“…This study found that, in soils without CP fumigation, AZO application did not affect soil phosphatase activity until 28 WAP, which may be caused by the low application rate of AZO (0.55 mg kg −1 ) and rapid degradation rate. 25 This result was also in line with a previous study conducted by Wang et al,33 who discovered that the application of AZO at a rate of 2.0 mg kg −1 had no significant effect on the phosphatase activity on the 7th day of incubation in Spodosols. Similarly, in our study, soil samples were collected 1 week after the AZO application.…”

“…In addition, our previous study discovered that only CP fumigation combined with double application of AZO increased the ginger height and root P uptake, while a single application of AZO did not affect the ginger growth regardless of whether CP fumigation was applied. 25 Therefore, in this study, we want to go further in exploring the variations in soil phosphatase activity and soil P fractions under the combined application of CP fumigant and AZO fungicide, and try to answer whether CP and AZO application could change the soil P availability. The study was conducted using the same greenhouse experiment as our previous study, 25 in which CP and AZO were applied individually and in combination.…”

BACKGROUNDSoil fumigation can change soil nutrient cycling processes by affecting soil beneficial microorganisms, which is a key issue for soil fertility. However, the effect of combined application of fumigant and fungicide on soil phosphorus (P) availability remains largely unclear. We investigated the effects of the fumigant chloropicrin (CP) and the fungicide azoxystrobin (AZO) on soil phosphatase activity and soil P fractions in ginger production using a 28‐week pot experiment with six treatments: control (CK), a single application of AZO (AZO1), double applications of AZO (AZO2), CP‐fumigated soil without AZO (CP), CP combined with AZO1 (CP + AZO1) and CP combined with AZO2 (CP + AZO2).RESULTSAZO application alone significantly increased the soil labile P fractions (Resin‐P + NaHCO3‐Pi + NaOH‐Pi) at 9 weeks after planting (WAP) but decreased the soil phosphatase activity at 28 WAP. CP fumigation significantly reduced the soil phosphatase activity but increased the proportions of soil labile P fractions (Resin‐P + NaHCO3‐Pi + NaHCO3‐Po) to total P (TP) by 9.0–15.5% throughout the experiment. The combined application of CP and AZO had a synergistic effect on soil phosphatase activity and soil P fractions compared with a single application.CONCLUSIONAlthough AZO application and CP fumigation can increase soil available P in the short term, they might negatively affect soil fertility in the long run by inhibiting soil phosphatase activity. Soil microbial activities, especially microorganisms related to P cycling, may be responsible for the variations in soil P availability, but further research is needed. © 2023 Society of Chemical Industry.

“…Azoxystrobin (AZO) is a fungicide which inhibits fungi by disrupting ATP production in fungal mitochondria (Sun et al, 2018). Wang et al (2022) found that application of appropriate AZO combined with chloropicrin fumigation could promote the growth and phosphorus amount of ginger rhizomes. RNA-Seq has become an indispensable tool for transcriptome-wide analysis of differential gene expression and differential splicing of mRNAs in the past decade (Stark et al, 2019).…”

Codonopsis tangshen Oliv (C. tangshen) is an important Chinese traditional medicinal plant with various health benefits. However, the growth of C. tangshen are seriously affected by continuous cropping, which led to the decrease of the yield and quality. A field experiment was conducted to learn the effects of soil amendments on the growth of C. tangshen under continuous cropping condition, and the biological events which occurred at molecular level were investigated. The results indicated that the content of chlorophyll a (Chl a), chlorophyll b (Chl b), and carotenoid (Car) was significantly higher in SCPM (silicon-calcium-potassium-magnesium fertilizer), SCPMA (SCPM combined with azoxystrobin) and SCPMAOM (SCPM combined with azoxystrobin and organic manure) treatments. Moreover, the yield and the levels of alkaloid, polysaccharide, flavone and total protein in the treatments of SCPM, SCPMA and SCPMAOM were significantly higher than those in the control, and these indexes were all highest in the SCPMAOM treatment. RNA-sequencing (RNA-Seq) is an economical and efficient method to obtain genetic information for species with or without available genome data. In this study, RNA-Seq was performed to understand how continuously cropped C. tangshen responded to the soil amendments at the transcriptome level. The number of differentially expressed genes (DEGs) were as follows: CK vs. SCPM (719 up- and 1456 down-), CK vs. SCPMA (1302 up- and 1748 down-), CK vs. SCPMAOM (1274 up- and 1678 down-). The soil amendments affected the growth of C. tangshen mainly by regulating the genes involved in pathways of ‘photosynthesis,’ ‘plant hormone signal transduction,’ ‘biosynthesis of unsaturated fatty acids,’ ‘phenylpropanoid biosynthesis,’ and ‘starch and sucrose metabolism,’ etc. qRT-PCR was performed to validate the expressions of 10 target genes such as CP26, PsaF, and POX, etc., which verified the reliability of RNA-Seq results. Overall, this study revealed the roles and underlying mechanisms of the soil amendments in regulating the growth of continuously cropped C. tangshen at transcriptome level. These findings are beneficial for improving the continuous cropping tolerance and may be valuable for future genetic improvement of C. tangshen.

“…The deeper the fumigants are applied, the more efficient they are at controlling soil-borne diseases (Yan et al, 2017a). Typically, regardless of the application method, fumigated soils need to be immediately covered with plastic films to create an enclosed soil space to prevent emission of fumigants into the air (Wang et al, 2022a). A more impermeable film can reduce the emission of fumigants, thereby improving the inhibitory effects of the fumigant on soil-borne pathogens.…”
