What latitude is best for apple growth?

The latitude suitable for apple growth is between 35-50 degrees north and south latitude.

Probably in Shaanxi, Gansu and Shanxi provinces of China, in which Shaanxi is the province with the largest apple planting area and the highest output in China, with the planting area of 1 1 10,000 mu, and the output can account for about one quarter of the country and one seventh of the world. Gansu, Sichuan, Tibet, Yunnan and other provinces are also often cultivated, which is suitable for cultivation in hillside terraces, plain mines and loess hilly areas.

Apple needs 1000- 1600 unit heat and 120- 180 days frost-free period. They can grow in warm areas during the day and in cold areas at night. They have strong cold tolerance and can tolerate the low temperature of MINUS 40 degrees. They are sensitive to temperature when flowering and fruiting, and low temperature will reduce the yield. Apples have no requirements for soil.

Breeding mode

The propagation technique of apple trees is generally to raise seedlings with seeds first, and then graft the selected "scion" onto the seedlings. After surviving, grow bigger and plant it in the orchard.

There are two main methods of grafting: socket method, that is, the scion branches are twisted into peeled hollow tubes, cut as required, and then sleeved on the grafted seedlings.

Grafting method: the grafted saplings are decapitated, and the epidermis is cut into a T-shaped opening at their roots with a knife. Then, the hollow tube scion is pruned according to the shape and size of the T-shaped opening, inserted into the opening of the grafted tree, and wrapped.
