Abstract

Soil moisture is a key parameter of soil monitoring for observation of vegetation growth, predicting crop production, and improving water resource management. In this study, the objective is to compare the evolution of soil moisture in different mulches to determine the best mulch and its characteristics of infiltration in the soil. The experiment was conducted during the summer season in July-September 2022 on four different mulches (wood chips, sawdust, straw, mixture), and control at the experimental plot of Blida. The results showed that silt is the main matrix of the soil. The analysis of infiltration data identified modified Kostiakov as the best model of the study site, whose period of plant growth represents the phase during which we have a better infiltration under the mixture. The application of the mulch changes the moisture mainly at 15 cm and the conductivity at 10 cm. In addition, the mixture is the best mulch to conserve moisture in the soil while reducing the frequency of irrigation. The correlation between soil moisture and conductivity was overall very good. This was due to the effect of mulch, soil texture, plant root development, and capillary rise.

地膜对番茄作物土壤湿度和水分渗透的影响

土壤水分是土壤监测的一个关键参数，用于观察植被生长、预测作物产量和改善水资源管理。本研究的目的是比较不同地膜中土壤水分的变化情况，以确定最佳地膜及其在土壤中的渗透特性。实验于 2022 年 7 月至 9 月的夏季进行，在布利达的实验地块使用了四种不同的地膜（木屑、锯末、秸秆、混合物）和对照。结果表明，淤泥是土壤的主要基质。对渗透数据的分析表明，改良的科斯蒂亚科夫模型是研究地点的最佳模型，其植物生长期代表了在混合物下我们有更好渗透的阶段。覆土主要改变了 15 厘米处的湿度和 10 厘米处的传导性。此外，该混合物是保持土壤水分的最佳覆盖物，同时减少了灌溉次数。土壤水分和导电率之间的相关性总体上非常好。这是由于地膜、土壤质地、植物根系发育和毛细管上升的影响。
