The rise of nanometers

After New Year's Eve.

On the third day of the Lunar New Year in Quancheng, the weather was a little sunny.

In a rare moment, he, Zhang Lei and others came to the branch library.

He looked at the row of books, found a few professional books that he was interested in, and walked to the reading room. As soon as he stepped into the reading room, he found someone reading.

Looking at the back, it seemed to be a girl with short hair and blue work clothes. Huang Xiuyuan, who had sharp eyes, was slightly surprised when he saw the book the other person was reading.

Because those were professional management books and law books, the girl did not notice his arrival because she was wearing thick Walkman headphones.

Huang Xiuyuan just glanced at it, then found a seat by the window and looked through it by himself.

The terrifying memory of the super-memory person was stimulated by him. He turned the pages of the book rhythmically, stopping to think about some questions from time to time.

Regarding agricultural reform, according to his previous thinking, fertilizer subsidies still have shortcomings, and reasonable price difference purchases need to be combined with fertilizer subsidies.

He has had several discussions with the industry analysis team led by Jiang Hailin in the past few days.

According to the current situation, the mainstream pasture and forage grasses in China are mainly emperor bamboo grass, rye grass, alfalfa, Leymus chinensis, Green State No. 1, forage vegetables, chicory lettuce, corn grass, etc.

The characteristics presented are the same as those of many domestic industries, with mixed varieties, good and bad varieties, scattered planting areas, and mainly fragmented distribution. Most of them are cultivated for self-production and sales. A few small companies are trying to plant on a large scale, but they suffer from insufficient arable land.

After all, domestic cultivated land needs to maintain the planting area of ​​rice and wheat, but naturally cannot be used to grow pasture. This is a natural contradiction.

He stood up and stretched.

After getting some professional books on northern agriculture and northern natural environment, Huang Xiuyuan placed the land for pasture cultivation on those "useless lands".

There is a huge amount of useless land in the country, which is undoubtedly saline-alkali land, sandy land, and desert.

According to a related paper by the Shandong Academy of Agricultural Sciences, the saline-alkali land in Shandong Province is approximately 5,926.73 square kilometers, of which approximately 3,863.8 square kilometers are utilized saline-alkali cultivated land and 2,062.93 square kilometers are saline-alkali wasteland.

That is, the saline-alkali wasteland to be utilized in Shandong Province is 3.094395 acres.

The saline-alkali wasteland to be utilized in Hebei Province is 3.225 million acres; the saline-alkali wasteland to be utilized in Henan Province is about 4 million acres.

These three provinces in the North China Plain have 10 million acres of unused saline-alkali wasteland. Including the saline-alkali cultivated land, the total is estimated to be about 25 million acres.

Although crops can be grown on saline-alkali farmland, the yield per mu is very low, perhaps less than half of that of normal farmland.

These lands can actually be transformed back into ordinary farmland.

For example, most of the dairy farms owned by the Suiren Company are built on saline-alkali land, and the contracted pasture planting areas are also on saline-alkali land.

Huang Xiuyuan wrote down some key points on the page.

Source of land - saline-alkali wasteland, semi-utilized saline-alkali cultivated land; saline-alkali land transformation technology, pasture planting and cultivation, and the current operating model under the small-scale farmer economy.

Relying solely on administrative measures and financial subsidies will not be a long-term solution after all.

After some thinking, he decided to establish an "Agricultural Bank", a company integrating acquisition, storage, processing, sales, technology, fertilizer, and equipment leasing.

Sign a contract with farmers to transform the saline-alkali land held by farmers, plus fertilizer, water supply subsidies, and guidance on forage planting technology. The grass grown will be purchased by the company, allowing farmers to take the initiative to plant grass.

After the company purchases forage, part of it is supplied to livestock farms as fresh food; part of it is further processed through green storage technology and used as strategic reserves in winter; part of it can be sold to the market.

