First, the introduction season should be suitable. This is the premise and guarantee of the survival rate of introduced seedlings. The introduction of seedlings has strong seasonality, and spring, autumn and winter are generally the best seasons for the introduction of seedlings. The seedlings introduced in time grow fast and strong, while the seedlings introduced in summer grow slowly and even hardly survive. Generally speaking, planting in winter is better than planting in spring. In the north, because of the cold winter climate, the soil will freeze, so it is best to plant it after the soil thaws in spring. Second, introduce and select seedlings according to local conditions. This is the decisive factor for the success of introducing seedlings. China has a vast territory and abundant resources, and there are also great differences in natural environmental conditions, technical capabilities and market conditions. No seedling variety can be suitable for the development of all parts of the country. Therefore, we should pay attention to local conditions, vary from variety to variety, and choose the most suitable seedling variety according to the local climatic conditions, soil quality, fertility and specific requirements of varieties. Third, we should select the imported units. When introducing, you should choose the legal introduction unit. Regular seedling sales units can guarantee the quality and quantity, issue formal invoices, give technical support, plant seedlings on a certain scale, and have industrial and commercial business licenses and seedling sales licenses or tax registration certificates. In addition, if the buyer of seedlings has the conditions, he should personally go to the gardening field or base of the seedling sales unit to inspect the seedlings, and then sign the purchase and sale contract and notarize it. It is best to choose those with strong strength, large scale and three guarantees. Fourth, look at the market to attract young people. This is an important factor for successful introduction. Seedling selection should first understand and analyze the market situation, grasp and predict the market well, and select some seedling varieties with many gaps, large demand and good market prospects according to market demand, so as to have market competitiveness and achieve good planting benefits. In recent two years, in order to meet people's growing ornamental requirements, colorful and beautiful saplings such as colorful striped trees, ornamental trees, ornamental shrubs and conifers have been favored by people and have a bright market prospect. These varieties include: Photinia rubra, Ligustrum lucidum, Acer truncatum, Acer truncatum, Abies fargesii, Aralia elata, Sophora japonica and other seedling varieties. Although the price of these seedlings is relatively high, because they have just come out, compared with ordinary seedlings, they give people new horizons, sell well and have great potential for popularization and development. Therefore, it is wise to look at the introduction and promotion of ornamental saplings in the market.
