南丰蜜桔生产环境状况调查研究

从对南丰蜜桔生产的土壤条件、果品品质、叶片养分和管理水平调查入手,系统分析了南丰蜜桔的生产状况,结果表明:南丰蜜桔生产施肥还不合理,管理还不到位;从叶片诊断判断,南丰蜜桔N素养分适宜,P、K养分偏低或缺乏;从土壤条件判断,南丰蜜桔应注意N、P、K的配合和土壤酸度的调节与Ca、Mg、Zn养分的投入。

Investigation on Production Environments of Nanfeng Orange

Production environmental status of Nanfeng orange was systematically analyzed through investigating soil conditions, fruit quality, nutritional status of leaf and level of production management, the results showed that applying fertilizer to Nanfeng orange was not reasonable, production management was poor. The diagnosis of leaves nutrients implied that the nitrogen nutrient was appropriate, but the phosphorus and potassium nutrients were deficient. The analysis of soil conditions suggested that the production of Nanfeng orange should attach great importance to the rational distribution of nitrogen, phosphorus and potassium nutrients, the adjustment of soil acidity and the input of Ca, Mg and Zn nutrients.
