施肥对毛竹林产量影响的Meta分析
Meta-analysis of the effect of fertilization on the yield of Phyllostachys edulis forest
摘要
Abstract
[Objective]The fertilization regime and its composition are crucial in determining the yield of Phyllostachys edulis(moso bamboo)forests.There is ongoing debate over the optimal fertilization strategy for these forests.This study aims to synthesize existing literature through a Meta-analysis to compare the impacts of total fertilization amounts and nutrient ratios on yield and its contributing factors,ultimately proposing a more universally applicable fertilization plan for moso bamboo forests.[Method]In this Meta-analysis,relevant data concerning moso bamboo,fertilizer application,and yield were collected and aggregated from various databases.The data underwent categorization and analysis to systematically explore the effects of total fertilization,and the proportions of nitrogen,phosphorus,and potassium fertilizers,on the yield of Moso bamboo forests and their contributing factors.[Result]Fertilization was found to significantly enhance various metrics:yield of new bamboo(YB)by 42.76%,shoot yield(YS),including both spring and winter shoot yields,by 57.01%,spring shoot yield(YSS)by 62.88%,winter shoot yield(YWS)by 67.78%,diameter of new bamboo(DB)by 7.22%,height of new bamboo(HB)by 8.17%,the number of mature bamboos(NB)by 35.84%,the number of shoots(NS)by 40.35%,the number of spring shoots(NSS)by 38.35%,and the number of retrogressed spring shoots(NRSS)by 33.38%.A positive correlation was observed between the proportion of phosphorus fertilizer and YB,but a negative correlation with YSS and YWS.In contrast,the proportion of potassium fertilizer showed a negative correlation with YB and a positive correlation with YSS and YWS.[Conclusion]For timber-producing bamboo forests,the recommended total fertilization amount should range from 228.7 to 337.5 kg/hm2,with nitrogen fertilizer comprising 50.9%-62.5%,phosphorus between 14.0%and 32.7%,and potassium lower than 16.4%.For shoot-producing forests,the total fertilization should not exceed 228.7 kg/hm2,with nitrogen proportions between 37.8%and 62.5%,phosphorus below 22.3%,and potassium above 24.9%.In dual-purpose forests,fertilization amounts should be maintained between 228.7 and 337.5 kg/hm2,with nitrogen at 50.9%-62.5%,phosphorus at 14.0%-22.3%,and potassium controlled between 16.4%and 24.9%.关键词
