Chapter 372 368. New species is troublesome
The weather is so nice.

When Luo Yihang drove Qi Ruomu to the Deyang planting base, they happened to catch a rare sunny day in Sichuan and Chongqing.

There are two hundred acres of pea fields, stretching as far as the eye can see.

Under the sunshine, a sea of ​​​​emerald green appears.

The field was so vast that it seemed to stretch to the end of the horizon and connect with the sky.

Between the ridges of the fields, the pea vines are intertwined, linked together, hand in hand, and shoulder to shoulder.

The breeze blew, and the vines seemed to come alive. They swayed gently, making rustling sounds and whispering of a good harvest.

Luo Yihang has been farming for more than a year and now loves the green scenery everywhere.

I stopped the car and looked for a long time.

The two then drove back into the base park and made their way to the living area.

The living area of ​​this park is very small, just a row of red brick bungalows.

At the entrance, Shi Juan, Ling Tongjie, Luo Hongzhi, and the original owner of the planting base, Wang Shaopeng, who was also a graduate student taught by Professor Du and Qi Ruomu's junior, were already waiting to greet them.

According to traditional terms, Qi Ruomu, Ling Tongjie and others are considered inner disciples.

Wang Shaopeng is an outer disciple.

In fact, after graduation, he did not do scientific research, but started his own business.

Luo Yihang got out of the car and shook hands with the local host Wang Shaopeng first, "Mr. Wang, nice to meet you again."

Then take care of your employees.

It seems that they have had a hard time these days. Shi Juan and Luo Hongzhi have both lost weight, and their skin, which had been so white with great effort during the winter, has become several shades darker again.

"Shi Juan, you've worked hard. Let Chu Jie give you a good rest when we get back."

"Luo Hongzhi, you have worked hard and you have done a good job."

Ling Tongjie was on Qi Ruomu's side.

After meeting them all.

The landlord Wang Shaopeng invited everyone to go into the place where they usually ate, which temporarily served as a meeting room.

They are all young people, and they don't bother with red tape. After sitting down, they get straight to business.

Lecture by Shi Juan.

Let me introduce their experimental process over the past two months.

"When I first came here, Mr. Wang had already tidied up the fields. It saved me a lot of time." I thanked him in person.

"In the first batch, we planted 3 mu, of which mu were planted using the general sowing method, with only simple furrowing. The remaining mu used the three-ridge cultivation technique, dividing the land into three layers: ridge bottom, ridge body and ridge furrow. We also tried a different ridge-forming method every two mu, with widths ranging from to meters and spacings ranging from centimeters to meters."

"After trying it, I found that although the method of spreading nitrogen over large fields has the lowest cost, after measuring soil nutrients, I found that the nitrogen fixation effect in the middle area is poor. I suspect that this is due to the reduced carbon dioxide concentration in the dense legume environment."

"In the second round, I tried to reduce the input of nitrogen fertilizer, hoping to take advantage of symbiotic nitrogen fixation and improve nitrogen utilization efficiency, but I found that the effect was not obvious."

"However, considering the cost, spreading is the most economical method. The saved manpower and machinery costs can fully cover the additional fertilizer in the middle area."

"Ridge planting is more suitable for small plots..."

After that, there are purely manual planting methods, small-scale mechanical assisted methods, fertilization and supplementary fertilization intervals, fertilizer types, soil moisture requirements, and many more.

After Ling Tongjie and Luo Hongzhi came over.

Luo Hongzhi took on the work in the fields, while Ling Tongjie was able to share the soil experiments. Shi Juan started the second round of large-scale experiments.

100 acres are planted in general, 40 acres are planted in three-ridge cultivation that Shijuan has experimented with, and acres are planted with pure handwork.

It's really troublesome to cultivate a new species.

No wonder it is said that breeding varieties in the laboratory is just the beginning.

When we really enter the fields, we have to think about what planting methods to use, how to achieve the highest efficiency, how to balance yield and cost, fertilization, water control, temperature, and soil all have to be tested, and we have to do rounds of tests.

Moreover, what Shi Juan and her colleagues are doing now, even if successful, is only applicable to the planting methods in Deyang or the Sichuan Basin.

Change the place, change the mountains, change the plateau, change the water shortage or water abundance, change the climatic conditions, change the soil to poor or different acidity and alkalinity environment, and you have to start all over again.

Therefore, it may take four to five years, or even more than ten years, for a new variety to be successfully cultivated and promoted.

After planting comes harvesting.

It is definitely not possible to harvest 200 acres of pea tips manually, so Wang Shaopeng and Shi Juan modified a simple harvester. Shi Juan is indeed a versatile person who knows everything about agricultural machinery.

The principle is to lift the cutting knife and cut all the way at the corresponding height.

After the harvest is completed, the fruits are manually screened.

Even so, a lot of manpower is still needed.

Also, because pea tips are the tender shoots of peas, they are tender in texture and not resistant to storage and transportation. They are very easy to wilt, turn yellow and rot. Therefore, it is necessary to use HPLC dual-wavelength method to study the composition and activity of each part of the leaves, tendrils and stems, and calculate the storage and transportation time.

There are a lot of things to come.

That’s all about the difficulties.

Of course there is good news.

Great news.

The 200 acres of "Xiaoman No. 1" peas planted in the second round are growing very well and can be sold.

The current market price of peas in Sichuan Province is as high as 20 yuan per catty, and the quantity put on the market is extremely low, and they are sold out in seconds after they appear.

"Then how much can we produce?" Luo Yihang asked.

Shi Juan replied: "After calculation, the yield of the 280 mu of sowing in the second round was 380 kg per mu, and the yield of the 200 mu of ridged fields, including the 300 mu of intensive cultivation, was about the same, kg per mu. The yield of the mu of sowing in the first round was kg per mu, and the yield of the other mu of experimental fields varied, but the average was about kg."

“These are all single-crop data.”

While Shi Juan was talking, Luo Yihang was calculating with a calculator. In the end, he found that the average yield per mu of 300 mu was kilograms, and this was for one crop.

Qi Ruomu also figured it out, and he went a step further and calculated the selling price.

He exclaimed, "Twenty per pound, these two hundred acres can be sold for two million four hundred thousand! The average output value per acre is twelve thousand!"

Ling Tongjie turned his head and raised an eyebrow at his senior brother, smiling, "It's the output value of ten days. This thing can grow a crop in ten days. If you pay attention to fertilizing in the middle, you can harvest continuously. After ten to twelve crops, the main stem will age and the yield will decrease. You can dig it out and plant another round."

Qi Ruomu was even more shocked. "One crop is 12,000 yuan. One cycle is 10 crops, 120,000 yuan. One cycle is 100 days. If we plant two cycles, the annual output value is 240,000 yuan per acre?"

This thing is a vegetable, even a vegetable that is sown in the fields. The difficulty is about the same as growing wheat. Two hundred and forty thousand a year?
Ling Tongjie and Wang Shaopeng smiled at each other, and then laughed at the eldest brother together.

Seeing this, Luo Yihang pushed Qi Ruomu and said, "What are you thinking? Our pea yield is so high. Here alone, we produce 60 tons per crop. When the first crop is put on the market, the price will drop immediately."

Qi Ruomu slapped his forehead and forgot about the supply and demand relationship, which was knowledge he learned in high school.

He turned around and shifted the blame to others, glaring at his two junior brothers, "Have you two ever thought the same way?"

"Uh~~" They both turned their heads and looked elsewhere...
