Return to the countryside to engage in industry

Chapter 238 Fertilizer Conversion Device
Wang Chunyan was ready to go back after breakfast. Wang Xiuying was cleaning the dishes when she heard the engine of the trolley in the dam. She quickly put down the unfinished bowls. Take out the red envelope.

He stooped and ran out.

Yang Zhenyu and Wang Chunyan stood in front of the car door chatting.

Wang Xiuying ran up and said, "Chunyan, take it."

He raised Wang Chunyan's hand with his left hand, and put the red envelope in his palm with his right hand.

Wang Chunyan ducked subconsciously, "Grandma, no need."

Wang Xiuying said: "It's right for elders to give red envelopes to younger generations during Chinese New Year. Take it."

Yang Zhenyu echoed: "Just take it, grandma has already prepared it for you, and I will wait for you to come."

Wang Chunyan is very aware of the weight of this red envelope, not just the amount of money in it, but Wang Xiuying, as Yang Zhenyu's elder, a kind of expression to her.

It was really hard for her to refuse, so she accepted it with a smile, "Thank you grandma."

"No, no, no!" Wang Xiuying smiled and waved.

"Grandma, husband, I'm going back first." Wang Chunyan said goodbye.

"Slow down the road."

"it is good!"

The grandparents waved their hands.

Watching Wang Chunyan's car go away, Wang Xiuying asked Yang Zhenyu, "When are you going to visit her house for New Year's greetings?"

Yang Zhenyu smiled and said, "Grandma, it's still early, let's talk about it later."

Wang Xiuying looked like she hated iron for being weak, and reprimanded, "No matter how good the girl is, you will be yours only when you get married. Grandson, you are not young."

Yang Zhenyu smiled and said, "Grandma, even if you get married back in this society, it may not be yours."

This is true, the current divorce rate is so high, young people break up at the slightest disagreement, and there are countless divorces.

Yang Zhenyu thinks that if he waits a little longer, this way of getting along is quite good now.

Wang Xiuying squinted at him, shook her hands and said, "I don't like talking about you anymore."

Turned into the kitchen.

Yang Zhenyu knew why Wang Xiuying was in a hurry. He was afraid that he would be too old to say anything. If he got seriously ill or had an accident, he would leave and he would not see him get married and have children.

Sometimes when I think about these emotions, I feel guilty.

Just as he was thinking about it, the system screen popped up, pulling him back from his thoughts.

Yang Zhenyu smiled and said, "It's really time for you to come."

[Level of getting rich: 3]

【Get rich experience: 2500/3000】

【Working time: 2500h】

[Congratulations to the host for getting a lucky draw chance]

【whether to extract】

Yang Zhenyu clicks on the draw.

[Congratulations to the host for obtaining an advanced agricultural treasure box x 1]

The first two draws were advanced breeding treasure chests, this time it was agricultural treasure chests. Yang Zhenyu clicked to open the treasure chests.

[Congratulations to the host for obtaining the fertilizer conversion device]

A device that looks like a wet and dry separator appears on the screen.

This is the largest item that Yang Zhenyu has drawn out since he obtained the system.

The item information column at the bottom of the screen displays:
[Item: Fertilizer Conversion Device]

[Objects of use: animal manure, animal carcasses, vegetation...]

[Principle of action: organically treat objects such as animal manure to generate usable organic fertilizer. 】

[Instructions for use: Link interface or direct input]

After Yang Zhenyu read the information column, the first reaction in his mind was the wet and dry separator used in pig farms, which separates the water and dry matter of pig manure, and then uses fermentation to make pig manure a usable fertilizer.

This fertilizer conversion device is equivalent to integrating all the processes required for manure, and it is not only suitable for animal manure, but also for animal carcasses, plants, etc. After these things go in, they come out as organic fertilizers.

The process here is very complicated.

This machine is a very practical agricultural item.

With it, when building a pig farm, there is no need to build a septic tank, and there is no need to introduce machines such as dry and wet separators, which saves a lot of cost.

Pig manure itself is a very good fertilizer.

The rich humic acid in pig manure can promote the formation of soil aggregate structure, thereby improving the soil structure, making the soil loose and soft, enhancing permeability and water storage, and creating a good soil environment for crop growth.

Pig manure contains more nutrients, and its fertilizer effect is more comprehensive, and its fertilizer effect is stable and long-lasting.

In addition to containing a large number of nutrients such as nitrogen, phosphorus and potassium, it also contains more medium and trace element nutrients. More importantly, it also contains some substances that can stimulate the growth and development of crop roots and various beneficial microorganisms.It can not only provide nutrients for the growth and development of crops, but also effectively improve the soil, improve the capacity of fertilizer storage and water retention, and can well promote the absorption and utilization of chemical fertilizers, and improve the utilization rate of chemical fertilizers.

In addition, the content of humus in pig manure is the highest, and the rich humus has the strongest ability to retain fat. After being digested by the pig stomach, although the water content is more and the cellulolytic bacteria in it are relatively small, it is very suitable for microorganisms after excretion. The survival and reproduction of cellulolytic bacteria, especially the mass reproduction of cellulolytic bacteria, can accelerate the decomposition process of organic matter, thereby greatly increasing fertilizer efficiency.

However, pig manure that is not fully decomposed, that is, raw pig manure cannot be used as fertilizer.Because raw pig manure contains a large amount of undecomposed organic matter, the nutrients in it cannot be directly absorbed and utilized by crops.

Directly entering the soil, it will be further fermented, generate a certain amount of heat, produce harmful gases, and cause root and seedling burn.

Raw pig manure also contains a lot of salt, which can easily lead to salinization of the soil. When the salinization is severe, the seeds will not germinate. High concentration of salinized soil will cause the phenomenon of burning seedlings and roots.

There are more pathogenic bacteria, harmful insect eggs, weed seeds, and many heavy metals, antibiotics, etc. in the raw pig manure, which will not have adverse effects on crops after being directly applied to the soil, and it is easy to cause diseases, insect pests and weeds, and also affect the safety of agricultural products.

Therefore, raw pig manure must be fully fermented before it can be used as fertilizer.

In rural areas, pig manure is mainly fermented by high-temperature anaerobic fermentation, such as composting, which can kill most of the harmful insect eggs and weed seeds in a high-temperature anaerobic environment of 60°C to 70°C.

If a certain amount of biological bacteria is added, the fermentation speed can be effectively accelerated and the fermentation time can be shortened.

Fully decomposed pig manure can be used as a base fertilizer with chemical fertilizers to achieve organic and inorganic combinations, which can not only reduce the impact of chemical fertilizer residues on the soil, but also promote the absorption and utilization of chemical fertilizer nutrients.

According to calculations, one ton of pig manure is equivalent to 7 kg of ammonium sulfate 1, 21 kg of superphosphate, and 10 kg of potassium sulfate, so fully decomposed pig manure is a good agricultural fertilizer.

After the pig farm is built, it will produce a lot of manure. Now with this fertilizer conversion device, it can efficiently convert pig manure into fertilizer, and then use it for farming, eliminating environmental pollution and truly realizing the "food-wine-breeding The ecological agricultural structure of "pig-fertilizer-grain".

Yang Zhenyu put away his things, went into the house and took a pack of cigarettes, a box of tea, a piece of milk and a pot of oil to pay Zhang Mingkang a New Year's greeting, and by the way, discuss the matter of going to Zhejiang to inspect pig raising.
