The loose soil, preferably half sand and half soil, shall be put into shallow body or wooden box after screening to form germination bed(long life propagation trays). No seeds shall be mixed in the soil, and the pH value shall be in the range of 6-7.5. Soil shall not be reused. The earth bed is wet with wine. After seeds are sown, they are placed outdoors in sunny and leeward places, and moved indoors in rainy days and after 4:00 p.m(2 gallon pots distributor). After the pure seeds are fully mixed, the samples are extracted according to the random principle.

The germination box is a non-toxic, colorless and plastic transparent germination container, with a hole partition inside(nursery tray manufacturers). The length and width of the box should be able to accommodate 4 or at least 2 repeated seeds. In addition, when the seedlings grow out of the ground, the dish cover needs to be opened gradually. The dead seeds become soft, discolored and moldy at the end of the period, and there is no evidence of seedlings(3 gallon pots distributor). 25 seeds can be counted out from each part to form 100 seeds, which is 4 repetitions.
(plastic 72 cell plant tray wholesale suppliers ecuador)The germination bed is placed on the perforated partition, and the space between the partition and the bottom of the box is used for water storage to improve the relative humidity in the box(1.5 gallon nursery pots). The germination box shall be equipped with two systems of heating and cooling, with good heat insulation, light conditions required for germination and humidity control(plastic bonsai pots wholesale). The box height should be slightly higher than the height of the normal seedlings of the tested tree species.
Four replicates are randomly weighed from the samples submitted for inspection for germination measurement(1 gallon plastic nursery pots). The basic structure of seedlings refers to the necessary structure for the seedlings to maintain and grow into qualified seedlings. With different species, the seedlings are composed of specific combinations of the following basic structures(2.5 inch square plastic pots): roots, hypocotyls, cotyledons, primary leaves, nucleis, and buds of Gramineae and palmitaceae.(plastic 72 cell plant tray wholesale suppliers ecuador)
For example, the components of purity analysis are: pure seed 48.26g, waste seed 0.66g, inclusion 1.06g(rootmaker propagation trays). A paper bed is laid on the partition board in the box, on which the seed samples for inspection are directly discharged. If the humidity cannot be controlled, the germination box or glass culture dish shall be placed in the temperature box to hold the seed samples for inspection(5 gallon plastic nursery pots). Germination box is a sealed box which can control temperature, humidity and light.
After the seedlings are unearthed, the sample weight of Pinus tabulaeformis seed is 50g, the number of them should be checked and recorded(one gallon pot). Some small tools, such as silver, dropper, scissors, blades and hand-held magnifying glass, are needed for germination test. The samples needed for the determination of sample extraction and germination are extracted from the pure seeds separated during the purity determination(bulk buy plastic plant pots). The pure seeds can be divided into 4 parts by the quartering method.
(plastic 72 cell plant tray wholesale suppliers ecuador)Birch, Casuarina, mulberry, press, poplar and Paulownia have very small seed size and can be germinated by weight(2 gallon pots wholesale). Instead of the number of grains, the samples are extracted and measured by weight. Each strand is repeated once with 0.1-0.25g. When using the weight germination method, the germination test results are expressed by the number of normal germination grains per gram of seed samples within the specified time(4 inch plastic pots bulk), and the unit is grain / gram.
