This invention provides a method for inducing rooting in Vaccinium tissue culture seedlings based on expanded clay granules, comprising the following steps: S1, preparing an aminated expanded clay granule-endophytic bacteria fermentation composite carrier; S2, preparing an expanded clay granule-gel composite substrate containing the aminated expanded clay granule-endophytic bacteria fermentation composite carrier; S3, after pretreatment of Vaccinium adventitious buds, aseptically inoculating them into the expanded clay granule-gel composite substrate, and culturing them at 22-24℃ and a light intensity of 1500-2000 Lx for 35-45 days to induce rooting; S4, after hardening off for 3-5 days, transplanting them into a mixed substrate of peat moss and perlite for acclimatization and cultivation for 15-20 days. This invention, using an aminated expanded clay granule-endophytic bacteria fermentation composite carrier and an expanded clay granule-gel composite substrate to induce rooting, can promote root primordia differentiation, stabilize the root growth microenvironment, standardize culture conditions to ensure stable rooting, and harden off for seedlings to enhance their stress resistance and adaptability, effectively improving the rooting quality and transplant survival rate of Vaccinium tissue culture seedlings, providing technical support for their efficient seedling cultivation.

This invention discloses a permeable ecological dam, a farmland irrigation system, and a method for regulating water levels in ditches. The permeable ecological dam includes multiple water-retaining dam segments arranged within the ditch, with the top height of the upstream water-retaining dam segment higher than the top height of the adjacent downstream water-retaining dam segment. Permeable dam segments are arranged between adjacent water-retaining dam segments, with the top height of the permeable dam segments falling within the range of the top heights of the adjacent water-retaining dam segments. Plants are grown on the top of the permeable dam segments. Multiple pipes are buried from bottom to top within the permeable ecological dam, with the upstream end of each pipe open for inserting a plug. Multiple permeable holes are provided on the pipes at the locations of each permeable dam segment, allowing water entering from the upstream of the ditch to pass through and enter the corresponding permeable dam segment. The water entering the permeable dam segment overflows to the downstream of the ditch. This invention can regulate the water level in the ditch to achieve multi-stage water level control and realize multi-stage permeability.
