The selection of hawthorn seedlings is suitable for leeward sunny, flat terrain, thick soil layer, loose soil and fertile soil, and irrigation conditions. The seedlings are cultivated, the root system is developed, the lateral roots are numerous, the seedlings grow robustly, and the tissue development is substantial. The seedling rate is high. Seedlings cultivated in low-wet or sticky soils with high groundwater levels, underdeveloped roots, few capillary roots, stunted, easily cause root rot, blight and powdery mildew, and are susceptible to freezing damage in cold places; Seedlings in saline-alkali soil, poor growth of seedlings, prone to yellow leaf disease. In addition, it is necessary to pay attention to the fact that the nursery is not suitable for continuous cropping, and it is necessary to carry out rotation to cultivate and improve the ground force. The whole land should pay attention to deepen the soil, and apply about 5,000 kilograms of decomposed farmyard manure per acre. After turning the fertilizer into the soil, use the scorpion to flatten and pour the water into the soil. When the soil is slightly dry, it can be sown. There are two kinds of planting methods: hoe planting and large ridge planting. It is better to do the north-south direction, the width is 1.2 meters, the length of the dragonfly depends on the ground, the spacing between the dragonflies is 30~40 centimeters, and each row is planted with 3 rows. The row spacing is 30 cm and 20 cm, and each plant can be planted with 150 to 300 plants. Large ridge planting, generally ridge width 60 cm, plant spacing 12 cm, can plant about 10,000 per acre.
