Embodiment 1
[0019] The volume ratio of rape straw, pastoral soil and vermiculite in the seedling raising matrix composition of this example is 2:2:6, and every 10m 3 Inorganic fertilizers need to be added to the substrate, and the weights in terms of pure nutrients are: nitrogen 180g, phosphorus pentoxide 60g, potassium oxide 120g. The nutrients in the inorganic fertilizer are provided by the following substances: nitrogen: urea; phosphorus pentoxide: calcium magnesium phosphate fertilizer; potassium oxide: potassium chloride.
[0020] Inorganic fertilizers converted into commercial fertilizers and the physical quantity of main raw materials are selected from the following substances (to produce 10m 3 In terms of seedling-raising substrates, the natural loss of the product during processing is not calculated. If natural loss occurs, the actual amount of each formula can be increased synchronously in proportion according to the conventional methods in this field, the same below):

Embodiment 2
[0025] The volume ratio of rape stalks, pastoral soil and vermiculite in the seedling-raising matrix composition of this example is 3:2:5, and every 10m 3 Inorganic fertilizers need to be added to the substrate, and the weights in terms of pure nutrients are: 150g of nitrogen, 50g of phosphorus pentoxide, and 90g of potassium oxide. Nutrients in the above inorganic fertilizers are respectively provided by the following substances: nitrogen: urea, phosphorus pentoxide: calcium magnesium phosphate fertilizer, potassium oxide: potassium chloride.
[0026] The above-mentioned inorganic fertilizers are converted into commercial fertilizers and the actual amount of main raw materials is selected from the following materials (to produce 10m 3 In terms of seedling-raising substrates, the natural loss of the product during processing is not calculated. If natural loss occurs, the actual amount of each formula can be increased synchronously in proportion according to the conventional me...
