After dinner, the second uncle told Chu Jiaqiang about something, that is, those chestnuts in his house are ripe, and they are ready to be picked and sold tomorrow.

"That's fast! Before you know it, the chestnuts are also ripe. Chen Wu sighed. Chu Shengmin said this, and then remembered that chestnuts are generally ripe in September.

"It's better this year, you don't have to go outside." Chu Jiaqiang also said. Those chestnuts, someone asked about them a long time ago. At the beginning, they said that when the chestnuts were ripe, they informed him that he would come up to buy them, and the price would not make the villagers suffer. There are three families in the village who grow chestnuts, adding up, no less than 30,000 catties today, all of which are good goods, so they are also more popular.

Early the next morning, the second aunt took out some sun-dried olive horns and made porridge for everyone to eat. The people in the house like it, and it has a unique flavor just like using sauerkraut to make porridge.

"This little guy is not big, but he eats a lot!" Tang Liye pointed to the bear and said. At the door, the two giant bears are guarding as always, they have nothing to eat for breakfast, and everyone will take care of the bears.

"It's a little better now, but when I grow up, it's going to be fatal." Chu Jiaqiang glanced at the little bear who drank porridge in a big gulp, and the giant bear outside had a headache.

Professor Wen and Fu Shenglin pretended not to hear Chu Jiaqiang's "complaints", and continued to drink porridge. Xu Hao's cheeks were not so thick, and he blushed in embarrassment. These two bears with great appetites can be regarded as forced to Chu Jiaqiang by their research institute.

The little squirrel didn't go out today either. Prepare to pick chestnuts with you later, it is a master with monkeys! After yesterday's incident, the monkey seems to have not changed much in his temper, no wonder others say that the country is easy to change and difficult to change!

Chu Jiaqiang, Chen Wu and Tang Liye went first with long bamboo poles. Those chestnuts must be knocked down with bamboo poles first, otherwise they will not have the ability of squirrel monkeys, and dare to pick chestnuts with bare hands, but there are thorns on the outside.

"This chestnut is a little bigger than what I used to eat, is it a problem with the environment here?" Tang Liye thought that this was caused by the environment of Chujiazhai.

"The north is smaller than the south, and the species seem to be different." Chu Jiaqiang replied.

Chinese chestnut varieties can be divided into two categories: northern chestnut and southern chestnut: northern chestnut has smaller nuts and waxy flesh. It is suitable for stir-frying, and the famous varieties are bright chestnut, pointed oil chestnut, bright picky chestnut, and mountain. Nishiguri and so on.

The southern chestnut nut is larger, and the flesh is japonica, which is suitable for vegetables. There are nine varieties, Kui chestnut, shallow spiny chestnut and so on. The tree is strong. The root system is well developed and there is mycorrhizal symbiosis. It is more drought-resistant, barren and thin, and is suitable for mountain cultivation. Suitable for acidic soils. Multi-row seeding, can also be grafted and propagated. The wood is dense, hard, and moisture-resistant. Branches, bark and bracts contain tannins, from which tannin gum can be extracted.

"Chestnuts, like jujubes, are one of the earliest fruits planted in China and have a long history." Chu Jiaqiang smiled. Chestnut is native to China, and is one of the five famous fruits in ancient China along with jujube, peach, apricot and plum, and is also a world-famous dried fruit tree species.

At this time. The monkey and the little squirrel were already in the tree. Quickly picking chestnuts covered in thorns. However, the monkey did everything half-heartedly, and soon sat down on the branch and ate it himself. Chestnuts can also be eaten raw, Chu Jiaqiang and others have not eaten this less, they have no choice but to eat! The hospitality of the little squirrel family is hard to resist.

But. It is also good to eat more chestnuts. Chestnuts are dried fruit varieties with a high carbohydrate content, which can provide more heat to the body and can help with fat metabolism. To ensure the supply of basic nutrients for the body, it is known as "hardcore crops" and "woody food". It has the effect of invigorating qi and strengthening the spleen, and thickening the stomach and intestines.

Raw or cooked chestnuts can be used to treat diseases such as weakness of waist and legs, frequent urination, nausea, blood in the stool, chronic lymphadenitis and cervical lymph node tuberculosis, as well as chronic diarrhea caused by spleen and stomach deficiency or long-term marriage infertility caused by kidney deficiency. Use air-dried chestnut shells to burn into charcoal and then grind them into powder, add honey to mix and then wash with water to treat internal hemorrhoids.

Some traditional Chinese medicine practitioners also use chestnut shells to treat acute cervical lymphadenitis and goiter in combination with prunella vulgaris and salvia. Its tonic function on the human body is comparable to ginseng, astragalus, angelica, etc.

Soon, others came over and they were behind to help pick it up. The giant bear also followed, and it was estimated that Zhou Furong called over to help carry the chestnuts.

"Be careful! Don't come over here, it's no joke to hit someone. Chen Wu shouted to those people.

"These chestnut skins are so annoying! Deliberately growing so many thorns is scary. Xu Bimei was accidentally stung on her finger, so she didn't have a good impression of the hedgehog-like chestnut skin.

"Don't underestimate this skin! But it has a big effect. Zhou Furong said immediately.

The others looked sideways, not understanding what this layer of skin was for. Zhou Furong told everyone: "Chestnut skin is one of the raw materials for plant color dyes: chestnut skin is the prickly layer wrapped around the chestnut, the layer that is pricked. Chestnut skin is not to be taken lightly, it can be very useful. The ivory white color in antique carpets, and the chestnut skin needs to be used for dyeing and dyeing antique carpets. ”

The skin of the chestnuts used for dyeing must be peeled off after ripeness, and the outer skin must be crushed, boiled in boiling water, and the white wool yarn is put in, and the processing time is determined according to the shade of the desired color. The color of ivory white should not be too long, and after a long time, the color will become very dark and not transparent. Antique carpets are mostly ivory and dyed with chestnut skin.

The two orchids, three orchids, red, wood red and other colors in Xu's carpet are boiled with chestnut skin water after the color is sufficient, and the color will be much softer and not so bright.

"You're going to have to hammer them apart when you go back, right?" Wu Li said while holding a chestnut that had no cracks at all.

"It's also skillful." The second uncle said to him with a smile. Then use your hand to pinch the center point of the concave surface of the chestnut horizontally with your thumb, and there will be a small opening on it, and the two hands will press up and down on both sides of the mouth, and the shell will open up some.

In addition, to remove the hard skin inside, you can put the peeled chestnuts into this bowl, pour boiling water and salt, cover and simmer for 5 minutes, and the skin will be peeled after opening.

Chu Shengmin didn't understand this principle, so he knew that it was the best way to do it. In fact, there is a fibrous connection between the kernel and the peel of chestnuts, and the gap in the middle is very small, and only ionic substances can enter, separating them. While the ionic substances in the water are very small, the salt is completely soluble in water, and its constituent components sodium and chloride ions can enter the kernel and the pulp to separate them.

"Let's fry chestnuts when we go back today." Liang Yu suggested.

"It's not difficult, it's very simple to fry chestnuts in sugar, go back and make them for you." The second aunt immediately agreed with a smile.
