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0.12~0.20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1.61~9.69mg·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。

摘  要：
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.
