腐植酸钾和氨基酸肥料对砂培番茄生长与果实品质的影响
Effects of Potassium Humate and Amino Acid Fertilizer on Growth and Fruit Quality of Sand Tomatoes
摘要
Abstract
Using tomato as experimental material and using sand cultivation method,the effects of exogenous ad-dition of potassium humate and amino acid fertilizer on the metabolic pathway,plant biomass,nutrient uptake,yield and quality index of tomato at seedling stage were explored.The experimental results showed that:the root growth of tomato increased by 118%and 13%at the seedling stage and flowering and fruiting stage under potassium humate treatment,and the nitrogen,phosphorus and potassium carrying in the stem increased significantly by 31%,45%and 26%.The amount of phosphorus carried out in leaves increased significantly by 92%.Phosphorus carrying from fruit also increased significantly by 45%.The metabolomic results showed that potassium humate treatment mainly affected tomato glutathione metabolism,glycine serine and threonine metabolism,porphyrin and chlorophyll metabolism,while amino acid fertilizer treatment mainly affected tomato propionic acid metabolism,pantothenic acid and coenzyme A bi-osynthesis and TCA cycling.Compared with the blank control,the yield of tomatoes under potassium humate treatment increased by 35%,the fresh weight and dry weight of the aboveground increased by 21%and 5%,and the soluble sugar content,sugar-acid ratio and soluble solids content in tomato fruits were also significantly increased,with increa-ses of 30%,41%and 0.39 percentage point,respectively.The application of amino acid fertilizer significantly in-creased the root length,aerial fresh weight and fruit yield of tomato during the flowering and fruiting stage,which in-creased by 19%,18%and 26%,respectively,and the soluble solids content of tomato fruit increased by 0.30 percent-age point,the solid-acid ratio increased by 16%,and the weight per fruit increased by 15.6%.In summary,the applica-tion of potassium humate and amino acid fertilizer can significantly change the carbon and nitrogen metabolism process of sand tomato plants,promote tomato growth and fruit quality,and is an effective agronomic measure to achieve high-yield and high-quality tomato cultivation.关键词
