Cultivation methods and precautions of sand apple

1. Maintenance methods

1. Substrate selection: Sand apple does not have too many strict requirements on the soil and can be planted in many soils. The most suitable areas for cultivation are sunny hillsides and plains with saline-alkali soil.

2. Light management: It likes sunny and warm environment, but it needs to be protected from wind. It is not strict on light requirements, so no special attention is required.

3. Nutrient management: Fertilization should be carried out according to the age of the sand pear tree and the fertility of the soil. Use farmyard manure once every autumn, and it is best to add 2 kg of calcium phosphate to each tree.

4. Water management: When soil moisture is less than 50%, water must be replenished in time. In summer, when there is more rainfall, drainage must be done in time. Water should be maintained five times a year. Irrigation should be carried out in July, August and September according to the precipitation. The saline-alkali land should be loosened after precipitation.

2. Breeding techniques

1. Planting: After planting, the trunk should be at a height of about 0.8m-1m, and the grafting point should be parallel to the ground.

2. Pruning: According to different planting densities, choose different tree shapes. After the trunk is determined in the first year, keep the shaping zone and remove the buds in other places.
