Hemp is one of the ancient crops in China, is one of the earliest grains, because hemp seeds can satisfy hunger, so it was once listed as a grain grain, but since the Yellow Emperor period, it has been withdrawn from the field of food as a staple food, but until later generations in various sacrificial and funeral ceremonies, it can still be seen.

Hemp is mainly used to spin and weave agricultural products, hemp fiber is bonded into a piece by gum, and the gum must be removed when making, so that the fiber is separated, called degumming.

Ramie and flax can be separated into single fibers, the cell wall is not lignified, and can be kept soft for a long time, the thickness and length of the fiber are similar to cotton, and it is the longest of the plant fibers, which can be used as textile raw materials.

The rope grass used by the Tianlong tribe now has too coarse fibers and is harder, far less than the ramie found now, its seeds and hemp seeds, which can be eaten, slightly smaller than mung beans, and the yield is not high.

Hemp seeds are mainly used to extract oil, the oil color is light green, much like filtered rapeseed oil, is a good source of edible oil, its stem bark, after soaking and steaming can extract plant fiber.

Ramie is a perennial root herbaceous plant, you can also use hemp seeds to raise seedlings, our country grows basically white-leaved ramie, used to spin and weave cloth is mainly to use its stem to peel the stem bark, and the bast taken out is called raw hemp or raw ramie.

By soaking and steaming to remove the gum on the raw ramie, the textile fiber that can enter the textile processing is obtained, which is customarily called fine dry hemp in the industry, that is, hemp fiber for textile.

The ramie of the root can generally be harvested 3 times a year, the first growth period is about 90 days, called "head hemp", the second growth period is about 50 days, called "two hemp", the third growth period is about 70 days, called "three hemp", in any position, generally can only harvest one season in the north, it is already a high-yield crop.

Speaking of hemp, modern people are relatively unfamiliar, but if you mention another kind of mental addiction drug - marijuana, it is like thunder.

Marijuana is only one of the hemp crops, the history of smoking marijuana, it is from the Neolithic Age where Wang Tian is now located, the use of marijuana in history is the most famous in ancient India Sango, marijuana is a religious worship in India, similar to the totem of the Tianlong tribe.

Looking at this small piece of ramie that appeared in front of him, Wang Wangtian naturally couldn't help but be overjoyed by this unexpected surprise, which can be used as oil crops, grain crops, and textile crops.

Although the yield of hemp seeds is not high, but the primitive era is now wide and sparsely populated, if you do not consider the yield of raw hemp, the way of slash-and-burn cultivation is adopted, planting a large area, this yield is also gratifying, anyway, it is slash-and-burn farming, and you don't need to worry too much about it to have a harvest, without considering the use of land, it is simply the same as picking it up in vain.

Hemp seeds can be used as food, but the yield is not high compared with other crops, so the best use is to use hemp seeds to squeeze oil, with this vegetable oil, used to cook can be many times better than fish oil, in the tribe Wang Tian used pork anointment oil when cooking, fish oil is only used as lighting, use.

The most important thing is the bark of the hemp, which is steamed to extract the plant fibers, with which they can be used to make fishing nets that are lighter and more durable.

The hemp rope is better than the grass rope used by the Tianlong tribe now, and the fishing net woven with hemp rope can achieve a smaller volume and weight, and it can also make a larger fishing net to fish in the long water.

As for Mai, because of its poor cold protection effect, it cannot replace the status of animal skin, but it can be used in the other three seasons except winter, which has a self-evident effect on establishing ethical concepts and improving the degree of human evolution.

Today's human beings, except for the winter will be wrapped in animal skins, the rest of the time is a small leather skirt, which makes the primitive people's physique exceptionally strong, but the impact of spring and autumn on the human body has greatly reduced the life span of human beings.

With Mai, this situation will be improved, and when humans get used to the usual state of dressing, a sense of shame will arise.

It is said that wearing clothes like a person, isn't this a big step forward for civilization?

Wang Tian asked everyone to stop and carefully collect the seeds of ramie, not a single one of them could be spared, and only after the seeds were collected did they start to let the second brother and Slender Toutuo harvest the plants.

