The quality of forest tree seeds is directly related to the yield of seedlings and affects the growth of forest trees(3 gallon nursery pots wholesale). The extracted samples must be sufficiently representative, otherwise even if each inspection item is done very meticulously and accurately, the results will not reflect the quality of the entire batch of seeds and will mislead production(3.5 inch square plastic pots). The extra-large seeds such as walnuts, chestnuts, socks, and tung tree are 10,000 kg. Therefore, the sampling technique must be properly mastered.
(double color plastic plant pots wholesale suppliers latvia)Different plant growth regulators sometimes get better results when used together(5 gallon nursery pots wholesale). The so-called same batch means that the seeds of one batch must meet the following five conditions: one is the seed of the same tree species, and the other is the range of the same county(6.35cm square grow pots): three is the same seed collection period, the same processing, modulation and storage method, four After the seeds are fully mixed, the ingredients that make up the seed batch are uniformly and randomly distributed.
The large seeds, such as Camellia oleifera, mountain apricot, bitter core, etc., are S000 kg, and the middle-pull seeds(7 gallon nursery pots wholesale), such as Korean pine, Huashan pine, plum, and jujube, are 3500 kg. P. tabulaeformis, larch, Chinese fir, locust tree, etc., 1000 kg, extra-small teaching seeds such as school trees, mulberry trees, Paoqun, Casuarina, etc., 250 kg(v9 nursery pots). Sampling principle Sampling must be carried out in the same batch of the same tree species.(double color plastic plant pots wholesale suppliers latvia)
Mixed samples: All the initial samples taken from the same batch are combined together and mixed thoroughly to become a mixed sample(10 gallon nursery pots wholesale). The third is through strict seed inspection to prevent unqualified seeds, especially those with substandard water content and seeds infected with diseases and insect pests, from being used, stored or allocated to avoid loss and spread of diseases and insect pests(plant trays without holes). Fifth, a seed batch must have a certain weight.
(double color plastic plant pots wholesale suppliers latvia)During seed soaking, the water should be changed 1 to 2 times a day; after the seed embryo completes the maturation process(15 gallon nursery pots wholesale); the low-temperature stratification and germination process is consistent with the pre-seed process of the seed, which is helpful for lifting dormancy. The samples submitted for inspection are stipulated by the national standard according to the seed size and the thousand-grain weight(plastic nursery trade pots). When soaking, the water should be less than about 3cm.
Sampling method is correct and fragrant, which is the first condition for seed test to obtain correct results(20 gallon nursery pots wholesale). To this end, the State Forestry Administration organized 13 units including the Forestry Research Institute of the Chinese Academy of Forestry to study and formulate the "National Standard for Forest Tree Seed Inspection Procedures GB2772-1999)(plant plastic trays). The weight of the mixed sample is preferably not less than 10 times the weight of the sample submitted for inspection.
