Effects of Microbial Fertilizers in Improving Acidic Tobacco-planting Soil and Tobacco Leaf Quality

[Objectives]This study was conducted to improve acidic soil and enhance the quality of tobacco leaves.[Methods]The effects of different microbial fertilizers on improving acidic tobacco-planting soil and tobacco leaf quality were investigated through plot experiments.[Results]The application of microbial fertilizers could improve the pH value of acidic soil,and composite microbial agent A showed the best application effect.The application of bio-organic fertilizer was beneficial to improving the contents of available phosphorus and available boron in acidic soil.The application of composite microbial agent A was beneficial to improving the contents of available phosphorus and available potassium in acidic soil,and could promote the growth of tobacco plants and improve the economic traits of flue-cured tobacco and the coordination of chemical components in tobacco leaves.The application of composite microbial agent B led to a downward trend in the content of available boron in acidic soil.The application of composite microbial agent B could promote the absorption of nutrients by tobacco plants,and improve their disease resistance and the quality of tobacco leaves.Due to the differences in functional microorganisms contained,the application effects of different microbial fertilizers in improving acidic tobacco-planting soil and improving tobacco leaf quality varied.Overall,the application of microbial fertilizers could increase soil pH,activate soil nutrients,promote tobacco growth,enhance disease resistance,increase tobacco output value,and improve tobacco quality.Microbial fertilizers have good application prospects in improving acidic soil and improving tobacco quality.[Conclusions]The application of microbial fertilizers to improve acidic tobacco-planting soil can ensure the normal growth and development of tobacco plants and the improvement of tobacco leaf quality,achieving high-quality and sustainable development of Zhaotong tobacco.

Blood flow restriction training improves the efficacy of routine intervention in patients with chronic ankle instability

As a new means of rehabilitation,blood flow restriction training(BFRT)is widely used in the field of musculoskeletal rehabilitation.To observe whether BFRT can improve the efficacy of routine rehabilitation intervention in patients with chronic ankle instability(CAI).Twenty-three patients with CAI were randomly divided into a routine rehabilitation group(RR Group)and a routine rehabilitationþblood flow restriction training group(RRþBFRT Group)according to the Cumberland Ankle Instability Tool(CAIT)score.The RR Group was treated with routine rehabilitation means for intervention,and the RRþBFRT Group was treated with a tourniquet to restrict lower limb blood flow for rehabilitation training based on routine training.Before and after the intervention,the CAIT score on the affected side,standing time on one leg with eyes closed,comprehensive scores of the Y-balance test,and surface electromyography data of tibialis anterior(TA)and peroneus longus(PL)were collected to evaluate the recovery of the subjects.Patients were followed up 1 year after the intervention.After 4 weeks of intervention,the RRþBFRT Group CAIT score was significantly higher than the RR Group(19.33 VS 16.73,p<0.05),the time of standing on one leg with eyes closed and the comprehensive score of Y-balance were improved,but there was no statistical difference between groups(p>0.05).RRþBFRT Group increased the muscle activation of the TA with maximum exertion of the ankle dorsal extensor(p<0.05)and had no significant change in the muscle activation of the PL with maximum exertion of the ankle valgus(p>0.05).There was no significant difference in the incidence of resprains within 1 year between the groups(36.36%VS 16.67%,p>0.05).The incidence of ankle pain in the RRþBFRT Group was lower than that in the RR Group(63.64%VS 9.09%,p<0.01).Therefore,four-weeks BFRT improves the effect of the routine intervention,and BFRT-related interventions are recommended for CAI patients with severe ankle muscle mass impairment or severe pain.
