Evaluation of soil nutrient status of tea garden in southern Henan Province
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 8
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."
