土壤微生物膜固沙对沙生植物幼苗光合和荧光特性的影响
Effects of soil microbial films sand fixation on photosynthesis and fluorescence characteristics of psammophyte seedlings
为揭示土壤微生物膜固沙技术对沙生植物幼苗光合和荧光特性的影响,以沙冬青(Ammopiptanthus mongolicus)和沙打旺(Astragalus laxmannii)幼苗为研究对象,设置不同菌剂施用方式(喷施、混施)和施用量(0、1、3、5、7 和 10 g·kg-1)开展盆栽试验,比较分析土壤微生物膜形成后植物气体交换和叶绿素荧光特征。研究结果表明:(1)当菌剂施用量大于 1 g·kg-1 时,固结层硬度和厚度显著高于对照组(P<…查看全部>>
In order to reveal the effects of soil microbial film sand fixation on photosynthetic and fluorescence characteristics of psammophyte seedlings,Ammopiptanthus mongolicus and Astragalus laxmannii seedlings were selected.Pot experiment with different application methods(spray,mix)and application amount(0,1,3,5,7 and 10 g kg-1).The characteristics of plant gas exchange and chlorophyll fluorescence after soil microbial biofilm formation were analyzed.The results…查看全部>>
