一九四九年前,西格鲁吉亚茶园仅施入氮肥和磷肥,而钾肥则没有施入,致使许多茶园,特别是五十年生的查克瓦老茶园土壤中钾的天然蓄量消耗殆尽,因而无机营养不能满足需要。造成茶树,尤其是老茶园的茶树严重缺钾;使得甚至在进行良好管理和氮磷营养充分的茶园,茶叶产量显剧下降。缺钾所引起的生理失调,不仅表现在产量的下降上,而且茶叶在外表
Before 1949, only fertilizers and phosphate fertilizers were applied to the tea plantations in West Georgia, while potash was not applied. As a result, the natural reserves of potassium in many tea farms, especially the 50-year-old Chakwa tea plantation soils, Thus inorganic nutrition can not meet the needs. Resulting in a serious shortage of potassium in the tea tree, especially in the old tea plantation; so that even in the well-managed tea plantations where nitrogen and phosphorus are well-served, the output of tea leaves has drastically decreased. Potassium deficiency caused by physiological disorders, not only reflected in the decline in production, and tea in the appearance
