    摘要:

    为了明确浉河区茶园土壤养分状况,对浉河区山地与丘陵茶园分别进行了 26和 84个土壤取样、分析测定,为茶园土壤培肥管理提供科学依据。结果表明:浉河区茶园土壤 pH偏酸化,有机质含量偏低,山地茶园平均值(22.0 g/kg)比丘陵茶园(14.4 g/kg)高 52.78%;在全氮、速效钾整体含量处于中等偏低水平,大部分茶园有效磷匮缺严重情况下,山地茶园土壤营养状况比丘陵茶园好,其全氮、有效磷含量整体水平高于丘陵茶园,有效钾略低于丘陵茶园,但差异性不明显;中微量元素有效态 Ca、Mg、S、Mn、Zn含量丰富,但山地茶园含量比丘陵茶园更能满足茶树生长发育需要,Fe异常丰富,Cu、B严重缺乏。为此,浉河区茶园应在施足有机肥的基础上,增施磷肥,部分茶园要加大氮、钾肥施用量,同时注意补充 Cu和 B肥。

    Abstract:

    In order to clarify the soil nutrient status of tea garden in Shihe area and provide scientific basis for soil fertilizermanagement in teagarden,26 and 84 soil samples were collected and analyzed for mountain tea garden and hilly tea gardenin Shihe arearespectively.Results showed that soil pH of tea garden in Shihe area was partial acidification and organic mattercontent waslow,and the average organic matter content in mountain tea plantations was 22.0g/kg,being 52.78% higherthan that of hilly teagarden,which was 14.4g/kg.Soil total nitrogen content and available potassium were at a moderateto inferior level and available phosphorus was serious low in most tea gardens.The soil nutrition contents of mountain teagarden were better than those of hilly teagarden,the total nitrogen and available phosphorus were higher than those in hillyteagarden,while available potassium was slightly lower but the difference was notobvious.Middle elements contentsincluding available Ca,Mg,S,Mn,Zn were rich,and their contents in mountain tea garden were more satisfied withthe requirement of tea growth than hilly teagarden.Fe was enormouslyrich,while the deficiency of Cu and B wasserious.Therefore,the application of phosphorus should be increased on the basis of applying sufficient organic fertilizer in Shihearea;Nitrogenfertilizer,potassium fertilizer should also be added to some teagarden,and Cu and B fertilizers should bepayed attention to supplement at the sametime.
