After New Year's Eve.

The weather in Quancheng on the third day of the Chinese New Year is a bit clear.

It was rare for him to come to the branch library, Zhang Lei and others.

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

Looking at the back, it seemed like a girl with short hair and blue work clothes. Huang Xiuyuan, who was sharp-eyed, was a little surprised when he saw the book he was reading.

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

Huang Xiuyuan just took a look, then found a place by the window, and looked through it on his own.

The terrifying memory of the super memory was stimulated by him. He flipped the pages rhythmically, stopping from time to time to think about some problems.

Regarding the thinking on agricultural change, according to his previous ideas, there are still shortcomings in fertilizer subsidies, and reasonable price difference acquisitions are needed to be used and 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 domestic forage and forage grass are mainly Huangzhu grass, rye grass, alfalfa grass, sheep grass, Luzhou No. 1, feed vegetables, chrysanthemum lettuce, corn grass, etc.

The characteristics shown are also like many domestic industries. The varieties are mixed, the quality is uneven, the planting areas are scattered, and the distribution is mainly fragmented. Most of them are self-produced and sold by breeding. A few small companies are trying to plant on a large scale, but they are suffering from insufficient arable land.

After all, domestic arable land must maintain the planting area of ​​rice and wheat, so it cannot be used to plant forage, which is a natural contradiction.

He stood up and stretched.

He also went to get a few professional books on northern agriculture and the natural environment of the north. Huang Xiuyuan placed the land planted by the forage on those "useless lands".

The country has huge useless land, including saline-alkali land, sand land, and desert.

In the relevant papers of the Shandong Academy of Agricultural Sciences, there are about 5926.73 square kilometers of saline-alkali land in Shandong Province, of which there are about 3863.8 square kilometers of saline-alkali arable land used, and 2062.93 square kilometers of saline-alkali wasteland.

That is, the saline-alkali wasteland to be used in Shandong Province is 3.094395 million mu.

The saline-alkali wasteland in Hebei Province is about 3.225 million mu; the saline-alkali wasteland in Henan Province is about 4 million mu.

These three provinces in the North China Plain have 10 million mu of saline-alkali wasteland that have not been used. Together with those saline-alkali arable land, the total number is estimated to be around 25 million mu.

Although saline-alkali arable land can grow crops, the yield per unit per mu is very low, which may be less than half of the yield per mu than normal farmland.

These lands can actually be transformed into ordinary farmland again through transformation.

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

Huang Xiuyuan wrote down some key points on the page.

Land source - saline-alkali wasteland, semi-utilized saline-alkali cultivated land; saline-alkali land transformation technology, forage planting and cultivation, and the current operating model under the small peasant economy.

If you rely on simple administrative measures and financial subsidies, it will not be a long-term solution after all.

After some thought, he decided to establish an "Agricultural Bank", that is, a company that integrates acquisition, reserve, processing, sales, technology, fertilizer and equipment rental.

Sign a contract with farmers to transform the saline-alkali land held by farmers, and with fertilizers, water supply subsidies, and guidance on grass planting technology, the grass planted is purchased by the company, allowing farmers to actively plant grass.

After the company acquires the forage, part of it is supplied to the breeding farm's fresh poultry and livestock; part is deeply processed through green storage technology to serve as a strategic reserve for winter; part can be sold to the market.

According to relevant research, currently suitable for the promotion of forage, after discussing with Jiang Hailin and others, it was tentatively designated as sweet potatoes, feed vegetables, alfalfa, rye grass, and yellow bamboo grass.

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

The eighth day of the year.

Du Jinhua, who rushed from Shanmei headquarters and more than 50 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 from Dongying and is more familiar with the local situation."

"Hello, Mr. Huang." Xiao Yingnan didn't seem too reserved either.

When Huang Xiuyuan saw the familiar short hairstyle and could not forget it, he suddenly remembered the other person. It 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 off-road vehicles dedicated to security formed a convoy from Quancheng and headed towards Dongying.

On the minibus.

Huang Xiuyuan, Du Jinhua and Ma Changjiang were discussing some things. Ma Changjiang was an expert in saline-alkali land management that the company dug from the Shandong Academy of Agricultural Sciences.

Ma Changjiang said with a happy event on his face: "Mr. Huang, I have already learned about the company's technology in advance. If six-cone ball oxygen is used, the accumulated salt in the soil is extracted and the mixed soil transformation of organic fertilizer can fundamentally eliminate soil saline."

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

"That's true."

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

The group first settled in the Dongying branch and then went to the Dongying Dairy Cow Breeding Base.

On one side of the dairy cattle breeding base is the contracted pasture farm, with a total of more than 5,000 acres, which were previously medium and light saline-alkali land.

In the cold wind, there are ice chips on the ground beside the pasture, and some small weeds and shrubs that are cold-resistant and salt-alkali-resistant are growing here tenaciously.

Currently, North China has not entered the spring plowing stage. After contracting this land last year, the dairy cattle breeding base has no time to transform, and it is still deserted.

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

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

Du Jinhua's engineering team took action immediately.

Huang Xiuyuan, Ma Changjiang and others, tested the saline-alkali composition, content, depth, and humus content of the soil.

The ground was frozen hard, and the small drilling machine drilled the holes towards the direction, and it was more than three meters away.

The researchers conducted comprehensive tests on soils of different depths.

"The chloride content on the surface of the soil is around 0.6 to 1.4, and a small part is between 2 and 3, and the content is quite high."

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

"It is usually 30 to 50 cm of soil, but there is still a mineral salt layer at the bottom. After a long time, if the irrigation is unreasonable, it may be salinized again."

After saying that, he paused for a while and then said, "If possible, you can divide it into two parts, 50 cm of the surface is transformed into soil, and after removing the salt in the soil, add organic fertilizer to further improve it."

"The middle layer of soil is then turned down by 50 cm. This layer only removes salt, forming a buffer soil layer, separated from the salt layer below one meter."

Xiao Yingnan behind Huang Xiuyuan was holding a notebook and quickly remembering these contents.

"After adding the buffer layer, if the management is good, can it prevent saline and alkali from recurring?" Huang Xiuyuan sprinkled the handful of soil and stood up.
Chapter completed!
