Abstract:
To understand the physiological bases of soybean yield with film mulching between rows，the soil microorganism regions and soil fertility of soybean root system with film mulching between rows for Heinong 40 were researched compared with the control.Results suggested that the amount of three major soil microorganism didn’t change under film mulching between rows，with bacteria the most，fungi the least.Film mulching between rows increased the total numbers of microorganism and the increments of bacteria，actinomyces and fungi appeared fastigium at R1，R2 and R1.The fastigium of total numbers appeared at V2.Film mulching increased the content of biology carbon of soil microorganism regions.Film mulching also increased the contents of N，P and K which can be used by roots compared with the control at different soybean growth stage.Thus，we considered that the increasing contents of the numbers of soil microorganism and biology carbon are one of the physiological bases of soybean high-yielding with film mulching between rows，which can advance the transformation of soil nutrient，improve the growth of soybean，increase the using efficiency of the light energy of soybean population and enhance the final yield.
