Application Of Fertilizer After Mulching By Ridging Film Mulching Machine

(1) Topdressing

After the film is covered by the ridging film mulching machine, the fertilizer can be applied in the rainwater ditch or in the hole during fertilization and growth. First remove the mulch in the rainwater collection ditch, and then dig the rows or holes 3 to 5 cm from the edge of the film according to the depth of fertilization. After fertilizing, backfill the soil at the original trench bottom height, and take the mulch back to its original location. This topdressing can achieve the coupling effect of "water-fertilizer".

(2) Fertilizer application

After the ridging film mulching machine is applied to the base fertilizer in autumn, if the film surface is maintained well, the mulching film has low differentiation and few holes, and can be continued to be used until the second year. When basal fertilizer is applied, it can be dug and applied in the rainwater collecting ditch. After fertilizing, backfill the soil at the original trench bottom height, and take the mulch back to its original location.
