A preliminary report on the population quantity of goosegrassin corn-rice rotation field |
| |
| Abstract: | In this paper, a 2-year experiment was conducted to investigate the growth of goosegrass in the corn-rice rotation field in southern hunan. By using the inverted "W" nine-point sampling method, the quantitative dynamic indexes such as density, plant height, coverage, fresh weight and so on were determined, and the changes of the population quantity of goosegrass were monitored, so as to explore the scientific rules and lay a theoretical foundation for the rational selection of crop planting methods and the biological control and elimination of weeds in farmland. |
