Born by the roadside, born in the field.

In wild conditions, the crabgrass generally emerges in May-June, heads and blooms in July-September, and ripens in August-65438+1October. The growth period of artificial planting is about 150 days. The tillering ability of crabgrass is strong. A well-grown plant can produce 8- 18 stems and branches, and each stem and branch can reach as many as 32 skills. Therefore, in the case of grazing or mowing, its regenerative power is still quite strong. According to the data of Hunan Animal Husbandry and Veterinary Research Institute, it can be mowed 3-4 times during the growing period. When mowing, the stubble should be above 10 cm, too low will reduce its reproducibility. The crabgrass is a mesophyte widely distributed in the ecological amplitude. It can adapt to the climatic conditions from temperate to tropical. Like wet, good fertilizer, like light, the requirements for soil are not strict, and it can grow well in weak acid and alkali soil. Its species spread quickly, its reproduction is strong, its plants grow fast and its branches are many. Therefore, it is highly competitive and widely grows in various herb communities such as fields, roadsides, ditches, floodplains and hillsides.
