How to grow citrus

1. Maintenance methods

1. Temperature: Since its main distribution area is in tropical and subtropical regions, it prefers higher temperatures, generally between 20 and 30 degrees. However, the higher the temperature is not necessarily better. When the temperature exceeds 37 degrees, its growth will basically stop, so special attention must be paid.

2. Sunlight: Citrus has particularly high requirements for light. Whether there are sufficient hours of sunshine has a great impact on the taste of citrus fruits. If there is insufficient sunlight, the citrus fruits will be more sour. Generally speaking, an annual sunshine time of between 1,200 and 2,200 hours is considered pretty good.

3. Watering: Citrus has a relatively high demand for water. Especially in the dry season, special attention should be paid to irrigation. In orchards, strip irrigation can be used.

4. Fertilization: Fertilizer will also have a relatively large impact on the yield of citrus. One month after the seedlings are planted, you should start fertilizing. But the amount of fertilizer applied at one time should not be too much.

2. Breeding techniques

1. Reproduction: Seeding propagation can be adopted. Choosing good quality seeds will also be of great help to the subsequent yield. In addition, when choosing a planting site, you need to pay a little attention to nutrients and whether the drainage is good. It is best to mix in base fertilizer. After sowing, water thoroughly.

2. Pruning: This step plays a relatively important role in the growth process of citrus. Not only will it make the tree shape more beautiful, but it will also increase its fruit yield. In spring, you can pinch the tops appropriately. In addition, when the branches are very dense, some of them need to be thinned out, otherwise it will seriously affect the ventilation and light transmission effects.

3. Problem diagnosis and treatment

1. Disease: There is a disease called "Huanglongbing", which is more likely to occur when the seedlings are young. The diseased plants can be disposed of in time and sprayed with fungicides. In addition, there will also be "ulcer disease", which will cause leaves to fall and branches to dry up. Copper oxychloride can be used for prevention and control.

2. Pests: Types include "red spiders", "leaf miners", "scale insects", etc., which can be controlled by different pesticides.
