Behind the embankment is the first phase of 1,500 acres of high-yield farmland. Yanquezhi, Wu Nanhai, Fa Shilu and others discussed and decided to build and transform drought- and flood-guaranteed harvests. High-yield and stable-yield farmland must meet the following standards: drought resistance to 90 days without rain to ensure a bumper harvest; waterlogging drainage
Reaching the once-in-10-year flood level (according to 20th century standards), a 5-day heavy rain will not cause disaster; the river bank flood control embankment reaches the flood level that occurs once in 20 years plus level 8 winds and will not collapse or spread; the flat land will be converted into soil to achieve a depth of 5 inches of active soil in paddy fields.
, 1 foot on dry land. The ability to retain water and fertilizer is greatly improved.
The fields should be formed into square grids, and the square area should be large to facilitate the operation of agricultural machinery. Drainage and irrigation should be divided into channels. Ditches, canals, roads, and forest supporting facilities. Especially for forests, farmland windbreaks should be gradually and plannedly built to reduce the number of windbreaks every summer and autumn.
Due to the typhoon damage, field roads must reach a level capable of driving tractor-trailer vehicles.
After the discussion was completed, Yanquezhi began the surveying and design work. Wu Nanhai and Fa Shilu began to mobilize agricultural workers on a large scale to prepare for the various biogas digesters and compost pits, and prepared sufficient base fertilizer. A steady stream of water conservancy was provided everywhere.
Construction materials are transported to the construction site: plant ash and lime are used for soil modification; bricks, stones, cement, wood for building dams and channels, and bamboo bars for pouring concrete; the machinery factory is responsible for manufacturing water conservancy facilities
Various valves and pipes were used. At the same time, the production of water pumps, supporting boilers and steam engines was started.
The project was first carried out by a large number of laborers sent by Wu De. They brought axes, saws, sickles and other tools to conduct a comprehensive clearing of the vegetation in the entire development area. The vegetation here was mainly small shrubs and weeds. Small
Shrubs are used as firewood. After weeds are harvested, they are piled with dead grass and fallen leaves in several temporary compost pools built by Wu Nanhai. The sludge from the biogas pool is used as a primer to mix them. The outside is covered with soil and watered regularly.
, under the summer sunshine, these grasses and trees will soon decompose into organic fertilizer.
If you bury them directly in the soil, some fibrous vegetation branches and leaves will not decompose even after many years and will not be able to fertilize the fields.
After clearing the vegetation, four bulldozers led by Armored Corps Commander Bai Yu arrived, and the Dongfanghong tractor was equipped with a bulldozer. Bai Yu poked his head out of the cab. Yanquezhi and others had been waiting at the headquarters.
Looking at him, the construction route has been marked on the map.
The first step is to use a bulldozer to carry out a comprehensive leveling project on the developed area. Remove the remaining vegetation on the surface and remove large rocks - the latter must be especially careful to avoid damaging the bulldozer and crawler tracks. There is a machine beside each bulldozer.
Army soldiers from the previous class spread out to search in front of the bulldozer.
"This is a bit like the cooperation between Butan and Tan." Yan Quezhi climbed on the cab and said to Bai Yu.
"If the oil and spare parts of the bulldozer can be opened and used, I won't go to Beijing immediately, why bother to open up wasteland and build roads here." Bai Yu stared ahead, constantly pushing and pulling the joystick in his hand. From time to time, he would
Yell a few times into the intercom, asking other tractors to "pay attention to the distance between vehicles and maintain coordination."
"Tractor Armored Division?" A scene like this immediately appeared in front of Yanquezhi's eyes: smoke and dust billowing on the dirt road, the tracks of Dongfanghong tractors that could not be seen to the end were crushing the ground, and the tractors were filled with so-called "tractor grenadiers"
A rifleman wearing a bearskin hat and holding a minie rifle...
It felt so strange! Yan Quezhi shook his head.
"Nothing is impossible." Bai Yu was full of confidence. "It's not good on mountain roads and water network areas, but it is definitely a weapon on the North China Plain. Look at this -" He pointed to a few people outside the cab.
Protruding hardware - these appear to have been added later and are not original to the tractor.
"What is this?" Yanquezhi asked loudly.
"The fixings for hanging the armor plate." Bai Yu was very proud that he designed and manufactured this himself. "When needed, the key parts of this tractor can be fully armed in half an hour, making it invulnerable. The bulletproof specifications are able to withstand 6
A direct hit from a 400-meter solid projectile from a pounder cannon, isn’t it powerful enough?”
"Such a big iron ball hit it directly, and the people in the cab were shocked to the point where their mouths and noses bleed."
"The enemy also has to hit the target." Bai Yu didn't seem too worried about this, "Besides, we are not just sitting around and being beaten. Look above."
On the top of the tractor, there is a new thing similar to a car sunroof, surrounded by things like slide rails. The skylight is open to bring some cool breeze into the hot cab.
"I made a modification kit that can add a rotating turret directly to the roof above the sunroof. Even if there is no machine gun, I can beat the enemy with a 56 and a half, and use grenades and grenade launchers when necessary.
--Invincible."
