腐植酸复合肥对番茄产量和品质的影响

Effects of the Humic Acid Compound Fertilizer on Yield and Quality of the Tomato

以腐植酸复合肥作为番茄底肥研究了其对番茄产量和品质的影响。结果表明:腐植酸复合肥对提高番茄产量和品质都有显著效果。腐植酸复合肥处理对番茄株高、茎粗、叶面积和叶绿素值均产生促进作用,但如果含量超过一定范围则会使促进增长效果降低。腐植酸复合肥处理协调了番茄产量构成因素之间的相互关系,改善了番茄后期养分的营养水平,从而增加了番茄产量。腐植酸复合肥可提高可溶性固形物、粗蛋白、维生素C、可溶性糖和糖酸比,并能降低硝酸盐含量来提高番茄品质。

Humic acid compound fertilizer as base fertilizer was taken to study the effect of yield and quality of the tomato.The results showed that acid compound fertilizer could increase the yield and improve the quality of the tomato.It could increase the stem height,stem diameter,leaf area and chlorophyll value.But It lowered the effect beyond a certain amount.It could coordinate the mutual relation among forming factors of yield,improve the nutrition level in later stage of the tomato,therefore,increase the yield of tomato.It could increase the contents of soluble solid,crude protein,Vc,soluble sugar,and the ratio of sugar and acid.It could lower the content of nitrate.
