Section 161 Farmland Construction

Behind the embankment is the first phase of 1,500 acres of high-yield fields. Yan Quezhi, Wu Nanhai, Fa Shilu and others discussed and decided to build and transform the farmland to ensure harvests while drought and flood, and high-yield and stable yields. High-yield and stable yields must meet the following standards: drought resistance reaches 90 days without rain to ensure bumper harvests; drainage reaches once in 10 years (according to the 20th century standard), and heavy rains will not cause disasters on the 5th; river bank flood control embankment reaches the flood level once in 20 years and level 8 winds will not collapse or overflow; the soil is changed to the plain to make the living soil layer of the paddy field 5 inches deep and the dry land is 1 foot. The water and fertilizer retention capacity has been greatly improved.

The fields should be built into squares, and the square area should be large to facilitate the operation of agricultural machinery and equipment. Drainage and irrigation canals, ditches, canals, roads and forests. Especially for forests, farmland windproof forests should be gradually and planned to reduce the impact of typhoons in summer and autumn every year. Field roads should reach the level of driving motor-cultivating vehicles.

After discussion, Yanquezhi began to survey and design. Wu Nanhai and Fa Shilu began to mobilize farmers and workers on a large scale to prepare, and put various biogas tanks and compost tanks into the pond and prepare sufficient base fertilizer. Water conservancy construction materials were continuously transported to the construction site: wood ash and lime were used for soil modification. Bricks, stones, cement, wood, and bamboo bars for pouring concrete for dam channels; various valves and pipelines used in water conservancy facilities manufactured by the machinery factory were responsible for the manufacture of various valves and pipelines. At the same time, water pumps, supporting boilers and steam engines were started.

The project was first launched by a large number of laborers sent by Wu De. They carried tools such as axes, saws, sickles and other tools to carry out a comprehensive cleaning of the vegetation in the entire development area. The vegetation here is mainly small shrubs and weeds. Small shrubs are used as firewood. After the weeds are harvested, they are piled up in several temporary compost pools built by Wu Nanhai. The worm mud that comes out of the biogas pool is used as a guide to mix it, and then covered with soil and watered regularly. In the summer sun, these plants and trees will soon be decomposed into organic fertilizer.

If they are buried directly in the soil, some plants with heavier fiber quality will not decompose even after many years, and will not play a role in fertilizing the fields.

After cleaning up the vegetation, four bulldozers led by the armored soldier commander Bai Yu came, and the Dongfanghong tractor was equipped with bulldozing shovels. Bai Yu poked his head out of the cab. Yan Quzhi and others were waiting for him in the command center, and the construction route had been marked on the map.

The first step is to use bulldozers to carry out comprehensive flat ground engineering on the developed area. Remove residual vegetation on the surface and remove large stones - the latter should be especially careful to avoid damage to the bulldozer shovel and tracks. Each bulldozer is equipped with a squad of army soldiers, which are scattered formations and search in front of the bulldozer.

"This is a bit like Bu Tan's coordination." Yan Quzhi crawled on the cab and said to Bai Yu.

"If the oil and spare parts of the bulldozer can be used open, I won't be able to hit Beijing immediately, so why should I find it hard to open up the land and repair the road here?" Bai Yu stared at the front, constantly pushing and pulling the joystick in his hand. From time to time, he shouted in the intercom, asking other tractors to "pay attention to the distance between each vehicle and maintain coordination."

"Tractor Armored Division?" This scene immediately appeared in front of Yan Quzhi's eyes: smoke and dust rolled on the dirt road, and the tracks of Dongfanghong tractor that could not be seen crushed the earth. The tractor was full of rifle soldiers known as "Tractor Grenadiers", wearing bearskin hats and holding Minni rifles...

It feels so strange! Yan Quzhi shook his head.

"Isn't it impossible?" Bai Yu was full of confidence. "The mountain roads and water network areas are not good, but they are definitely powerful tools on the North China Plain. Look at this-" He pointed to the several protruding hardware outside the cab-these things seemed to be installed later, not the original tractor.

"What is this?" Yan Quzhi asked loudly.

"Hanging the fixtures of the armor plate." Bai Yu was very proud. This was designed and manufactured by him himself. "When needed, the key part of this tractor can be fully armed in half an hour, inseparable from swords and guns. The bulletproof specification is to withstand the direct hit of a 400-meter-way solid bullet from a 6-pound cannon. Isn't it strong enough?"

"Such a big iron ball hit directly, and the people in the cab were still trembling with bleed from their mouths and noses."

"The enemy must be beaten." Bai Yu seemed not very worried about this, "Besides, we are not sitting and being beaten. Look at it."

On the top of the tractor, something like a car sunroof was opened, surrounded by something like a slide rail. The sunroof is open, bringing some cool breeze to the hot cab.

"I made a modification kit, which can directly add a rotating turret to the roof of the car on the sunroof. Even if there is no machine gun, you can still beat the enemy with a 56 and a half. If necessary, use grenades and grenade launchers - invincible."