“So creative——”
"What does this mean? I studied weapons design and engineering design." The former armored force officer was very proud. "There is also a fire-breathing tractor modification kit. Unfortunately, there is not enough fuel, and the executive committee is unwilling to test it."
Then he talked about the several weapons he designed, which are basically based on tractors, cars, motorcycles and even bicycles. The latest design is to install two in front and two in rear on a weighted agricultural bicycle commonly known as 28-bar.
The four-barreled "hand-held shotgun" uses the rapid maneuverability of the bicycle to fire at close range and disrupt the opponent's formation. Another modification is to install a fixed bracket for rifle shooting on the bicycle so that the cyclist can
Shoot while riding a bike. By the way, this bracket also supports roller crossbows.
Generally speaking, the things designed by Bai Yu are relatively "modern", and he scorns the things of the "retro-style" weapon designers headed by Lin Shenhe.
After the cleanup, the waste soil excavated during the construction surge was transported from various construction sites. Yanquezhi planned to raise the Meitaiyang as high as possible, even one or twenty centimeters. This also dealt with the waste generated by the construction at various locations.
A lot of wasteland.
All the land leveling work was completed quickly. Then the tractor was attached to a heavy-duty plow for deep plowing, and the soil was turned over. A large amount of quicklime transported from Bopu was applied to improve the soil. The amount of lime was so large that all buildings were
The supply of quicklime on the construction site was reduced by half. In addition to the overtime work in the quarry, all off-duty personnel of the army and navy were mobilized to mine oyster houses on the coast to replenish raw materials for burning lime.
The construction of Yanquezhi's dam has also begun. Due to cost constraints, this dam uses a gravity earth dam with a simple structure, with multiple rows of wooden piles driven in for reinforcement. The entire outer body of the earth dam is covered with stones. The entire dam is separated from
During the rainy season, a distance of more than 100 meters is set aside between the highest water levels of the Wenlan River to serve as a flood channel during floods. When the water level is low, watermelons and peanuts are planted using the natural conditions of sandy soil on the river bank.
Irrigation gates and drainage gates are set up on the dam to adapt to the layout of separate channels for irrigation and drainage. The gates are opened and closed in a mechanized manner, and the power for opening and closing uses the power of the steam pumping station on the dam.
Connecting the two gates are two main channels, all constructed of bamboo reinforced concrete. The design flow standards leave sufficient margin to meet the needs of irrigation and drainage in extreme environments. Other irrigation and drainage channels in the field are connected to
On these two main canals, manual opening and closing gates are installed at the canal mouths.
For the large amount of spring water flowing in from the hilly areas, it is the simplest way to simply intercept it with drainage canals and discharge it into the Wenlan River. However, Yanquezhi believes that this is a waste of water resources. From the perspective of drought prevention, he decided
Use the natural terrain to build ponds and dams in hilly areas to store water. The construction of ponds and dams in this way is small. The ponds and dams gather spring water to irrigate farmland during the dry season of the Wenlan River, reducing the amount of water taken from the river. After all, this river is now the entire
Crossing the lifeblood of the group, industrial and domestic water consumption is not small.
The Tangba Reservoir built using the natural terrain of the hills can not only regulate water storage and beautify the environment. Fish can be raised in the Tangba Dam and used to generate electricity. It can be regarded as killing multiple birds with one stone. Wang Luobin has great experience in building such small water conservancy projects, so this part of the project
He was the general contractor of the construction.
In addition to building ponds and dams, Wang Luobin also selected a number of economic tree species adapted to the local climate in the farm's nursery to green the hills around the ponds and dams. At the same time, he experimentally built a small hydropower station on a larger pond and dam. It only generates electricity.
If it is too small, it can only generate electricity in stages and is of little use. It is purely for research purposes.
The infrastructure construction of farmland water conservancy is proceeding vigorously. Wu Nanhai went to the executive committee to find Ma Qianxu and asked him to help solve the fertilizer problem.
Long-term waterlogging in the United States has resulted in poor soil fertility. Applying lime can only neutralize the acidity, but cannot improve soil fertility and trace element content.
Fashilu said: "Meitaiyang needs to add a lot of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer. Especially phosphorus fertilizer. The lack of phosphorus is so severe that even if you try to plant leguminous green manure, it will not grow. After the trace elements are adjusted, farmyard manure can be added."
As a base fertilizer.”
Just applying farmyard manure and green manure seems to be a large amount, but in terms of fertility improvement effect, it is far less effective than the chemical fertilizers that modern petty bourgeoisie have become dissatisfied with. However, the ammonium nitrate they brought has become a good product under the guidance of "Songjun Politics"
Explosives from the Military Commission.
"Nitrogen fertilizer is easy. Let the executive committee find a way to get us lignite or peat. Where can I find phosphate fertilizer and potash fertilizer?" Wu Nanhai muttered, "There is not that much bone meal."
"Both lignite and peat are good," Fashilu said. "Natural compound fertilizers include nitrogen, phosphorus, and potassium, which are much more efficient. However, the amount is not large enough to improve the soil. It is best to have specialized phosphate fertilizers.
and potash.”
For potassium fertilizer, they can rely on the potassium chloride by-product produced by the bitter brine industry in refined salt plants to meet demand. In addition, the potassium contained in peat lignite is roughly enough.
