- 摘要:
- 以沈阳地区具有代表性的8个县、区内处于盛果期的果园为调查对象,调查果园的管理状况并用土钻采集土壤样本,研究分析了“寒富”苹果栽培新区的土壤管理及0~20、20~40、40~60 cm土层土壤的pH值、有机质以及速效态的N、P、K等养分现状。结果表明:调查的苹果园大多已由传统的土壤清耕管理模式转为自然生草模式,果园平均草种15种;“寒富”苹果园土壤pH值处于6.01~7.69,部分果园土壤为弱酸性;土壤养分分布极不平衡且土壤养分表聚化明显,其中有机质含量为(1.27±0.28)%,速效氮、磷、钾含量分别为(54.05±12.43)、(24.69±5.98)、(108.34±22.87) mg/kg。因此,针对以上现状应及时改善沈阳地区“寒富”苹果园的管理现状,适当调整施肥策略以促进“寒富”苹果产业的健康可持续发展。
- Abstract:
- The 8 typical ‘Hanfu’ apple orchards in full fruit period in Shenyang area were chosen proceed to investigate the managing status and collected soil samples by questionnaire and soil core respectively.Then the soil pH value,organic matter and available nutrients were analyzed in different layers included 0-20 cm,20-40 cm,40-60 cm.The results showed that the majority of apple orchards have been changed the management from conventional tillage to sod cultivation,the average grass species were 15.The pH values of apple orchards were between 6.01 and 7.69,the soil pH values of part of the orchards were weak acid.Furthermore,the distribution of nutrients was out of balance and concentrated on the topsoil was obvious.The average contents of soil organic matter,available N,available P and available K were (1.27±0.28)%,(54.05±12.43) mg/kg,(24.69±5.98) mg/kg and (108.34±22.87) mg/kg respectively.In order to promote industry development of ‘Hanfu’ apple in healthily and sustainable,the current situation about managements should be improved in hurry,and adjust tactics of fertilizing in the same time.
