The invention discloses a
eucalyptus seedling culture substrate. The
eucalyptus seedling culture substrate comprises the following components in part by weight: 35 to 40 parts of coconut shell
powder, 25 to 30 parts of
peat, 15 to 20 parts of
bentonite, 20 to 25 parts of attapulgite, 0.5 to 0.8 part of
soil water-retaining agent, 15 to 20 parts of
nutrient substance and 0.2 to 0.3 part of composite strain. A production process of the
eucalyptus seedling culture substrate comprises the following steps of: drawing silk from a coconut shell to generate fragments; crushing the fragments; sieving until the granular size is 10 to 20 meshes; performing salt exclusion; mixing 35 to 40 weight parts of the coconut shell
powder subjected to the salt exclusion, 15 to 20 weight parts of the
nutrient substance and 0.2 to 0.3 weight part of high-temperature-resistant fermenting strain; adding
clean water to stir and wet; stacking into a circular truncated cone shape; covering a membrane on the circular truncated cone so as to ferment; and after fermenting completely, adding the
peat, the composite strain, the
bentonite, the attapulgite and the
soil water-retaining agent according to the weight ratio to mix and stir uniformly to prepare into block shapes. The coconut shell
powder serves as a main
raw material, so the materials are obtained singly and easily, the
nutrient ingredients and the content are easy to control, and large-scale standard production can be performed easily.
