ObjectiveTo investigate the effects of foliar fertilizer of nano-calcium carbonate and calcium nitrate tetrahydrate on the agronomic traits, carbohydrate and endogenous hormone contents of Dendrobium officinale planted for 1 year under greenhouse cultivation, in order to provide scientific basis for fertilization to improve the yield and quality of D. officinale. MethodsSingle-factor experimental design was adopted. Starting from early spring, D. officinale was treated with foliar spraying according to corresponding fertilizers. Three treatment groups were established based on different fertilizers, namely, a blank group(clear water), a nano-calcium carbonate group(0.727 g·L-1 nano-calcium carbonate water-soluble fertilizer), and a calcium nitrate tetrahydrate group(1.091 g·L-1 calcium nitrate tetrahydrate water-soluble fertilizer). The frequency of spraying was three times per month, and the entire treatment process lasted for nine months. The effects of various treatments on the traits and relative chlorophyll content of D. officinale were dynamically monitored. Sampling was conducted at three specific time points:August 2, 2023, September 8, 2023, and November 1, 2023, respectively. The contents of glucose and mannose in D. officinale stems were determined by high performance liquid chromatography(HPLC), the content of soluble sugars in D. officinale stems and leaves was determined by phenol method, and enzyme-linked immunosorbent assay(ELISA) was used to detect the concentrations of cytokinin and auxin. ResultsCompared with the blank group, the treatments with nano-calcium carbonate and calcium nitrate tetrahydrate could significantly increase stem length, stem node number, leaf number, and tiller number. Among them, during the harvesting period in November, the stem length and tiller number, which are indicators related to the yield of D. officinale, increased by 60.85% and 19.23% after treatment with calcium nitrate tetrahydrate, and by 32.54% and 28.85% after treatment with nano-calcium carbonate, respectively. Compared with the blank group, treatments with nano-calcium carbonate and calcium nitrate tetrahydrate could promote the accumulation of sucrose in the stems and leaves of D. officinale to varying degrees, as well as the accumulation of polysaccharides, mannose, and glucose in the stems. In addition, nano-calcium carbonate treatment also facilitated the accumulation of fructose in the stems and leaves of D. officinale. Specifically, during the harvesting period in November, polysaccharides and mannose, which were the main active ingredients in D. officinale stems, increased by 28.48% and 29.36% after treatment with calcium nitrate tetrahydrate, and by 39.91% and 82.62% after treatment with nano-calcium carbonate, respectively. In addition, compared with the blank group, the concentrations of auxin in the stems and leaves of D. officinale were significantly increased after treatment with calcium nitrate tetrahydrate(P<0.05). Similarly, the concentrations of cytokinin and auxin in the stems of D. officinale were also elevated after treatment with nano-calcium carbonate. Correlation analysis further indicated that elongation growth and tillering of D. officinale stems after foliar spraying of nano-calcium carbonate and calcium nitrate tetrahydrate might be related to the accumulation of carbohydrates in the stems and leaves and the synergistic effect of auxin and cytokinin. ConclusionIn production practice, spraying nano-calcium carbonate and calcium nitrate tetrahydrate can promote the accumulation of cytokinin, auxin, and carbohydrate contents in the stems and leaves of D. officinale, and promote tillering and elongation growth of the stems.

Working memory is an executive memory process that includes encoding, maintenance, and retrieval. These processes can be modulated by transcranial alternating current stimulation (tACS) with sinusoidal waves. However, little is known about the impact of the rate of current change on working memory. In this study, we aimed to investigate the effects of two types of tACS with different rates of current change on working memory performance and brain activity. We applied a randomized, single-blind design and divided 81 young participants who received triangular wave tACS, sinusoidal wave tACS, or sham stimulation into three groups. Participants performed n-back tasks, and electroencephalograms were recorded before, during, and after active or sham stimulation. Compared to the baseline, working memory performance (accuracy and response time) improved after stimulation under all stimulation conditions. According to drift-diffusion model analysis, triangular wave tACS significantly increased the efficiency of non-target information processing. In addition, compared with sham conditions, triangular wave tACS reduced alpha power oscillations in the occipital lobe throughout the encoding period, while sinusoidal wave tACS increased theta power in the central frontal region only during the later encoding period. The brain network connectivity results showed that triangular wave tACS improved the clustering coefficient, local efficiency, and node degree intensity in the early encoding stage, and these parameters were positively correlated with the non-target drift rate and decision starting point. Our findings on how tACS modulates working memory indicate that triangular wave tACS significantly enhances brain network connectivity during the early encoding stage, demonstrating an improvement in the efficiency of working memory processing. In contrast, sinusoidal wave tACS increased the theta power during the later encoding stage, suggesting its potential critical role in late-stage information processing. These findings provide valuable insights into the potential mechanisms by which tACS modulates working memory.
