The main producing area of Guifei jujube is the hilly area of Sichuan, and the temperature is lower than that of the plain. So it can be planted in the north (North China). It is necessary to strengthen management and protection in winter and spring.

1. Soil improvement

Jujube trees have strong adaptability and low requirements for soil and terrain, and can be cultivated in hills, wasteland, Hetao and flat land. But for the soil with poor site conditions, soil improvement should be carried out before planting. To establish jujube orchard in sandy land, we can use the method of planting green manure in mixed soil, that is, soil improvement; Planting jujube trees in saline-alkali land can build strip fields and terraces, which is beneficial to drainage, lowering groundwater level and reducing salt content in surface soil.

Dig a planting pit

According to the plan and plant spacing requirements, mark the planting point with measuring rope. Dig a hole with the planting point as the center, and the size of the eight characters is generally 60 ~ 80 cm in diameter and depth. The size of planting holes depends on the soil conditions. Planting holes in fertile land can be smaller, and planting holes with poor soil conditions in mountainous areas can be larger. When digging a hole, put a box on the table and put it on one side of the subsoil. Dense planting garden can choose mechanical digging planting ditch. Advocate digging and planting in autumn and planting in spring.

Step 3 apply base fertilizer

Trim microbial inoculum is applied to each mu, and the fertilizer is mixed with topsoil and then backfilled in the planting hole, which can be used for watering in time, planting in time after sinking, or planting in time and watering after returning the soil.

4. Seedling arrangement

Before planting, the seedlings should be arranged and the roots of the seedlings should be trimmed, especially the slightly thick roots and injured roots, which is beneficial to the formation of callus and easy to produce new roots. In arid orchards in mountainous areas, it is beneficial to survival to advocate planting with soil dipped in roots.

Step 5: Field planting.

The topsoil and organic fertilizer backfilled in the planting hole are steamed bread-shaped. Expand the roots, align them left and right, and fill them back and forth. When the soil reaches 2/3, gently lift the seedlings to make the roots stretch and adhere to the soil, then fill the subsoil, step on the edge until it is flush with the ground, raise the remaining soil around the trunk, and then pour enough water.
