矿源黄腐酸钾与鱼蛋白配施在番茄上的应用效果

Application Effect of Mineral Based Potassium Fulvate Combined with Fish Protein on Tomato

在施用大量元素水溶肥的基础上,设置5个处理,分别为CK(对照),不添加矿源黄腐酸钾和鱼蛋白;T1:矿源黄腐酸钾10%+鱼蛋白40%;T2:矿源黄腐酸钾10%+鱼蛋白20%;T3:矿源黄腐酸钾10%+鱼蛋白10%;T4:矿源黄腐酸钾10%。研究各处理对番茄农艺性状和产量品质的影响。结果表明:番茄的生长指标,T1~T4处理的茎粗与CK相比分别显著增加17.07%、15.15%、11.53%和5.03%;各处理番茄SPAD值与CK相比差异不显著;T1~T4处理的单果重与CK相比分别显著增加24.62%、18.63%、14.62%和8.53%。T1~T4处理的产量与CK相比分别显著增加8.2%、6.6%、5.6%和3.8%。番茄的品质指标,可溶性固形物与总糖度表现相一致,与总酸度表现相反。T1~T4处理番茄糖酸比与CK之间有显著性差异,以T1处理最佳。T1~T4处理的番茄Vc含量与CK相比分别显著提高22.5%、18.1%、14.8%和12.4%。综上,矿源黄腐酸钾和鱼蛋白都有利于促进番茄的生长发育和品质改善,且以处理T1添加10%矿源黄腐酸钾+40%鱼蛋白表现最好。

The effects of different treatments on agronomic characters,yield and quality of tomato were studied.Five treatments were set based on applying a water-soluble maoronutrient fertilizer.There were without adding mineral based potassium fulvate and fish protein(CK control),mineral based potassium fulvate 10%+fish protein 40%(T1),mineral based potassium fulvate 10%+fish protein 20%(T2),mineral based potassium fulvate 10%+fish protein 10%(T3)and mineral based potassium fulvate 10%(T4).The results showed that compared with CK,stem diameter of treatment T1 to T4 increased significantly by 17.07%,15.15%,11.53%and 5.03%,respectively.There was no significant difference in tomato SPAD value among all treatments.T1~T4 increased single fruit weight significantly by 24.62%,18.63%,14.62%and 8.53%,respectively.The yield of T1 to T4 increased significantly by 8.2%,6.6%,5.6%and 3.8%,respectively.The soluble solids were consistent with total sugar content,but opposite to total acidity content.The sugar-acid ratio among all treatments was significant different with CK,optimal for T1.The Vc content of T1 to T4 increased significantly by 22.5%,18.1%,14.8%and 12.4%,respectively.In conclusion,both mineral based potassium fulvate and fish protein could promote the growth and quality improvement of tomato,and the optimal treatment was T1.
