花卉对其中一些元素需要量较大,如氮、磷、钾等,称大量元素;对另一些元素需要量相对较小,如镁、锌、锰、铁、铜、硫、硼、钼等称微量元素。花卉所需的微量元素,其功能各不相同,如果某种微量元素缺乏,就会引起花卉生理机能的紊乱,导致花卉出现症状,影响叶色和花姿,甚至使植株衰弱以至死亡。下面介绍花卉缺乏微量元素的症状及矫正方法,供参考。 Some of the elements such as flowers need more, such as nitrogen, phosphorus, potassium, said a large number of elements; for other elements of relatively small, such as magnesium, zinc, manganese, iron, copper, sulfur, boron, molybdenum, etc. Trace elements. The trace elements needed by flowers have different functions. If some trace elements are lacking, the physiological functions of flowers will be disturbed, causing the flowers to have symptoms, affecting the leaf color and flower pattern, and even weakening the plants to death. The following describes the lack of trace elements of flowers and symptoms of correction methods for reference.
