为了探讨枸杞栽植后土壤理化性质的演变规律,以定植1a和定植6a的枸杞地为研究对象,对枸杞样地0~20cm和20~40cm的土层的土壤理化性质进行对比分析,结果表明:人工开垦会导致土壤肥力下降,但栽植枸杞后,土壤理化性质有所改善,不同土层深度养分含量的变化非常一致,土壤有机质、氮素、磷素等指标均随枸杞定植时间延长而逐渐增大,随着土壤深度的增加而降低。对土壤理化性质改良效果最好的是定植6a,定植1a改良效果次之。枸杞栽植后,降低了土壤pH值,土壤有机质、有机碳、N和K有所提高。
In order to investigate the evolution of soil physico-chemical properties after the planting of Lycium barbarum L., the soil physicochemical properties of 0-20 cm and 20-40 cm soil layers of Lycium barbarum were compared and analyzed. The results showed that: Artificial reclamation led to decreased soil fertility, but after the planting of Chinese wolfberry, soil physical and chemical properties have improved, the depth of different soil nutrient content changes are very consistent, soil organic matter, nitrogen, phosphorus and other indicators are gradually increased with the wolfberry colonization time Large, with the depth of the soil decreases. Soil physical and chemical properties of the best improvement is the colonization 6a, colonization 1a second to improve the results. After the planting of Chinese wolfberry, the pH value of soil was decreased, and the contents of soil organic matter, organic carbon, N and K were increased.
