微润灌下施用有机水溶肥对番茄生长的影响
Effects of Organic Water-Soluble Fertilizer Application on Tomato Growth Under Micro-Irrigation
摘要
Abstract
Under solar greenhouse conditions,this study investigated the effects of different types of organic water-soluble fertilizers at three application concentrations on tomato growth,fruit quality,and water-fertilizer use efficiency,using micro-irrigation technology.Four types of organic water-soluble fertilizers were evaluated:mineral-source potassium fulvic acid(T1),humic acid(T2),chitosan seaweed extract(T3),and Qicai Wogen(T4),each applied at low(C1:150 kg/hm²),medium(C2:225 kg/hm²),and high(C3:300 kg/hm²)concentrations.An unfertilized treatment(CK)was used as the control.Growth parameters,quality indicators,and water-fertilizer use efficiency were measured.Ridge regression analysis was performed to assess the relationships between growth and quality indicators and tomato yield,while comprehensive evaluation was conducted using the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)method.The results showed that all levels of organic water-soluble fertilizer application promoted tomato growth and improved fruit quality compared with the control,with medium concentration treatments producing the most favorable outcomes.Under medium concentration treatments,plant height,stem diameter,leaf area,and SPAD values increased by 61.43%～99.33%、25.47%～44.03%、39.98%～52.39%and 15.16%～23.06%,respectively,compared with CK.Yield increased by 14.88%～39.65%,water use efficiency increased by 2.21%～39.29%,while soluble sugar,lycopene,and vitamin C contents increased by 8.17%～21.76%、38.17%～84.47%and 106.05%～160.93%,respectively.The partial factor productivity of fertilizer in each treatment showed a decreasing trend with the increase in fertilization concentration.Ridge regression analysis indicated that stem diameter and leaf area had the strongest positive correlations with yield,whereas lycopene content showed a significant negative association.Significant differences were observed among fertilizer types and application concentrations in their effects on tomato growth and quality.The comprehensive evaluation revealed that the T4C2 treatment ranked highest in the TOPSIS analysis(score:0.828),demonstrating superior performance in terms of fruit quality,yield,and resource use efficiency,and can be recommended as an optimal strategy for improving tomato water and fertilizer management.关键词
