Back in the lab, Chen Cheng called Huang Weidong to find out what the current backlog of urea in the dealers was, and whether it could be sold quickly through technical improvements.

Huang Weidong told him two things in a low mood.

First, Qian Da actually privately ventilated all agricultural product dealers in Hanxi Province, saying that whoever pressed Huang Weidong's payment for the longest time would have priority to get the discount quota of Huanong Group tomorrow.

Second, the autumn soybean planting rate in Hanxi Province this year is very high, and I thought that I could sell the inventory and recover the payment, but the recent dry weather may not sell urea.

The first piece of news was expected by Chen Cheng, after all, he had seen the despicable methods of Chanda.

It is not surprising that these tricks are used now.

On the contrary, it was the second piece of news that made Chen Cheng's eyes light up. If the drought will affect the market demand for urea, then the urea of other companies in the body will not be able to sell, including those of Huanong Group.

And he, as long as he solves this problem with technology, then this matter will be an opportunity for them.

"Tell me more about the autumn soybeans." Chen Cheng said.

Wang Kai, who was watching Ding Tao and their experiments on the sidelines, asked in surprise: "I have only heard of spring soybeans, how can I still grow autumn soybeans now?" ”

Huang Weidong, who was on the phone, explained to him: "The climate in our Hanxi Province can grow autumn soybeans, but the planting cycle is short, and urea needs to be applied once at the seedling stage. In other words, farmers will need a certain amount of urea this month. ”

Soybeans are generally planted in May and June, called spring soybeans, and can be harvested in September and October. Where the climate is suitable, you can plant soybeans, also known as autumn soybeans.

Soybeans, commonly known as soybeans, form some raised nodule structures due to the fact that their rhizomes parasitize rhizobia.

Rhizobia has a symbiotic relationship with soybean, and rhizobia can convert nitrogen in the air into nitrogen that can be absorbed by plants, providing nitrogen nutrition to soybean plants. Therefore, the amount of urea required in the soybean planting process is not much.

Spring soybeans generally only need to be top-dressed with 46% urea at the early flowering stage to supplement nutrients for flowering and fruiting.

However, in addition to the early flowering stage, autumn soybeans also need to apply urea once at the seedling stage. Because the rhizomes of the seedlings are not developed at this time, the rhizobia are not completely attached to the parasitism. Urea is applied to speed up its growth and development and shorten the planting cycle.

Although the demand for urea in the market at this time will not be too large, it is more than enough to eat the batch of urea that Huang Weidong and they squeezed last year.

Chen Cheng can learn this knowledge from the super agricultural system, but for Wang Kai, a scumbag, it belongs to advanced knowledge.

Huang Weidong sighed again: "The bad situation now is that the rain in Hanxi Province this autumn is insufficient, and the weather forecast will not rain in the next ten days, which may affect the fertilization of autumn soybeans." ”

Chen Cheng combined the knowledge he learned in the system and probably understood the current situation.

Autumn soybeans do need to apply urea, and there is a market demand. But the problem is that the weather is dry, which will affect market demand.

Because whether it will rain or not, farmers are most concerned.

They also know for sure that there has been no rain for a long time recently, and the most important thing for urea fertilization is rain.

Because urea fertilizer is applied to the soil, a small part is dissolved in the soil solution in a molecular state, and is adsorbed by the soil through hydrogen bonding. Most of the other is hydrolyzed into ammonium carbonate, which then produces hydrogen carbonate and ammonium hydroxide, and then NH4+ can be absorbed by plants and adsorbed by soil colloids, and NCO3- can also be absorbed by plants.

The most important thing here is water.

If there is a lack of water, the decomposition and absorption efficiency of urea will be reduced, and the growth promotion effect of soybean plants will be limited.

Autumn soybeans are competing to shorten the growth cycle, because pollination and fruiting will be affected when temperatures drop.

For farmers, soybeans are grown to sell for money, and in addition to labor costs, the biggest cost is the purchase of fertilizers and pesticides.

Nowadays, even if this urea is applied, the effect is not too good, so they would rather lower the harvest than risk spending money on fertilizer.

It's a very rustic idea and it's easy to understand.

"What are the autumn soybeans that farmers are growing now?" Chen Cheng asked.

Huang Weidong said: "Most of the new soybean seedlings in the planting area have broken the ground, about the size of four or five leaves. ”

People who specialize in the agricultural industry generally like to use the number of leaves grown by grass seedlings to indicate the growth status.

Four or five leaves are about to break through the soil and emerge six or seven centimeters tall small grass seedlings.

Huang Weidong said gloomily: "At present, autumn soybeans have been affected by dry weather, the growth of seedlings is slightly slow, if it does not rain, and timely replenishment of urea, I am afraid that farmers this year's autumn soybean harvest is hopeless." ”

"What is the mood of the peasants?"

Chen Cheng asked with a heart. In addition to selling urea, he is actually most concerned about the mood of the farmers.

They are the ones who are most worthy of connection.

Huang Weidong said: "I'm looking forward to the rain from God, hey! ”

Watch the sky and eat!

It's the 21st century, and the peasants still have to watch the sky for food.

Agriculture is too much to do with the weather, and it's not an industry where hard work pays off.

And Chen Cheng's duty as an agricultural researcher is to seek justice for the farmers.

Seek justice from God!

"Okay, I got it. Mr. Huang, don't worry, I will find a way to solve this problem as soon as possible. In addition, in the future, Wang Kai will be responsible for the company's business in my place. ”

"Okay. I await your good news. ”

Huang Weidong hung up the phone in frustration.

The weather is dry, this is God's business, a college student, although the technical strength is very good, but against the sky to change his life, he really did not have much hope.

After hanging up the phone, Chen Cheng gave Wang Kai an explanation.

Starting tomorrow, he asked Wang Kai to go to Hanxi Nongfeng Company to work for one day every other day to familiarize himself with the company's operation, market composition, and business rules as soon as possible.

In the future, everything related to business will be carried out and operated by Wang Kai on his behalf.

And he has to devote all his energy to scientific and technological research and development.

In order to make the hard work of the farmers have a harvest that matches it.

Back in the lab, Chen Cheng called up the system.

"Finding solutions to promote urea uptake by soybean seedlings in arid environments."

【Okay】

The supercomputer started running and gave the answer to the search in less than two minutes.

[According to the setting requirements, the method of artificially increasing the urease content in the soil can realize the rapid absorption of urea by soybean seedlings under drought conditions]

"Urease?"

Urease is a substance, he probably learned this knowledge when he studied in the system before.

Urease is a protease that is widely found in parts such as rhizomes and seeds of plants. Its biggest role is to break down urea.

The biggest role of urease is to catalyze the hydrolysis of urea into ammonia and carbon dioxide, and it is highly specific. What's more, in addition to the fact that plants themselves can produce urease, urease is also contained in the feces excreted by animals, and certain microorganisms can also secrete urease.

"It seems that urease is the breakthrough point to solve this problem!"
