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.
The differences of soil organic matter, total nitrogen, available nitrogen, available phosphorus, available potassium and pH in rhizosphere of cultivated hops with different growing years were analyzed. The results showed that compared with 5-year-old, the pH values of rhizosphere soil of 8, 18, 20 and 22 year-old hops decreased by 2.00%, 4.00%, 5.11% and 6.00% respectively, while available phosphorus increased by 14.87% and 45.53% 177.83% and 228.33%, respectively. Available potassium increased by 4.56%, 29.34%, 149.20% and 157.86% respectively. Organic matter in rhizosphere soils increased by 32.11%, 67.34% and 84.50% 56.34%, 76.06% and 83.10% respectively. Available nitrogen increased by 52.16%, 84.23% and 152.20% respectively. With the growth of hops growing, the rhizosphere soil nutrient enrichment.
