玉米根系为须根系,株高,叶大而且长,为需肥(尤其氮肥)、需水较多的 C_4植物。而大豆的根系为直根系,株矮,叶小而圆,能与根瘤菌共生而进行生物固氮作用,是需磷、钾肥较多的 C_3植物,二者间作,可有效地改善田间气候、土壤环境,增长效果明显。但在玉米主产区,以产玉米为主,传统的2:2、2:3间作方式,造成玉米、大豆产量过于平均,总产
The root systems of maize are fibrous roots, plant height, large and long leaves, which are C_4 plants that need fertilizer (especially nitrogenous fertilizer) and need more water. Soybean root system is straight root system, plant short, small and round leaves, can symbiosis with rhizobia for biological nitrogen fixation, phosphorus and potassium fertilizer is more C_3 plants, between the two can effectively improve the field climate, soil Environment, the growth effect is obvious. However, in the main producing areas of corn, the main production of corn, the traditional 2: 2, 2: 3 intercropping methods, resulting in corn, soybean production is too average, total output
