摘　　要：本文选取稀释不同倍数的木醋液以滴灌的方式施加至种植甘草、紫穗槐、梭梭三种植株的盐碱土壤,研究棉秆木醋液对盐碱土壤的作用影响。试验结果表明:添加木醋液对种植甘草的盐碱土壤容重作用效果最显著,且施加800倍木醋稀释液时,土壤容重下降最高,达到13.75%;随着试验周期的延长,施加木醋液对三种植物土壤有机质均有明显的增加。甘草在0~20 cm和20~40 cm土层最优处理组均为1 000倍稀释液;紫穗槐在0~20 cm和20~40 cm土层最优处理组分别为1 400倍稀释液和1 000倍稀释液;梭梭在0~20 cm和20~40 cm土层最优处理组均为1 000倍稀释液;低浓度的木醋液的施加短期内会使甘草、紫穗槐土壤全盐含量上升,但随试验周期增长逐渐下降至初始值以下。梭梭的作用效果相反,随试验周期增长呈现先降低后升高的趋势。为木醋液作为土壤改良剂的施加含量、最佳作用时间和适用植株起到了筛选的作用。In this paper,the effect of cotton stalk wood vinegar on saline-alkali soil was studied by applying drip irrigation to saline-alkali soil of three plants of Licorice,Amorpha and Haloxylon. The results showed that adding wood vinegar had the most obvious effect on the density of saline-alkali soil,and the soil bulk weight decreased to 13. 75% by applying 800 times of wood vinegar dilution; With the extension of test period,the application of wood vinegar to the soil organic matter of three kinds of plants increased obviously. The optimal treatment group for 0 - 20 cm and 20 - 40 cm soil layers were 1 000 times thinner,and the optimal treatment group of Amorpha in 0 - 20 cm and 20 - 40 cm were 1 400 times thinner and 1 000 times thinner respectively,and the optimal treatment group of Haloxylon in 0 - 20 cm and 20 - 40 cm were 1 000 times thinner; The application of low concentration of wood vinegar will increase the total salt content of the Licorice and Amorpha in a short term,but decrease with the test cycle gradually below the initial value. The effect of Haloxylon was the opposite,and then the increase was decreased with the increase of test cycle. The effect of wood vinegar on the applied content,the best time of action and the suitable plant was screened.
