First, find varieties. Nowadays, many people who sell seedlings are farmers without professional training. They don't know much about the scientific names of plants, and they all use local common names. However, the common name of some plants is just the same as the scientific name of another plant, not the same plant. For example, Spiraea, commonly known as Pearl Plum in some places. . Some seedling suppliers use fraudulent means to replace the seedlings of purchased varieties with similar varieties, such as Ailanthus altissima, Feng Rose and single-petal varieties instead of double-petal varieties. So if you don't carefully check the varieties of seedlings, it will easily lead to varieties errors and delay the construction period.
Second, look at the quality. After the seedlings arrive, pay attention to observe whether there is water loss. Mainly depends on its roots and branches and leaves, once the seedlings lose water, the survival rate will be seriously affected, especially after long-term transportation. Pay attention to the inspection of plant diseases and insect pests. Leaf pests and diseases are easy to find, but branch pests are often ignored, especially some stem borers that invaded in that year are not easy to find, and branch pests often exist in larger seedlings, and should be eliminated on the spot once found. Check the roots carefully for damage. For seedlings that need soil balls, check whether the soil balls are in good condition and whether the specifications meet the requirements. For small-sized seedlings, we should also pay attention to the phenomenon that some seedling suppliers wrap their roots with soil instead of soil balls, which is not conducive to the survival of seedlings. For deep-rooted seedlings, especially those with large specifications, special attention should be paid to checking whether the root system is damaged or not. When the seedlings arrive at the site by transportation, we should pay attention to check whether there is skin damage or splitting on the branches and stems and whether there is splitting at the roots. If there are many skin injuries, it will affect the transportation of nutrients and water in the tree, which is not conducive to the survival of seedlings and the root system is seriously damaged, which is not suitable for new roots and survival.
Third, when the construction period is tight and the number of seedlings is large, it is best to go to the field to see the seedlings. The first is to see if the supplier really has the source of goods; The second is to see whether the varieties and specifications of seedlings meet the requirements, so as to avoid mistakes in missing the planting season and delaying the construction period.
Nursery workers, because of the differences in varieties and regions, need to find sources of goods all over the country. It is particularly important to find a well-known and trustworthy flower and tree broker in the local area. He can find local unique seedlings for us, save a lot of unnecessary time and energy, and learn a lot of useful knowledge from him. Although he will take part of the agency fee, it is still worth it.
