Pistachio is a kind of leisure Bo dried fruit, it is also known as "no name", "pistachio", is a kind of nuts, bleached shell is white, it is produced in Syria, Iraq, Iran and other countries, our country is only in Xinjiang has planted. Legend has it that in the fifth century B.C., during the Bosnian War, the Persians relied on these pistachios to energize their troops and win battles. When the Persian herdsmen were nomadic, they had to carry enough pistachios to be able to carry out long-distance migratory activities. Pistachio kernels contain vitamin E and other vitamins, which have anti-aging effects and can enhance physical fitness. Ancient Persian kings regarded it as "fruit of immortality". In addition, it also has the effect of laxative detoxification. In addition, the building is mainly to eat if you want to pay attention to, pistachio nuts color green than yellow to fresh. Storage time is too long pistachios should not be eaten again. As a rare delicacy, pistachios were the favorite food of the Queen of Sheba. The Queen of Sheba decreed that all pistachios produced in the territories she ruled belonged to her and the royal family. The royal nuts were imported by American traders in the 1880s, primarily to serve American citizens of Middle Eastern ancestry. About 50 years later, pistachios became a popular snack and were sold in vending machines. These imported nuts were dyed red, partly to stand out and partly to hide the stains caused by traditional harvesting techniques. The birth of California's pistachio industry followed suit when, in 1929, American botanist William E. Whitehouse spent six months in solitude in Persia (today's Iran), collecting seeds and picking through piles of produce in search of the most outstanding pistachios. He returned to the United States with a burlap pocket full of seeds weighing 20 pounds. The following year, experimental plantings were made in California (whose cool desert-like climate made it an ideal place to grow). Since pistachio trees take seven to ten years to mature, it wasn't until 1950 that the first mature pistachio tree appeared. This variety was called Kerman, after the famous carpet-making city near which the pistachio seeds were collected. Since then, scientists have further strengthened the Kerman by budding this variety with stronger primary rooted varieties. The idea of establishing a California pistachio industry is now coming to fruition. Rumors circulated about this new crop, and in the 1960s, pistachio cultivation expanded throughout California. However, many of the problematic aspects associated with this new crop remained a mystery to these adventurous Californians. After a long wait of seven to ten years, expecting their investment to pay off, they eventually discovered that pistachios were an alternate-year crop, meaning that one year the fruit was abundant and the next year it withered. But it was through their diligent efforts and tireless dedication that the pistachio industry took shape. The state is now the second largest producer of pistachios in the world. The first 1.5 million pounds of commercial pistachio crop was harvested in 1976 from 4,350 acres. Today, California has more than 96,000 hectares of pistachio acreage and produces 100 times more than the first harvest.
