(bulk buy cheap plastic five gallon planter mexico)Some seeds with excessive drying have high water content, such as excessive water loss(plug trays). In production, we should pay special attention to the determination of water content of seeds before purchase and storage. In the process of purchasing, allocating and using seeds, we can avoid the huge loss of economic and ecological benefits caused by using inferior seeds(nursery plant pots). The classification of forest seed quality is of great significance in the production.


The inferior seeds have the following sensory manifestations(square nursery pots): the seeds are shrunk or shriveled, lose the unique color, elasticity and smell of the fresh seeds of the tree species, or are mothed, or have mildew symptoms, or have peculiar smell, or have mildew. When the teeth bite, the seeds become soft but not brittle, and even the bite fan does not crack(large plastic terracotta pots), and the water content indexes must be determined for seed acquisition, transportation and temporary storage.

The seed shells of rarefied trees, wiped wood, Magnolia officinalis, Magnolia, etc. are fragile, the seed shells of plate vegetables are soft and sweet, and the taste of walnuts is fragrant(4.5inch square nursery pots).
