The chapters that are updated in the middle of the night are usually anti-daban chapters. I have tried to choose when it is late at night, and there are few people watching them at this time. Generally, anti-daban chapters will be modified to the correct content at least half an hour.

It's okay to read on the computer, and it's okay to automatically subscribe with the mobile app. As long as I haven't clicked on the chapter before I modified it. Once I clicked on it, the wrong chapter content will be downloaded and entered into the mobile phone cache. At this time, even if I modify the mobile client, it is still the wrong content and will never change.

At this time, you can only download this chapter again. If it doesn’t work, you can only delete the book and remove it, and then add it again and put it on the shelves.

There are few people reading niche books, and daban is rampant. There is no way to do so. I can't make it. I'm sorry.

This book was first released (start)*(click)*(Chinese)*(net), please support the official version reading, thank you.

"The southern Patagonia region north of the Magellan Strait is an extremely desolate and barren area. According to statistics, about 73% of the land here is bad." At the end of December 1649, Li Dayan lay down on his suitcase and took the time to write his interview manuscript: "Is there any more miserable place than these wastelands full of gravel and sparse grass? I noticed that the residents of these areas were so anxious to find fuel for cooking and heating. They even cut the reeds to burn fire, burn whatever they caught, and they stopped until some coal gangue was transported over to the Black Mountain coal mine. Only fertile land is available here on the gullies and the wet river bank, and the livestock are also skinny and pitiful..."

What Li Dayan described was the rural situation outside Xingnan Port. There is no doubt that the land here is extremely barren. Except for the relatively fertile land on the river bank, there are large areas of desert everywhere. Sparse bushes and weeds grow on the desert, which indicates that the planting industry here will inevitably lead to bloodshed.

Recently, the Nantec Corporation launched an action to transform soil and irrigation facilities nearby, and included it in the 1650 work plan, and also prepared a special fund of up to 250,000 yuan in finance. The Nantec Corporation believes that in such a drier inland saline-alkali irrigation water-poor area, if the limited precipitation (less than 300 mm) and the nearby Xingnan River water are fully utilized, and permanent irrigation facilities for bricks, stone and cement are built, and water-saving irrigation agriculture is vigorously promoted, the place may not be able to build a self-sufficiency grain production system.

Of course, when developing agriculture here, you must also pay attention to the local environmental tolerance. Excessive sourcing of soil will only lead to lower groundwater levels, degradation of vegetation, salinization of soil, desertification, and the effect of sand-proof barriers in the Xingnan River Basin will become increasingly effective, and then cause spring monsoon disasters and summer droughts, which will eventually lead to a complete collapse of the local ecological system. Therefore, increasing the water-saving awareness of residents here, controlling the amount of irrigation water, and building a water-saving irrigation system in the vast reclamation areas is the top priority for Nantec Corporation, which is interested in developing here.

In the middle of last year, the Nan Railway Company took advantage of the local construction gap to organize people to build four artificial reservoirs in the lower reaches of the Xingnan River. The reservoir outlet has a flood control device. On the one hand, when the water volume of Xingnan River is relatively abundant in spring, it can guide the huge floods washed down from the upstream into the reservoir (the storage capacity is not very large, with an average of more than 200,000 cubic meters per day) to prevent precious freshwater resources from flowing into the sea in vain. Because once the evaporation volume increases greatly in summer, the river water level drops rapidly, and there is almost no rainfall, everyone will have to sit on wax.

Moreover, when the tide level of this reservoir increases outside the sea in winter, the sea water flows backwards and causes the salt content of the Xingnan River to increase rapidly, it can greatly reduce the degree of "pollution" of the river. In addition, these reservoirs also bring an unexpected surprise to the people of the east coast who live here - that is, the sludge accumulated in the reservoir.

As we all know, the Xingnan River is a very seasonal river. It almost drys out during the dry season, but during the flood season, the violent ice and snow melt water will cause a huge spring flood in a short period of time. This fierce flood will flush down nutrient-rich substances such as soil, rotten animals and plants, human and animal feces in the middle and upper reaches - this is how the shallows are everywhere at the mouth of the Xingnan River. In addition, the surging river water can cut nearby gravel (typical components of gray brown desert soil) into fine soil particles, which helps to improve the soil texture.

After a flood period, the artificial reservoir built last year was very happy to find that mud layers ranging from 5-8 cm had been deposited at the bottom of the reservoir. These mud layers are rich in nutrients, and the soil particles are much thinner than the Gobi gravel soil at the bottom of the reservoir. It can be used to cover the upper layer of the gravel soil to improve the soil texture and enable crops to be sown.

From this perspective, a scholar from the Nantie Company who was born in the Corps Fort pointed out that everyone can transform some places with brown desert soil into reservoirs, and then flood the turbid floods washed down from the upstream during the spring flood. After a few years, the brown desert soil that was originally not suitable for cultivation will inevitably be covered with a layer of fine grain loess rich in nutrients, which is a very large fertile field. Moreover, because there is a very thick layer of gravel under these brown desert soils, the leakage will stop after the flood is silted to a certain extent, and then eventually flow to other nearby places. The groundwater here is also replenished, so that some deep-rooted plants can have sufficient water source to grow, avoid land desertification, and improve soil quality.

