Intercropping efficiency of Pteris vittata with two legume plants: Impacts of soil arsenic concentrations

Hyperaccumulator Solanum nigrum L. Intercropping Reduced Rice Cadmium Uptake under a High-Bed and Low-Ditch Planting System

“…A significant decrease in rice Cd uptake was also observed in flood cultivation mode, which might be due to the significant amount of Cd that can be accumulated in water. This study supports previous studies suggesting that the intercropping system decreases plant HM uptake [1,5,11]. In addition, it is important to mention that less Cd was accumulated in rice grown under the high-bed and low-ditch cultivation mode [28].…”

“…Phytoremediation is considered one of the most advantageous remediation techniques due to its cost-effectiveness, suitability for large-scale application, ecological benefits, and environmental friendliness [10]. Distinctive plant species known as accumulators and hyperaccumulators have the ability to absorb and accumulate high levels of HMs in their tissues without being negatively affected [11,12]. These plants have shown promising results in removing HMs such as Cd, Zn, and Pb from contaminated soil [12].…”

Hyperaccumulators’ Diversity Enhances Cd-Contaminated Soil Restoration and Reduces Rice Cd Uptake under an Intercropping System

“…Intercropping between hyperaccumulator plants and low-accumulated crop varieties can stabilize and reduce crop HM uptake while increasing the restoration efficiency of the contaminated soil. ,, Intercropping between hyperaccumulator plants and ordinary crops has been used to improve the biomass of hyperaccumulator plants and their HM absorption without compromising the growth and yield of the intercropped crop. ,, However, the impacts of hyperaccumulator identity and diversity under a rice/hyperaccumulator plant intercropping system on Cd concentration in soil and rice uptake still need further investigations.…”

“…Intercropping is a cultivation method that increases farmland productivity. − For instance, studies have shown that intercropping between legumes and cereals can significantly increase the plant’s leaf area index and the total amount of dry matter accumulation per unit area of each crop. , In addition, it has been demonstrated that intercropping between cotton and peanuts improves economic benefits . Moreover, intercropping simultaneously enhances plant biomass and disease and insect resistance .…”
