摘要
为探明生物腐殖酸对番茄植株生长性状、果实产量和品质及土壤养分含量的影响,本研究以金陵露比番茄品种为试验材料,设置3个处理:对照、每株根施生物腐殖酸37.5 mg、每株根施生物腐殖酸150.0 mg。结果表明,根施生物腐殖酸可以显著促进番茄植株生长,明显改善果实品质,当生物腐殖酸施用水平为每株150.0 mg时,番茄部分生长性状指标、产量和品质指标(番茄红素含量除外)最佳。与对照相比,生物腐殖酸施用量为每株150.0 mg时,番茄植株的株高、茎粗、SPAD值显著提高,果实单株产量、单位面积产量明显提升,果实维生素C含量、可溶性糖含量、可溶性蛋白含量显著增加。生物腐殖酸施用对总氮、速效磷、有效钾、有机质等土壤养分含量无显著影响。综合考虑各项指标,每株根施生物腐殖酸150.0 mg对番茄植株生长和果实发育促进效果最显著。
To explore the effects of biological humic acid(BHA)on tomato plant growth characteristics,fruit yield and quality,and nutrient content of soil,this study used Jinling Ruby tomato as the experimental material,and set up three treatments:control,root application of BHA at 37.5 mg per plant,root application of BHA at 150.0 mg per plant.The results showed that root application of BHA could significantly promote tomato plant growth and improve fruit quality.When the application level of BHA was 150.0 mg per plant,the indices of some growth traits,yield and quality indices(except lycopene content)of tomato were the best.Compared with the control,the plant height,stem diameter and SPAD value at 150.0 mg per plant application level were significantly improved,the fruit weight per plant and the yield per square meter were significantly improved,and the contents of vitamin C,soluble sugar and soluble protein in fruits were significantly increased.The application of BHA had no significant effect on the content of soil nutrients such as total nitrogen,available phosphorus,available potassium and organic matter.Taking all indicators into account,root application of 150.0 mg BHA per plant had the most significant effect on promoting the growth of tomato plant and fruit development.
