茶树每产一茬茶叶时要消耗大量的养分,若不及时补施叶面肥,则树体的生长发育和新芽的萌发会受到严重的影响,致使新茶产量不高、品质不好。但喷肥的方法当否。关系到茶树树势恢复和新芽萌发的快慢与好坏。科学施肥的方法是:1.看树生长情况选择恰当的肥料。叶色发黄、生长较弱、有脱肥现象的茶树,以喷施氮肥为主,配施钾肥;叶色浓绿、生长旺盛的茶树,以喷施磷肥为主,配施钾肥;生长一般的茶树,以氮磷肥配合喷施为好。2.掌握好肥液的浓度。喷施的肥液浓度为:尿素0.5～1%,硫酸铵1%,过磷酸钙1～2%,硫酸钾
Tea tree produce a lot of nutrients for each crop of tea, if not timely foliar fertilizer, the tree growth and development of germination will be seriously affected, resulting in new tea yield is not high, poor quality. However, the method of spraying should be. Related to the recovery of tea tree and sprout germination speed and good or bad. The method of scientific fertilization is: 1. To see the growth of trees choose the right fertilizer. Leaf color yellow, weak growth, the phenomenon of tea to take off the phenomenon of spraying nitrogen-based, with potash; leaf color dark green, vigorous growth of the tea tree, mainly to spray phosphate fertilizer, with potash; general growth Tea tree, with nitrogen and phosphorus fertilizer spray as well. 2. Grasp the concentration of fluid. Spraying fertilizer concentration: urea 0.5 to 1%, ammonium sulfate 1%, superphosphate 1 to 2%, potassium sulfate
