In order to optimize the technology of increasing yield by soaking cassava cutting(SCC)in the solution of Chlorocholine Chloride(CC),the effects of the SCC for 6 h and 12 h by different concentrations of CC on the cassava agronomic traits,yield and quality of storage root(SR)were investigated.The results showed that,in comparison with non-soaking,200.00 mg/L,300.00 mg/L SCC for 6 h and 100.00 mg/L SCC for 12 h significantly dwarfed the plant height,0.00～100.00 mg/L SCC for 6 h significantly increased the length of SR,and 300.00 mg/L SCC for 6 h and 200.00 mg/L SCC for 12 h significantly increased the diameter of SR,200.00 mg/L SCC for 6 h significantly increased the soluble sugar content of dried SR,and 200.00 mg/L and 300.00 mg/L SCC for 6 h significantly increased the starch content of dried SR.The best treatment was 300.00 mg/L SCC for 6 h,and it significantly increased the fresh yield of SR by 41.7％,the starch yield by 64.6％and harvest index by 10.5％.The sub-optimum treatments were 100.00～200.00 mg/L SCC for 6 h and 12 h,which significantly increased the fresh yield of SR and starch yield,and also increased the harvest index.Based on comprehensive analysis,the technology of 100.00～300.00 mg/L SCC for 6 h was recommended to increase the fresh yield of SR and starch yield.
