本试验于1964—1967年进行。1.茶园追施不同品种氮肥对增加茶叶产量均有一定效果,祁门茶区以氯化铵最好,硫铵、尿素次之,硝铵最差。宣郎广红土丘陵区以硫铵最好,氯化铵、硝铵次之,尿素较差。2.因气候条件影响,施肥效果各季差异较大,春茶施尿素、硫铵较好,夏茶施氯化铵、硫铵较好,尿素在多雨季节效果好,而硝铵则在多雨和旱季均较差。
This experiment was carried out in 1964-1967. 1. Tea plantation topdressing different varieties of nitrogen fertilizer to increase the yield of tea have a certain effect, Qimen tea area to the best ammonium chloride, ammonium sulfate, followed by urea, ammonium nitrate is the worst. Xuan Lang Canton hilly area to the best ammonium sulfate, ammonium chloride, followed by ammonium nitrate, urea is poor. Due to the climatic conditions, the effect of fertilization varied greatly in different seasons. The application of urea in spring and ammonium sulphate was better in summer tea, while ammonium chloride and ammonium sulphate in summer tea were better. The effect of urea in rainy season was good, And the dry season are poor.
