Abstract:

The experiment collected 0~40 cm soil with Chlorinuron-ethylon residue from soybean field to do the pot trial.The seedling rate，plant height，root length and weight of beet(Beta vulgaris)at seedling period were measured to study the spatial distribution of Chlorinuron-ethylon herbicide and its effect on other crops in soybean field.Results showed that the Chlorinuron-ethylon was mainly distributed in 0~20 cm soil，and the residual amount decreased with soil depth.The 0~20 cm soil showed significant phytotoxicity to beet，especially in 0~10 cm，the beet all died in four leaves period.Beet growth was significantly inhibited by 10~20 cm soil treatment，with plant height reduced 37%，fresh weight decreased 31.7%.Beet growth was not affected by under 20 cm soil，which indicated that the residual amount of Chlorinuron-ethylon had no significant effect on next seasonal crop.Results reveal the distribution of chlorinuron-ethylon residue in different soil depths and its effect on beet growth in seedling period，which will provide references to reduce residual phytotoxicity of herbicide.
