Material and methods Materials.The main raw material of the plant bowl-seeding tray include rice straw, solid adhesives and other special substances, the seedling tray was made up of straw powder, fertilizer nutrient soil, biological glue and clay.
Preparation Methods of Seedling-Growing Tray Sample. 1 Four kinds of raw materials were weighed by electronic balance according to the needs of the trial design; 2 Raw materials were put in the blender and stired fully, until raw materials are mixed uniformity; 3 A sample of mixed materials was weighed and put in the self-made mold, WES hydraulic universal testing machine was used to press the sample into small round cakes(Fig. 4) with 85mm diameter and 3mm thicknes; 4 Small round cakes were removed from the mold, the sample of bowl seedling tray is completed.
