The planting method of "aristocrat in Orange" Blood Orange

Blood orange, also known as red orange, is a variant of orange, with deep red pulp and juice, sweet and juicy, mostly without fruit core, mainly distributed along the Yangtze River in China. So, what is the cultivation method of blood oranges? Let's find out together!

1. Choosing land to build gardens

For planting blood orange, it is suitable to choose sunny, deep soil layer, loose fertile soil and slightly acidic soil as the garden plot. The slope of orchard should be lower than 25 degrees. In addition, the garden plot should be convenient for transportation and close to water source. This is beneficial to transportation, irrigation and water storage during planting. After selecting the garden plot, clean up the residual weeds on the ground, cover the soil once, loosen the soil, and then plan the orchard and prepare for planting.

2. Planting

The planting time is generally from September to November or February to March. You can buy saplings when planting. At present, the price of saplings on the market is about 8 yuan per plant. You can also cultivate seedlings by yourself. On the flat ground, you can adopt the density of plant spacing of 3×4 meters. Generally, 50-60 plants can be planted per mu. If it is stepped terrain, you can also open holes according to the density of 2.5×3 meters, and about 80 plants can be planted per mu.

The specification of planting holes is 80cm in height and width respectively, and then half of the holes are backfilled after applying base fertilizer. During planting, the roots of seedlings are slightly pruned. In the middle of planting holes, the roots are spread out without twisting together. The seedlings are straightened and gently lifted while filling soil. In this way, the roots can be closely connected with the soil. After covering the soil and stepping on it, they can be watered enough. The roots can be covered with straw to keep moisture.

3. Fertilizer and water management

In order to meet the growth demand of blood orange, the supply of fertilizer is indispensable. It is suggested to apply more organic fertilizer and inorganic fertilizer reasonably. Fertilization should be carried out according to the growth status of the plant. Soil fertilization should be the main fertilizer, foliar spraying fertilizer should be supplemented, nitrogen fertilizer should be the main fertilizer in young trees, 5-6 times should be applied before and after sprouting in the planting year, nitrogen fertilizer 100-400 g and a small amount of phosphorus and potassium fertilizer should be applied to each plant every time. Adult trees should apply germination fertilizer, fruit retaining fertilizer, strong fruit fertilizer and fruit picking fertilizer. 2-4 jin compound fertilizer can be applied to each plant for the first three times, and 50-100 jin organic fertilizer and 1-2 jin chemical fertilizer should be applied to each plant for fruit picking fertilizer to improve yield and quality. Water management is relatively simple. Water can be watered when drought occurs, and drainage can be carried out when accumulated water occurs.

4. Diseases and pests

Blood orange will encounter anthracnose, root rot, mites, scales, aphids, longicorn and other pests and diseases during planting, which will affect the growth, development, yield and quality of blood orange. Therefore, pest control must be done well during planting. For example, anthracnose can be controlled by spraying mancozeb, mancozeb, chlorothalonil and other pesticides at spring and summer tip development stage and before fruit ripening. Pest can be controlled manually and by pesticides. Commonly used pesticides include abamectin, cartap, Cyhalothrin, etc.

The above is a simple introduction to the cultivation method of blood oranges, I hope it can help you!
