Can sugar oranges be planted in the north?

Sugar tangerine can not be planted in the north, because the climatic conditions in the north are not suitable for planting sugar orange, sugar orange should grow in places with warm climate and sufficient light, and the leaves of sugar orange will be frozen if the temperature is too low. lack of light will affect the sweetness of sugar orange, and the annual sunshine should be guaranteed for 1200-2200 hours to ensure the yield and quality of sugar orange.

Sugar orange can not be planted in the north, and the suitable temperature for the growth and development of sugar orange is 12.5-37 ℃. If the temperature is too low, sugar orange will suffer frostbite. When the temperature is minus 4 ℃, the branches and trunks of sugar orange will be frostbitten. When the temperature is minus 5 ℃, the big branches and branches of sugar orange will be frostbitten, and when the temperature is minus 6.5 ℃, sugar orange will freeze to death.

When sugar orange differentiates flower buds in autumn, the daytime temperature is about 20 ℃, and the best temperature at night is about 10 ℃. The soil temperature needed for root growth is basically the same as that of the upper ground.

Conditions for planting Sugar Orange

1. Temperature, light

The suitable temperature for the growth and development of sugar orange is about 12.5-37 ℃. Too high or too low temperature will affect the growth of sugar orange. When the air temperature and soil temperature are higher than 37 ℃, the fruit and root system of sugar orange will stop growing.

Temperature has a certain effect on the quality of fruit, with the increase of temperature, the sugar content and soluble solids of sugar orange will increase, and the quality of sugar orange will be improved.

Although sugar orange has strong negative tolerance, in order to ensure the yield, it is best to ensure that the annual sunshine is about 1200-2200 hours.

For example, in South China, where the temperature is high and the light is sufficient, the sugar content of sugar orange will be higher, while in Chongqing, where the light is less, the acid content of sugar orange fruit is higher, affecting the quality and taste.

2. Soil

Sugar orange is not very demanding for soil, generally purple soil, red and yellow soil, beach or sea soil can be planted, the PH value in the soil is controlled between 4.2-8, they can grow, the most suitable PH value is 5.5-6.5.

The root growth of sugar orange has relatively high requirements for oxygen content in the soil, and it is best to choose the soil with loose soil, good structure and good drainage performance, and the content of organic matter in the soil should be 2-3%.

3. Moisture

Sugar tangerine will grow better in tropical and subtropical areas where the annual precipitation is about 1000 mm. If the precipitation is uneven or insufficient, timely irrigation is needed to ensure adequate water.

The relative water content of the soil for planting sugar orange is best controlled at about 60-80%, and irrigation is needed if the water content is less than 60%. If Rain Water is too much, it causes stagnant water in the soil, or the groundwater level in the planting park is high, and the drainage performance is relatively poor. It will cause sugar orange tree root death, and the air humidity of sugar orange planting should be controlled at about 75%.
