Citrus Growing Techniques How citrus needs to be grown

Citrus seedlings can be grafted when planting, choose a lot with fertile soil and good drainage to plant citrus trees, dig a deep pit when planting, fill it with compound fertilizer and topsoil, and water it after the land. In the process of growth, the branches and leaves should be pruned in time, the branches and leaves that are weak and weak and the local dense branches and leaves should be cut off, and the soil should be turned over often to increase the air permeability of the soil, and fertilization should be carried out according to different growth stages. Next, let's take a look at the planting technology and management of citrus.

1. Planting technology.

1.Grafting seedlings.

You can use the single bud ventral grafting method, paste the scion on the rootstock, wrap it with plastic film, and cut the anvil twice after the grafted seedlings survive, and then cut the anvil twice when the spring germination and hair extraction.

2.Planting in the garden.

To grow citrus, choose a site with fertile soil and good drainage, as well as easy irrigation. Properly carry out land preparation, dig out a tree pit with a length and width of about meters and a depth of about meters when planting, fill it with base fertilizer such as compound fertilizer, mix topsoil, and water thoroughly after putting in seedlings.

2. Management technology.

1.Soil management.

The soil in which citrus is grown should be breathable and deep, so that the citrus roots can grow better. Citrus planting in low-lying plots should be avoided and the plots should be turned down regularly to remove weeds and increase soil permeability and drainage, preventing soil compaction. In the process of deep ploughing, organic fertilizer can also be applied to improve the soil, which plays a good role in promoting the growth of citrus.

2.Pruning and leaf pruning.

For young trees, pruning is sufficient, and dry and pest-infested branches should be cut off. Usually in spring and autumn, it is necessary to prune weak branches, dense overlapping branches, which helps to improve the light transmittance of the whole plant. Proper topping in summer to save nutrients for trees.

3.Water and fertilizer management.

Frequent turning of the soil can increase the permeability of the soil, and removing weeds can save nutrients. Before budding in spring, you can apply human manure, cake fertilizer, pig manure, etc. In July, nitrogen, phosphorus and potassium fertilizers are mainly applied, and post-harvest fertilizers are applied in October-November, usually citrus trees can be fertilized 3-4 times a year, and microbial fertilizers are appropriately used to decompose the substances in the soil.

Proper watering after each fertilization application can promote nutrient absorption. Fertilizer can be microbial fertilizer, which can decompose toxic substances in the soil.

4.Pest and disease control.

During the planting process, the orchard should be controlled with pests and diseases, canker, anthracnose, red spiders, etc. are common pests and diseases. Pesticides can be used for full-crown spraying to spray pests and diseases; Physical methods such as the use of violet lights and sticky insect boards can be used for trapping insect infestations. Prune the diseased branches of fruit trees, and clear the garden in winter to prevent disease overwintering and protect the growth of citrus in the coming year.

1. Soil conditions: When planting citrus, you need to choose soil rich in organic matter. 2. Planting method:

The citrus seedlings are transplanted into the soil each spring and watered with rooting water. 3. Watering management: When the environment is dry, water should be poured into the roots of citrus.

4. Thinning flowers and fruits: cut off the flower buds that grow too much in citrus to improve the fruit setting rate of the plant.

1. Soil conditions

Citrus is suitable for growing in the soil with deep soil layer and good drainage, when planting citrus, it is necessary to choose soil with rich organic matter and pH less than 8, and to apply well-rotted organic fertilizer, superphosphate, etc. to the soil, which is conducive to the vigorous growth of citrus.

2. Planting method:

The best time to plant citrus is in March and April every spring, because this is the germination period of the plant, which can improve its survival rate, you can plant the citrus seedlings into the soil, and then water them again, so that the citrus seedlings and the soil are closely gathered to maintain the normal growth of citrus.

3. Watering management

Citrus is not drought tolerant, when cultivating citrus, if the environment is too dry, it will cause the branches and leaves of the plant to dry out, and will affect the yield of citrus, you need to water the citrus when there is no rain, you can directly water the water to the roots of the plant, so that it can be quickly absorbed.

4. Thinning flowers and fruits

When cultivating citrus, it is necessary to cut off the flower buds that grow too much after the plant blooms, so that the nutrients of the citrus are concentrated to the fruiting branches, and after the citrus bears fruit, it is necessary to remove the deformed and overgrown fruits, so as not to lose excess nutrients and increase the yield of citrus.

