遵义市樱桃园不同土层肥力质量评价

Evaluation on Soil Fertility Quality in Different Soil Layers of Cherry Orchards in Zunyi City

摘要: 为了解遵义市樱桃园土壤肥力质量的垂直变化规律，分别对健康樱桃园与病害樱桃园（患流胶病）的不同土层即0~10、10~20、20~30 cm的土壤进行分析和评价。结果表明：（1）随着土层的加深，健康和病害樱桃园土壤有机质、全氮、全磷、有效氮、有效磷、有效钾含量均逐渐降低。健康樱桃园土壤pH值随着土层的加深而逐渐降低，病害园则相反。（2）健康和病害樱桃园0~10、10~20、20~30 cm土层的土壤肥力质量均分别为Ⅱ级、Ⅲ级、Ⅳ级。

Abstract: In order to understand the vertical change law of soil fertility quality of cherry orchards in Zunyi City, the soil layers of 0-10 cm, 10-20 cm and 20-30 cm in healthy and diseased (suffering from gummosis) cherry orchards were analyzed and evaluated. The results showed that:(1) With the deepening of soil layer, the contents of soil organic matter, total nitrogen, total phosphorus, available nitrogen, available phosphorus and available potassium decreased gradually in both healthy and diseased cherry orchards. The pH value of soil in the healthy cherry orchards decreased gradually with the deepening of soil layer, while the soil pH value in the diseased cherry orchards changed on the contrary. (2) The soil fertility quality of 0-10 cm, 10-20 cm and 20-30 cm soil layers in the healthy and diseased cherry orchards were respectively grade Ⅱ, grade Ⅲ and grade Ⅳ.