“It’s really creative—”

"What's this? I've studied weapons design and engineering design major." The former armored soldier officer was very proud. "There is also a fire-spraying tractor modification kit. Unfortunately, the fuel is insufficient, so the executive committee refused to test it."

Then he talked about several weapons he designed, basically around tractors, cars, motorcycles and even bicycles. The latest design is to install four "handheld shotguns" on the weighted agricultural bicycle commonly known as 28-bars, with four pipes of front two and rear two, and use the bicycle's rapid motor power to close the launch and strike the opponent's formation. Another modification is to install a fixed bracket for rifle shooting on the bicycle, which is used for cyclists to fire at the same time while riding a bicycle. By the way, this bracket also supports pulley crossbows.

In short, Bai Yu designed things relatively "modern", and he scoffed at the things of the "retro" weapon designers led by Lin Shenhe.

After cleaning up, the waste soil excavated during the construction tide was transported from various construction sites. Yanquezhi was preparing to raise the United States, Taiwan and Ocean as much as possible, even if it was 10 or 20 centimeters. This also dealt with a large amount of waste soil generated by construction in various places.

All the land leveling work was completed quickly. Then the tractor hung a heavy plow for deep plowing and deep plowing and pouring soil. A large amount of quicklime transported from Bopu for soil improvement. The large amount of lime used reduced the supply of quicklime on all construction sites by half. In addition to working overtime in the quarry, all the personnel who did not work on duty in the Army and Navy were mobilized to mine oyster houses on the coast to replenish the raw materials for burning lime.

Construction of Yanquezhi's dam has also begun. Due to the cost, this dam uses a gravity earth dam with a simple structure, and multiple rows of wooden piles are inserted for reinforcement. The outer edge of the earth dam is covered with stones. The entire dam is more than 100 meters away from the highest water level in the Wenlan River during the rainy season. As a flood passage during floods, when the water level is low, watermelons and peanuts are planted using natural conditions with a lot of sand on the river bank.

Irrigation gates and drainage gates are opened on the dam to adapt to the arrangement of separate channels for irrigation and drainage. The gates are opened and closed in a mechanized manner, and the power to open and close uses the power of the steam pumping station on the dam.

The two main channels are connected to these two gates, all of which are built of bamboo reinforced concrete. The design flow standard leaves sufficient margin to meet the needs of irrigation and drainage in extreme environments. Other irrigation and drainage channels in the fields are connected to these two main channels, and gates for opening and closing of manpower at the entrances are set up.

For a large amount of spring water flowing from the hilly areas, simply intercepting it with drainage canals and discharging it into the Wenlan River is the easiest way to deal with it. However, Yanquezhi believes that doing so is a waste of water resources. From the perspective of drought prevention, he decided to use natural terrain to build pond dams in hilly areas for water storage. The construction of pond dams in this way is small in volume. The pond dam gathers the spring water and irrigates the farmland during the dry period of the Wenlan River to reduce the amount of water in the river - after all, this river is now the lifeblood of the entire crossing group, and the amount of industrial and domestic water is not small.

Tangba Reservoir built with the natural terrain of hills can not only adjust the water storage capacity and beautify the environment. Fish can be raised in the sugar dam to generate electricity. It is a killing of one stone. Wang Luobin has a lot of experience in building such a small water conservancy project, so he will take the general contracting of this part of the project.

In addition to building the pond dam, Wang Luobin also selected several economic tree species in the nursery of the farm that adapted to the local climate to green the hills around the pond dam. At the same time, he experimentally built a small hydropower station on a larger pond dam. However, the power generation power is too small, and it can only generate electricity in stages. It is of little use and is purely a research nature.

The basic construction of farmland water conservancy is in full swing. Wu Nanhai went to the Executive Committee to find Ma Qianzhuo and asked him to help solve the fertilizer problem.

Because the long-term waterlogging in the United States, Taiwan and Oceania caused poor soil fertility. The application of lime can only neutralize acidity and cannot improve the soil fertility and trace element content.

Fa Shilu said: "The United States, Taiwan and the United States need to add a large amount of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer. Especially phosphorus deficiency is very severe. If you want to plant green fertilizer in legume, you can't grow it. After adjusting the trace elements, add farm fertilizer as the base fertilizer."

The application of farmhouse fertilizer and green manure alone seems to be a large number, but in terms of improving fertility, it is far less useful than the fertilizers that are tempted by modern petty bourgeoisie. However, the ammonium nitrate they brought has become the explosives of the Military Commission under the guidance of the "Primary Army Politics".

"Nitrogen fertilizer is easy, let the Executive Committee find a way to get us lignite or peat. Phosphorus and potassium fertilizers, where can I find it?" Wu Nanhai muttered, "There is not so much bone meal."

"Bronze and peat are good," said Fashilu. "Natural compound fertilizers, including nitrogen, phosphorus and potassium, are much more efficient. However, for improved soil, the amount is not large enough. It is best to have special phosphorus fertilizers and potassium fertilizers."

They can rely on the bitter salt factory's bitter brine industry to produce potassium chloride by-products to meet their needs. In addition, the potassium element contained in peat lignite is roughly enough.
