[0006] In recent years, domestic scholars have extensively carried out research on the introduction, domestication and artificial cultivation of Sophora chinensis. However, due to the difficulty in raising seedlings of Sophora chinensis, the seedlings are very vulnerable to aphids after emergence, and it is difficult to survive transplanting seedlings. This tree species has not been widely used in the construction of ecological environment in arid sandy areas

Embodiment 1
[0021] A method for raising seedlings of Saccharia chinensis, including seedbed selection, seedling raising method, tending management and nursery out of Saccharia syringae seedlings, suitable for outdoor and greenhouse seedling cultivation of S.
[0022] 1. Seedling selection and seedbed treatment
[0023] 1.1 Selection of seedling sites
[0024] In line with the principle of adapting measures to local conditions and growing seedlings nearby, choose sandy soil that is close to the afforestation site, has flat terrain, is convenient for transportation, has good drainage in and around the nursery site, does not accumulate internal water, does not flood external water, has water sources or irrigation conditions, and is easy to manage; Choose a sandy soil with a soil organic matter of 0.24%, total nitrogen of 0.03%, and total phosphorus of 0.04%; a pH value of about 7 as a place for seedlings. This is because the sandy soil generally has a loose structure, strong air permeabilit...
