Berry rooting agent

The invention discloses a berry rooting agent and belongs to the field of small berry seedling culture. The berry rooting agent solves the technical problems that existing ABT rooting powder is low in rooting rate, small in rooting amount and long in rooting time. The berry rooting agent is composed of indolebutyric acid, absolute ethyl alcohol, NaOH and water. The concentration of the indolebutyric acid is 2000mg/L-2500mg/L, the volume concentration of the absolute ethyl alcohol is 50%, and the concentration of the NaOH is 0.6g/L-0.8g/L. The berry rooting agent improves the rooting rate of cuttage of hard branches and cottage of green branches, is fast in rooting and large in rooting amount. With the berry rooting agent, the rooting rate of cuttage of gooseberry hard branches is 84% or so, the rooting rate of cuttage of gooseberry green branches is 98% or so, and rooting is performed in a week after cuttage; the rooting rate of cuttage of black currant hard branches is more than 98%, the rooting rate of cuttage of black currant green branches is 100%, and rooting is performed in a week after cuttage; the rooting rate of cuttage of hippophae rhamnoides green branches is 100%, and rooting is performed in five days after cuttage.
