【摘要】：为研究海洋类土壤改良剂的作用效果,采用田间对比试验,分析了虾肽肥、鱼蛋白肥、海藻肥3种海洋类土壤改良剂对土壤理化性状及烤烟生长和产量的影响。结果表明:施用虾肽肥可于移栽后55 d有效提高土壤碱解氮、速效钾含量,但对烤烟生长和产量无明显影响;施用鱼蛋白肥可显著提升55 d时土壤碱解氮、有效磷、速效钾水平,显著提高烟株根系活力、中部叶最大叶长、干物质积累量,其烤后烟叶产量、产值分别较对照提高27.79%、29.84%;施用海藻肥可明显降低75 d时土壤容重,于55 d显著提升土壤碱解氮、有效磷、速效钾水平,显著提高中部叶最大叶长、干物质积累量,其烤后烟叶产量、产值分别较对照提高11.75%、20.05%。综上,施用鱼蛋白肥、海藻肥可在一定程度上改良土壤,有效促进烤烟生长,显著提高烟叶产量。
[Abstract]:In order to study the effect of marine soil improver, shrimp peptide fertilizer and fish protein fertilizer were analyzed by field contrast experiment. Effects of three marine soil modifiers on soil physical and chemical properties, growth and yield of flue-cured tobacco. The results showed that the application of shrimp peptide fertilizer could effectively increase the content of soil alkali-hydrolyzed nitrogen and available potassium in 55 days after transplanting. But there was no significant effect on the growth and yield of flue-cured tobacco, the application of fish protein fertilizer could significantly increase the soil alkali-hydrolyzed nitrogen, available phosphorus, available potassium, root activity, maximum leaf length and dry matter accumulation at 55 days. The yield and output value of tobacco leaf were increased by 27.79 ~ 29.84, and the soil bulk density was significantly decreased by applying seaweed fertilizer for 75 days, and the soil alkali-hydrolyzed nitrogen, available phosphorus, available potassium and the maximum leaf length of middle leaf were significantly increased at 55 days after application of seaweed fertilizer. The dry matter accumulation, the yield and output value of cured tobacco were increased by 11.75% and 20.05, respectively. In summary, applying fish protein fertilizer and seaweed fertilizer could improve the soil to some extent, effectively promote the growth of flue-cured tobacco, and significantly increase the yield of tobacco leaf.
