A plastic pot open-air trial was conducted with the (seashore paspalum) using different rates of biochar or compost addition to sandy loam soil and two water treatments (60% and 20% of the water-holding capacity of the control) during three seasons (winter, spring, and summer). Paspalum growth, physiological characteristics, and physicochemical properties of soil were investigated. The effect of biochar on soil properties was assessed using factor analysis of mixed data (FAMD). Additionally, multiple factorial designs (MFA) were used to examine the impact of three biochars on physiological functions. Peanut hull biochar application increased soil fertility and chlorophyll concentration of paspalum leaves significantly compared to the other biochars. Physiological characteristics were significantly improved with peanut hull biochar under summer compared to winter and spring due to the accumulation of nutrients in the soil by the decomposition of biochar. The application rate of the three biochars reduced the water requirements of paspalum. The best result was obtained by incorporating 6% peanut hull biochar into the soil, which resulted in better soil quality and healthy grass in dryland conditions while using 47.5% less water. These findings can be suitable for golf managers and can serve as a solution for dry zones.
进行了一项塑料盆露天试验，使用海滨雀稗，在砂壤土中添加不同比例的生物炭或堆肥，并设置两种水分处理（分别为对照持水量的60%和20%），试验持续三个季节（冬季、春季和夏季）。研究了海滨雀稗的生长、生理特性以及土壤的理化性质。使用混合数据因子分析（FAMD）评估生物炭对土壤性质的影响。此外，采用多因素设计（MFA）研究三种生物炭对生理功能的影响。与其他生物炭相比，施用花生壳生物炭显著提高了土壤肥力和海滨雀稗叶片的叶绿素浓度。由于夏季生物炭分解使土壤中养分积累，与冬季和春季相比，夏季施用花生壳生物炭时生理特性得到显著改善。三种生物炭的施用量降低了海滨雀稗的需水量。在土壤中掺入6%的花生壳生物炭效果最佳，在旱地条件下可改善土壤质量并使草生长健康，同时用水量减少47.5%。这些研究结果适用于高尔夫球场管理者，可为干旱地区提供解决方案。
