Chapter 373 Farmland Construction

大堤后面，是第一期1500亩的高产田。燕雀志和吴南海、法石禄等人会商下来，决定建设改造旱涝保收、高产稳产农田必需达到以下标准：抗旱达到90天无雨保丰收；排涝达到10年一遇（按20世纪标准），5日暴雨不成灾；河岸防洪堤达到20年一遇洪水位加八级风不溃不漫；平地改土做到水田活土层深5寸，旱地1尺。保水保肥能力大为提高。

The field is made into a grid, and the area of ​​the grid should be large to facilitate the operation of agricultural machinery.Drainage and irrigation sub-channels.Ditches, ditches, roads and forests.Especially for forests, it is necessary to gradually build farmland windbreak forests in a planned way to reduce the typhoon disturbance in summer and autumn every year.The roads in the field should reach the level that can drive the machine farming vehicles

After discussing it properly, Yanquezhi started the surveying, mapping and design work.Wu Nanhai and Fa Shilu began to mobilize agricultural workers on a large scale to prepare for the preparation of various biogas digesters and compost ponds to prepare sufficient base fertilizer.Materials for water conservancy construction are continuously transported to the construction site everywhere: plant ash and lime are used for soil modification.Bricks, tiles, stones, cement, wood, and bamboo bars for pouring concrete for building dikes and channels; various valves and pipes for water conservancy facilities manufactured by the machinery factory.At the same time, it started to manufacture water pumps, supporting boilers and steam engines.

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 clean up the vegetation in the entire development area. The vegetation here is mainly small shrubs and weeds.The small shrubs are used as firewood, and the weeds and withered grass and fallen leaves are piled up in a few compost ponds temporarily built by Wu Nanhai after harvesting. Water, in the summer sun, will quickly decompose these plants into organic fertilizers.

If they are directly buried in the soil, some fibrous branches and leaves of plants and trees will not decompose even after many years, and will not play the role of fertilizing the field.

After clearing the vegetation, four bulldozers led by Armored Corps Commander Bai Yu arrived, all of which were Dongfanghong tractors equipped with bulldozing blades.Bai Yu poked his head out from the cab.Yan Quezhi and others had been waiting for him in 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 development area.Remove remnants of vegetation from the surface, and remove large rocks—the latter with particular care so as not to damage the dozer blades and tracks.Next to each bulldozer is a squad of army soldiers, who search in front of the bulldozer in a spread out formation.

"It's a bit like Butan cooperation." Yan Quezhi climbed on the cab and said to Bai Yu.

"If the oil and spare parts of the bulldozer can be used freely, I won't go to Beijing right away, why bother to open up wasteland and build roads here." Bai Yu stared at the front, constantly pushing and pulling the joystick in his hand.From time to time, he yelled on the intercom, asking other tractors to "pay attention to the distance between vehicles and maintain coordination."

"Tractor armored division?" Yan Quezhi immediately saw such a scene: the dirt road was billowing with smoke and dust, and the tracks of the Dongfanghong tractor, which could not be seen as far as the eye could see, were crushing the ground, and the tractor was full of so-called "tractor grenadiers" Riflemen, wearing bearskin hats, carrying minie rifles...

It feels so strange!Yanquezhi shook his head.

"Nothing is impossible." Bai Yu was full of confidence, "Mountain roads and water network areas are not good, but they are definitely a sharp weapon on the North China Plain. Look at this—" He pointed to a few people outside the cab. Protruding hardware - These appear to be an afterthought, not original to the tractor.

"What is this?" Yanquezhi asked loudly.

"The fixing part for hanging the armor plate." Bai Yu was very proud, it was designed and manufactured by himself, "When needed, the key parts of this tractor can be fully armed in half an hour, making it invulnerable. The bulletproof specification can withstand 6 A direct hit from a solid bullet from a pound cannon at a distance of 400 meters, is it strong enough?"

"Such a big iron ball hit directly, and the people in the cab were still so shocked that their mouths and noses were bleeding."

"The enemy has to be hit." Bai Yu didn't seem to be very worried about this. "Besides, we are not just sitting and being beaten. Look up."

On the top of the tractor, a car sunroof is newly opened, and there are things like slide rails around it.The sunroof is open, bringing some cool air to the hot cab.

"I made a modification kit, which can directly add a rotating turret to the roof part above the sunroof. Even if there is no machine gun, a 56 and a half can beat the enemy howling. If necessary, use grenades and grenades ——invincible.”

