Pistachio is a kind of leisure dried fruit, also known as "Wumingzi" and "Pistachio", which is a kind of nut with bleached shell. Produced in Syria, Iraq, Iran and other countries, only Xinjiang is cultivated in China.

Pistachio nuts are the fruits of happy fruit trees. Xinkai fruit tree is the fruit of nameless deciduous trees in Lacqueraceae. It is a long-lived tree with a height of 10 meter and a tree age of 300 ~ 400 years. It blooms in May and bears fruit in September every year. Pistacia vera is a kind of dried fruit, commonly known as pistachio, also known as "nameless seed", which is similar to Ginkgo biloba, but different from cracked and cracked Ginkgo biloba.

Pistacia vera belongs to Lacqueraceae, with about 20 species, which are divided into two categories: Central Asia Group and Mediterranean Group. This species was published by Swedish botanist Linnaeus in his book Flora 1753.

Is pistachio a hair care product?

1, long growth cycle: At present, the market is mainly divided into four price ladders according to the quality of pistachios, which is also the result of the unique long growth cycle of pistachios. It takes 14 years for a happy fruit tree to enter the fruiting period, and it takes 6 years for a seedling to grow into a trunk, so it is not unreasonable to say that things are rare.

2. Small planting area: Due to the special growth cycle and environment of Pistacia vera, there are few areas where Pistacia vera can be planted in China, which are basically concentrated in Tianshan area of Xinjiang, and the planting in other places is sporadic, so the planting area of Pistacia vera is very small, the natural output is negligible, and the price is also rising.

3. Import: The conditions for the growth and development of pistachios are dry and hot places, so as to ensure that pistachios are not affected by moisture and mildew. Basically, the original planting areas of pistachios are in the arid areas of West Asia or the vast plains of the United States. Therefore, most pistachios in China are imported, so it is natural that they are expensive.