Finally, the roots of ramie were excavated for transplantation and planting, but considering whether they could survive and the difficulty of raising seedlings with seeds, Wang Tian asked everyone to dig only half of the roots.

Except for the seeds, the others remained in place, Wang Tian planned to retrieve the tribe on the return trip, the reason why he was digging now, Wang Tian was worried that it had begun to snow when he returned, so he could take it and leave, and it would not delay time.

Because of the reason for collecting ramie, more than an hour has passed, and the time for lunch has arrived, so Wang Tian decided to go to the bamboo forest to solve the meal first, but ask everyone not to go deep into the bamboo forest, just bury the pot at the edge to make rice.

The little giant panda is cute, but the terrible combat power of the adult panda, Wang Tian decided not to touch the tiger's buttocks, unless it is on the edge of this bamboo forest, you can "pick up" one, so Wang Tian is not against taking one, he came to the bamboo forest in fact just to see if there are giant pandas in the world now.

Coming to the edge of the bamboo forest, Wang Tian began to mark various parts of the bamboo root with a bamboo sword, and then asked everyone to dig according to the mark, Wang Tian was pointing out the location of the winter bamboo shoots for everyone.

Excavating winter bamboo shoots is also a technical job, mainly relying on the direction of the bamboo whip to judge, which part may have winter bamboo shoots, and the experienced old farmers in later generations are almost a digging.

Although Wang Tian has not yet reached that level, there is still no problem with seven or eight out of ten, and the reason why he has this trick is related to his childhood.

Wang Tian grew up in a combination of urban and rural areas in his childhood, and he did not do any less things such as digging bird eggs from trees and going down to the river to fish and turtles, and he did not go to see the excavation of winter bamboo shoots with his friends during the winter vacation.

When he was a child, he had a sweet mouth and was very interested in everything, and the people in the countryside were all very simple and answered all questions, so he also learned seven, seven, eight, eight.

Everyone in the place pointed out by the Son of Heaven, basically can also be planed accurately, which aroused the interest of the giant salamander, at the beginning of the Son of Heaven let the pit be dug, everyone thought that they had found something good, but in the end they found that the Son of Heaven was holding a section of underground bamboo drooling.

Everyone looked at the expression of the Son of Heaven as a foodie, and they didn't need him to say that they knew that this was something that could be eaten, and they all worked hard, and the giant salamander at this time found that according to the place pointed out by the Son of Heaven, there was a chance that winter bamboo shoots could be dug up, but if others dug indiscriminately, it would be thankless, and it was often a waste of hard work.

So the giant salamander asked curiously and shamelessly: "Son of heaven, why do you point one finger at a time, do you have any skills?" ”

"I sniffed it with my nose, isn't your nose quite smart! Then you take a bamboo shoot and smell it and see if you can sniff out where they are. Wang Tian joked.

As a result, the giant salamander believed that it was true, and sniffed everywhere in 4 weeks, looking at his appearance, Wang Tian was happy in his heart, and finally couldn't help laughing.

The giant salamander didn't realize until this time that the Son of Heaven was teasing him, and he couldn't help but scratch his head helplessly, with a look of grievance.

Play with the sky no longer teases him, and seriously impart the experience he learned from others:

One of the techniques for digging winter bamboo shoots is to look at the conditions of the woodland: from the topography of the bamboo forest, the bamboo woodland facing south or southeast has more winter bamboo shoots and the maturity period is early, Wang Tian estimates that this is related to the sun.

Second, looking at the season of winter bamboo shoots, the experience of bamboo farmers is: "Winter bamboo shoots before the ninth year are rotten in spring, and winter bamboo shoots are clear and clear after the ninth year", that is, only a few of the winter bamboo shoots formed before the winter solstice can be converted into spring bamboo shoots, so you can dig them with confidence.

Most of the winter bamboo shoots formed after the winter solstice can be converted into spring bamboo shoots and unearthed into bamboos, which is ...... You can still dig, but now in the primitive era, there is no need to worry about bamboo, and Wang Tian does not have to worry about the reproduction of bamboo forests at all.

Third, look at the age of the bamboo in the bamboo forest, generally speaking, generally speaking, the bamboo that has been bamboo for 2~3 years, the underground bamboo whip shoot rate is the highest, which can reach more than 8 percent.
