Three Kingdoms: I help Liu Bei grow thousands of miles

Chapter 668

Longchuan is located in the northeast of Jiaozhou. Because it is the farthest from the political center of the South China Sea, and also far from the seaside of Jieyang, it has the smallest population and the weakest economic strength among the six counties in the South China Sea.

After several years of management in Tandingzhou, it finally attracted a large number of immigrants to move in, and became the second most populous county in the South China Sea after Guangzhou (including Panyu).

Gan Ning's messenger arrived in Longchuan, and Tan Dingzhou personally took him to Jieyang.

Jieyang is adjacent to the sea and has an inland river. The land is fertile and open. Most of the aborigines are fishermen. The farmers who grow food are relatively backward in planting technology.

After Tanding Zhou became the governor of Longjie, he approached Lantian to apply for several agricultural researchers, and under their guidance, production was improved.

When Shamoke was stationed in Longchuan, he established friendship with the two "minorities" of Tan Dingzhou, and settled the barbarians who moved from Chenyang in Jieyang, where they continued to make a living by fishing and growing rice.

After Lantian proposed artificial planting of kelp, he took dozens of agricultural researchers and craftsmen to Jieyang half a year ago.

The principle of kelp farming is indeed simple, coupled with the experience of later generations of kelp farmers, it is enough to choose the safest and firmest single raft for rope farming.

Lan Tian once dabbled in the cultivation of kelp in the elective course of agriculture, so there is no technical obstacle, but the production tools are extremely backward in this era, and the first step has become a big problem, which is to raise seedlings with wild kelp.

In the process of kelp cultivation, seedling cultivation requires the most energy, which is why Lantian stayed in Jieyang for half a year.

Kelp seedlings are the first to build a nursery. The nursery needs to consider complex processes such as water source and temperature control. The water supply and drainage system does not have the support of a water pump. The siphon technology is completed.

The water supply and drainage system of the nursery field covers siphon rooms, sedimentation tanks, filter tanks, cooling tanks, water storage tanks, return water tanks, water supply tanks, etc., without modern industrial equipment, it is all done by manpower.

Fortunately, what Lantian lacks most now is people. Dozens of craftsmen are responsible for controlling the craftsmanship, and thousands of barbarians in Shamoke mainly do physical work. They are more enthusiastic about finding a livelihood for the clansmen than building Guangzhou City. In conjunction with the construction of the nursery, even the living houses of agricultural researchers and craftsmen were built.

During the construction of the nursery, Lantian took the agricultural researchers to the seaside, and collected wild kelp next to the reef for use. Finally, he chose mature kelp with thick leaves, flat, shiny, and thick handles. In order to avoid the selected kelp being damaged The light is stimulating, and it has to be brought back to the nursery pond for use between sunset and sunrise.

For kelp suitable for breeding, the sporangia will protrude from the epidermis, the color is dark and rough, and it looks like peeling off the skin. They can release a large number of zoospores.

Under natural conditions, mature kelp sporangia will release zoospores one after another, but cultivating kelp can speed up the process and repeatedly stimulate the sporangia by drying in the shade, so that the sporangia, like pores, suddenly absorb water and expand to release a large number of zoospores.

The zoospores will eventually attach to the seedling curtain in large quantities. The seedling curtain is a specially processed hemp rope that needs to go through processes such as dry hammering, soaking, wet beating, cooking, and weaving.

Because there is no microscope observation in Lantian, we don’t know how many zoospores are attached to each seedling curtain. We can only make a simple estimate based on the time, and then change the water and move the curtain before cultivating in separate ponds. A small attachment density will affect the emergence of seedlings, and a large attachment density will affect the number of seedlings. It hinders the growth of spores, and it is prone to large-scale disease and rot and seedling loss in the later stage.

Under limited conditions, Lantian can only increase the number of breeding samples, and let the agricultural researchers record through experiments, and finally get the optimal emergence method.

In the process of cultivating kelp seedlings, light and water temperature are very important. According to the requirements of Lantian, the agricultural researchers live and eat near the nursery. In addition to caring for the kelp seedlings, they also need to record data as much as possible.

The agricultural researchers admired Lantian very much. Lantian said that he would use the most accurate data to record the breeding experience in books, so that future people do not need to repeat the experiment, and can refer to the books on kelp cultivation.

The temptation to write a book is great. The names of these agricultural researchers who participated in the recording will appear in the final book, so they are very attentive to the cultivation of kelp, and each of them has a large amount of data records every day.

Lan Tian led the team to work hard for nearly half a year. In mid-September, the kelp seedlings were moved to the sea for temporary cultivation. The supporting breeding tools such as rafts, wooden stakes, floating ropes, and hanging ropes were completed by craftsmen during the cultivation of kelp seedlings.

From the time when the kelp seedlings were temporarily raised, Lantian involved the people of Shamoke. He used the hanging method to hang the seedlings. In addition to preventing the ropes from colliding with the wind and waves, he also had to adjust the depth of the kelp seedlings into the water at any time.

Kelp likes low temperature, and the lower the temperature, the faster it grows. Around mid-October, the kelp seedlings grow to four to seven inches.

Due to the lack of experience at the beginning, it took a long time to separate the kelp seedlings. It was not until the eve of the arrival of Gan Ning's messenger that the first batch of kelp seedlings in Lantian was completed.

Looking at the densely packed breeding rafts on the sea like vast warships, Shamoke couldn't help sighing, "Sir, you are so heavenly and human, you actually turned wild kelp into domesticated ones. You are saying that you are a god, my old man!" Sandu has to believe it."

"War horses are tamed by wild horses, and dogs that guard the house are also domesticated by wolves. Similarly, wild kelp is not unusual for domestication. But gods can ride clouds, move mountains and fill seas? Do you need to spend every day in the wind and sun with you? ?” Lan Tian shook his head and smiled wryly.

In fact, Lan Tian also heaved a sigh of relief, thinking that "it's easy to understand on paper, but you must do it yourself". He originally thought that kelp cultivation was not complicated, and at best it was a little more troublesome than mushroom cultivation, but it was a big deal. In half a year, he has hardly stopped, and his originally fair skin has turned bronze again.

Agricultural researchers have recorded hundreds of books on kelp cultivation data. After returning to Guangzhou, Lan Tian will slowly collect and sort out, and then form another agricultural book. When there are enough agricultural books, he plans to add agricultural subjects in Guangzhou Academy, or A new agricultural college was opened to train agricultural talents.

Sha Moke smiled and added: "We can't see those wild gods, but I often see you as a living god. You have instructed my clansmen to care for the kelp in the later stage, and left agricultural researchers to guide the breeding. You Are you going back to Guangzhou?"

Lan Tian nodded, "Yeah, we've spent more than half a year in Jieyang, and my daughter is one year older, and it will be Chinese New Year if we don't go back."

"Kelp can only be harvested in April or May next year. At that time, I have already gone to Linyi with General Gao, and I will have to ask Mr. to guide me then." Shamoke smiled foolishly.

"Don't worry, General Sha. Even if you don't tell me, I will come again. You have to explain the method of drying and harvesting kelp." Lan Tian nodded.

When the two were talking with emotion, Gao Yuan trotted over to report: "Sir, Governor Tan has brought General Gan's messenger here."

"Isn't Sun Quan itchy again? Let's go, let's take a look." Lan Tian walked back quickly after speaking.