The planting of citrus is not difficult, the key is to formulate a scientific and reasonable planting plan according to the growth needs of citrus, grasp the correct planting method, and introduce some technical points about citrus planting to you.

1. Reasonable selection of orchard soil and fruit tree varieties.

Citrus growth is directly influenced by the soil of the citrus orchard and the varieties of fruit trees. Therefore, orchard soil and fruit varieties should be reasonably selected. In general, citrus plantations need fertile soil, no pollution, away from cities, plenty of sunshine, and a pleasant climate.

The soil fertility is sufficient, the fertility is uniform, the pH is moderate, and the organic matter content meets the needs of citrus growth. Fruit tree varieties should have strong branching ability and high germination rate.

2. Scientific fertilization.

Nutrition is the foundation of citrus tree growth. Only through scientific fertilization can the yield and quality of citrus be improved. In general, fertilization should be carried out in the following stages.

In the first stage, 7 days after the citrus is picked, fertilization is applied, using specialized fertilizer and rotting chicken manure. In the process of applying basal fertilizer, the depth of the planting furrow should be strictly controlled, and the fertilization direction should be scientifically adjusted according to the standard of 20 to 40 cm.

In the second stage, fertilization takes place during citrus planting. The microbial fertilizer selected needs to contain anaerobic bacteria and aerobic bacteria to promote the decomposition of harmful substances in the soil, minimize the residue of chemical fertilizers and pesticides in the soil, and meet the demand for organic fertilizer for citrus growth.

Top dressing twice a year, the first time in the spring. When the temperature is above 23, apply urea and microbial fertilizer, add an appropriate amount of water, let it stand for two or three days, and spray the mixed fertilizer on the canopy of citrus trees. Fertilization is applied twice a year in June. Apply the same fertilizer for the first time and spray near the citrus drip line.

The fourth stage of fertilization is carried out during the spring growth of the trees, spraying trace elements on the leaves.

3. Prune at the right time.

Pruning can also affect fruit quality and citrus yield, which can effectively reduce the occurrence of pests and diseases. Generally, the trunk height of young citrus trees is controlled according to the standard of 25 to 40 cm, and the total amount of main branches and compound branches is according to the main branches.

Three, four, lateral main branches.

Five, six standard control. Through scientific plastic pruning, the branches swell and the crown grows into a round head. After the citrus tree grows, it should be pruned again in the summer, otherwise the fruit will be reduced due to the influence of the trunk.

Prune the main branches of citrus in the spring and fall to remove overlapping branches and diseased branches. If the branches are too dense, prune the main branches to meet the light needs of citrus growth. At the same time, the necessary pruning is carried out on vegetative branches and fruit branches, and the ratio of leaves and fruits is strictly controlled.

Fourth, scientific intercropping and pest control.

Combined with citrus varieties and growth characteristics, reasonable control of planting density and improvement of photosynthetic efficiency can increase citrus yield. It is suitable for intercropping, and avoids problems such as low roots and shallow roots. Legumes are the best plants for citrus intercropping.

The soil needs to be buried, and the tree trays need to be completely covered. Broccoli, for example, can be planted appropriately in autumn and buried in the garden the following year to effectively increase soil fertility. In addition, pests and diseases can adversely affect the normal growth and fruit bearing of fruit trees.

Therefore, it is necessary to adopt corresponding control techniques in combination with common citrus pests and diseases to minimize the adverse effects of pests and diseases.

We must ensure the fertility of the soil, but also pay attention to the density of planting, in the process of planting management, we must water and fertilize in time, but also do a good job in preventing pests and diseases, but also master the basic theoretical knowledge, and then we should also choose healthy and full seeds.

First of all, we should choose some high-quality varieties, and then we should also keep enough light, carry out sufficient photosynthesis, spray pesticides regularly, loosen the soil in time, maintain the permeability of the soil, do a good job in the drainage contract, and also need to prune some residual branches to avoid rotting.

Soil selection, variety selection, scientific fertilization, timely pruning, and pest control.

The soil should be buried, the height of the trunk should be controlled at about 25 30 cm, and the fertilization time is generally 7 days after the citrus is picked.
