- 摘要:
- 为全面了解和掌握延边地区苹果梨园土壤养分总体状况,实现苹果梨园科学合理施肥,对延边地区苹果梨主要产区果园进行土壤养分调查和分析。结果表明:延边地区苹果梨园土壤pH为5.03±0.10,全量养分中有机质、全氮、全磷、全钾含量平均值分别为14.71±0.87 g.kg-1、0.64±0.02 g.kg-1和0.35±0.03 g.kg-1、32.48±1.15 g.kg-1,速效养分中碱解氮、速效磷、速效钾分别为91.94±4.52 mg.kg-1、35.25±2.15 mg.kg-1和129.82±7.43 mg.kg-1,且苹果梨园土壤全氮、碱解氮、速效磷、速效钾与有机质分别呈显著或极显著正相关。从养分总体水平来看,养分呈下降趋势,因此,延边地区苹果梨园在土壤管理方面要注重施肥,特别是要注重有机肥的施入。
- Abstract:
- In order to fully understand and grasp the overall situation of soil nutrient of apple-pear orchand in Yanbian area,realize scientific and reasonable fertilization in apple-pear orchards,the investigation and analysis on soil nutrient of apple-pear orchards in Yanbian area were conducted.The results showed that the average pH of Yanbian’s apple-pear orchards was 5.03±0.10,the soil organic matter,the total nitrogen,the total phosphorus,the total kalium content were 14.71±0.87 g.kg-1,0.64±0.02 g.kg-1,0.35±0.03 g.kg-1,32.48±1.15 g.kg-1,respectively.The average value of the content of hydrolysable nitrogen,the available phosphorus,the available kalium were 91.94±4.52 mg.kg-1,35.25±2.15 mg.kg-1,129.82±7.43 mg.kg-1,respectively.The correlation analysis on the soil nutrient of apple-pear orchards indicated that the total nitrogen,the hydrolysable nitrogen,the available phosphorus and the available kalium showed the significant or very significant positive correlation with the soil organic matter.From the view of the overall level of nutrient,the overall level of nutrients decreased.So,it should be paid attention to fertilizer in the orchard management of apple-pear in Yanbian area,especially to the application of organic fertilizer.
