After only one day of rest, on the third day after the return of the expedition team's third expedition, Su Yan and his two hundred tribesmen were busy in the farmland outside their residence.

The area of farmland is about more than 700 acres, last year most areas of the farmland were planted with hemp, hemp seeds and hemp fiber harvest, the yield of hemp seeds per mu is relatively low, hemp seeds are not worthy of Su Yan's attention, the most important thing is hemp fiber, 700 acres of hemp output of hemp fiber dragon tribe can not be used up in a year.

Thanks to the harvest of two acres of millet last year, this year's planting can be used to plant 100 catties, according to the calculation of one pound of seeds planted on one acre, this year's millet planting area can reach 100 acres, and the remaining 600 acres of land is used to plant hemp.

More millet will be harvested this year, millet as the main food of the dragon tribe in the future will continue to expand the planting area, the seven hundred acres of fields outside the dragon tribe's residence are not enough to grow millet, not to mention hemp, last winter Su Yan has made a decision, at the end of the spring, the dragon tribe will continue to open up the wasteland, expand the area of planting land next year.

Moreover, the total population of the Dragon Tribe has made great strides this year, and the adult labor force has increased a lot, and it is expected that there will not be many houses to be built next spring, and Su Yan can mobilize more clansmen to cultivate land.

This year's millet and hemp planting methods are the same as last year's, still holding a sharpened stick at one end and inserting a hole in the soil and then putting crop seeds in the soil, and after one or two years, if the fertility of the land declines, you have to increase farm fertilizer.

For growing crops, ploughing is an important one:

Ploughing the ground can make the soil soft, suitable for the growth of plant roots and nutrient absorption; Ploughing can swap the position of the surface soil and the deep soil, which is conducive to the uniform distribution of soil nutrients. The turned soil is soft and breathable, so the rainwater is easily retained in the soil and the air can enter the soil; When turning the soil, it has a weeding effect, and it can also kill some insects hiding in the soil, so that the seeds sown in it can easily germinate and grow.

Turning over the ground is so important, but it is a very troublesome thing for the dragon tribe, Su Yan knows that the shape of the farm tool can also use wooden sticks and stones to make similar farm tools, but it costs a lot to make a farm tool, and the dragon tribe needs no less than one or two, but hundreds.

The most helpless thing is that the agricultural tools made of wooden sticks and stones are too inefficient compared with metal agricultural tools, and in the most important spring, Su Yan cannot waste so much labor on farming.

However, this situation will change next year and the year after at the latest.

Under the leadership of Su Yan, 200 tribesmen worked together to plant millet in one day, hemp in six days, and the 200 tribesmen who were busy planting turned to the project of building houses, which is still the most important task this spring.

After finishing the farming work, Su Yan went to inspect how the female clansmen weaved linen, and the Xiaohua Xiaoyue sisters also participated in the labor of weaving linen.

Satsuki and the other female clansmen used rudimentary tools to weave pieces of coarse linen cloth, which was too coarse to be used as sacks, and it was impossible to use it to make linen, and the people basically did not wear this kind of linen made of rough linen.

The tribesmen are already familiar with the process of weaving linen, and once they put it into it, they will not stop for half a day, and the possibility of mistakes is very small.

Su Yan felt that they could try to weave linen with finer twine, although weaving linen with finer twine would greatly increase their labor time, but it was a path that the tribe had to walk.

As the population of the tribe grows larger, and as there are fewer and fewer beasts in the jungle, even if the dragon tribe has begun to raise animals on a large scale, it will not be possible for everyone to wear clothes made of animal skins in the future, let alone clothes made of animal skins in the hot summer.

For a short period of time, Mai was undoubtedly the best choice to replace animal skins as clothing, provided that Mai was not so rough, otherwise the tribesmen would rather use plant leaves as clothing than wear rough and uncomfortable Linen.

At present, the linen cloth spun by the dragon tribe is about four to five vertical lines per square centimeter, and the vertical lines and horizontal lines of linen suitable for making clothes should be about ten per square centimeter, and the span is a bit large, but it is acceptable, but the time required to weave linen will be greatly increased, and I don't know when the spinning wheel and loom will be made, and there are no production tools, so it is even more difficult to make a spinning wheel and loom.

At present, all the hemp fibers in the dragon tribe have been kneaded into hemp rope, the third hemp rope is the thinnest hemp rope in the dragon tribe, mainly used to weave fishing nets, the average diameter of the third hemp rope is about 2.5 millimeters, and the diameter of the hemp used to spin out the linen cloth with about ten vertical lines per square centimeter is only about one millimeter.

Su Yan took a few female clansmen to get busy, took a complete large pottery and loaded it with water, and then took a bundle of hemp rope, regardless of the thickness of the hemp rope, put this bundle of hemp rope into the water to soak, after soaking for a period of time, use your hands to separate the hemp fibers gathered into hemp rope, and re-knead the hemp fibers into newer twine.

Su Yan rubbed out a twine about one millimeter in diameter, and used this twine as a standard, and asked several other women to use hemp fibers to make twine of rough specifications.

After harvesting a batch of twine about one millimeter in diameter, Su Yan summoned the women who would weave the linen, including the Xiaohua Xiaoyue sisters, and Su Yan handed the twine to Xiaohua, so that Xiaohua could try to use the finer twine to weave the linen first.

Xiaohua followed Su Yan to learn martial arts, and the flexibility of her body, including her fingers, was naturally not comparable to other clansmen, so Su Yan asked Xiaohua to demonstrate first.

Xiaohua did not have stage fright, took over the twine from Su Yan, the elder brother and husband, skillfully connected the twine finely to two parallel wooden sticks as vertical lines, and then took out a bone needle to tie the twine to the tail of the bone needle as a horizontal line, the bone needle went up and down in the fine vertical line, and then proceeded to the next row after one row, although the twine was thinner, but it did not cause much trouble to Xiaohua.

"Xiaohua, stop and let the others try."

"Okay."

Su Yan casually pointed to someone to replace Xiaohua, and the newly inaugurated clansmen began to weave linen cloth as a matter of course, without any mistakes, but her weaving speed dropped a lot, and the finer twine greatly increased the difficulty of weaving linen.

(Note: There was a relatively big mistake in the previous article, Heng Yi calculated one acre of land as 333 square meters, which should be 666 square meters, which has been fully modified, that is, the area is divided by two, and the harvest is divided by two)
