American almond is hailed as the king of dried fruits in the world.

The commercial name of American almond is American large almond. It is a world-class superior dried fruit tree species, and its yield and trade volume rank first among the world's six major dried fruits (chestnut ranks fifth). The edible part of the almond is the kernel, which is sweet, fragrant, crisp, and can be eaten directly. It is also a premium oil material. Almond oil is a premium health-care edible oil with good physicochemical properties, does not easily deteriorate during long-term storage, and is easy to digest and absorb after consumption. It has anti-cancer and cancer-preventive effects and is used to treat diabetes, epilepsy, and stomach diseases. Almond oil is also the most suitable skin moisturizing oil, massage oil, and sunscreen oil. Japanese original imported almond oil, each bottle 60 ml, priced at 750 yuan. The annual output of almond kernels in China is 450 tons, and more than 1,500 tons of almond kernels are imported from the United States each year; in years with high imports, the amount exceeds 6,000 tons. American almond has three advantages over wild apricot: first, its flowering period is later than that of wild apricot, which can avoid or reduce late frost damage; second, its shell is as thin as paper, and its kernel yield and production are both more than 50% higher than those of wild apricot; third, it sells well in countries around the world, while the domestic market is short of supply, and its selling price is 2-3 times higher than that of wild apricot kernels. American almond is mainly distributed within the range of 30-45 degrees north latitude, and has the characteristics of liking light and avoiding shade, disease resistance, cold resistance, drought resistance, tolerance to barren soil, fast growth, high yield, and high quality. American almond has a well-developed root system with xerophytic structures and strong drought resistance; it can grow even in areas with annual rainfall of only 39-58 mm. Annual rainfall of 400-450 mm is most suitable. Its cold resistance is also strong, and during dormancy it can endure low temperatures of -22°C to -33°C. It can tolerate high temperatures and grows well in areas with temperatures of 36-40.5°C. Under good conditions, the yield per mu can reach 150-300 kg, and the income per mu can reach several thousand yuan, or even more than 10,000 yuan. From this it can be seen that American almond is a pioneer tree species for dry, barren mountain land, the best choice for returning farmland to forest, and an excellent soil and water conservation tree species for China's arid Northwest and North China regions. It will produce major benefits in comprehensive small watershed management and the construction of ecological agriculture. It is also an economic forest tree species with great development prospects. Developing almond production according to local conditions is an important way for farmers to become wealthy. American almond also has strong ornamental value and is an economically beneficial landscaping tree species, and it is bound to occupy a place in urban greening and beautification. American almond has a lifespan of more than 120 years, so it can truly be said that planting the tree for one year brings benefits for a hundred years.
