1971—1974年共五年的试验结果表明,茶树与许多嫌氯作物一样,对化肥中氯离子反应十分敏感,如施用量和施用方法掌握不当,易造成肥害,尤其是幼令茶园及干旱的三、四茶期间最为明显。茶树的氯化氨肥害与茶树年令,品种、土壤湿度和气温都有密切关系。三年生幼令茶园亩施15～20斤氯化氨时就出现为害,成令采摘茶园亩施30斤氯化氨以上才出现局
The results of a total of five years between 1971 and 1974 show that tea trees, like many suspected chlorine crops, are very sensitive to the chloride ion in chemical fertilizers. Inappropriate application and application of tea tree can easily lead to fertilizer damage, especially young tea plantations and drought The three or four during the most obvious tea. Tea tree ammonia chloride fertilizer damage and Tea Year, varieties, soil moisture and temperature are closely related. Three-year-old young tea plantations Mushu 15 to 20 kg of ammonium chloride appeared harmful when Chengmushu tea plantation acupuncture 30 kg of ammonia chloride above only appeared Bureau
