Valve leaf tree species developed from seeds to seedlings(rooting tray), cotyledons were unearthed but true leaves did not appear (seeds of cotyledon window soil, true leaves were not unfolded); conifer seed leaves were unearthed, seed coats were not shed yet and there were no primary leaves, needles, broad-leaved tree species, generally underground There is only the main root and no lateral roots(32 cell plug trays supplier). The number and area of leaves are increasing rapidly.

The true leaves grow from the ground of the young head, and the lateral roots grow underground, until the high growth of the seedlings rises greatly(v15 nursery pots). If these needs in the seedling stage can be met, the quality of seedlings and the yield of qualified seedlings can be improved. Therefore, it is necessary to start a nitrogen fertilizer at the seedling stage(200 cell seed starting trays). Attention should be paid to preventing late frost and high temperature hazards. varies greatly depending on the tree species.
(best plastic potting containers wholesale suppliers taiwan)The rapid growth period of spring seedlings of northern tree species is mostly between June and August, about 1 month to 2.5 months(nursery tray). Especially for seedlings susceptible to cataplexy disease, preventive measures should be taken in a timely manner. During this period, the seedlings are young and have weak resistance to excessively high and low temperatures(3.94inch plastic plant pots). The seedlings are exposed to phosphorus and nitrogen It is more sensitive.
During this period, the ground grows slowly, while the roots grow fast(germination tray price). The transition period of seedlings from the seedling stage to the fast-growing stage, the continuous growth tree species such as poplar, the average high growth of the next 5 days is 50%-100% larger than the average growth of the first 5 days(72 cell propagation trays). The aboveground part of the seedling grows true leaves or primary leaves, and the lower part of the ground produces lateral roots.
At this time, the nutrient source of the seedlings all depends on the nutrients produced by itself(72 cell plant tray). The main purpose is to create favorable conditions for the seedlings to be unearthed, so that the seedlings can be unearthed early. The growth of the above-ground parts and roots is the period with the most year-round(4.13inch plastic plant pots). The length of the fast-growing period and the coming sooner or later have a direct impact on the growth of seedlings.(best plastic potting containers wholesale suppliers taiwan)
Taking Populus simonii planting seedlings as an example(heavy duty plug trays), the yield of first- and second-class seedlings that began to topdress at the bacterium stage increased by 16% compared to the beginning of topdressing at the beginning of the fast-growing period. Until the high growth rate drops significantly. The seedlings are in the fast-growing period, and the aboveground and root growth is the largest(32 cell seed starter trays). Pay attention to the prevention of pests and diseases.
(best plastic potting containers wholesale suppliers taiwan)Such as Populus simonii, Robinia pseudoacacia, larch, Chinese fir and bubble maple and other planting seedlings(72 cell flats), high growth in the fast-growing period, accounting for 60% to 80% of the annual high growth. The seedlings have developed root systems and lush foliage during the fast-growing period, which has formed a developed vegetative organ(200 cell seed starter trays). The root system can absorb more water and various nutrients, and the ground can produce a lot of carbohydrates.
The seedlings of the southern tree species spring sowed in June to September, about 3 to 4 months, such as the Chinese fir in Fujian can reach more than 4 months(50 cell tray). In terms of environmental conditions, the temperature is relatively high, the temperature and moisture of the soil are suitable, and the relative humidity of the air is large, which is most suitable for the growth of seedlings(105 cell plastic propagation tray wholesale price). It is a critical period that determines the quality of seedlings.