The suggestion of this scholar was quickly taken by superiors. After sufficient demonstration and research, the staff of the Ministry of Agriculture who came from the local government unanimously agreed that this policy was feasible. Therefore, the suggestion was quickly adopted by the Nantie Company and included it in the plan to be implemented. The young scholar himself received a huge bonus of up to 500 yuan, which was also given priority by superiors when it was promoted, and it was once circulated as a good story in the company system.

Of course, these newly silted lands cannot be planted rashly in the previous few years. In the first few years, alfalfa, a "green manure" crops that can fix nitrogen must be planted here in large quantities, while providing feed to livestock, while improving soil texture. After persisting for a few years, the soil composition of this flooded land will be greatly improved. Not only will the nitrogen increase in a large amount, but the content of phosphorus has also been greatly improved. Because the huge root system of alfalfa will produce a large amount of organic acids, it will convert the calcium-fixed phosphorus element in the soil here into a fast-acting phosphorus element that can be quickly absorbed by plants, which is of great significance.

Given the special climate, barren land and other factors in the Southern Patagonia region, the crops planted on the arable land on both sides of the Xingnan River are also very different from those in the local area. According to the suggestion of Jin Kola, vice president of Nantec Corporation, these lands should be adapted to local conditions and cannot be generalized. Corn, sorghum (drought-tolerant, barren-tolerant, deep-root crops), soybeans, alfalfa, rapeseed, and beets can all be planted. Alfalfa can increase nitrogen in the soil (also a small part of phosphorus), soybeans can increase nitrogen in the soil, rapeseed beets, etc. can increase phosphorus. These categories should be rotated with grains to ensure that the fertility in the soil does not dissipate quickly, resulting in the land being thinner and thinner as it grows, and finally exhausts nutrients and returns to desertification.

In addition, the most important agricultural infrastructure in the Xingnan River Basin is probably the construction of brick and stone cement irrigation canals. These permanent canals can effectively prevent irrigation water from leaking. If they are covered with wooden boards, they can also prevent some evaporation. They are definitely an indispensable facility here.

"Nan Railway Company has launched an epic environmental transformation activity here..." Li Dayan, who purchased the 1,000 yuan bond of Nan Railway Company, thought about it and decided to add some information to his documentary interview and boast about Nan Railway Company: "After this group of new immigrants arrive, together with nearly 2,000 old settlers here, a large area of ​​dense field irrigation system will be built along the banks of Xingnan River under the arrangement of Nan Railway Company. Different from the extensive irrigation method of flooding the local waters, the Xingnan River area mainly adopts fine ditch irrigation, and even uses pipe drip irrigation measures in some areas, and tries to improve the utilization rate of fresh water, achieve precision irrigation and scientific irrigation."

Of course, building an irrigation canal is an amazing project. With the residents around Xingnan Port, it is not possible to complete overnight. Moreover, the Nan Railway Company is in financial difficulties, and I don’t know when the promised investment of 250,000 yuan will be allocated. If the money is not enough, where does the massive bricks, stones, lime, cement, and wooden boards required for the canal come from? Taking a step back, even if these materials are complete, there are still a large number of infrastructure projects to be completed in Xingnan Port Terminal, not to mention the construction of the Liangyang Railway, which has begun, which is a huge pit that attracts labor.

Therefore, to complete these infrastructure projects, we must rely on the efforts of the officers and soldiers of the Nantik Road Protection Team, that is, to see how many Crandy slave workers they can capture from the La Plata area. In addition, we must also see in South Africa. The local South African troops, which are currently commanding for victory, have set up bandit suppression headquarters in Gundam Fort, and are preparing to dispatch large troops to the Little Kalu Plateau to "suppress bandits" to capture more black slaves and send them to the South Patagonia area for South Railway Company to drive. This incident was facilitated by the unanimous greetings of several veterans of the Army Department.

However, can we stump our wise and hardworking Ming immigrants if we don’t have water conservancy facilities? From the first day of settlement, these Ming immigrants began the transformation process of the land allocated to themselves. They got up early and went to the riverbed to dig soft and fertile silt (the nearby riverbed silt has been dug by the first person), and then carried it back to their own fields. The initiative is many times stronger than those settlers in Italy and Livornia.

While transporting silt fields, they also followed Xingnan Highway to find a sandbank area with abundant water and grass, and cut large bales of hay from there. In order to get these hay, they often had to walk on the edge of the desert for several days, overcome the difficulties of hunger and thirst, and bring back the feed that the livestock urgently needed. Under the shocking care, the Andalusian black cows assigned to them quickly recovered from their skinny state. According to Li Dayan's observation, although the livestock raised by the Ming people were short-lived, they were often better than those relatively free and casual Italian immigrants. They were fat and strong, which made the European immigrants blush and felt embarrassed to be lazy when doing daily farm work.

There is no doubt that these "colonists" from Shandong, Daming were very disappointed with the barrenness and desolation of the land under their feet. But they were not desperate, but with their enthusiasm, they prepared to build this desolate land into a beautiful desert oasis bit by bit.
