Embodiment 1

[0086] Example 1

[0087] The pepper seedling cultivation mushroom dregs composite cultivation substrate described in the present embodiment 1 comprises by volume: 6 volumes of mushroom dregs, 0.5 volume of vermiculite, 1 volume of perlite, and 3 volumes of peat. Among them, the C / N ratio of mushroom dregs is 25:1, and the amount of urea added is 2.13g. The particle size of the vermiculite is 3 cm. The particle size of the peat is 6cm. The particle size of the perlite was 2 cm.

Embodiment 2

[0089] The pepper seedling cultivation mushroom dregs composite cultivation substrate described in present embodiment 2 comprises by volume: 6 volumes of mushroom dregs, 0.5 volume of vermiculite, 2 volumes of perlite, and 2 volumes of peat. The C / N ratio of mushroom dregs is 30:1, and the amount of urea added is 0.99g. The particle size of the vermiculite is 5 cm. The particle size of the peat is 4cm. The particle size of the perlite was 2 cm.

Embodiment 3

[0091] The pepper seedling-raising mushroom dregs composite cultivation substrate described in Example 3 includes, by volume: 6 volumes of mushroom dregs, 1 volume of vermiculite, 0.5 volume of perlite, and 3 volumes of peat.

Abstract

The invention relates to a composite culture medium of pepper seedling culture mushroom residues. The composite culture medium comprises mushroom residues, vermiculite, perlite and turf, wherein the mushroom residues, the vermiculite, the perlite and the turf are proportioned according to the volume ratio of 6-10: 0.5-2: 0.5-2: 0.5-3. The composite culture medium has the physicochemical propertiesof volume weight of 0.27-0.54g / cm < 3 >, total porosity of 69.21-92.69%, ventilation porosity of 22.08-33.72% and water holding porosity of 47.13-64.47%, which shows that the composite culture medium has good air permeability and high water holding capacity. The composite culture medium has the chemical properties of EC value of 3.95-5.41 microseconds / cm and pH value of 7.38-7.63, which shows that the composite culture medium is suitable for seedling culture. By using the composite culture medium for culture, the roots of seedlings grow well and grow well.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a composite cultivation substrate for pepper seedling cultivation and mushroom dregs. Background technique [0002] With the development of science and technology and the improvement of living standards, people's demand for agricultural products is also increasing, and the floor area of ​​vegetable greenhouses needs to be larger and larger. In order to alleviate the pressure of soil rotation sowing, a lot of research has been done on the substrate of soilless culture at home and abroad. Soilless cultivation refers to a crop cultivation method that does not use natural soil, but directly fixes plants with nutrient solution or inorganic substrate, and waters the nutrient solution to provide the nutrients, water and oxygen required for plant growth. In this method, the solid matrix can be divided into inorganic matrix and organic matrix. Inorganic matrix refers to some...
