摘要:

为了解江西省上饶市广丰区马家柚园土壤肥力的整体状况,以广丰区4个乡镇10个马家柚园土壤(0~30 cm)为研究对象,测定了土壤的pH值、有机质含量、速效氮含量、速效磷含量、速效钾含量和阳离子交换量,采用单因子评价、综合评价法对土壤肥力进行了评价。结果表明:马家柚主产区土壤pH均值为5.46;阳离子交换量、有机质含量中等,均值分别为11.66 cmol·kg-1、22.64 g·kg-1;速效磷、速效钾含量丰富,均值分别为52.60、190.38 mg·kg-1;速效氮缺乏,均值为7.80 mg·kg-1。10个柚园土壤肥力综合指数(IFI)均值为0.53,肥力Ⅱ和Ⅲ级占70%,30%的柚园肥力较低。10个马家柚园普遍缺乏氮素养分,应注意多施氮肥,适当减少磷、钾肥用量,多施有机肥以提高土壤保肥供肥能力,改善土壤物理性状。

Abstract:

Soil samples (0-30 cm) from ten Majia pomelo orchards were collected in four towns of Guangfeng District, Shangrao City, Jiangxi Province, in order to find out the soil fertility status of Majia pomelo orchards. The chemical properties of the soil pH value, organic matter, available nitrogen, available phosphorus, available potassium contents, and cation exchange capacity were measured, and soil fertility characteristics were evaluated by single factor evaluation and comprehensive evaluation. The results showed that average soil pH value in the main production area of Majia pomelo was 5.46, the average cation exchange capacity and organic matter content was moderate, which was 11.66 cmol·kg-1 and 22.64 g·kg-1, respectively. The average contents of available phosphorus and available potassium were 52.60 and 190.38 mg·kg-1, respectively, indicating abundant content. The average content of available nitrogen was 7.80 mg·kg-1, indicating a relative deficiency. The average comprehensive index (IFI) of soil fertility in 10 pomelo orchards was 0.53, 70% of sites classified as grade Ⅱ and Ⅲ, and 30% of pomelo orchards with lower fertility. Ten Majia pomelo orchards are generally lack of nitrogen nutrients, more nitrogen fertilizer should be applied. It is necessary to reduce the amount of phosphorus and potassium fertilizers appropriately, and application of more organic fertilizer is helpful to improve soil fertility and promote soil physical properties.
