The latest blood orange cultivation techniques tutorial

Blood orange is a new citrus variety in recent years, and its pulp and juice are as red as blood, so it is named blood orange. Its variety has the advantages of large seedless fruit, high yield, and taste has been well received by consumers in the market. So how to grow this kind of citrus? Let's take a look.

1. Choose a place to build a garden

It is appropriate to choose the sunny, deep, loose, fertile and slightly acidic soil as the garden site, the slope of the orchard should be less than 25 degrees, and the orchard should be easily accessible and close to the water source, which is conducive to transportation, drainage and irrigation, water storage and so on. After selecting the garden site, clean up the residual weeds on the ground, cover the soil once, make the soil loose, and then plan the orchard and prepare for planting.

2. Planting

Planting time is generally in September-November or February-March, when planting can buy saplings, now the price of saplings on the market is about 8 yuan, can also cultivate their own seedlings. It can be planted at the density of 3 × 4 meters in flat land, generally planting 50-60 plants per mu, while in the case of stepped terrain, it can also be planted at the density of 2.5 × 3 meters, and about 80 plants can be planted per mu.

The specification of the planting hole is each 80cm of the height and width of the hole, and then the base fertilizer is applied to each hole and half of it is backfilled before planting. When planting, trim the root system of the seedling slightly, put it in the middle of the planting hole, stretch the root system, don't twist it together, straighten it up, and gently lift the seedling while filling the soil, so that the root system and the soil can be closely connected, and the soil can be covered with enough water after stepping on the soil. straw can be covered near the root system to moisturize.

3. Fertilizer and water management

In order to meet the growth demand of blood orange, the supply of fertilizer is essential. It is suggested that more organic fertilizer should be applied, inorganic fertilizer should be reasonably matched, and fertilization should be carried out according to the growth status of the plant, mainly in soil and supplemented by foliar spraying. When young trees are mainly nitrogen fertilizer, in the year of planting, it is necessary to apply fertilizer 5-6 times before and after the shoot, each plant can be applied 100-400 grams of nitrogen fertilizer, as well as a small amount of phosphorus and potassium fertilizer. On the other hand, adult trees should apply sprouting fertilizer, fruit protection fertilizer, strong fruit fertilizer and fruit picking fertilizer. 2-4 jin compound fertilizer should be applied to each plant in the first three times, and 50-100 jin organic fertilizer and 1-2 jin chemical fertilizer should be applied to each plant to improve yield and quality. Water management is relatively simple, watering when drought, drainage when stagnant water.

4. Diseases and insect pests

Blood orange will suffer from anthracnose, root rot, mites, scale, aphids, longicorn beetles and other diseases and insect pests, which will affect the growth and development, yield and quality of blood orange. Therefore, we must do a good job in pest control when planting, for example, anthracnose can be sprayed with mancozeb, mancozeb and chlorothalonil in spring and summer and before fruit ripening. Insect pests can be killed artificially and controlled by insecticides, such as avermectin, shameidan, cyhalothrin and so on.
