Abstract Enrichment of soils with organic amendments could increase the content of available nutrients, improve soil chemical characteristics and increase plant growth. In the current pots experiment, the influences of biochar (BC), humic acid (HA), and compost (CO) on barely growth were investigated under saline conditions. Barely plants grown on a clay loam soil and irrigated with saline water concentration of (EC = 13.8 dS m−1) were amended with BC, HA and CO at a rate of 1 or 3% of soil weight. The results showed that BC, HA and CO treatments had significant effects on the soil salinity, pH, organic matter (SOM), and plant nutrients. The results showed that the high rate application of BC, HA and CO increased the SOM by 14, 75 and 58% respectively, above the control. Consequently, the total chlorophyll as affected by the treatments can be arranged in descending order: BC3 > CO1 > CO3 > HA3 > HA1 > BC1 > C. The high rates of BC, HA and CO increased the dry biomass by 28.0, 21.6 and 39.7% respectively, above the control %, respectively, above the control. The investigated organic amendments increased the nutrients availability and uptake and enhanced the synthesis of chlorophyll in the plant tissues and this may be the reason of increasing the ability of barley to tolerate salinity.

一些有机改良剂对盐渍条件下大麦植株的影响

摘要 用有机改良剂富集土壤可以增加有效养分的含量，改善土壤化学特性，促进植物生长。在目前的盆栽实验中，研究了生物炭 (BC)、腐植酸 (HA) 和堆肥 (CO) 在盐水条件下对勉强生长的影响。几乎在粘壤土上生长并用盐水浓度（EC = 13.8 dS m-1）灌溉的植物用 BC、HA 和 CO 以土壤重量的 1% 或 3% 的比例进行修正。结果表明，BC、HA和CO处理对土壤盐分、pH值、有机质（SOM）和植物养分有显着影响。结果表明，BC、HA 和 CO 的高用量施用分别使 SOM 增加了 14%、75% 和 58%，高于对照。最后，受处理影响的总叶绿素可按降序排列：BC3 > CO1 > CO3 > HA3 > HA1 > BC1 > C。BC、HA和CO的高比例分别使干生物量增加了28.0%、21.6%和39.7% , 高于对照 %, 分别高于对照。所研究的有机添加物增加了植物组织中养分的可用性和吸收，并增强了叶绿素的合成，这可能是提高大麦耐盐能力的原因。
