“…Aluminum species in the soil are determined by the pH [ 27 , 28 ]. The exchangeable aluminum concentrations that are toxic to plants were significantly negatively correlated with the pH in a wide variety of soils [ 25 , 29 ]. As the soil concentration of H + increased, and monomeric hydroxyl aluminum (such as Al(OH) 2+ and Al(OH) 2 + ) was gradually transformed into Al 3+ , and when the soil pH falls below 5.5, a large amount of soluble ionic aluminum will be released into soils.…”

The rampant bayberry decline disease has been regarded as related to soil with the long-term plantation bayberry. These parameters, hydrogen, aluminum, other alkali cations, and plant-related nutrients, were measured from the soil around diseased tree roots 10, 20, and 30 years old. The pH significantly declined in topsoil with increasing tree age and rose with increasing depth of the soil layer with an age of 10, 20, and 30 years. The concentration of exchangeable aluminum has risen significantly with the increase of the tree ages in the top soil layer and also in 0 to 40 cm soils layer with ten-year-old trees. In the top soil layer with a depth of 0 to 10 cm, the cation concentrations of Ca2+, Mg2+, and K+ has fallen significantly with the increase of tree ages. A higher concentration of exchangeable aluminum was observed in the soil with trees more seriously affected by the disease and was accompanied with lower concentrations of Ca2+, Mg2+, and K+. The correlation analysis showed that the soil pH is significantly positively related to the concentration of exchangeable Ca2+, total nitrogen, and total phosphorus and negatively to exchangeable aluminum. These findings provided a new insight to mitigate the disease by regulating the soil parameters.

“…10 Pi fertilizers are commonly used to improve plant growth and biomass in intensively managed bamboo forests, 11 but the excessive application of Pi fertilizers in the soil leads to eutrophication, soil acidification, 12 aluminum toxicity, and imbalanced ratios of mineral element in soil and bamboo, 13 ultimately leading to bamboo forest degradation. 14 This suggests that P stress is a significant problem for bamboo development. Hence, understanding the physiological, biochemical, and molecular changes under Pi stress in maintaining Pi homeostasis in moso bamboo will help to regulate phosphorus acquisition efficiency (PAE) and phosphorus use efficiency (PUE).…”

Both phosphate (Pi) deficiency and high Pi significantly affect moso bamboo growth and degrade bamboo forests. A novel plant hormone, strigolactone (SL), plays a crucial role in root growth under low Pi, but the SL regulatory mechanism has not been systematically reported in moso bamboo. In our study, we investigated the SL-mediated root growth mechanism in response to Pi stress in moso bamboo. With the decrease of the Pi level, 5-deoxystrigol and strigol significantly increased in the root exudates. Transcriptome sequencing of the primary root tip and lateral root primordium zone (LRP) under low, sufficient, and high Pi indicated that SL-biosynthesis and -signaling changes are part of the early root responses. The effects of the SL analogue (rac-GR24) and SL inhibitor (TIS108) on the root architecture under low and high Pi revealed that SL mediates bamboo root responses by regulating its biosynthesis and signal transduction and influencing other hormone pathways.

“…There is a widespread acknowledgement that traditional agricultural management is unsustainable, which threatens food security, results in land degradation, and reduces biodiversity [6,7]. Forest ecosystems represent the largest part of the terrestrial ecosystem, and intensive management of forests resulted in many ecological problems, such as soil acidification and nutrient imbalance [8,9]. Agroforestry is an alternative land-use system paradigm that intentionally integrates woody perennials with crops or livestock in the same land-managed fields [10].…”

Agroforestry has great potential for improving the ecological environment and raising the ecosystem productivity. This study is aim to evaluate the soil quality of bamboo forest and identify the main site factor that influencing the yield of Polygonatum tubers following the agroforestry practices. Four intercropping modes with different culm densities were conducted in Anhui, East China. The minimum data set method (MDS) was applied to evaluate soil quality index (SQI). Based on principal component analysis (PCA), microbial biomass carbon (MBC), available potassium (AK), altitude, and pH were selected as the MDS. The results showed that intercropping significantly increased SQI compared with moso bamboo monoculture. The mode M1(1750 culms/ha) was significantly better than other modes in improving soil fertility and increasing the yield of Polygonatum tubers. Results from random forest and structural equation model (SEM) showed the direct path coefficient of density on Polygonatum tubers yield was the largest, which was −0.83. Altitude, soil organic carbon (SOC) and nitrate nitrogen (NO3−-N) had a small impact, with direct path coefficient of 0.16, 0.10, and 0.15 (p < 0.05), respectively. Our findings provide a theoretical basis for managing the moso bamboo and P. cyrtonema agroforestry system in a more effective manner.
