不同管理措施对花椒幼苗的影响

Effects of Different Management Measures on Prickly Ash Seedlings

为了分析不同管理措施对花椒幼苗的影响。在云南省昆明市选择某花椒试验基地,依据不同管理措施设置四个处理,Z1(自然生长,不进行人工抚育处理)、Z2(整地+栽植管理)、Z3(整地+栽植管理+施肥)、Z4(整地+栽植管理+施肥+病虫害防治),分析不同处理后花椒幼苗生长情况及对花椒生理特性的影响。结果得知不同措施进行花椒管理,花椒幼苗生长存在差异(P<0.05),Z1和Z2的地径无明显差异,Z2和Z3的苗高无明显差异(P>0.05),Z4的地径和苗高指标优于其他处理,地径和苗高是Z1处理的1.86倍和1.41倍;Z4处理的叶干重、茎干重、根干重、生物量均高于其他处理(P<0.05),整体排序是Z4>Z3>Z2>Z1;Z4处理超氧化物歧化酶指标、过氧化物酶指标、过氧化氢酶指标和多酚氧化酶高于其他处理。因此证明不同管理措施对花椒幼苗影响不同,整地+栽植管理+施肥+病虫害防治的综合管理措施,可促进花椒幼苗生长,改善花椒生理特性,从而实现花椒栽培高产的目标。

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 artificial 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 Sichuan pepper management resulted in differences in the growth of Sichuan pepper seedlings(P<0.05).There was no significant difference 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 treatments(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 measures have different effects on Sichuan pepper seedlings.The comprehensive management measures of soil preparation,planting management,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.
