Effect of Different Water and Fertilizer Treatments on the Cold Resistance of Wudu Zanthoxylum bungeanum
To explore the effects of different water and fertilizer management on cold resistance evalua-tion of Zanthoxylum bungeanum Maxim.A pot experiment with four factors and a four-level orthog-onal design,Set the soil moisture 25%,45%,65%,and 85%field water capacity FWC,Set the fer-tilization level nitrogen(N 0,90,180,and 360 kg/hm2),phosphorous(including P2O5 0,50,100,and 200 kg/hm2),and potassium(K2O 0,90,180,and 360 kg/hm2).Systematically observed the changes in cold resistance indicators of Zanthoxylum bungeanum Maxim wuduseedings under different water and fertilizer combinations,A subordinate function was applied to comprehensively evaluate the impact of different water and fertilizer on the cold resistance of seedlings.The results showed that H11(N180P100K180+65%FWC)treatment caused the optimal comprehensive cold resistance value of Zanthoxylum bungeanum Maxim wudu seedings and the fertilization treatment is significantly higher than the non fertilization treatment.The results suggested that appropriate soil moisture and N,P,and K fertilizer application are important for enhancing Zanthoxylum bungeanum Maxim wudu seed-ings cold resistance comprehensive value.
