Effect of Various Mulch Materials on Chemical Properties of Soil, Leaves and Shoot Characteristics in Dendrocalamus Latiflorus Munro Forests

Abstract

The effectiveness of mulch treatments on soil quality as well as on the yield and growth rates of bamboo are major considerations and require further attention. The present work was aimed at assessing the impacts of three different mulch materials on soil available nutrients, biochemical traits, and growth patterns of Dendrocalamus latiflorus Munro. We found that relative to the control (CK), bamboo leaves (MB) and organic fertilizers (MF) treatments significantly (P < 0.05) increased the number of bamboo shoots (47.5 and 22.7%) and yield (21.4 and 9.1%), respectively. We observed that under MB and MF treatments, the concentrations of soil available nutrients (nitrogen, phosphorus, and potassium) increased and played a key role in the differences in chlorophyll, leaf carbohydrate contents (soluble sugar and starch) and were essential to promote bamboo shoot development. Furthermore, we infer from principal component analysis (PCA), that both MB and MF appear to be a better choice than rice husks (MR) to improve nutrient availability, biochemical traits of the leaves, and increased bamboo shoot productivity. Consequently, we suggest using organic fertilizers and bamboo leaves as mulch materials are effective for soil conservation to attain high-quality bamboo production.

Effects of Low-Light Environments on the Growth and Physiological and Biochemical Parameters of Indocalamus and Seasonal Variations in Leaf Active Substance Contents

“…Indocalamus plants have low growth rates, and their growth is affected by environmental influences, particularly light intensity [30]. The period in which new bamboo is generated is an essential stage in the bamboo growth cycle, and the rate of new bamboo generation is one of the most significant indicators for assessing the reproductive ability of bamboo plants [31]. In the present study, the reduction in the new bamboo rate of some Indocalamus species under the ST treatment compared with that under the CK treatment may be due to the effect of the low light availability on the photosynthetic carbon sequestration capacity of leaves at the late stage of new shoot growth, leading to insufficient nutrient resources for the generation of new bamboo [32].…”

Tissue-cultured regeneration and ecological values in major bamboo species

“…Possible concentrations of organic and inorganic chemicals can be applied to the soil for the acclimatization or adaptation of bamboo species are shown in Table 2 (Azeez and Orege 2018;Kaushal et al 2020;Kranz et al 2020;Lin et al 2019;Rajput et al 2019;Zubrod et al 2019). The concentrations of chemicals enhance the duration of acclimatization and adaptation in bamboo species (do Vale et al 2019;Fan et al 2021). The chemically enriched soil water is transported in the bamboo species for natural adaptation in the relevant time duration (Hussain and Abbasi 2018).…”

Significant Effects of Long-Term Application of Straw and Manure Combined with NPK Fertilizers on Olsen P and PAC in Red Soil

“…Long term application of P fertilizers combined with manure or straw is a commonly used fertilization method in soil, which could continuously increase the Olsen P and PAC [1][2][3]. Olsen P is the most effective for crops, but it is prone to loss, especially in the red soil areas with high rainfall in Southern China [3,4].…”

“…Long term application of P fertilizers combined with manure or straw is a commonly used fertilization method in soil, which could continuously increase the Olsen P and PAC [1][2][3]. Olsen P is the most effective for crops, but it is prone to loss, especially in the red soil areas with high rainfall in Southern China [3,4]. Therefore, elucidating the differences in Olsen P and PAC under P surplus after applying manure and straw is crucial for selecting a reasonable fertilization method.…”
