The acidity and alkalinity of food is not determined by its taste, but by whether the substances produced after food is digested by human body are alkaline or acidic. Most fruits we eat, except plums, strawberries and lemons, are basically alkaline fruits.

Because eating oranges will have a sour taste, many people think it is acidic food, but it is actually wrong. Because the content of mineral elements such as potassium, calcium and phosphorus in oranges is high, the products after metabolism are alkaline after entering the human body, so from the perspective of nutrition, oranges belong to alkaline food.

A, citrus planting conditions:

1, temperature

Generally, the temperature is required to be between 12℃ and 37℃, and the growth temperature is similar to that on the ground. Especially if the weather temperature is too high or too low, it is not conducive to the growth of citrus.

2. Land

The pH value of the land where oranges are planted is between 4.5 and 8, and the most suitable pH value is between 5.5 and 6.5. When planting, you must choose loose soil, and the soil must be fertile and have high organic matter content. The soil with particularly strong drainage capacity is very suitable for planting orange trees.

3. Lighting equipment

Citrus is a relatively shade-tolerant fruit tree, and the light time can be sufficient. Citrus belongs to a fruit tree that likes warm and wet.

Step 4: Moisture

Citrus needs water and is afraid of it. At ordinary times, it is necessary to ensure the law of water supply, and flooding is not allowed, especially when seasonal precipitation is uneven.
