The rise of nanometers

After three days, the transformation of 120 acres of saline-alkali land in Zhangjiacun was finally completed.

Zhang Yaoguang arranged for the team leader Li Guoli to take the team to the next village, while he returned to the headquarters of the agricultural machinery rental company.

Lu Baojia and others from Fengmin Agriculture, who were responsible for the planning and planting of forage, and the agricultural machinery fleet of the agricultural machinery rental company also came to Zhangjia Village and began to prepare for the planning and planting.

In order to make it easier to come here, Lu Bao's family and several intern employees worked together to piece together the forty acres of pasture as much as possible to reduce the difficulty of management.

The agricultural machinery team used coated sand iron pipes and sand iron nets to surround the three patchwork pastures to prevent them from being trampled and eaten by livestock.

According to the previous division of each household, each household name plate is nailed on.

Based on the topography of the land, the Lu Bao family discussed with several intern employees and decided to plant sweet potatoes.

Since this is the first planting, the company's own agricultural machinery team can only take action. After all, those contracted farmers are generally skeptical and reluctant to invest energy in pasture.

The agricultural machinery team used machinery to excavate the soil, then planted sweet potato vines, and asked the water company to connect a water pipeline.

Water pipelines using new silicon nanotubes are not only half the cost, they are also effective in preventing theft and water theft.

To destroy silicon nanotubes, unless you use a large excavator to smash them hard, it will be difficult to connect them to the pipe. Even if you break a hole, it will be difficult to plug it.

When the water company connects its own water pipes, the interface is reserved and sealed with silicon nano-coating. When it is needed, a special ring is used to fasten it, and the interface is cut off through the oxygen-robbing effect of the six-cone ball. .

Ordinary people do not have the skills to cut through silicon nanotubes. If they have the ability to cut through silicon nanotubes, it can only be because the water company has a mole.

The water company has dedicated personnel on the pipelines. When internal and external collusion was discovered, Suiren Company's legal affairs were no joke.

After connecting the water pipe, a public tap was turned on.

"Lao Zhang, this is your water card. Insert it here and you can use water."

Zhang Youde was a little nervous and inserted the water card into the card reading slot.

The public faucet controller of the water company adopts a special design, is coated with silicon nano-coating on the surface, and is powered by solar panels internally, which greatly extends the service life.

On the LCD screen, a zero number popped up, which meant that Zhang Youde's water consumption was zero.

When I turned on the faucet, water began to flow out of the fire hose provided by the water company.

Several other farmers also tried it.

"Brother Du, how do you calculate this water?" Zhang Youde asked hurriedly.

Du Gaoke, a salesperson from Fengmin Agriculture on the side, explained to everyone: "For the grass you grow, you receive a ton of grass as a subsidy of 10 cubic meters of water, and the price is 30 cents per square; for the excess, the price is tiered..."

Du Gaoke came up with a ladder price for agricultural water.

1 to 100 cubic meters, 0.5 yuan per cubic meter; 101 to 500 cubic meters, 0.7 yuan per cubic meter; 501 to 2,000 cubic meters, 1 yuan per cubic meter; more than 2,000 cubic meters, 2.6 yuan per cubic meter.

This is the monthly water consumption.

An average wheat field requires 10 to 80 cubic meters of irrigation water per acre per season, vegetables require 220 to 550 cubic meters of irrigation water per acre per season, and cotton requires 30 to 100 cubic meters per acre per season.

According to the annual precipitation in the North China Plain, about 50% of the water needs can be met. Unless it enters a drought state, farmers will not easily use this kind of water that requires payment.

"The grass is sweet potato vine?" one of the old farmers asked.

Du Gaoke hurriedly said: "If you count sweet potatoes and sweet potato vines together, if you manage them well, you can harvest 10 tons of sweet potato vines and 6 tons of sweet potatoes per acre."

A group of farmers discussed in a low voice that many of them had grown sweet potatoes and could indeed achieve this yield, but the problem of the saline-alkali land made them a little worried.

With water and fertilizer subsidies, plus 200 yuan per ton, it is not a problem to earn two to three thousand per acre.

On the premise of being profitable, farmers became more motivated and secretly made up their minds to take good care of these sweet potatoes.

After all, each of their households has one or two acres planted with sweet potatoes.

Regarding the remaining renovated farmland, Zhang Youde and others plan to take a look at the situation. If the sweet potato seedlings can survive, then they will also plant sweet potatoes on these lands.

Anyway, the Fengmin Agriculture contract stipulates the purchase of pasture, but there is no provision to only harvest sweet potatoes from the pasture.

Even though the purchase price is only 200 yuan per ton, other subsidies are quite impressive.

For every ton of pasture purchased, farmers can receive 10 cubic meters of subsidized water, free choice of 90 kilograms of organic fertilizer, 20 kilograms of high-nitrogen organic fertilizer, and 15 kilograms of potassium fertilizer, and a 30% discount on the 100 kilograms of fertilizer quota.

Today's agricultural water is relatively cheap, but chemical fertilizers are different, averaging about 5 yuan per kilogram.

Equivalent to an additional fertilizer subsidy of 200 to 300 yuan per ton of forage.

In the era of 2009, this was a quite large subsidy, which greatly improved the income of farmers.

The land they had no way to use before can now be managed carefully, and they can harvest several thousand yuan per mu a year. With fertilizer subsidies, it also reduces the cost of planting other farmland. It can be said that it kills two birds with one stone.

At the same time that Zhang Youde and others were focused on transforming farmland.

With the arrival of the first batch of second-generation desalination trucks, the agricultural machinery rental company has received a total of 10 desalination fleets. This is the horror of large-scale production.

The second-generation desalination fleet, which has doubled its work efficiency, has been going to various villages to transform the contracted farmland.

As for the Lu Bao family, they were equally busy.

They need to plan the types of forage that farmers will plant and communicate well with farmers.

It can be said that the entire Fengmin Agriculture has been very busy recently. General Manager Xiao Yuan is also running around communicating with Blue Era and managing the increasingly large farms.

For many villagers in Zhangjia Village, this period of time has been more than a week with complicated emotions.

From the previous grazing contract to the transformation of saline-alkali land, many people were laughing at the joke, but since the sweet potato vines were inserted, they were slapped in the face.

For example, the old farmer who rejected Zhang Liehu before had his field not far from the saline-alkali land and passed by this area every day.

According to their thinking, not more than half of the sweet potato vines in this area can survive.

This is a common situation in moderately to severe saline-alkali lands. Even with sufficient irrigation, the survival rate of crop seedlings is only about 50%.

Even if salt-alkali tolerant varieties are used to improve the survival rate, the yield per mu is only about 20 to 50% of normal farmland. If it is a severely saline-alkali land, there may even be no harvest.

Zhang Youde, who was watering the vines, was also very surprised. After more than a week of slow seedling growth, many sweet potato vines had become vigorous and sprouted some small buds.

Seeing the old farmer walking past in a hurry, Zhang Youde shouted: "Old Ye, have the fields been plowed?"

Originally intending to pretend he didn't see it, Zhang Youye could only turn his head in embarrassment: "It's done, I'll go take a look at the wheat field."

After saying that, he ran away without looking back.

Looking at Zhang Youye running away, he smiled and shook his head. Regarding the gossip in the village, the farmers who signed the contract have been hearing the calluses for more than half a month.

According to Zhang Youde's many years of experience, the condition of these sweet potato seedlings is that they are growing very healthily. It is not yet known what the yield can be.

After watering, he turned off the faucet, pulled out the water card, and looked at the fields under the bright sun. He felt that this year was much drier than last year.
