Therefore, seed quality inspection generally refers to the inspection of seeding quality(72 cell seedling trays wholesale). Usually a batch of seeds is used as an inspection unit for seed quality inspection. This method is suitable for southern areas where the temperature is high, the precipitation is large, and the seeds buried in the open air are easy to mold(deep propagation trays). The same batch of seeds has the following conditions: good quality seeds, high germination rate, regular germination, strong seedling growth and high yield.

Practice has proved that for the seeds of most tree species, the temperature is controlled within the range of 0-5 ℃ the most suitable for storage in the country(105 cell seedling trays wholesale). Generally, the water content of the inclusions is high, and the hygroscopicity is also strong, so that the seeds are easily rotted by moisture(lavender plug trays). Therefore, the moisture content of the seeds can also be controlled to reduce the harm to the seeds when the temperature changes drastically.(best 8 inch plastic plant pots manufacturers ireland)
The method is: first put some water on the ground, spread a layer of wet sand about 10m thick(128 cell seedling trays wholesale), and then mix or layer the seeds and wet test sand according to the volume ratio of 1: 3, pile up 50-80am high and 1m wide, The length of the pile depends on the size of the indoor area. Insert a bunch of straw or perforated bamboo tube every lm in the middle of the pile for ventilation(plastic plant pot suppliers). The seeding quality includes seed physical traits, germination ability, viability and goodness.
Seed batch is also called seed batch(162 cell seed starting trays). Collected on a similar site condition within a county (forestry bureau), commune (forest farm) or in the same improved seed base; the age and age of the seeds are about the same, the time of the seeds is about the same, the processing and storage methods of the seeds are the same, the weight Do not exceed the following limits(plastic plant pots manufacturers). Generally, it can only be emphasized that seeds are collected from mother trees with good traits.
(best 8 inch plastic plant pots manufacturers ireland)In order to ensure and improve the quality of seeds and reduce the loss and waste of seeds(128 cell plastic propagation tray wholesale price), all units that operate and use seeds must undergo seed quality inspection during harvesting, storage, modulation and sowing. Genetic quality refers to the sum of all overpass factors (genes) passed from parents to offspring. It is difficult to discriminate based on the internal and external traits of seeds(plastic terracotta pots wholesale). It is a category of genetic breeding research.
Seed quality includes genetic quality and sowing quality(200 cell seed starting trays). Extra-large seeds (nuclear cross, chestnut, oil paste, etc.) are 10000kg; large-grain seeds (Ma general, mountain apricot, camellia, etc.) are 5000kg; medium-sized seeds (Korean pine, Huashan pine, sparse tree, sand date, etc.) are 3500kg : Small-grain seeds (Pinus tabulaeformis, larch, Chinese fir, Robinia pseudoacacia, etc.) is 1000kg(110mm plastic grow pots); extra-small-grain seeds (core, mulberry, Paulownia, Casuarina, etc.) is 250kg.
From this we can see that correctly identifying the seeding quality of the seeds and understanding the use value of the seeds are important means to move the production and management of the seeds to scientific management(15 cell trays bulk). If the weight of the seed batch exceeds the eye amount, a separate seed batch should be allocated. However, the concentration of seed production areas can be appropriately increased(11cm plastic grow pots). There should be a passage between the heaps for inspection.(best 8 inch plastic plant pots manufacturers ireland)
