Buy seeds five attention
In recent years, especially the Magnoliaceae tree species in the Jiangnan area has been deeply loved by the landscaping department and the majority of seedling growers. Magnoliaceae trees are rich in species, and there are different tree species in the same genus. Some seeds are similar in appearance and difficult to distinguish, and they are often prone to counterfeiting. In particular, Magnoliaceae plants can also be cultivated by asexual propagation methods such as grafting and cutting. Therefore, when collecting seeds, in order to prevent and reduce the occurrence of counterfeit and substandard seed events, it is necessary to remind the farmers and farmers to pay attention to the following issues. 1. Pre-seed seed maturity is important. Grasping the conventional seed collection time of tree species is forbidden. It is forbidden to collect different seeds for sale together. 2. Selection of provenances and analysis of anti-freezing ability against damage. The tree species in different climatic regions must be tested and promoted first. Seed seedlings harvested from the warm southern region grow fast, have weak frost resistance and are prone to frost damage. This should be noted. 3. The name of the species should be consistent with the seeds sold. The pictures or collected specimens should be consistent with the seeds for sale. Really confused. 4. The preliminary identification of seed quality can be performed by anatomical methods to determine the quality of the seed based on the quality of the embryo and endosperm. Tetrazole and indigo can be used to determine the viability of seeds. 5. When buying seed, it is necessary to issue an invoice and make a warranty (contract or agreement) indicating the species name, origin, character, quantity, etc. of the seed. Farmers who have difficulties in identifying seeds must not be blindly or easily purchased. Problems should be promptly reflected in order to reduce unnecessary losses.
