1. Cutting of apple seedlings: After the apple seedlings arrive, if it is not the planting season, cutting should be carried out first. Heel in's method: choose the shady place behind the house to dig ditches, generally 40 cm deep and 80 cm wide, depending on the number of apple seedlings. If the soil is dry, fill it with water first, and then dig the ditch when the water is soaked. Cut the apple seedlings to about 10 cm above the fixed dry height, untie the rope that binds the root system of the apple seedlings, and put the apple seedlings at an angle of 45 degrees with the bottom of the ditch. The roots are evenly arranged on the slope in the ditch, and then the exposed apple seedling surface in the ditch is tightly covered with soil. If the roots of apple seedlings lose water, they can be soaked in water for 12- 15 hours and then followed.

Second, the row spacing of apple seedlings: the row spacing of planting plants varies with topography, soil type, tree species and rootstock. Seedlings with poor soil in mountainous areas, wasteland or dwarf rootstocks can be planted slightly densely, and seedlings with fertile soil in plains can be planted thinly, with plant spacing of 2 meters to 3 meters and row spacing of 4 meters to 5 meters.

Third, the preparation of caves and ditches: Generally, the caves of fruit trees are 60-70 cm deep and 60-70 cm in diameter. The size of the planting hole also depends on the soil quality. Dig a small pit if the soil is good, and dig a big pit if the soil is bad. Topsoil and new soil should be placed separately. After mixing the topsoil and the decomposed soil fertilizer evenly, fill it in the lower layer of the apple tree hole, and put the new soil on the surface. The spacing between the root zone and the fertilization zone is 20 cm. It is forbidden to use fresh manure as base fertilizer to avoid damaging roots.

Fourth, seedling planting: planting apple seedlings in spring depends on seedling conditions. If there is water loss, the apple seedlings should be soaked in clear water 1 day and night, so that the apple seedlings can fully absorb water before planting. The planting time is generally 5- 10 days before the initial flowering of local apricot trees, and the planting should be standardized and arranged in rows. The planting depth is usually based on the root neck trace of apple seedlings and the level of the ground. The interface should be on the windward side, and the root system should be extended, then the soil should be cultivated, stabilized and irrigated, and then the pit should be sealed after water seepage, which is convenient for water conservation.

Five, seedling drying: apple seedlings should be dried in time after planting. Apples are mostly trunk trees led by the central government, which need 70-80 cm stems. There should be complete buds in the 20 cm plastic belt cut from the main branch.
