What are the latest planting requirements for Orah mandarin?

Orah mandarin is a relatively popular citrus variety in recent years, and the economic value it brings can be called a leader in the citrus industry, and many growers have switched to planting Orah mandarin. However, Orah mandarin also has certain requirements for planting conditions. Let's learn about them together below.

1. Temperature requirements

Orah mandarin has moderate cold tolerance and is suitable for planting in production areas with an annual average temperature above 17.5 degrees. The minimum temperature requirement must not be lower than 0 degrees. It is a late-maturing variety and needs to hold too much fruit, so the temperature requirements for the planting site are relatively high. Only when the annual average temperature reaches 20-22 degrees, because only when the temperature is sufficient can the carbohydrates in it accumulate adequately and produce larger fruit and better taste. If the temperature is too low, freezing damage is very likely to occur, the fruit produced will also be relatively few, and the planting benefit will be greatly reduced.

2. Soil requirements

Orah mandarin can be cultivated whether in paddy fields or dry land. If mountain cultivation is chosen, the hillside needs to be below 15 degrees. In addition, Orah mandarin requires a water source nearby and convenient drainage and irrigation. Although it has a certain drought resistance, drought will also affect the expansion of Orah mandarin. At the same time, fertilization also requires the participation of water, so having a water source nearby is very important for Orah mandarin.

3. Rootstock requirements

In production, sweet orange, red tangerine, trifoliate orange, and citrange can be selected as rootstocks. There is grafting incompatibility with citrumelo, so avoid choosing citrumelo as a rootstock. In areas with high heat, vigorous rootstocks such as Volkamer lemon and rough lemon can be selected to avoid the fruit acidity being too low and making the flavor bland.

4. Fertilizer and water requirements

Orah mandarin has strong growth vigor and the fruit hangs on the tree for a long time, so it has a relatively large demand for fertilizer. In production, basal fertilizer should be applied heavily, and the basal fertilizer should mainly be decomposed and fermented farmyard manure or compound fertilizer. When planting on barren soil, soil improvement should be strengthened, more organic fertilizer and phosphorus and potassium fertilizer should be applied, and zinc and magnesium fertilizer should be maintained in an appropriate amount to keep the leaves dark green.

5. Management requirements

Orah mandarin has strong high-yield performance, relatively little fruit drop in winter, excellent fruit-bearing performance, and a long fruit harvesting period. In order to avoid small fruit and alternate bearing, in production, fruit should be thinned in time according to the tree load and harvested at the proper time.
