“…In this study, the application of vermicompost favored the survival of soil bacteria (Figure 2a,b), actinomycetes (Figure 2e,f), and reduced the number of soil fungi (Figure 2c,d) in two types of soil. This is also consistent with the previous research conducted by Pan et al (2019). Pan et al (2019) showed that vermicompost significantly increased the number of bacteria and actinomyces in continuous cropping soil, and reduced the number of fungi, which effectively alleviated the obstacle of continuous cropping soil.…”

Bupleurum falcatum L. (B. falcatum) has gained the attention due to its medicinal value in its root. B. falcatum was continuously cultivated and intensively chemically fertilized in order to attain a high yield, which reduced the soil quality and caused continuous cropping problems. Thus, there is significant impact on S. baicalensis yield and quality. To solve this problem, soil with 0 or 3 continuous cropping years (0‐year and 3‐year soil) was fertilized with several organic materials, that are Bacillus subtilis, Bacillus mucilaginosus, humic acid fertilizer, biochar, and vermicompost. The experiment examined the effectiveness of B. falcatum's growth and nutrient uptake under various organic materials. It was shown that organic materials improved soil fertility and promoted the growth and nutrient uptake of B. falcatum. The combination of vermicompost and biochar had a better improvement effect. It increased soil nutrients by 23.8%~73.3% (0‐year soil) and 24.6%~71.1% (3‐year soil), respectively. In two types of soil, both microbial number and enzyme activity substantially increased. The B. falcatum shoot and root biomass with vermicompost was increased 74.8%~84.5% (without biochar) and 41.8%~71.1% (with biochar) in two different types of soil. Vermicompost and biochar also significantly promoted the root development of B. falcatum. The root length increased by 13.3%~66.7%, the root width by 38.6%~84.8%, the root volume by 8.4%‐61.3%, and the specific root length varied by ‐171.9%~3.1%; as compared to the control. The nutrient (N, P and K) concentrations in shoots and roots changed ‐3.9%~67.2% and 1.4%~53.5%, respectively. All the findings demonstrated that long‐term continuous cropping caused cropping obstacles, deteriorated soil quality, and enhanced the B. falcatum growth. Applying organic fertilizers, such as vermicompost and biochar, can help to improve soil quality, increase soil nutrients, promote the growth and nutrients absorption of B. falcatum, and eliminate continuous cropping obstacles.

Apple replant disease (ARD) is common in apple production, which seriously affects the growth and development of apples. In this study, hydrogen peroxide with a bactericidal effect was used to treat the replanted soil, and the effects of different concentrations of hydrogen peroxide on replanted seedlings and soil microbiology were investigated in order to seek a green, clean way to control ARD. Five treatments were set up in this study: replanted soil (CK1), replanted soil with methyl bromide fumigation (CK2), replanted soil + 1.5% hydrogen peroxide (H1), replanted soil + 3.0% hydrogen peroxide (H2), and replanted soil + 4.5% hydrogen peroxide (H3). The results showed that hydrogen peroxide treatment improved replanted seedling growth and also inactivated a certain number of Fusarium, while the Bacillus, Mortierella, and Guehomyces also became more abundant in relative terms. The best results were obtained with replanted soil + 4.5% hydrogen peroxide (H3). Consequently, hydrogen peroxide applied to the soil can effectively prevent and control ARD.

Zinc is an important nutrient for several plants and humans. Nitric oxide (NO) is a free radical that is important to biological processes that mediate the growth and mitigation of biotic and abiotic stresses in plants. The present study investigated the enzymatic and photosynthetic profile and the accumulation of macro- and microelements in rice plants (Oryza sativa L.) that received foliar treatments of zinc oxide nanoparticles (ZnO NPs), nitric oxide donor (GSNO), and the association of both (GSNO–ZnO NPs). Zinc concentration in rice husks increased by 66% and 68% in plants treated with ZnO NPs and GSNO–ZnO NPs, respectively. The GSNO treatment caused an increase of 25% in the Fe concentration in the rice grains. Only a small disturbance of the antioxidant system was observed, with increases in H2O2, S-NO, and NO2−, mainly in the group treated with GSNO–ZnO NPs; however, the disturbance did not affect the yield, the growth, or vital processes, such as as photosynthetic pigments production. There was an increase in chlorophyll B of 290% and an increase in chlorophyll A of 187% when ZnO NPs was applied. GSNO–ZnO NPs increased chlorophyll B by 345% and chlorophyll A by 345%, indicating that the treatments GSNO, ZnO NPs, and GSNO–ZnO NPs reduced possible oxidative stress and helped as protective treatments.
