The jujube planted in the autumn is strict with six levels
Good seedlings: Avoid root damage when lifting. In order to facilitate planting, the main root can be trimmed slightly after lifting to facilitate the water absorption of seedlings and increase the survival rate. When the seedlings are shipped, 50 to 100 trees should be tied into a bundle, wrapped in plastic film and then transported. Dig a tree pit: Dig a tree pit 50 to 60 cm square so that the roots of the seedlings are fully stretched in the pit. When digging, separate topsoil and subsoil, and then fill the topsoil with the bottom of the pit. Apply base fertilizer: When digging a tree pit, apply 5 kg of high-quality organic fertilizer to the bottom of the tree. You can also use 20 kg of organic fertilizer mixed into the pit when the soil is excavated. Seedling root dipping: Before planting seedlings, the roots of the seedlings were immersed in a phosphate fertilizer plus root powder solution for 20 minutes or the phosphorus fertilizer solution was immediately planted. The roots of the seedlings not only healed quickly but also were easily rooted. Standardized planting: The seedlings are planted in the center of the tree pit, and the depth of the buried soil is 3 to 5 cm deeper than the original soil marks when the seedlings grow in the nursery. When planting, the seedlings should be shaken while filling in order to fully extend the root system and make close contact with the soil. After the seedling roots are fixed, they should step on solid soil, pour enough water, make a good tree tray, and cultivate a round pile, so as to facilitate wind protection and protection. Tree disc coating: In the jujube tree tray has been planted with a plastic film covering the tree plate, so that it can not only protect the grasshopper, but also protect against cold, make the seedlings safe winter, jujube seedling survival rate is high.
