在茶叶采摘期间,利用根外追施氮吧,可以提高茶叶产量,但对利用磷质和钾质肥料喷施茶树是否有增产效果,尚少进行研究。为了充分发挥各种肥料的增产作用,我站去年就氮、磷、钾三要素和人尿、尿素,进行增产效果对比研究,并取得了初步结果,现分述如下: 一、试验方法: 1.氮、磷、钾增产效果对比的试验区设置在综合
During the period of tea picking, the use of extra-root nitrogen fertilizer can improve the yield of tea. However, little research has been done on the use of phosphorus and potassium fertilizers to increase tea yield. In order to give full play to the role of a variety of fertilizers to increase production, last year I stood on nitrogen, phosphorus and potassium three elements and human urine, urea, compared the effect of increased yield and achieved preliminary results are as follows: First, the test method: 1 The experimental areas for comparing the yield increase effects of nitrogen, phosphorus and potassium are set in a comprehensive manner