"What a creative idea—"

"What is this? I have studied weapon design and engineering design." The former armored officer was very proud. "There is also a fire-breathing tractor modification kit. Unfortunately, there is not enough fuel, and the executive committee refuses 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 a total of four "hand-held shotguns" on a heavy-duty agricultural bicycle commonly known as 28 bars, using the rapid maneuverability of the bicycle to launch close-in shots and harass the opponent's formation.Another modification is to install a fixed bracket for rifle shooting on the bicycle, which is used for the rider to shoot while riding the bicycle. By the way, this bracket also supports the pulley crossbow.

Generally speaking, the things designed by Bai Yu are relatively "modern". He scoffed at the things of the "retro school" weapon designers headed by Lin Shenhe.

After clearing, the waste soil excavated during the construction of the construction tide was transported from various construction sites.Yanquezhi is going to raise Meitaiyang as high as possible, even if it is [-] or [-] centimeters.This also incidentally disposed of a large amount of waste soil generated by construction everywhere.

All land leveling work will be completed soon.Then the tractor hooked up the heavy-duty plow for deep plowing to carry out deep plowing and plowing.A large amount of quicklime transported from Bopu was applied to improve the soil.The amount of lime used was such that the supply of quicklime on all construction sites was cut in half.In addition to working overtime in the quarry, all the off-duty personnel of the army and navy were mobilized to mine oyster houses on the coast to supplement the raw materials of burnt lime.

Yanquezhi's dam construction has also begun.Due to cost constraints, this dam uses a gravity earth dam with a simple structure, and multiple rows of wooden piles are driven into it for reinforcement.The periphery of the earth dam is covered with stones.The entire dam has a distance of more than 100 meters from the highest water level of the Wenlan River during the rainy season. Watermelon and peanuts.

Irrigation gates and drainage gates are set up on the dam to adapt to the arrangement of separate channels for irrigation and drainage.The gates are all opened and closed in a mechanized way, and the power for opening and closing uses the power of the steam pumping station on the embankment.

Connecting these two gates are two main channels, all of which are constructed of bamboo-reinforced concrete, with a sufficient margin in the design flow standard to meet the needs of irrigation and drainage in extreme environments.Other irrigation, drainage and branch canals in the field are connected to these two main canals, and the gates of the canals are equipped with manual opening and closing gates.

For the large amount of spring water flowing in from the hilly area, simply intercepting it with a drainage channel and discharging it into the Wenlan River is the easiest way to deal with it.But Yanquezhi believes that doing so is a waste of water resources.From the perspective of drought prevention, he decided to use the natural terrain to build ponds and dams in hilly areas to store water.The amount of construction of the pond and dam constructed in this way is small.The ponds and dams gather spring water to irrigate the 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 Crossover Group, and the amount of water used for industry and domestic use is not small.

The Tangba Reservoir built by using the natural terrain of the hills can not only adjust and store water, but also beautify the environment.Fish can be raised in the sugar dam to generate electricity.It's a feat.Wang Luobin has a lot of experience in building such a small water conservancy project, so he is the general contractor for this part of the project.

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

The basic construction of farmland water conservancy is going on vigorously.Wu Nanhai went to the executive committee to find Ma Qianju, asking him to help solve the fertilizer problem.

Because of the long-term waterlogging in the United States and Taiwan, the soil fertility is very poor.Applying lime can only neutralize acidity, but cannot improve soil fertility and trace element content.

Fa Shilu said: "The United States and Taiwan need to add a lot of nitrogen, phosphorus and potassium fertilizers. Especially phosphorus fertilizers. The phosphorus deficiency is so severe that you can't grow legume green manure. After the trace elements are adjusted, add farmyard manure. as base fertilizer."

The application of farmyard manure and green manure alone seems to be a large amount, but in terms of improving fertility, it is far less effective than the modern petty bourgeois chemical fertilizers.However, the ammonium nitrate they brought became the explosives of the Military Commission under the guidance of "military first politics".

"Nitrogen fertilizer is easy, let the Executive Committee find a way to get us lignite or peat. Phosphate fertilizer, potash fertilizer, where can I find them." Wu Nanhai muttered, "There is not so much bone meal."

"Lignite and peat are both good." Fa Shilu said, "Natural compound fertilizers contain nitrogen, phosphorus, and potassium, and the efficiency is much higher. However, the amount is not enough for soil improvement. It is best to have a special phosphorus fertilizer and potash."

For potash fertilizers, they can rely on the by-product of potassium chloride produced by the bittern industry in the refined salt factory to meet their needs.Coupled with the potassium contained in peat lignite, it is roughly enough.
