“…This technology can promote the early emergence of bamboo shoots and increase yield, thereby significantly improving the associated economic benefits. However, the long-term application of chemical fertilizers can easily lead to the degradation of the bamboo forest ecosystem, resulting in declining fertility, soil erosion, a reduction in microbial community diversity, and the eutrophication of water systems, seriously hindering the sustainable development of bamboo forest populations [1,[6][7][8]. Therefore, it is necessary to investigate the effects of reduced chemical fertilizer application on the productivity of Lei bamboo.…”

Lei bamboo (Phyllostachys praecox) is an economically viable bamboo species with rich nutrition, a good taste, and a high yield. However, heavy fertilization and covering cultivation are used to produce off-season bamboo shoots, resulting in soil degradation and a decline in site productivity. This study investigated how compound fertilizer decrement and water-soluble humic acid fertilizer application affects soil properties and shoot yield in Lei bamboo plantations of subtropical China. The soil nutrients, enzyme activities, and shoot yield were examined, the bacterial community structure was determined using the high-throughput sequencing method, and their relationships were evaluated under different fertilization treatments: single compound fertilizer and compound fertilizer decrement with water-soluble humic acid fertilizer applications. Compared with those after single compound fertilizer treatments (CF1, CF2), water-soluble humic acid fertilizer addition (CF2HA1, CF2HA2) increased soil organic carbon (SOC), available phosphorus (AP), microbial biomass nitrogen (MBN) contents, the ratio of SOC to total nitrogen (C/N), and sucrase and acid phosphatase (Acp) activities, and decreased alkali hydrolyzed nitrogen (AN) and microbial biomass carbon (MBC) contents. The bacterial community phyla comprised 83.62%–86.16% Proteobacteria, Acidobacteria, Bacteroidetes, Actinobacteria, and Chloroflexi. Water-soluble humic acid fertilizer application also significantly increased yields by over 30%. AP and MBN were important drivers affecting soil bacterial communities, whereas SOC, MBN, and Chloroflexi affected Lei bamboo shoots. Overall, compound fertilizer decrement and water-soluble humic acid fertilizer application shifted the available soil nutrients, sucrase and Acp activity, bacterial community diversity, and shoot yield. An improved understanding of humic acid and the application of humic acid water-soluble fertilizer are of great significance for soil improvement, ecological restoration, and the sustainable management of bamboo forests in the future.

Lei bamboo (Phyllostachys violascensʻPrevernalisʼ) is a high economic value species with high yield and good quality of bamboo shoots. However, heavy chemical fertilizer and covering cultivation are used to produce off-season bamboo shoots, resulting in soil degradation and a decline in soil productivity. This study introduced an amino acid fertilizer called fish protein fertilizer to replace part of chemical fertilizer, and investigated the effect of different fertilizer combinations on bamboo growth, shoot yield and soil properties to clarify the growth-promoting mechanism of amino acid fertilizer. Results showed that after replacing 45 kg of compound fertilizer with 10 kg or 20 kg of fish protein fertilizer (1) bamboo shoot yield increased by 23.24% or 26.19%, respectively; (2) growth of leaves and roots were enhanced, thick root proportion increased, and proportion of root in the topsoil layer decreased; (3) soil pH, contents of AP (available phosphate), SOC (soil organic carbon), MBC (microbial biomass carbon) and MBN (microbial biomass nitrogen), soil enzyme activity increased; (4) contents of N and P in leaf increased, while the N/P and K/P decreased. Overall, amino acid fertilizer can promote microbial growth and improve soil enzyme activity through supplying carbon sources and nitrogen sources, thus promoting phosphorus activation and increasing soil phosphorus effectiveness, and then improving the foraging scale of root systems, and ultimately enhancing nutrients absorption and increasing bamboo shoot yield.
