细胞分裂素是一种植物生长调节剂 ,是国家科技部重点推广项目。细胞分裂素能直接被植物根、茎、叶吸收 ,刺激细胞分裂 ,促进叶绿素形成 ,促进光合作用 ,提高开花坐果率 ,增强作物的抗病能力 ,达到增产、增值的目的 ,特别是能增加早期产量 ,提高质量。细胞分裂素是一种使用浓度 Cytokinin is a plant growth regulator, the Ministry of Science and Technology is the key to promote the project. Cytokinin can be directly absorbed by the roots, stems and leaves of plants to stimulate cell division, promote the formation of chlorophyll, promote photosynthesis, increase the flowering rate and increase the resistance of crops to achieve the purpose of increasing production and increasing value, especially to increase the early Yield, improve quality. Cytokinin is a use concentration
