Cheap 20 Cell Seed Starter Tray Wholesale


It can be mechanized once, or mechanically, and other procedures can be done manually(288 cell propagation trays wholesale). When the conditions are not available, all can be done manually. On the basis of the fertilizer applied to the matrix, it is generally no longer applied. When the fertilizer is lacking, the surface can be sprayed with 0.2% compound fertilizer. On the basis of watering after sowing, the winter seedlings cover the seedling plate with moisturizing, and the water can not be watered before emergence(plug trays wholesale). In the summer, the seedlings should be poured with small water before the seedlings are unearthed to keep the upper substrate moist.


After emergence, the first true leaf is displayed, and the water content should be reduced to prevent the length(200 cell propagation trays wholesale). It then grows with the plant and increases the amount of water. Water is irrigated 1 day before the day of the seedling or on the same day. There are two kinds of simple formulas and fine formulas. (1) Simple formula: mainly to provide the necessary large amount of elements and iron for the vegetable seedlings, and the trace elements are provided by watering and seedling substrates(black plastic nursery pots). Fine formula: mainly based on simple formula, add appropriate amount of trace elements.


(cheap 20 cell seed starter tray wholesale)The amount of the main trace elements is as follows(20 cell propagation trays wholesale): boric acid: 1.43 mg / L; manganese sulfate tetrahydrate: 1.07 mg / L; zinc sulfate heptahydrate: 0.11 mg / L; copper sulfate pentahydrate: 0.04 mg / L; ammonium tetrahydrate molybdate: 0.01 mg / L. There is also a simpler nutrient solution formula which uses NPK ternary compound fertilizer (NPK content 15-15-15) as raw material, and the cotyledon stage is watered with 0.1% solution, and the true leaf stage is 0.2(plastic nursery pots wholesale). Watered at a concentration of % to 0.3%.


The formula is mainly used for seedling cultivation of mixed charcoal and vermiculite with high nutrient content(112 cell propagation trays wholesale). The nursery site and main equipment should be disinfected before breeding. Sulfur fumigation can be used in greenhouses and greenhouses. The nursery trays can be disinfected with 50 to 100 times of formalin solution, and then washed several times with water to dry(plastic nursery pots). The substrate generally does not have to be sterilized, but the contaminated substrate can be sterilized with 0.1% to 0.5% potassium permanganate or 100 times formalin solution.(cheap 20 cell seed starter tray wholesale)


Wash thoroughly after disinfection to avoid damage to seedlings(162 cell propagation trays wholesale). Place the seedling tray in a 2 to 3 cm thick substrate. After the substrate is poured with water, the seed that has been germinated or soaked is evenly spread, covering the substrate 0.5 to 1 cm. After sowing, it is placed in an electric germination chamber, and the temperature is controlled within a suitable range of seed germination(plastic nursery pots manufacturers). Immediately after the seedlings are unearthed, the seedling trays are moved into the greenhouse for greening and appropriate cooling. After the cotyledons are flattened, the nutrient solution is poured in time.


(cheap 20 cell seed starter tray wholesale)The amount of nutrient solution is fully wetted by the substrate, and the bottom layer has a nutrient layer of 1 to 2 cm(128 cell propagation trays wholesale). 3 to 4d poured a nutrient solution, the intermediate matrix is too dry to replenish water. Before the seedlings are transplanted, the nutrient solution is poured. After the seedlings are moved, the liquid layer of 1 to 2 cm deep is often maintained, and the amount of liquid supply is reduced one week before the planting, and the seedlings are exercised(wholesale nursery pots). Plug seedlings are a modern seedling system with a light material such as peat, vermiculite, and mechanized precision seeding.
