Rice cultivation in our province to seedling-based approach. Seedling damage is generally the main barnyard grass, cattle wool grass, some seedling field eye food, Jing Triangular also more serious. Barnyardgrass gradually germinated in the whole field, with three rows of seedling and seedling seedling standing flat and three-leaf stage drainage dew (sun) seedling more concentrated after the three batches, so it is irregular, as long as more than a month; cattle wool grass, Ocimum vegetables, Jing Triangular weeds in the seedlings 4 to 5 leaf stage damage. Artificial weeding large, difficult to divider. In recent years, trials and promotion of weeding ether and propanil to seedling chemical weeding, although it can play a role, but also save
