大豆高产必须具有发达健壮的根系。这不仅能增强吸收作用,还能强化根瘤固氮作用,提高光合效率。然而当前生产上大豆根系远非发达健壮,尤其在多年重迎茬情况下,根部病虫害相当严重,已成为大豆增产的重要限制因素。因而大力开发壮根栽培技术乃是提高大豆产量,推进大豆生产发展的 High yield soybean must have a robust root system. This not only enhances the absorption but also strengthens the nodule nitrogen fixation and enhances photosynthetic efficiency. However, the current production of soybean roots is far from developed and robust, especially in many years of heavy stubble, the root causes of pests and diseases is very serious, soybean production has become an important limiting factor. Therefore, vigorously develop strong root cultivation techniques but to improve soybean production, promote the development of soybean production
