氯吡苯脲是一种具有细胞分裂素活性的苯脲类植物生长调节剂，广泛于农业，园艺和果树，促进细胞分裂，促进细胞扩大伸长，促进果实肥大，提高产量，保鲜等。

氯吡脲的主要作用：
1、改善作物品质，提高商品性。诱导单性结实，刺激子房膨大，防止落花落果，促进蛋白质合成，提高含糖量等。
2、氯吡脲打破顶端优势，促进侧芽萌发，能够透导芽的分化，促进侧枝生成，增加枝数，增多花数，提高花粉受孕性，从而增加果实数量提高产量。
3、延缓叶片衰老，保绿时间长，加强叶绿素合成，提高光合作用，促使叶色加深变绿。
4、促进细胞分裂，促进果实膨大。对细胞的分裂有明显的促进作用，对器官的横向生长和纵向生长都有促进作用，从而起到膨大果实的作用。

Chlorfenuron is a kind of benzorea plant growth regulator with cytokinin activity, widely used in agriculture, horticulture and fruit trees, promoting cell division, promoting cell elongation, promoting fruit hypertrophy, improving yield, keeping fresh and so on.
The main effects of chlorfenuron:
1, improve crop quality, improve commodity. Induce parthenogenesis, stimulate ovary enlargement, prevent flower and fruit loss, promote protein synthesis, increase sugar content and so on.
2. Chlorfenuron breaks the apex advantage, promotes the germination of lateral buds, can penetrate the differentiation of buds, promote the formation of lateral branches, increase the number of branches, increase the number of flowers, improve pollen fertility, and thus increase the number of fruits and yield.
3, delay leaf senescence, keep green for a long time, strengthen chlorophyll synthesis, improve photosynthesis, make the leaf color deepen green.
4, promote cell division, promote fruit enlargement. It can obviously promote the division of cells, promote the transverse and longitudinal growth of organs, and thus play the role of enlarging fruit.