According to relevant research, the varieties currently suitable for promotion as pasture grass were tentatively identified as sweet potato, fodder vegetable, alfalfa, ryegrass, and royal bamboo grass after discussions between him and Jiang Hailin and others.

The pilot area is tentatively designated as Dongying in Shandong Province, because Dongying has a large amount of saline-alkali land, which is just suitable for the pilot location.

The eighth day of the Lunar New Year.

Du Jinhua, who came from Shanmei headquarters, and more than fifty related researchers arrived in Quancheng.

Zhang Lei appeared in front of Huang Xiuyuan with a familiar figure: "Mr. Huang, this is Xiao Yingnan. She is a local in Dongying and is relatively familiar with the local situation."

"Mr. Huang, hello." Xiao Yingnan didn't look too reserved.

Seeing the familiar short hair style, Huang Xiuyuan, who had a photographic memory, suddenly remembered that the other person was the girl he met in the library that day.

"Then please ask Yingnan to lead the way."

"No problem." Xiao Yingnan nodded.

Several buses, minibuses, and security off-road vehicles formed a convoy and set off from Quancheng towards Dongying.

On the minibus.

Huang Xiuyuan was discussing something with Du Jinhua and Ma Changjiang. Ma Changjiang was an expert on saline-alkali land management that the company recruited from the Shandong Academy of Agricultural Sciences.

Ma Changjiang said with a happy face: "Mr. Huang, I have already had a preliminary understanding of the company's technology. If six-cone spherical oxygen is used to extract the accumulated salt in the soil, and the soil is mixed with organic fertilizer, it can be fundamentally improved. Eliminate soil salinity.”

"Let's test it on the spot." Huang Xiuyuan was still not sure.

"That's true."

During the discussion, the convoy finally entered Dongying City after several hours of driving.

The group first settled in Dongying Branch, and then went to Dongying Dairy Breeding Base.

On one side of the dairy breeding base is the contracted pasture, which totals more than 5,000 acres. It used to be moderately light saline-alkali land.

In the cold wind, the ground next to the pasture is still covered with ice, and some cold-resistant and salt-resistant weeds and shrubs are growing tenaciously here.

At present, North China has not yet entered the spring plowing stage. After contracting this land last year, the dairy breeding base did not have time to renovate it, and it is still there.

Not far away, a row of container houses are being built.

A large amount of mechanical processing equipment was purchased locally from Shandong Province, as well as large plowing tractors, excavators, etc. ordered from Yituo Group.

Du Jinhua's engineering team immediately took action.

Huang Xiuyuan, together with Ma Changjiang and others, tested the soil's saline-alkali composition, content, depth, and humus content.

The ground was frozen hard, and the small drilling machine drilled holes down more than three meters.

The researchers conducted comprehensive tests on soil at different depths.

"The chloride content in the soil surface is around 0.6 to 1.4, with a small amount ranging from 2 to 3. The content is quite high."

Huang Xiuyuan squatted down and grabbed a handful of sand: "Dr. Ma, if we want to complete the transformation, how deep do you think the soil should be turned?"

"Usually, the soil is turned over 30 to 50 centimeters, but there is still a mineral salt layer underneath. Over time, if irrigation is not reasonable, it may become salinized again."

After finishing speaking, he paused for a while and then said: "If possible, it can be divided into two parts. The surface layer of soil should be plowed and transformed to 50 centimeters. After the soil is desalted, organic fertilizer can be added for further improvement."

"The middle layer of soil is plowed down 50 centimeters. Only the salt is removed from this layer to form a buffer soil layer, which is separated from the salt layer below one meter."

Xiao Yingnan, who was behind Huang Xiuyuan, was holding a notebook and quickly jotting down these contents.

"After adding a buffer layer, if it is well managed, can it prevent the recurrence of salinity?" Huang Xiuyuan threw down the handful of soil and stood up.

Ma Changjiang thought for a moment: "If it is managed properly, it can be used for at least several decades. There is no problem."
