“…Intensive management with organic material mulching is a special mode of bamboo industry, especially in the Zhejiang province of China [ 7 ]. This management is mulched with rice husk or straw with a thickness of 30 cm, largely reducing the oxygen content of the soil layer to 7% during intensive management of the Phyllostachys praecox forest [ 8 ]. Despite that aeration of covered Phyllostachys praecox can be positively against this effect [ 9 ], there were few reports on the effect of oxygen deficiency on growth and response of Phyllostachys praecox .…”

Hypoxia affects plant growth, hormone content, various enzyme activities, cell structure, peroxide production, and metabolic level, therefore reducing crop yield. This study assessed the physiological, biochemical, and metabolic characteristics of Phyllostachys praecox. Results revealed that hypoxia stress treatment significantly inhibited plant growth. Leaf chlorophyll contents was initially improved and then reduced with plant growth time. Under hypoxia stress, the root activity significantly was reduced, leading to the decrease in the nutrient absorption and transport. Yet, with low oxygen concentration, the contents of ethanol, acetaldehyde, and lactic acid were improved. With hypoxia stress, phospholipids and amino acids were the main metabolites of Phyllostachys praecox. Glycosphospholipid metabolism is the key pathway in responding to hypoxia stress significantly (p < 0.05), and lysophosphatidlycholine (lysoPC) and phosphatidylcholines (PC) in the metabolites of this metabolic pathway were significantly enhanced. Our study reveals the mechanism of Phyllostachys praecox cell membrane responding to hypoxia stress based on molecular level. This is conducive to finding targeted solutions to improve the productivity of Phyllostachys praecox to better optimize a mulching approach in the bamboo forest.

“…Organic mulching is a common technique used in agriculture (Qian et al, 2021). The mulch covering can reduce evaporation and regulate soil temperature, which offers multiple benefits to crop development and production (Liu et al, 2016; Zhong et al, 2018).…”

“…To obtain the edible shoots of P. praecox relatively early in winter, mulching is widely applied in combination with organic fertilizer (Gui et al, 2020; Liu et al, 2016). Mulching can lead to soil erosion, soil acidification, and soil hypoxia, thereby negatively affecting bamboo plantation development (Ni et al, 2021; Qian et al, 2021). Mulching can also beneficially influence soil microbial community structure, with mulch materials offering abundant substrate for soil microorganisms (Elliott Ronald et al, 2016).…”

“…Therefore, fungi potentially play important roles in nutrient transformation and soil ecosystem sustainability in P. praecox plantations. But the effects of organic mulching on the microbial microenvironments can be complex, especially the fermentation of organic materials under mulching conditions could increase soil O 2 consumption and aggravate hypoxia stress (Qian et al, 2021), with potential effects on soil fungal community structure. It is worth note that that researchers have reported that irrigation and soil compaction influence fungal community structure considerably (Miransari, 2013; Buil et al, 2021; Romero‐Trigueros et al, 2021; Rosas‐Medina et al, 2020).…”

Aeration can alleviate soil hypoxia stress of Phyllostachys praecox bamboo under mulching conditions, but how aeration affects soil properties, soil fungal community structure, and bamboo development is unclear. We studied the responses of soil properties, fungal community structure, bamboo shoots, and rhizome growth to organic mulching (TM), mulching with aeration (TA1 and TA2), and no‐mulching treatments (CK) from a field experiment in March and July, 2019. During the mulching period (March), the aeration improvement treatment (TA2) improved soil O2 content, bamboo shoots yield, and soil nutrient availability significantly when compared with TM. TA2 treatment showed significantly higher relative abundances of the genus Trichoderma and functional group endophyte than TM treatment, which might be conducive to soil nutrient transformation and bamboo growth. The TA2 treatment had higher fungal diversity indices than that of the TA1 treatment, suggesting that optimal aeration conditions enhance soil fungal diversity. The fungal community structure also showed strong temporal dynamics in all treatments. Mantel test results indicated soil O2 is the primary factor driving fungal community structure under mulching conditions, while has no impact on the fungal community in summer; fungal community structure was primarily controlled by soil pH in summer. Structural equation model revealed soil NO3−‐N content was responsible directly for bamboo rhizome growth and shoot yield. Our results indicate short‐term mulching is beneficial to soil nutrients improvement and bamboo yield increase, while rational aeration can further facilitate sustainable plantation development under hypoxic soil conditions.

“…Since its shoots are edible by humans, P. praecox is a favored species, and because of its high economic returns, P. praecox plantations are now extensively cultivated in southern China [25]. Intensive management techniques for its cultivation there include organic material mulching, heavy fertilization, and the application of organic manure, all of which are commonly used to increase soil temperatures in winter so as to stimulate the early emergence of bamboo shoots and obtain a premium price when the market supply is low [26]. As reported by other researchers, mulching can foster soil organic matter accumulation and lead to soil acidification, as well as bamboo recession [27][28][29].…”

The mineralization of soil organic nitrogen (N) is the key process in the cycling of N in terrestrial ecosystems. Land-use change to bamboo (Phyllostachys praecox) cultivation that later entails organic material mulching combined with chemical fertilizer application will inevitably influence soil N mineralization (Nmin) and availability dynamics. However, the soil Nmin rates associated with various N fractions of P. praecox in response to land-use change and mulching are not well understood. The present study aimed to understand the effects of land-use change to P. praecox bamboo cultivation and organic material mulching on soil Nmin and availability. Soil properties and organic N fractions were measured in a P. praecox field planted on former paddy fields, a mulched P. praecox field, and a rice (Oryza sativa L.) field. Soil Nmin was determined using a batch incubation method, with mathematical models used to predict soil Nmin kinetics and potential. The conversion from a paddy field to P. praecox plantation decreased the soil pH, soil total N, and soil organic matter (SOM) content significantly (p < 0.05); the mulching method induced further soil acidification. The mulching treatment significantly augmented the SOM content by 7.08% compared with the no-mulching treatment (p < 0.05), but it decreased soil hydrolyzable N and increased the nonhydrolyzable N (NHN) content. Both the Nmin rate and cumulative mineralized N were lowest in the mulched bamboo field. The kinetics of Nmin was best described by the ‘two-pool model’ and ‘special model’. The Pearson’s correlation analysis and the Mantel test suggested soil pH was the dominant factor controlling the soil cumulative mineralized N and mineralization potential in the bamboo fields. These findings could help us better understand the N cycling and N availability under mulching conditions for shifts in land use, and provide a scientific basis for the sustainable management of bamboo plantations.
