摘要
竹纤维菌肥是一种集保水、生根、增肥功能于一体的竹材料为主的微生物肥料。为探究竹纤维菌肥对风沙土土壤水分入渗和蒸发的影响,本研究设置4种浓度(0.10%、0.20%、0.50%、1.00%)的竹纤维菌肥以及不混施竹纤维菌肥作为对照组(CK),开展室内土柱模拟及蒸发试验。结果表明:(1)湿润锋运移距离和累积入渗量随着竹纤维菌肥浓度的增加呈减小趋势,在相同时间下,各个试验处理组较对照组均有明显抑制效果。(2)随着竹纤维菌肥浓度的增加,各处理组的土壤平均含水率相较于对照组分别增加了0.12%、0.46%、2.86%和3.41%,且随着土层深度的增加,土壤含水率呈减小趋势。(3)通过比较Rose模型和Black模型模拟结果,发现Rose模型拟合效果最佳。此研究为干旱和半干旱地区风沙土壤的土壤水分管理提供了科学依据。
Bamboo microbial fortilizer is multifunctional microbial material with water retention,root promotion,and fertility enhancement.In order to explore the effect of bamboo microbial fortilizer on the characteristics of soil water infiltration and evaporation in wind-sand soil,this study conduced soil column simulation and evaporation experiment by four different concentrations of bamboo microbial fortilizer(0.10%,0.20%,0.50%and 1.00%)and control(CK)with non-mixed microbial fortilizer.The results showed that:(1)The wetting front migration distance and cumulative infiltration decreased with the increase of bamboo microbial fortilizer concentration.At the same time intervals,all treatments had significantly inhibitory effects compared with CK.(2)With the increase of bamboo microbial fortilizer concentration,the average soil moisture content of each treatment group increased by 0.12%,0.46%,2.86%and 3.41%,respectively,compared with CK.Beside,with the increase of soil depth,the soil moisture content showed a decreasing trend.(3)By comparing the simulation performance of Rose model and Black model,the Rose model fitted better.This study provides a reference for soil moisture management of aeolian sandy soil in arid and semi-arid areas.
