The invention provides a 
lagerstroemia indica 
seedling cold storage and high temperature season planting method. The method comprises the steps of conducting cuttage breeding production on 
lagerstroemia indica seedlings in the 
lagerstroemia indica 
seedling growth period; digging out the 
lagerstroemia indica seedlings and binding the 
lagerstroemia indica seedlings according to bundles in the 
lagerstroemia indica seedling dormant period; after the lagerstroemia indica seedlings are subjected to sterilization, preservation, 
water retention and 
simulation temporary planting, covering the lagerstroemia indica seedlings with 
plastic film and then putting the lagerstroemia indica seedlings in 
cold storage. By means of the lagerstroemia indica seedling 
cold storage and high temperature season planting method, by conducting cuttage breeding production on the lagerstroemia indica seedlings in the growth period, covering the lagerstroemia indica seedlings with the 
plastic film and putting the lagerstroemia indica seedlings in cold storage after conducting the sterilization, the preservation, the 
water retention and 
simulation temporary planting on the lagerstroemia indica seedlings in the dormant period, the lagerstroemia indica seedlings can be transplanted in the high temperature season, soil ball 
transplanting is not needed, the 
transplanting survival rate is increased, the 
transplanting cost is lowered, cross-region 
pollution of diseases and insects can be prevented, 
soil resources are protected, so that when lagerstroemia indica is transplanted, requirements on time, climate andtransportation conditions are flexible, and the transplanting cost is saved.
