Compared with large rivers like the Huai River, it is much easier to dam and intercept inland rivers. In some Baogan areas, it even only takes two or three days to complete the interception and closure of small cofferdams.
After making a large amount of bamboo bars into a cage, you can fill it with stones. If the water flow is not very strong, it is basically impossible to open it.
As long as the cofferdam is successful, the rest is to drain the water, then cover the outside with soil to form a long slope, and then cover the slope with concrete.
Of course there is no concrete, but you can plant trees, usually willows.
The next thing to do is to conduct regular inspections and supervision for decades to prevent anyone from loosening the soil to grow vegetables on the dam.
Dredging is relatively troublesome, but because you need to replant a crop of rice, the silt mixed with paddy soil is actually a fertilizer replenishment. As long as there is no unlucky thing about the rice flowering and not bearing fruit, you can always harvest something.
At the same time, due to the special population structure of Huaizhong City, it is impossible to plant a large amount of rice. Instead, legume crops are heavier.
In addition, there are vegetables, such as fungus, eggplant and other crops, which have relatively low requirements for field management and can continue to supply output. Relatively speaking, the consumption of staple grains will also be greatly reduced.
Especially eggplant, when Huaizhong City was still Zhoulai City, the local specialty was Dongguo's "Luosu".
The so-called "Luosu" is the dialect name for eggplant.
In fact, Li Jie was on the Huai River, preparing to launch a surprise attack on Zhou Laicheng. That place was called Qie Di.
Even now, eggplant is a specialty of some villages in Huaibei.
It's just that unlike the purple-skinned eggplants in President Li's impression, Huaibei's eggplants are mostly white-skinned, or white with a slight purple tint.
The reason why we chose eggplant among the replanted crops is that it not only enriches the dining table, but also has a high yield.
And the way to eat it is not particular, just boil it in plain water and then dip it in salt.
The food that satisfies hunger is about quantity.
The eggplant yield per mu really impressed President Li.
When he was still a foreman, he was building vegetable greenhouses for people. Eggplants were grown in that greenhouse, with a yield of 10,000 jin per mu, a yield of 8,000 jin per mu, and another greenhouse... a yield of 15,000 jin per mu.
Especially the last one, the eggplant is actually spherical.
The reason why eating eggplant is not important to President Li is because he really had enough eggplant at the beginning and ate it every day, leading his worker apprentices to compete with eggplant every day.
It was actually quite difficult to monetize the eggplants. Selling them cheaper meant making some hard-earned money. In the end, more than two thousand kilograms of eggplants were left in the canteen, which almost made the chef in the canteen almost suffer from schizophrenia.
President Li thought, if the field management is not very particular, the yield of 10,000 jins per mu may not be achieved. At a 30% discount, the yield of 3,000 jins per mu should still be achieved.
Providing a stable supply of vegetables to several construction sites before winter is a matter of great merit.
As for the last bit of eggplant tree, burning it as firewood can be regarded as waste utilization.
In addition to eggplant, fungus is also a very easy vegetable to manage. This kind of vine vegetable can be grown in ordinary paddy soil with river mud as a base fertilizer and a certain amount of plant ash. With normal planting, the yield per mu is generally more than 3,000 kilograms.
As for how to eat it, it’s the same as eggplant, there’s no need to pay attention to it, just boil it in plain water and dip it in salt.
Of course, if President Li eats it himself, he will most likely stir-fry it. Add some garlic obtained from the Western Regions in the Qin State, sauté it until fragrant and stir-fry it, and you will have a delicious dish in just a few minutes.
This crappy thing is called "Luokui" and it grows very fast. Once it starts to spread, you will pick the leaves one day and another one will grow the next day, which is much more exaggerated than leeks.
It can be said that it has really been done, and it is endless and endless.
If people really don't want to eat it, they can feed it to poultry and livestock. They don't even eat poultry and livestock, but chop them all up and use them as feed for herbivorous fish.
Elephant Li Caihua in Jiangyin City likes to eat this when there is no fodder in Hekou.
Even if she eats hundreds of kilograms a day, she is not afraid of Li Caihua depriving Yinxiang of poverty.
With planning in place, those places where the cofferdams had been successfully desilted early had formed a very comfortable scene. When the engineering team began to move to the next area, the farmers who had leveled the land after clearing the site began to seize the time to replant a crop.
Grain vegetables.
At the same time, due to their simplicity, the places where dredging occurs are often small lakes or ponds. Such low-lying areas have natural streams and small ditches connecting them.
Transforming these natural creeks and ditches into temporary irrigation canals, and then setting up water trucks to irrigate them, naturally saves time and effort.
President Li did not ask for a one-step process to directly transform the land into high-yielding rice fields.
Field management and field operations themselves require time and accumulation.
The reasons for increasing the total number of manageable acres now are, firstly, for emergency purposes, and secondly, to stabilize the Huaihe River situation.
So during this period, regardless of how much the modified land can produce, as long as it can produce crops that can be eaten by humans and animals, it will be a great success.
At that time, Princess Guiyao, the "Peach Blossom Fairy" of Chen Kingdom, was due to give birth. In order to support Shaha and Yun Zhenlu, Li Jie took the time to go to Huainan to inspect the progress of the project.
In fact, he did not pay attention to the progress of the project. The reason why he went to Huainan to show off was simply to tell the Huainan countries and barbarian tribes that the King of Wu ordered the strong man Jiangyinzi Huai Shuibo to attach great importance to Huainan.
After all, the crocodile people who followed Shah and Yunzhenlu to cross the south were few brave men, and most of them were righteous soldiers, righteous followers, servants and slave laborers.
After seeing Li Jie's appearance, these people will feel more at ease working in Huainan, and will not have random thoughts and be easily incited by others, thinking that Li Jie is planning to kill them in Huainan.
On the other side of Xia Rui, the Shenduanshui River enters Huaikou. On both sides of the Shenduanshui River, which is dozens of miles deep, it is obvious that the sparkling scene has been greatly reduced.
There were originally a terrifying number of swamps and ponds, but after drainage, the bottom layer was finally exposed to the sun.
Either direct sunlight exposure to evaporate the water, or river dredging and then covering with soil, and even after extremely primitive labor hours of stacking, the effect is also remarkable.
The entire two sides of Shenduanshui have clearly been planned.
Although there is no great emphasis on field work, the ridges and furrows are obvious and very regular.
The flat land that has been plowed has been re-watered, and then a second stage of fine plowing is carried out. After that, the fields need to be leveled, then laid into a flat surface, and then rice seeds are sown for seedling cultivation.
Wait until the rice seedlings are almost grown before dividing the seedlings and transplanting them.
If there is no advance planning, it is obvious that rice cultivation will occupy a large number of agricultural people in the future.
Fortunately, the Huaishui Bofu had already estimated that the main agricultural work would not be rice planting, but the cultivation of high-yielding vegetables for emergency use.
Unlike staple foods that require intensive cultivation and careful care, things like "Luokui" can withstand even floods and still produce yields as long as they don't encounter severe droughts.
As Li Jie's inspection appearances in Huainan became more and more frequent, the small groups of Jingman and Yihu attacks that had occurred from time to time gradually disappeared without a trace as Li Jie traveled south to inspect.
When Shah organized a fleet to encircle and suppress the barbarians, he found that these barbarians no longer ventured north at all, preferring to try their luck near Juchaoyi.
