Heavy Duty Greenhouse Plant Starter Trays


It also limits the growth space of the root system(cell trays). While the seedling holes are small (the number of holes per plate is large), the seedling seedlings are sensitive to changes in substrate moisture, nutrients, oxygen, pH, etc., and at the same time, the seedlings compete more vigorously for light and nutrients, but the amount of the substrate is less(greenhouse supplies pots). Production costs are lower. The quality of the matrix is one of the key factors for the successful seedling cultivation.(heavy duty greenhouse plant starter trays)


The clean substrate used for the first time is generally not disinfected(gallon nursery pots). In cucumber seedlings, the seedlings of 4 to 5 leaf seedlings were selected from 128-well seedling trays; the seedlings of 6-leaf seedlings were selected from 72-well seedling trays or 50-well seedling trays. In summer, 3 leaves and 1 seedlings are selected from 200-well or 288-well seedling trays(plastic grow pots). The first true leaves of cucumber seedlings in the long winter season are grafted when they are unfolded, so 72 holes can be used.


(heavy duty greenhouse plant starter trays)In winter and spring, 2 leaves and 1 seedlings are selected from 288-well seedling trays(gallon plant pot). Because of the independent growth space of roots of each seedling in seedlings, and the growth space is much smaller than the traditional seedlings, the limited seedling substrate reduces the water and nutrients(flat plastic tray). The buffering capacity, therefore, the growth environment of the root system is very different from the traditional seedbed growth environment, and the quality of the matrix is high.


Different sizes of plugs have great influence on seedling growth and suitable seedling age(black plastic plant pots), and the seedling holes are large (the number of holes per plate is small), which is conducive to the growth of seedlings, but the dosage of the substrate is large and the production cost is high. Therefore, in the production of seedlings, appropriate plugs should be selected according to factors such as the type of vegetables(7 gallon nursery pots wholesale), the size of the seedlings, the growth rate of different seasons, and the length of the seedlings.


(heavy duty greenhouse plant starter trays)At present, most of the substrates used in the production of seedlings are mainly grass charcoal, vermiculite and perlite(plug trays). Perlite is 3:1, because the seedling age is shorter, 1~1.5kg of compound fertilizer is added per cubic meter of matrix (if it is winter and spring seedlings, 2kg of compound fertilizer should be added per cubic meter of substrate), or 1.5 per cubic meter of matrix. Kg urea and 1.2kg potassium dihydrogen phosphate(10 gallon nursery pots wholesale), the fertilizer and the substrate are mixed uniformly and used.


Stir it evenly with iron shovel, and put the mixed substrate into the seedling tray when you hold it in a hand and spread it out(square nursery pots). Make sure that each hole is filled with the substrate, then use a wooden board to smooth the tray. The grid of the tray can be exposed. Place the tray filled with the substrate on the ground, place a hole plate on it, press it evenly under pressure, and press it down to 1.0~1.5cm(wholesale greenhouse pots), or directly press the small hole of 1.5cm deep in the center of each hole with your fingers.


Spray some water with a watering can(propagation tray). In addition, producers can take local materials according to local conditions and make full use of some wastes in agricultural production, such as fungus residue produced from edible fungi, coco peat, crop straw crushed material, vinegar grains, etc. instead of peat. The reusable substrate is preferably sterilized(seed starter trays). It can be immersed in 0.1% to 0.5% potassium permanganate solution for 30 minutes and then washed with water.(heavy duty greenhouse plant starter trays)
