摘要
以番茄‘金鹏M6’为材料,采用盆栽试验方式,研究不同用量黄腐酸对番茄生长、养分吸收、碳氮代谢、产量及品质的影响。结果表明,黄腐酸用量为30 mg/kg时能促进苗期番茄植株生长,增加根系体积及表面积,促进植株氮磷钾养分吸收,提高可溶性蛋白、可溶性糖及谷氨酰胺合成酶含量,番茄各项指标达到最高值;与对照不施加黄腐酸相比,番茄可溶性糖和Vc分别增加了43.9%和35.4%,番茄产量提高28.1%。黄腐酸用量为3000 mg/kg时,番茄相关指标与对照相比无显著异。综合材料成本和各项指标,本研究推荐黄腐酸最佳用量为30 mg/kg。
In this study,tomato variety‘Jinpeng M6’was used as the material and pot experiments were conducted to study the effects of different amounts of fulvic acid on tomato growth,nutrient absorption,carbon and nitrogen metabolism,and yield and quality.The results showed that the dosage of fulvic acid at 30 mg/kg could promote the growth of tomato plants at the seedling stage,increase the root volume and surface area,promote the absorption of nitrogen,phosphorus and potassium,and increase the content of soluble protein,soluble sugar and glutamine synthase,and the indexes of tomato reached the highest value.Compared with the control(fulvic acid was not applied),soluble sugar and vitamin C in tomato increased by 43.9%and 35.4%,respectively,and tomato yield increased by 28.1%.When the amount of fulvic acid was 3000 mg/kg,there was no significant difference of tomato-related indexes between the treatment and the control.Based on material cost and various indexes,the optimal dosage of fulvic acid is 30 mg/kg.
