The invention discloses a rice
seedling raising
organic matrix, and belongs to the technical field of rice
seedling raising. The matrix comprises a vinegar residue, cassava residue and
straw powder fermentation-treated mixture, a coconut
chaff wet material,
plant ash,
peat and
vermiculite. The matrix comprises 3-6 parts of the vinegar residue, cassava residue and
straw powder mixed organic
fermentation material, 1-2 parts of the coconut
chaff wet material, 1-2 parts of the
plant ash, 1-2 parts of the
peat and 0.5-1 part of the
vermiculite, and according to the
material volume, a compound
fertilizer and a synergistic agent and a stocky agent are added. The matrix comprises 2-4% of total
nutrient, 40-50% of water, the total
porosity is 65-75%, the volume weight is 0.35-0.5 g / ml, the particle
diameter is less than or equal to 5mm,
organic matter content in the dry matrix is more than or equal to 30%, the EC Value is 1.0-2.0 mS / cm, the gas water ratio is 1:2-4, and pH is 5.5-7.0. The matrix is a granular
solid which is brown or black brown in appearance, and free of peculiar smell. The rice
seedling raising
organic matrix is prepared from vinegar residue, cassava residue,
straw, coconut
chaff and other organic waste as raw materials, is comprehensive in
nutrient, stable in quality, and suitable for rice seedling raising, and can promote the robust growth of the seedlings.
