摘要
对茶树施用3种不同配比的Kemira肥料,结果表明,经过不同氮、磷、钾配比的Kemira肥料处理,土壤中有效磷,有效钾的水平和茶叶中氮、磷、钾各养分元素的含量均比仅施用氮肥的对照高,而土壤有效氮的含量低于对照,施用Kemira肥的各处理均改善了春茶某些生理生化指标,提高了茶叶的品质,同时增加了茶叶的产量和茶叶生产的经济效益。茶叶产量比对照增加5.44%～13.88%,经济产值增加3635～5717元/hm2,增幅达到10.00%～15.72%。
The experimental result of the effects of application of various Kermira compound fertilizer on the yield and quality of the tea leaves shown that the different treatments with different ratioes of N,P,K significantly increased the available nutrient contents of P and K in the soil but decreased the N content in the soil compared with the control treatment applied nitrogen fertilizer only.Application of Kermira fertilizer also increased the contents of N,P,K in the tea leaves.Furthermore,it advanced some biophysical and biochemical indexes,which resulting in improvement of the quality of tea leaves.Application of Kermira fertilizer increased the yield and the income of the tea leaves by 10.0%-15.7% and by 3635-5717 yuan(RMB)/hm2,respectively.
