Application of Biochar for Tea Plantation

Tea Research Institute,Fujian Academy of Agricultural Sciences

摘要

摘要: 分别在武夷山市、安溪县、永春县和华安县进行生物黑炭茶园应用技术示范研究, 结果表明:茶园土壤施用生物黑炭后, 土壤pH值提高0.12⁰.20个单位, 酸化茶园土壤得到明显改良;土壤有机碳含量提高4.14%²9.37%, 碳截留效果显著;土壤全氮提高3.34%²3.98%, 有效氮含量下降3.40%⁹.83%, 有效磷含量提高1.61⁹.69mg·kg-1, 速效钾含量提高9.13%¹33.79%;茶园年鲜叶产量提高1.71%⁸.28%, 经济效益初步体现。综合示范结果, 生物黑炭茶园施用可以作为一项改善茶园土壤性状、提高茶叶产量的栽培技术, 建议进一步扩大示范面积。

Abstract: A series of experiments applying biochar was carried out on tea plantations in the city of Wuyi Mountain, Anxi County, Yongchun County and Hua'an County.The following results were obtained: (a) the soil pH increased 0.12-0.20 over the control, significantly ameliorating the acidity; (b) the soil organic carbon increased4.14%-29.37%, significantly increasing the carbon sequestration of the soil; (c) the total nitrogen increased3.34%-23.98%, hydrolyzable nitrogen decreased 3.40%-9.83%, the available phosphorus increased 1.61-9.69mg·kg-1, and the available potassium increased 9.13%-133.79%in the soils, as compared to the control;and, (d) the fresh leaf yield increased 1.71%-8.28%, significantly improving the economic return.Thus, it was concluded that the application of biochar could be used to improve soil properties and tea yield for a tea plantation.An extended testing on additional planting areas was recommended for further confirmation and demonstration of the effects.
