| 摘 要： | 为明确豫南茶园土壤营养状况,指导豫南茶园科学施肥,以期为茶叶的优质高产提供依据,通过对豫南茶区9个主要产茶县(区)45个重点乡镇的茶园土壤进行多样本取样、分析测定,结果表明:豫南茶园土壤p H偏酸化;有机质含量低,仅有16.73%的茶园符合优质高产茶园要求;全氮供应能力较好,有效氮含量较丰富,分别有85.66%、87.25%茶园土壤达到优质高产茶园要求;61.35%的茶园土壤有效磷含量很低;大部分茶园土壤速效钾亏缺严重;中量元素有效态Ca含量丰富,Mg、S含量偏低,分别有50.63%、68.52%的茶园低于临界值;微量元素有效Fe、Mn供应充足,Zn含量水平中等,不同茶园之间差异很大,Cu、B缺乏严重。为此,豫南茶园应在施足有机肥的基础上,增施磷、钾肥,同时注意补充S、Mg、Cu和B肥,部分茶园也应补充Zn肥。

| Abstract: | For making soil nutrient status of tea garden in south Henan clear and guiding scientific fertilization
of tea garden in the hope of providing the basis for high-quality and high-yield production of tea. The study of tea
garden in south Henan were analyzed by multi-sample which were the focus of 45 villages and towns of 9 main tea
producing counties (districts) in south Henan. The results showed that the tea garden soil pH were partial acidification
and the organic matter content were low, only 16.73% of tea garden in south Henan accorded with the requirement of
high-quality and high-yield production of tea garden. The supply ability of the total N was better, and the effective N
content was relatively abundant. There were 85.66% and 87.25% of tea garden soil to meet the requirements of highquality
and high-yield production of tea garden; The effective P content of 61.35% of tea garden soil were very low;
Most of the tea garden soil were seriously deficient in available K. In the middle elements, the available Ca contents
were abundant, and the Mg and S contents were low, 50.63% and 68.52% of tea garden were lower than the critical
value. In the trace element, the available Fe and Mn were in abundant supply, Zn content were medium, there was a
great difference among different tea garden, and the lack of Cu and B were serious. Therefore, the tea garden in south
Henan should increase P, K fertilizer on the basis of applying organic fertilizer, and pay attention to supplementing S,
Mg, Cu and B fertilizer. Some tea garden should also supplement Zn fertilizer. |
