Soil acidification in tea plantation seriously reduced the yield and quality of tea. It was an effective method to use organic fertilizer for acidified soil remediation ensure quality. In this study, different fertilizers were used treat soils 4 consecutive years analyze effect on their effects The results showed that during period 2017-2021, pH value (S1) with long-term chemical decreased continuously, from 3.07 2.82. (S2), stable between 4.26 4.65 combination a long time. (S3) has 5.13...
This paper investigates the pull-in instability of nano-switches subjected to an electrostatic force due applied voltage and intermolecular within framework nonlocal elasticity theory account for small scale effect. Both nonlinear governing equation boundary conditions with effect are derived. A linear distributed load model is proposed approximate interactions. Closed-form solutions critical parameters obtained cantilever fixed–fixed nano-beams. The freestanding behaviour nano-beams, which...
In this study, sheep manure fertilizers with different dosages were used for five consecutive years to treat acidified tea plantation soils, and the effects of fertilizer on soil pH value, nitrogen transformation, yield quality analyzed. The results showed that value an increasing trend after a continuous use from 2018 2022. After low dosage (6 t/hm2-15 t/hm2), yield, content indicators (tea polyphenols, theanine, amino acid, caffeine) ammonium content, ammoniating bacteria number,...
Acidification can seriously affect the growth of tea trees and yield quality leaves. In this study, we analyzed effects acidification on physicochemical properties, microorganisms metabolites rhizosphere soils with different pH values, results showed that increase soil pH, organic matter content, cation exchange capacity, microbial biomass carbon, nitrogen, respiration intensity, bacterial number actinomyces in all an increasing trend, while fungi decreased. The metabolite analysis 2376,...
Magnesium (Mg) is one of the essential elements for growth tea tree and extremely important its development. In this study, we investigated effect Mg on transcriptome physicochemical indexes leaves, results showed that could significantly affect gene expression leaves. The Orthogonal Partial Least-Squares Discriminant Analysis (OPLS-DA) model analysis a total 300 key genes (Variable Importance Projection, VIP > 1) were screened under different concentrations treatment, among which 140...
Wuyi Rock tea is one of well-known in China. The 'Spring Tea Competition' every year a big event industry Wuyishan City. In this paper, 667 samples with four grades Rougui teas from Competition, 2019' were collected to determine quality indexes. relationship between the index and was analyzed. results showed that higher grade teas, total score (TQS) sensory evaluation. Most indexes had same tendency TQS. contents polyphenols, soluble sugar, catechins significantly different teas. PCoA could...
Withering is very important to the quality of Wuyi rock tea. In this study, transcriptomics and metabolomics were used analyze effects different withering methods on tea formation. The results showed that sunlight (SW) was most beneficial in increasing gene expression ubiquinone other terpenoid-quinone biosynthesis (ko00130), pyruvate metabolism (ko00620), starch sucrose (ko00500), tryptophan (ko00380) pathways, content nucleotides derivatives, terpenoids, organic acids lipids, thus...
In order to investigate the effect of pruning on soil environment in which tea trees grow and growth trees, this study used Wuyi Meizhan (Camellia sinensis) as a research object measured its indexes, physicochemical enzyme activity microbial functional diversity analyze effects treatments correlation between them. The results analysis tree indexes showed that hundred-bud weight, leaf area yield treatment were significantly higher than those unpruned treatment. index pH, available phosphorus,...
Soil acidification in Chinese tea plantations is widespread, and it has significantly affected the growth of trees; was important to explore soil remediation acidified depth for sustainable development industry. In this study, effects sheep manure fertilizer with different application depths on acidification, yield quality, nitrogen transformation were analyzed five consecutive years from 2018 2022. The results showed that long-term use reduced ( P < 0.05) plantations, improved pH...
In order to fully comprehend the impact of soil acidification on quality tea, further analyses are essential and utmost importance cultivation tea trees simultaneous enhancement quality. May 2022, Tieguanyin planted in soils with different pH levels were selected as research object this study analyze effect chemical index, fertility aroma leaves. The results showed that organic matter content, cation exchange capacity available nitrogen, phosphorus potassium contents rhizosphere decreased...
Functionally graded shape memory alloy (FG-SMA) hold considerable promise for diverse applications in aerospace and micro electro mechanical system (MEMS) fields, owing to their elevated ceramic hardness distinctive phase transition characteristics. To investigate the properties behaviors of FG-SMA, an FG-SMA specimen was fabricated first time using spark plasma sintering ball-mill mixing method. Subsequently, microstructure, transformation, hardness, compression fracture effect testing...
Magnesium (Mg) is one of the essential elements for growth tea trees. In this study, we investigated changes in metabolites, photosynthetic fluorescence parameters and quality indexes leaves under different concentrations magnesium treatment, results showed that there were no significant differences quantity total content metabolites Mg concentrations.
