Behind the embankment. It is the first phase of high-yielding acres of land. Yanquezhi and Mo Nanhai! Daodaolu and others discussed it. It is decided to construct and renovate farmland with early maturity and high and stable yields that must meet the following standards: drought resistance to ensure a bumper harvest without rain; waterlogging to reach the standard of once in the past year and the century, and daily heavy rains to prevent disasters; and river bank flood control embankments to reach the standard of once in a year. The flood level plus level 8 winds will not collapse or spread; the flat land will be converted into soil to achieve a living soil layer depth of 1 inch for paddy fields and 2 feet for dry land. The ability to retain water and fertilizer is greatly improved.
Make fields into square grids. The square area should be large to facilitate the operation of agricultural machinery. Drainage and irrigation sub-channels. Ditches, canals, roads and forests are provided. Especially for forests, farmland windbreaks must be gradually and plannedly built to reduce the typhoon damage every summer and autumn. Field roads must be capable of driving tractor-trailer vehicles
After discussion, Yanquezhi began the surveying, mapping and design work. Wu Nanhai and Fa Shilu began to mobilize agricultural workers on a large scale to make preparations. They opened up various biogas digesters and compost pits and prepared sufficient base fertilizer. Materials for water conservancy construction are constantly being transported to the construction site from everywhere: plant ash and lime are used for soil modification. Bricks, stones, cement, wood, and bamboo rods used for pouring concrete; the machinery factory is responsible for manufacturing various valves and pipes used in water conservancy facilities. At the same time, the manufacture of water pumps, supporting boilers and steam engines was started.
The project was first started by a large number of laborers sent by Gao De, who brought axes, saws, sickles and other tools. Carry out a comprehensive cleanup of the vegetation in the entire open area. The vegetation here is mainly small shrubs and weeds. Small shrubs are used as firewood. After the weeds are harvested, they are accumulated with dead grass and fallen leaves in several temporary compost pools built by Wu Nanhai. From the biogas The mud from the pond is used as a primer to mix it up. Cover the outside with soil and water it 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. Yan Quezhi and others were already waiting for him at the headquarters, and the construction route had been marked on the map.
The first step is to use bulldozers to carry out comprehensive grading works on the open area. Remove remaining vegetation from the surface. The latter should be especially careful when removing large rocks. To avoid damaging the bulldozer blade and tracks. Next to each bulldozer is a squad of soldiers from the Army, who search in front of the bulldozer in a spread-out formation.
"This is a bit like the cooperation between Bu and Tan." Yan Quezhi climbed on the cab and said to Bai Yu.
"If the oil and spare parts of the bulldozer can be used, I won't fly to Beijing immediately. Why bother to open up wasteland and build roads here." Bai Yu stared ahead. He kept pushing and pulling the joystick in his hand. From time to time he would yell on the intercom. Other tractors are asked 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. As far as the eye can see, the tracks of the Dongfanghong tractor are crushing the ground. The tractors are filled with riflemen known as "tractor grenadiers", wearing bearskin hats and holding Minibugas.
It feels so strange! Yan Quezhi shook his head.
"Nothing is impossible." Bai Yu was full of confidence, "Small! It's not good in road 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. The protruding hardware seems to have been added later and is not original to the tractor.
What is a tour? "Yanquezhi bowed 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 specification is that it can withstand targeting A direct hit from a cannon's solid projectile from a meter away is powerful enough, right?"
"Such a big iron ball hit directly, and the people in the cab were shocked to the point where their mouths and noses bleed.
"The enemy 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 sunroof is open, bringing 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, you can beat the enemy with a half-drop and make them howl. If necessary, use grenades and grenade launchers. 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. It's a pity that there is not enough fuel.
He then talked about the several weapons he designed, which basically revolved around tractors, cars, motorcycles and even bicycles. The latest design is to install a total of four "hand-held shotguns" with two front and two rear barrels on a weighted agricultural bicycle commonly known as a flying big gun, using the speed of the bicycle to fire at close range and disturb 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. By the way, this bracket also supports pulley crossbows.
