'variegata'container seedlings

Abstract

The invention provides a special culture substrate for pittosporum tobira 'variegata' container seedlings, belonging to the technical field of horticulture settings. The substrate contains the following components by volume percent: 35-45% of peat, 15-25% of medical stone, 5-15% of perlite and 25-40% of yellow subsoil, wherein 500-1000g of ground ginkgo leaves are added to the culture substrate per cubic meter. The substrate has the beneficial effects of having an obvious effect of promoting growth of annual container seedlings of pittosporum tobira 'variegata' and being high in height increment; the ground ginkgo leaves can promote root growth; the volume weight of the substrate is adjusted by adopting medical stone, so the substrate is more suitable for the needs of plant culture; medical stone is also used for adjusting and improving the total porosity, water-holding porosity and aeration porosity of the substrate; meanwhile, in the irrigation process, macroelements, such as potassium, calcium and magnesium, and trace elements, such as iron, copper, zinc and manganese, are dissolved out of medical stone after medical stone is leached with water, thus reducing the application amount of macroelement chemical fertilizers and reducing the production cost; the substrate can be used for scale production of pittosporum tobira 'variegata'.

Description

technical field [0001] The invention belongs to the technical field of horticultural facilities, and in particular relates to a special cultivation substrate for Pittosporum mosaic container seedlings. Background technique [0002] The soilless cultivation substrate can provide a stable and coordinated growth environment for plants. In addition to supporting and fixing the plants, it can also "transfer" the nutrients and water in the liquid fertilizer, so that the roots of the plants can absorb water and fertilizer according to their needs. Although the EC, pH value and nutrient concentration of the liquid fertilizer can be precisely controlled, the plant root system is in contact with the substrate and absorbs water and nutrients from the substrate. The physical and chemical properties of the substrate and the adsorption characteristics of the liquid fertilizer directly determine the management technology and nutrition of the plant. Therefore, both domestic and foreign coun...
