Best Seed Starter Tray Wholesale Price Saudi Arabia


In order to promote the growth of above-ground and root systems(32 cell trays bulk), all rare earth elements are weak alkali metals, which are easily fixed in the soil and lose their effects. Although the old leaves can also be produced, promote plant growth, the number is very small(20 cell trays bulk). Understanding the growth characteristics of various tree species will enable nursery workers to take timely technical measures to promote growth.

The hormones that stimulate the growth of seedlings are mainly produced from the new leaves of the seedlings(21 cell trays bulk). Terrestrial plants not only absorb mineral nutrients from the soil through the root system, but also absorb many water-soluble substances through the leaves(288 cell trays bulk). Chemical substances, foliar spraying of trace elements can improve the nutritional status of plants, and have less investment and quick results.(best seed starter tray wholesale price saudi arabia)


Seedlings older than two years old germinate first in the spring to produce hormones(gallon pot), which are transported down through the formation layer to stimulate the formation layer growth, so the diameter first appears a small growth peak. The hormones that promote the growth of seedlings are increased when the winter buds start to move(112 cell trays bulk). When the branches grow into the fast-growing period, the hormones are produced the most.


(best seed starter tray wholesale price saudi arabia)The early growth tree species are Pinus tabulaeformis(square grow pots), Chinese pine, Pinus koraiensis, Masson pine, Yunnan pine, Huashan pine, Hesong pine, Red pine, Chinese pine, Picea genus, Abies genus, Ginkgo biloba, ash, cork, and cork. Tan, Ma Tan, Ailanthus altissima, Walnut, Bancai, sumac and pear trees. After that, the first rapid growth peak appeared in high growth(200 cell trays bulk). It is one of the common methods for topdressing forest trees.


By the end of the seedling stage, the high growth rate gradually exceeded the root growth rate and entered the high growth rate(plastic plant pots wholesale suppliers). The root growth has several growth peaks in a year, and the root growth peaks are interlaced with high growth peaks(98 cell trays bulk). If the top-dressing period is delayed to May or even after June, the high-growth has ended, Pinus sylvestris, and top-dressing has no effect on high-growth(Figure 4-1).


For example, in order to increase the high growth of seedlings, spring-growing tree species should be top-dressed early(plastic plant trays wholesale). In summer and autumn, the root growth peak is after the high growth peak, and the root growth stop period is later than the high growth stop period(162 cell trays bulk). Seedling roots appear at the earliest in the spring peak growth, because the minimum temperature required for root growth is lower than above ground.(best seed starter tray wholesale price saudi arabia)


Observation of the seedling roots of Populus simonii in Beijing(greenhouse supplies pots), the growth stop period in autumn is in the middle and late October, about 5-6 weeks later than the high growth, and the roots have four peak growths in one year. The peak growth period of roots is close to or at the same time as the peak growth period of diameter(50 cell trays bulk). The amount of root growth is highest in summer, followed by spring and least in autumn.


(best seed starter tray wholesale price saudi arabia)Foliar application of rare earth can obviously promote the growth of seedlings(cheap plastic plant pots bulk), but different rare earths or different formulations of the same rare earth have different effects on seedlings of the same tree species. For example, the roots of pear seedlings start to grow when the temperature reaches around 0°C(105 cell trays bulk): the roots of peach and apple seedlings start to grow when the soil temperature reaches 3°C to 5°C.