Generally speaking, the things designed by Bai Yu are relatively "modern". He scorns the things of the "retro" weapon designers headed by Lin Shenhe.
After the cleanup, the waste soil excavated during the construction surge was brought from various construction sites. Yanquezhi plans to raise Mei Taiyang as high as possible, even if it is one or twenty centimeters. This also incidentally disposes of a large amount of waste soil generated by various construction projects.
All land grading work was completed quickly. Then the tractor was attached to a heavy-duty plow for deep plowing to plow and turn the soil. A large amount of quicklime was transported from Bopu to improve the soil. So much lime was used that the supply of quicklime on all building sites was reduced by half. In addition to working overtime at the quarry, all off-duty personnel of the 6th Navy were mobilized to mine the mills on the coast to replenish raw materials for burning lime.
Construction of the Yanqueshi 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 set at a distance of more than 100 meters from the highest water level of the Wenlan River in the rainy season, serving as a flood channel during floods. When the water level is low, watermelons and peanuts are planted by taking advantage of the natural conditions of sandy soil on the river bank.
Irrigation gates and drainage gates are installed on the water surface to adapt to the layout of separate channels for irrigation and drainage. The gates are opened and closed mechanically. The power for opening and closing uses the power of the steam pumping station on the dyke.
Connecting the two gates are two main channels, both 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 canals in the field are connected to these two main canals, and manual opening and closing gates are installed at the canal mouths.
.
For the large amount of spring water flowing in from the hilly areas, simply intercepting it with drainage channels and discharging it into the Wenlan River is the simplest way to deal with it. But Yanquezhi believes that doing so is a waste of water resources. From the perspective of early prevention, he decided to use the natural terrain to build ponds and dams in hilly areas to store water. The pond dam built in this way will collect spring water and 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 lifeblood of the entire crossing group, and the amount of industrial and domestic water is also reduced.
The Tangba Reservoir built using the natural terrain of hills can not only regulate water storage but also beautify the environment. Fish can be raised in the sugar dam and used for electricity. It can be regarded as killing multiple birds with one stone. Wang Luobin had great experience in building such small water conservancy projects, so he was the general contractor for this part of the project.
In addition to building the pond and dam, 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 pond and dam. At the same time, he experimentally built a small hydropower station on a larger pond and dam. It's just that the electric power is too high and can only be used in stages, so it is of little use and is purely for research.
Farmland water conservancy infrastructure construction is proceeding vigorously.
Wu Nanhai went to the executive committee to find Ma Qianzhu. Ask him to help solve the problem of fertilizer.
Because the soil fertility in the United States is very low due to long-term internal content, applying lime can only neutralize the acidity, but cannot improve the fertility and trace element content of the soil.
Fashilu said: "Meitaiyang needs to add a lot of nitrogen, phosphorus and potassium fertilizers. Especially phosphorus fertilizers. The lack of phosphorus is so severe that even if you try to plant leguminous green manure, you won't be able to grow it. After the trace elements are adjusted, you can add farmyard manure." As a base fertilizer.”
Just applying farmyard manure and green manure seems to be a lot, but in terms of fertility improvement effect, it is far less effective than the chemical fertilizers that are popular among modern petty bourgeoisie. However, the nitric acid locks they brought became explosives for the Military Commission under the guidance of "Military Song Politics".
"Nitrogen fertilizer is easy. Let the executive committee find a way to get us brown butterfly or peat. Where can I find phosphorus fertilizer and potassium fertilizer." Wu Nanhai muttered, "There is not so 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 potash fertilizers, they can meet their demand by manufacturing potassium chloride by-product from the bitter brine industry in refined salt plants. Coupled with the bell element contained in peat lignite, it is roughly enough. , if you want to know what happened next, please visit Liuzhou.
