The invention discloses an application and a method for knocking out a poplar LUX1 gene in delaying growth stop or dormancy time under short day, and the poplar LUX1 gene is identified and obtained through amino acid sequence comparison with arabidopsis thaliana LUX. The poplar LUX1 gene is a protein for coding an amino acid sequence as shown in SEQ ID No.1. The LUX1 gene is knocked out through a CRISPR / Cas9 editing system, and the time that the poplar enters the dormancy period due to short sunlight in autumn is delayed, so that the poplar germplasm with long growth period and high biomass is obtained. After the LUX1 gene is knocked out, terminal bud growth stop and stem cambium activity reduction in the seasonal growth process of the poplar can be delayed, so that wood development is promoted. Deferring of the dormancy time under the autumn short-day condition has a great application prospect for prolonging the growth period of the trees so as to improve photosynthetic carbon sequestration and biomass accumulation.
