通过1962～1965年条栽茶园氮肥用量试验表明,增施氮肥可以使茶叶产量获得大幅度提高,氮肥用量与茶叶产量呈曲线相关。在基肥基础上每亩增施纯氮60斤范围内茶叶产量不断增加,超过60斤时茶叶产量增长缓慢,而氮肥用量与经济效益呈直线相关。随着氮肥用量的提高,茶叶中氮素的回收率有不断下降的趋势。根据本试验结果,在普通条栽成令茶园上,
Through 1962 ~ 1965 years planted tea plantation nitrogen fertilizer test showed that the application of nitrogen fertilizer can make tea yield increased significantly, the amount of nitrogen fertilizer and yield of tea showed a curve related. On the basis of basal fertilizer per acre added pure nitrogen within 60 kg range of tea production continues to increase, more than 60 kg of tea production increased slowly, while the amount of nitrogen fertilizer and the linear correlation between economic benefits. With the increase of the amount of nitrogen fertilizer, the recovery rate of nitrogen in tea has been declining. According to the test results, in order to make tea plantations,
