摘要
【目的】为探明福鼎市主要产茶乡镇茶园土壤养分状况,更好指导福鼎茶园科学施肥。【方法】本研究对福鼎市5个乡镇的15个行政村进行实地调查和土壤取样,检测福鼎市茶园土壤pH值、有机质、全氮、全磷、全钾、碱解氮、速效磷、速效钾等养分指标,并对肥力等级进行评价。【结果】福鼎市大部分茶园土壤pH介于4.05~4.29,适合茶树生长;有机质含量为11.22~79.05 g·kg^(-1),除白琳镇和管阳镇部分茶园外,肥力等级均达Ⅰ级标准;土壤全氮含量处于中上水平,分别为0.68~2.43 g·kg^(-1),但碱解氮含量较低;全磷含量为0.08~1.03 g·kg^(-1),除点头镇茶园外肥力等级均达Ⅰ级标准;速效磷含量差异较大,为4.44~91.43 mg·kg^(-1),其中太姥山镇40.70%茶园土壤肥力等级为Ⅲ级标准,速效磷供应不足;90%以上的茶园土壤全钾含量超过10 g·kg^(-1),肥力等级达到Ⅰ级标准,其中磻溪镇茶园土壤速效钾含量最高,为221.95 mg·kg^(-1)。【结论】福鼎市主要产茶乡镇茶园土壤整体肥力水平较优,但部分乡镇取样点碱解氮与速效磷不足,可通过改进施肥方式或肥料种类进一步提高。
【Objective】Fertility of plantation soil at the tea-producing townships in Fuding City was analyzed and evaluated to better the fertilization practice in the area.【Method】A field survey and soil sampling were conducted at 15 villages in 5 townships of Fuding City.Contents of organic matter,and total alkaline hydrolysable nitrogen,and total available phosphorus,and total available potassium,as well as pH of the soils were analyzed.The fertility level of all plantations was aslo evaluated.【Result】The pH of the soil sampled at various plantations was lowest at 4.05~4.29 and largely adequate for the growth of tea plants.The organic matter contents ranging 11.22~79.05 g·kg^(-1) met the Grade I standard for all sites except some at Bailin and Guanyang.The total nitrogen of 0.68~2.43 g·kg^(-1) was considered at an upper-medium level in all plantations,while the content of alkaline hydrolysable nitrogen at low level.The content of total phosphorus at various plantations ranged 0.08~1.03 g·kg^(-1),which met Grade Ⅰ standard for all sites except some at Diantou township.The available phosphorus at the sites varied significantly between 4.44 mg·kg^(-1) and 91.43 mg·kg^(-1).It was at the Grade Ⅲ standard,at 40.70% Taimushan tea plantations,manifesting as insufficient supply of available phosphorus.More than 90%tea garden soils met the Grade I standard with the total content potassium exceeding 10 g·kg^(-1).The greatest available potassium of 221.95 mg·kg^(-1) were found at Panxi.【Conclusion】The overall fertility levels in the soils at the surveyed Fuding tea plantations was adequate.But a shortage of alkaline hydrolysable nitrogen and available potassium at certain localities needed to be adequately supplemented with proper fertilization.
