摘  要:
对比分析了不同生长年限栽培啤酒花根际区土壤有机质、全氮、速效氮、速效磷、速效钾及pH含量差异。结果表明,与5年生的相比,8、18、20、22年生啤酒花根际土壤pH值分别降低了2.00%、4.00%、5.11%和6.00%;速效磷分别增加了14.87%、45.53%、177.83%和228.33%;速效钾分别增加了4.56%、29.34%、149.20%和157.86%18、20和22年生啤酒花根际土壤有机质分别增加了32.11%、67.34%和84.50%;全氮分别增加了56.34%、76.06%和83.10%,速效氮分别增加52.16%、84.23%和152.20%。随啤酒花生长年限的增加,其根际区土壤出现养分富集.

摘  要:
Soil organic matter,total N,ava ilable N,available P,available K and pH were determined in therhizosphere of Hops planted in different years.The results showed that the pH values in rhizosphere of hops planted in 8,18,20 and 22 years decreased 2.00%,2.00%,5.11%and 6.00%compared with that planted in 5 years,and theavailable P inereased 14.87%,45.53%,1 77.83%and 228.33%,the available K raised 4.56%,29.34%,1 49.20%and1 57.86%as well.The soil organic matter enhaneed 32.11%,67.34% and 84.50%in the treatments with 1 8,20,22planted years,the total N inereased 56.34%,76.06%and 83.10% and the available N raised 52.1 6%,84.23% and1 52.20%.
