Is the climate in Zunyi, Guizhou suitable for planting apple trees?

The climate in Zunyi, Guizhou is suitable for planting apple trees. Zunyi, Guizhou has a mild climate and moderate rainfall, which is characterized by significant changes in cold and summer and distinct four seasons.

Apples can adapt to most climates. It is the best choice for apple growth between 35-50 degrees north and south latitude. Apples need 1000- 1600 units of heat and 120- 180 days of frost-free weather. Warm during the day and cold at night, and as much light radiation as possible is the premise to ensure good quality. Apples can resist the frost of MINUS 40℃, and if the temperature is between -2.2℃ and -3.3℃ during flowering and fruiting, the yield will be affected. The propagation technique of apple trees is to cultivate saplings with seeds first, and then graft the selected "scions" onto the saplings. After surviving, grow bigger and plant it in the orchard. Orchard soil fertilization should not only pay attention to the types of fertilizer sources, but also pay attention to the period and method of fertilization. In order to improve fruit quality and reduce the occurrence of element deficiency, we should advocate the use of organic fertilizer and farmyard manure. The previous proposal still applies. Cattle and sheep manure and chicken manure are good sources of organic fertilizer. As a common base fertilizer, the fertilization period is generally in autumn.
