不同杂草管理方式对山地胶园土壤环境和胶乳鲜重的影响
Effects of different weed management methods on soil environment and fresh latex weight in a mountainous rubber plantation
摘要
Abstract
This study aims to investigate the effects of different weed management methods on the soil environment and latex wet weight in a mountainous rubber plantation.The weeds in the plantation of the rubber tree clone'Yunyan 77-4'were managed with five methods:chemical weeding(CW),manual weeding(MW),green manure cover and incorporation(GC),weed trench incorporation(WT),and conventional management(CK).A long-term field monitoring was conducted from 2014 to 2023 and yielded the following results.Different treatments exerted significant influences on soil bacterial community structure and some parameters of physicochemical properties.The number of unique OTUs and diversity indices of soil bacteria were the highest in the WT treatment and also exhibited higher diversity indices,while the MW treatment showed lower values in both unique OTU number and diversity index of soil bacteria.The structure of the soil bacterial community was similar between the two soil layers(0-20 cm and 20-40 cm)across all treatments.Chloroflexi,Actinobacteriota,Proteobacteria,Acidobacteriota,and Firmicutes represented the dominant phyla.Regarding soil physicochemical properties,the WT treatment significantly increased the soil organic matter(OM)content,pH value,exchangeable calcium(ExCa)and exchangeable magnesium(ExMg)contents.The GC treatment was effective in elevating available phosphorus(AP)and available potassium(AK)contents and improving soil structure.In contrast,the MW treatment resulted in decreases in soil OM,total nitrogen(TN),and hydrolysable nitrogen(HyN).The data of annual latex wet weight showed that the average annual latex wet weight of the WT and GC treatments in 2022、2023 was higher than that of the CK and MW treatments.Redundancy analysis identified soil pH,OM,total phosphorus(TP)content were the most critical factors affecting latex wet weight,contributing 58.6%,47.4%,47.4%to the variation.In conclusion,the WT and GC treatments exert positive effects on improving the soil environment and increasing the latex wet weight of rubber trees.关键词
