摘　　要：为进一步探索酸化土壤改良技术的最佳效果及方法,根据茶树良种场茶山分场茶园土壤酸性状况,制定酸化土壤改良对比试验方案,连续施用2年,并对试验茶园的土壤pH以及茶叶产量进行测定。结果表明,不同调酸措施均能够提高茶园土壤pH,其中,处理A、B的pH增加最显著,与处理前相比,分别增加了2.13和2.22个pH单位,且不同处理间的产量也存在一定差异;与CK相比,处理E增产率最高,处理1年后的增产率为9.27%,处理2年后的增产率为11.44%。综上可知,双飞粉、橡胶籽油枯、钙镁磷、尿素、阿姆斯微生物菌肥均具有调节土壤酸化的作用,双飞粉会使土壤pH在短时间内快速上升,橡胶籽油枯、钙镁磷、尿素配合施用在提高土壤pH的同时,也能在一定程度上提高茶叶产量。To further explore the best method for improving acidified soil,this study developed a comparative trial program for improving acidified soil based on the acidic conditions of tea plantation soil in the Tea Mountain Branch of the Tea Tree Breeding Farm,which was applied continuously for two years,and the soil pH value and tea yield of the test tea plantation were measured.The test results revealed that different acid-regulating measures improved the soil pH value of tea plantations,among which the pH values of treatment A and treatment B increased the most significantly.Compared with that before treatment,the pH value increased by 2.13 and 2.22 pH units,respectively,and there were also some differences in yield between different treatments.Compared with CK,treatment E had the highest yield increase rate,the yield increase rate at treatment 1 year was 9.27%,and the yield increase rate at treatment 2 years.In summary,double fly powder,rubber seed oil cake,calcium and magnesium phosphorus,urea,and Ams microbial fertilizer play roles in regulating soil acidification application,and dolomite powder causes the soil pH value to increase rapidly for a short period of time.Rubber seed oil wilt,calcium and magnesium phosphorus,urea,and the application of these fertilizers improve soil pH at the same time,but also,to a certain degree,increase the yield of tea leaves.
