高产稳产、抗病质佳、节能高效的生产规范化体系(模式)。通过加深耕层、改善土壤理化性质,扩大了土壤生态容量,有利于大豆和土壤微生物区系的生长发育。增产效果与经济效益显著。
According to the characteristics of low and wet cultivated land in wetland, cold, hard, dry, plate, thin and so on which restrict the high yield of soybean in Sanjiang Plain, On-demand basis, the use of engineering, farming and biological combination of integrated management measures to build a low-wetland soybean drought drought, high and stable yield, good disease resistance, energy efficient production standardization system (mode). By deepening the topsoil, improving soil physical and chemical properties, expanding the ecological capacity of soil, is conducive to soybean and soil microbial flora growth and development. Yield and economic benefits significantly.
