1, land selection and landscape construction. The growth of blood orange has certain requirements for planting conditions such as nutrients and light. Adequate light can shorten the growth cycle of blood orange, improve the photosynthesis of fruit trees and promote the absorption of nutrients. Therefore, it is best to choose the slightly acidic soil with fertile soil, loose and deep soil and sufficient sunshine as the orchard planting place of blood orange. At the same time, the orchard planting area should be built from a place with flat terrain, close to water sources and convenient transportation, so as to facilitate irrigation and drainage during planting and facilitate fruit transportation. Generally, before planting, proper tillage and weeding should be carried out in the planting area, and orchard planting should be planned while loosening the soil to facilitate planting.

2. Transplanting finished seedlings. When transplanting blood orange, you can buy excellent blood orange seedlings suitable for planting in the market, or you can sow and cultivate blood orange seedlings by yourself. Generally, the suitable time for transplanting blood orange seedlings is February and March in spring or September and 1 1 month in autumn. According to the suitable density, dig out planting holes 80-90 cm long, wide and deep in the planting area, apply enough organic fertilizer as base fertilizer in the planting holes, and then backfill half of the soil before planting.

3. Planting management. In a flat orchard, planting holes can be dug according to the row spacing of four meters and the plant spacing of three meters, so that 45 to 60 seedlings can be planted per mu. If the terrain is slightly steep, the planting density can be appropriately increased. When planting, the roots of seedlings need to be trimmed properly. When placed in the planting hole, try to ensure that the roots are stretched to facilitate planting. When filling the soil, the fruit tree can be lifted gently, so that the roots of the fruit tree can be stretched. After planting, cover the soil, step on it and water it.

4. Fertilizer and water management. In the process of blood orange planting, it is essential to irrigate with abundant water. Fertilization of blood orange fruit trees is mainly based on organic fertilizer, and inorganic fertilizer can be applied appropriately. Different fruit trees use different fertilizers in their growing period, but when applying fertilizer, they mainly apply soil fertilizer or spray foliar fertilizer. Blood orange fertilization is mainly based on nitrogen fertilizer, which is generally applied before and after the growth of fruit trees. Generally, one kilogram of nitrogen fertilizer can be applied to each plant at a time, and a small amount of phosphorus and potassium fertilizer can be used at the same time. Fertilization of adult fruit trees is mainly carried out in the germination, fruiting, expansion period and after fruit picking. Fertilization is mainly based on organic fertilizer. In addition to the need to apply a lot of fertilizer after fruit picking, only a small amount of compound fertilizer needs to be applied several times. Pay attention to timely watering when planting.
