Preparation method and application of plant stem cell modifier

The invention relates to a preparation method and application of a plant stem cell modifier. The preparation method comprises the following steps: step 1) raw material selection; 2) identifying and isolating; 3) biological culture; 4) extracting stem cells; (5) culturing plant stem cell mother liquor; and 6) producing a plant stem cell product. The method has the beneficial effects that (1) the modifier mainly comprising the plant stem cells is successfully prepared; 2, when the plant stem cell modifier is applied to flue-cured tobacco production, the plant stem cell modifier is found to have a remarkable effect on increasing agricultural parameters, yield and economic character indexes of flue-cured tobacco growth. And 3) the application of the plant stem cell modifier shows that the effect is optimal under the treatment of 200kg/mu of the plant stem cell modifier. 本发明涉及一种植物干细胞改良剂的制备方法及其应用，所述制备方法包括以下步骤：步骤1)原料选取；步骤2)识别隔离；步骤3)生物培养；步骤4)干细胞萃取；步骤5)植物干细胞母液培养；步骤6)植物干细胞产品生产。本发明的有益效果为，1)本发明成功制备了以植物干细胞为主的改良剂；2、使用该植物干细
