目前在茶叶生产用肥上,长期存在重氮,轻磷、钾现象,造成茶园土壤营养元素比例严重失调。而在高产茶园中,重施氮肥换来的增产单值也明显下降,且品质也明显下降。因而寻找有利于提高茶叶产量和品质的复合营养元素肥,已越来越被人们重视。本试验以含 At present, there is a long-standing phenomenon of diazo, phosphate and potassium in the fertilizer used for tea production, resulting in a serious imbalance in the proportion of nutrient elements in the tea plantation soils. In the high-yield tea plantation, the single value of heavy application of nitrogen fertilizer in return also significantly decreased, and the quality also dropped significantly. Therefore, looking for conducive to improve the yield and quality of tea compound nutrient fertilizer has been more and more people’s attention. This test to contain
