Effects of Different Management Measures on Prickly Ash Seedlings
To analyze the effects of different management measures on Sichuan pepper seedlings.Select a Sichuan pepper experimental base in Kunming,Yunnan Province,and set up four treatments based on different management measures:Z1(natural growth,no arti-ficial nurturing treatment),Z2(land preparation+planting management),Z3(land preparation+planting management+fertilization),and Z4(land preparation+planting management+fertilization+pest control).Analyze the growth of Sichuan pepper seedlings and their impact on the physiological characteristics of Sichuan pepper after different treatments.The results showed that different measures of Si-chuan pepper management resulted in differences in the growth of Sichuan pepper seedlings(P<0.05).There was no significant differ-ence in the diameter of Z1 and Z2,and there was no significant difference in the height of Z2 and Z3 seedlings(P>0.05).Z4 had better diameter and height indicators than other treatments,with a diameter and height 1.86 and 1.41 times higher than those of Z1 treatment;The leaf dry weight,stem dry weight,root dry weight,and biomass of Z4 treatment were higher than those of other treat-ments(P<0.05),and the overall ranking was Z4>Z3>Z2>Z1;The indicators of superoxide dismutase,peroxidase,catalase,and polyphenol oxidase in Z4 treatment were higher than those in other treatments.Therefore,it is proven that different management meas-ures have different effects on Sichuan pepper seedlings.The comprehensive management measures of soil preparation,planting manage-ment,fertilization,and pest control can promote the growth of Sichuan pepper seedlings,improve their physiological characteristics,and achieve the goal of high yield in Sichuan pepper cultivation.
