Cheap Plastic Plant Pots Manufacturers In Jamaica

Glass culture pictures usually use glass culture dishes with a diameter of 11-15 cm(7 gallon grow pots). In order to make more oxygen in the container, it is better to choose a culture dish with a larger diameter and often open for air exchange. Acid etched seeds, such as Lespedeza, acacia, black wattle, Phoenix, Gemu, Bauhinia, Hu Beizi, Zaoying, wuhanzi, poke tree, etc., have dense seed coat, are impermeable and difficult to germinate(15 cell propagation trays wholesale), so they can be pretreated by acid etching or scalding.

Before pretreatment, it is better to take a few samples and etch them in acid for different time, so as to find the most suitable etching time for this batch determination(nursery trays). The degree of acid tolerance of seed coat varies with species, and also varies with species of the same species. Sulfuric acid is extremely corrosive(plastic plant trays). Do not touch eyes, skin or clothes. Do not let water be full of concentrated sulfuric acid. Otherwise, it will cause severe reaction or even explosion.

(cheap plastic plant pots manufacturers in jamaica)The correct treatment time is the acid etching time with the most seeds, the dull seed coat and no obvious damage(1020 trays). It can be seen with the hand-held magnifying glass that if the treatment is excessive, the testa will be severely eroded, and even the endosperm (or cotyledon) will be exposed in some places(seed starter trays). In addition to eliminating the impermeability of seed coat, it can also kill bacteria, and concentrated sulfuric acid can be used for many times.

Industrial concentrated sulfuric acid is commonly used for acid etching (proportion 1.84, purity 95%). There are also some tree species, Korean pine, Fraxinus mandshurica and ash(15 gallon nursery pots). It is better to warm the layer for a period of time before low temperature stratification. Some species of seeds do not need to be soaked before germination, and can be directly dry sown, with better germination effect(black plastic plant pots). If the treatment is insufficient, the erosion will be too light, even shiny.

In order to understand the quality of seeds as soon as possible, biochemical methods can also be used to determine their viability or their excellence(5 gallon plant pot). Stratification treatment (precooling treatment) seeds of some tree species have endogenous dormancy, such as Pinus koraiensis, cypress, root tree, ash, Acer truncatum, Phyllostachys multiflora, etc(nursery plant pots). they usually need a period of low temperature under humid conditions before germination.(cheap plastic plant pots manufacturers in jamaica)

Some tree species, such as Photinia glauca, require higher temperature for stratification, which is called warm stratification(72 cell seed trays). Generally, the temperature of warm stratification is 15 ℃ ~ 25 ℃ or 20 ℃ - 30 ℃. In the process of seed treatment, it is necessary to check frequently and turn frequently to facilitate ventilation. If the water is insufficient, add water properly(1 gallon nursery pots wholesale). The disadvantage of this method is that it is not very safe. Be careful when operating.

(cheap plastic plant pots manufacturers in jamaica)In order to promote germination, seeds should be soaked before germination test(square nursery pots). The water content of seed soaking is about 3 or 5 times of seed volume. The temperature of the water is 45 ℃, soaking seeds in natural cooling for 24 hours, some tree seeds may take longer(2 gallon nursery pots wholesale). The seeds with poor seed coat permeability can also be scalded. Before scalding, the appropriate temperature and time should be measured.
