1972年,我们在茶树施用氯化铵后对茶叶(绿茶)品质的影响进行研究的同时,根据生产上存在的种种迹象,研究了氯化铵对茶树短穗扦插成活的影响,现简介如下: 取扦插繁殖4年生的福鼎大白茶作试验母株。茶园土壤为发育于第四纪红土层的红壤,土层1米以上,土壤酸性,pH_水4.65～5.00,代换性酸为每100克土4.16～4.63毫当量,代换性铝及代换性氢的含量分别为每100克土4.00～4.45及0.16～0.18毫当量左右(80厘米以上的土层)。该茶园1971～1972年冬季间作蔬菜,土壤中各种营养料颇为丰富。地形属缓坡下方。
In 1972, we studied the effects of ammonium chloride on tea (green tea) quality after tea tree application, and studied the effects of ammonium chloride on the short-spike cuttings of tea plant according to various signs of production. The brief introduction is as follows: Four-year-old cuttage breeding Fuding Da Bai tea was taken as the test strain. The tea garden soil is a red soil developed in the Quaternary lateritic soil layer, the soil layer is more than 1 meter, the soil acidity, the pH_water is 4.65 ~ 5.00, the substitutional acid is 4.16 ~ 4.63 milliequivalents per 100 grams of soil, The content of exchangeable hydrogen is respectively from 4.00 to 4.45 and from 0.16 to 0.18 milliequivalents per 100 grams of soil (soil above 80 cm). The tea garden for the winter of 1971 ~ 1972 for the vegetables, various nutrients in the soil is quite rich. Terrain is a gentle slope below.
