Abstract: The biology characteristics and harmfulness of Kummerowia striata were investigated. The highest plant height was (10.76±0.73) cm, the lowest (4.15±0.55) cm, and the average (6.46±2.58) cm. The longest main stem length was (22.33±3.31) cm, the shortest (9.02±0.74) cm and the average (12.07±4.61) cm. The maximum winding number was 61±18.16, the least 14±4.16 and the average 27±15.44. The longest branch length was (7.34±1.26) cm, the shortest (4.31±0.77) cm and the average (5.29±1.25) cm. The maximum number of seeds was 334±138.06, the least 51±24.24, and the average 120±97.83. The maximum root distribution area was (1 587.79±979.15) cm2, the minimum (101.65±32.67) cm2, and the average (352.68±595.96) cm2. The longest root branch was (6.78±2.08) cm, the shortest (3.35±0.90) cm and the average (4.28±1.38) cm. The most root branches were 15±6.96, the least 7±0.58 and the average 10±3.24. The maximum plant coverage was (23.89±11.09)%, the minimum (2.44±0.96)% and the average (6.71±7.86)%. The maximum planting density was 6±2.49, the minimum 4±1.00, and the average 5±1.58. A few associated plants of K. striata with low density and coverage also occurred.
