摘要
【目的】为明确园林绿化过程中,施用生化黄腐酸钾对多种树木移栽成活率和生长的促进作用。【方法】设置腐熟有机肥+生化黄腐酸钾水溶肥、腐熟有机肥+复合肥2个试验处理,测定土壤处理前后理化性质的变化及4种绿化树木移栽一年内的成活率、株高和地径,研究添加生化黄腐酸钾对栽培植株的影响。【结果】种植移栽植株的土壤经腐熟有机肥+生化黄腐酸钾水溶肥、腐熟有机肥+复合肥处理后,土壤有机质(Soil organic matter)、全氮(Total nitrogen)、碱解氮(Alkali-hydrolyzable nitrogen)、土壤速效确(Soil available phosphorus)、土壤速效钾(Soil available Potassium)、pH值均有明显的升高,土壤容重(Soil bulk density)明显下降;种植土壤经腐熟有机肥+生化黄腐酸钾水溶肥、腐熟有机肥+复合肥处理后,4种不同栽培植株的成活率、株高和地径均有显著的改善(P<0.05)o【结论】滋用生化黄腐酸钾能有效提高土壤肥力,提高植物对氮、磷、钾的利用率,改善植株生长量,对园林绿化树木移栽后有较好的促进作用。
[Objective]The study aimed to clarify the application of biochemical fulvic acid potassium product on the survival rate and growth of various trees transplanted in the process of landscaping.[Method]In this study,two experimental treatments(i.e.decomposed organic fertilizer+biochemical fulvic acid potassium water soluble fertilizer,decomposed organic fertilizer+compound fertilizer)were set up to determine the changes of physical and chemical properties before and after soil treatment,and the survival rate,plant height and ground diameter of four different cultivated plants in one year,and the effects of adding biochemical fulvic acid potassium on cultivated plants were investigated.[Result]The results showed that the soil organic matter,total nitrogen,alkali-hydrolyzable nitrogen,soil available phosphorus,soil available potassium,the pH value in the soil treated with decomposed organic fertilizer+biochemical fulvic acid potassium soluble fertilizer,decomposed organic fertilizer+compound fertilizer increased significantly,and the soil bulk density decreased obviously.The survival rate,plant height and ground diameter of the four different cultivated plants were significantly improved after the treatment with decomposed organic fertilizer+biochemical fulvic acid potassium w砒er soluble fertilizer,decomposed organic fertilizer+compound fertilizer(P<0.05).[Conclusion]The application of biochemical fulvic acid potassium on cultivated plants and effectively improve soil fertility,increase the utilization of nitrogen,phosphorus and potassium,improve the growth of plants,and promote the landscaping plants.
