主要结果;(一)氮磷钾化肥与茶叶产量的关系:①氮肥的增产作用最显著。与不施肥比较,单施氮肥的处理,前三年平均增产1.99倍,后七年平均增产5.46倍,十年平均增产4.75倍;随着时间的延长,凡是施有氮肥的处理,增产幅度更明显。单施磷肥和钾肥,平均各有增产;③氮肥配施磷、钾肥比单施氮肥有更好的作用,与不施把比较,十年平均,氮磷配合
The main results; (A) the relationship between NPK fertilizer and tea yield: ① the most significant increase in nitrogen fertilizer. Compared with no fertilization, the application of nitrogen fertilizer alone increased the average yield of 1.99 times in the first three years, 5.46 times in the latter seven years and 4.75 times in the past ten years; with the extension of time, obvious. Phosphorus and potassium fertilizer alone, with an average increase; ③ nitrogen fertilizer with phosphorus and potassium than single nitrogen fertilizer have a better role, and do not apply to compare the ten-year average, with nitrogen and phosphorus
