| Abstract: | The seeds of weedy rice with dark brown chaff mainly existed in the topsoil of rice field that is within the 0 -2 cm topsoil in Jiangdu, Jiangsu Province, which contained about 92.65% of the total weedy rice seeds with dark brown chaff. In the soil seed bank,the weedy rice seeds with dark brown chaff and with yellow chaff is in the ratio of 17.9 to 1.0 in the serious harmful plots, 1.58 to 1.0 in the medium harmful plot, and 0.17 to 1.0 in the minimum harmful plot. |
