海藻酸与化肥优化配施对设施连作番茄生长及养分吸收的影响
Effects of Alginic Acid and Fertilizer Combination on Growth and Nutrient Uptake of Continuous Cropping Tomato in Greenhouse
摘要
Abstract
To investigate the application effect of alginic acid extract solution in the soil of continuous cropping facilities,the soil from tomato fields with 20 consecutive crops was used as the experimental material.The alginic acid extract solution and chemical fertilizer were applied in combination at six different ratios.By analyzing tomato growth indicators,photosynthesis parameters,plant nutrient content,yield and quality,as well as changes in soil microbial communities,the optimal combined application ratio of alginic acid extract solution and chemical fertilizer was determined.The results demonstrated that the integrated application of alginic acid extract solution could effectively promote plant growth,enhance soil enzyme activity and microbial community structure,and improve crop yield and quality to varying extents while reducing the amount of chemical fertilizer applied.Notably,the T4 treatment(alginic acid extract solution∶chemical fertilizer=60％∶40％)exhibited the most significant effects,with markedly superior performance in terms of plant growth,photosynthetic parameters,soil nutrients,and fruit yield and quality compared to other treatments.These findings provide a theoretical foundation for partially substituting alginic acid extract solution for chemical fertilizers in tomato cultivation under continuous cropping conditions.关键词
