摘要
豚草具有很强的生态适应性,其种子萌发受温度的制约明显,豚草从侵入某一地区到进入稳定阶段以前,其群聚度往往与侵入时间的长短呈正相关,当外界阻力达到或接近足够阻止豚草种群在该地区的继续扩展时,此种群就进入了稳定阶段。建议采取综合防除措施。
A preliminary study on ecological adaptability of Ambrosia artemisiifolia L. was held The germination of the seeds is closely related to temperature. The correlation between the population density and time of dispersal is positive in invision of Ambrosia artemisiifotia L.. If there is a balance between environmental resistance and contagious dispersion of the plant the population will reach a stable stage.
