- Abstract:
- In order to clarify the allelopathy effect of root diffusate of different crops on soybean seeds,the effect of root diffusates of crop in different rotation systems on germination and sprout growth of soybean seed were tested by the filter paper method.The germination rate of soybean seed was 63.3% in the root diffusates of soybean planted in soybean continuous cropping for 12 years(S…SS)，which indicated germination percentage of soybean seed inhibited by the soybean root diffusates of continuous cropping system in comparison with Corn-Soybean-Corn(CSC)rotation system with 96.7% germination.Germination rate and germinability of soybean seed were almost the lowest in the root diffusate of sugarbeet in comparison with other crops planted in Wheat-Soybean-Wheat(WSW)，Soybean-Wheat-Corn(SWC)and CSC rotation systems，and the root diffusates of sugarbeet planted in all the rotation systems were not beneficial to growth of soybean sprouts.Germination and sprout growth of soybean seed were increased by the root diffusates of flax planted in all the rotation systems.The effect of corn root diffusate on soybean seed germination wasn’t significant in five rotation systems except WSW.The root diffusates of wheat planted in CSC，SWS and Nudation benefited germination and sprout growth of soybean seed.The effect of the root diffusates of same crop planted in different rotation systems or different crops planted in the same rotation system on germination and sprout growth of soybean seed was markedly different.
