The wild fruit looks like a fish scale only once in two years. Once all over the mountain, it is now 100 yuan per jin.

There is such an ancient poem: "the silence of the empty mountain can hear the sound of pine nuts falling to the ground. I think you are also missing friends and can't sleep." This poem depicts a quiet and beautiful scene in the pine forest, and it also brings out a delicious wild fruit, that is, pine nuts. Many people think that as long as it is a pine tree, it can bear pine nuts, but it is not. Only certain kinds of pine trees will bear pine nuts, such as northeast Korean pine, Yunnan sea pine, Huashan pine, Masson pine and so on. The nuts of other pines are Samara, which split and are blown away by the wind. So the next time you see an empty pine tower in the woods, don't be disappointed, you just picked the wrong pine tree.

Pine pagoda is also a kind of wild fruit, because many pine trees are wild. The pine tower looks like fish scales, and the delicious pine nuts are tightly wrapped in fish scales and take 2 years to mature, so it is rare for pine pagodas to bear fruit only once every two years. I remember that when I was a child, this kind of pine trees were all over the mountain, and the fruit of different pine trees matured every year. After September or October, a large group of people always went to the mountain to pick up the pine pagoda. At that time, there were pine towers everywhere. It was very interesting to see squirrels in the mountains eating pine nuts when picking up pine towers.

Pine nuts were worthless at that time because it was very troublesome to peel them out of the pine tower. First of all, you need to expose the pine tower to the sun, hit the pine nuts with a stick after the crack, and then stir-fry the pine nuts with small torches, which is quite troublesome, so it is not as convenient and quick as eating melon seeds. Later, with the development of society, it became popular to eat nuts, people began to pay attention to the nutritional value of pine nuts, pine nuts have gradually become a rarity, the price is also rising.

However, the main reason is the decrease in the number of pine trees and the high cost of picking pine nuts by hand, so a jin of peeled pine nuts is sold for 100 yuan a jin.

Pine nuts were called "longevity fruit" in ancient China. The medical book "Classic of Materia Medica" evaluates pine nuts in this way: "if the taste is sweet and tonifying blood, the blood gas is sufficient, then the five internal organs are self-moistening, whitening is not hungry", which is highly respected by medical scientists of all dynasties. According to traditional Chinese medicine, pine nuts can replenish deficiency and moisturize the intestines, and regular eating can delay aging. According to modern medical research, pine nuts contain a variety of unsaturated fatty acids needed by the human body, which can enhance brain cell metabolism, strengthen brain and tonify brain, and play a certain role in preventing Alzheimer's disease.

Nowadays, there are many modern tools to help peel and thresh pine nuts, which brings convenience to farmers and allows more people to taste the delicacy of pine nuts as soon as possible. Readers, have you ever eaten pine nuts?
