What are the environmental requirements for the growth of apricot trees?
Apricot is a perennial deciduous fruit tree with natural growth of more than 10 meters. It has a long life, like light, cold, drought and barren. It has strong adaptability to the external environmental conditions, and the range of suitable cultivation is also very wide. The average annual temperature of the main producing areas is-5: 22 ℃, the annual accumulated temperature above 10 ℃ is 1000-6500 ℃, the annual rainfall is 50-1600mm, the sunshine hours is 18003400 hours, and the frost-free period is 100,350 days. Thus it can be seen that apricot trees can not only blossom and bear fruit in high latitude, cold and arid areas, but also grow and develop in low latitude, warm climate, humid and rainy areas. Apricot trees are more tolerant to salt and alkali. However, apricot trees are very sensitive to water. If the apricot orchard has accumulated water for more than 3 days, it will cause yellow leaves, fallen leaves and dead roots, resulting in the death of the whole plant. Apricot flower organs and young fruits are also sensitive to low temperature and are vulnerable to late frost, resulting in reduced production.
