东阳市‘木禾群体种’生长茶园土壤养分状况分析

Analysis of soil nutrient status in tea garden of ‘Mu-He population variety’ in Dongyang City

东阳市茶园种植品种主要是‘木禾群体种’、‘龙井43’、‘浙农117’、‘白叶一号’等,其中‘木禾群体种’占比65%以上,而且茶园土壤是红黄壤为主。对不同地域环境茶园土壤抽样调查和理化分析,同一土壤类型中,pH值、有机质含量、全氮含量、有效磷、速效钾、氟化物、微量元素与海拔高度无相关关系;不同土壤类型,各类土壤肥力指标无明显规律,微量元素含量无明显差异。建议土壤酸化茶园适时施有机肥和配方肥,改善土壤现状。

The tea plantation varieties in Dongyang City are mainly‘Mu-He population variety’,‘Longjing 43’,‘zhenong 117’,‘Baiye 1’,and etc.,of‘Mu-He population variety’accounts for more than 65%of total,and the tea garden soil is mainly red and yellow soil.According to the sampling survey and physicochemical analysis of tea garden soils under different environments,there was no correlation between pH value,organic matter content,total nitrogen content,available phosphorus,available potassium,fluoride and trace elements and altitude in the same soil type.There was no obvious regularity in various soil fertility indexes and no significant difference in trace element content among different soil types.It is suggested that soil acidification in tea garden should apply organic fertilizer and formula fertilizer in time to improve the current situation of soil.
