In order to use seeds scientifically and rationally, the following principles should be followed when allocating seeds(plastic plant trays wholesale): seeds should be allocated in the seed area and the most suitable source area should be selected. If there is no optimal source area, seeds should also be allocated in the vicinity of the afforestation area(40 cell propagation trays wholesale). Small differences. Soil management is the same as general nursery management.

At this time, the weight of the seed itself no longer increases or increases little, the respiration is very weak, the resistance is enhanced, and it is resistant to storage(plastic grow pots). For example, Chinese fir started to mature in the middle and middle of October in Central China, but it only became popular in November in Fujian, Guangdong and Guangxi(50 cell seedling trays wholesale). The division of seeds is to make the sources of afforestation seeds reliable and have clear records.
(cheap plastic v10 nursery pots suppliers saudi arabia)If the collection date is determined incorrectly, it will affect the yield and quality of seeds(square nursery pots). If there is no suitable source area in the vicinity of the afforestation area, the area with the same or similar climate and soil conditions as the afforestation area should be selected(36 cell propagation trays wholesale). Accurately identifying the heat generation period of the seed and understanding its shedding characteristics are the keys to determining the seeding period.
With a clear seed area(propagation tray), only the best provenance can be found during afforestation, avoiding the random use of seeds from any one of the provenances, causing poor growth of the trees and even afforestation failure. Afforestation must be suitable for suitable trees and suitable provenances(18 cell propagation trays wholesale). Only in this way can the afforestation be ensured to be alive and well, and the productivity of the forest land can be maximized.(cheap plastic v10 nursery pots suppliers saudi arabia)
When the seed embryo grows and develops into parts including radicle, germ, cotyledon, and hypocotyl, and has germination ability, the seed is mature(plug trays). Seed maturation includes two processes, generally through physiological maturity, and then into morphological maturity, but there are a few exceptions for tree seeds (Ginkgo)(12 cell propagation trays wholesale). When the embryo has developed to have the ability to germinate, it is called physiological maturity.
But in order not to affect the output of seed strips, it must be carried out in stages(gallon nursery pots). Provenance is based on the origin of a batch of seeds and their site conditions. Seeds of different provenances are afforested in the same area, and their survival rate, growth, wood properties and stand stability are very different(nursery plant pots). Therefore, the seeds of general tree species are collected when the form is mature, which is called morphological maturity.
(cheap plastic v10 nursery pots suppliers saudi arabia)The characteristics of seeds at physiological maturity are(gallon plant pot): high water content, the nutrients inside the seeds are in a soluble state, the seed coat is not dense, and the protective tissue is not sound, so it is difficult to prevent the loss of water, and the internal soluble substances are also easy to leak out of the seed coat(black plastic plant pots). Therefore, it is very important to correctly determine the appropriate seeding period.
The fruit has the normal size and color when mature, the seed coat is hard and dense, the moisture content of the seed is low, and the internal nutrients are transformed into the insoluble state(cell trays). The time for physiological maturity and morphological maturity of some tree species is almost the same, such as poplar, willow and other tree species(seed starter trays). It is susceptible to infection and loss of vitality, so it is not storable.
