There's a garbage bin in my head

Chapter 240 Building a Fermentation Pool
In fact, the residual hormones in these feces have the greatest impact on the fast-growing vegetables and fruits.

Therefore, many vegetables and fruits on the market are said to be grown with farmyard manure, which does not necessarily mean that they are green and pollution-free.

In today's society, pollution is actually everywhere, and this is probably the reason why Luo Jiu's garbage system appeared.

After buying those chicken, cow and sheep dung, Luo Jiu plans to use a robot to try to see if it can collect toxic waste in it.

The various residual hormone drugs in the feces should be classified as toxic waste in the garbage classification. As long as it is toxic waste, it is within the collection range of the robot, so Luo Jiu is a little bit concerned about the various toxic substances contained in these feces. Don't worry.

But apart from this point, there is the most important work to be done for these purchased feces. Only after this step is completed can they be used as fertilizer.

That is, these fertilizers need to be fully fermented before they can be used as fertilizers.

Farmyard manure that has not been fully fermented will slowly continue to ferment after being buried in the ground.

As long as the fertilizer is fermented, it will continue to emit heat, and when the heat reaches a certain level, it will have an impact on the saplings.

If it is mild, the saplings will suffer from various diseases. If the heat is too high, the saplings may be burned to death directly. This is the phenomenon of seedling burning that is often said in rural areas.

Sometimes too much fertilizer is used, especially urea is used too much at one time, and the problem of burning seedlings is most likely to occur.

Although the feces purchased from the chicken farms contacted were all said to have been fermented, Luo Jiu was still a little worried.

Luo Jiu knew that the excrement of the chicken farm was cleaned every day or every few days, and then put it in a fixed place to let it ferment naturally.

But because those manures are put in intermittently, the degree of fermentation is not the same at all. If they are bought and used directly, the fruit trees that are not fully fermented are likely to be burned to death.

Moreover, in addition to various hormones, those feces also contain a large number of various bacteria. If used directly as fertilizer, there is a high probability of causing the disease of the saplings, and ultimately the loss of the saplings.

Therefore, before fermentation, it is an essential process to sterilize the purchased chicken, cattle and sheep manure.

Moreover, during the fermentation process of feces, the temperature inside the piled up feces can reach 60-70 degrees, which can burn most of the bacteria.

During the process of manure fermentation, the water in the manure will also be released along with the heat, and the weight of the fermented fertilizer will be much lighter.

In addition to contacting the place to buy chicken, cattle and sheep manure yesterday, Luo Liyun also contacted several manure suction trucks in the town. As long as the chicken, cow and sheep manure is bought back, those manure suction trucks will pull the manure over.

These people were all acquainted by Luo Liyun when he was running a nursery before, and they were all from the same place, so there was no such thing as a disconnection.

But before the chicken, cattle and sheep dung can be bought back, Luo Jiu needs to build the fermentation tank for the dung fermentation first.

After these things are bought back, they are not simply piled up in the pool.

According to Luo Liyun, if these manures want to achieve the maximum efficiency of fertility, they need to be mixed together in a certain proportion, and it is best to add other simple fertilizers, such as potassium fertilizers, phosphorus fertilizers, and nitrogen fertilizers.

And before putting it into the fermentation tank, the fertilizer needs to be fully stirred evenly, and the fertilizer fermented at the end is the best.

When talking about this at the time, Luo Jiu almost vomited it out on the spot.

Although Luo Jiu also fried cow dung in the cow pen, stepped on chicken dung in the chicken coop, and raked pig dung in the pig pen when he was a child, when Luo Liyun talked about it while eating, Luo Jiu still felt To a bout of nausea.

When Luo Changqing drove the excavator and began to dig the pond, a "chug chug" sound came up from the bottom of the mountain, and the sound was getting closer and closer. Soon, a mobile car that is rarely seen even in rural areas now The tractor stopped not far from Luo Jiu.

Luo Liyun parked the car, walked to Luo Jiu's place quickly, looked at Luo Changqing who was driving the excavator to dig the pond, and said to Luo Jiu: "It's starting so soon, Brick has already agreed with Jing Er , and it will be delivered later.

At that time, the cement and sand will also be called Zhou Fei, who delivers bricks, to help pull it in. Zhou Fei is from the next door village. Everyone in the village builds houses and usually asks him to help buy sand and cement. He is more familiar with the sand sellers on the pier than us. It's cheaper to buy it yourself. "

Seeing that Luo Liyun had already arranged the materials, Luo Jiu asked: "Do you have the manpower to build the pond? If not, I'll ask someone to pull some people from the construction site to help.

Can those things be brought in today? If so, we will start building the pool tomorrow, and we will finish building the pool in two or three days. "

"Building a few pools is not a big project. Don't go to the construction site to call people. There are many people who can lay bricks in the village. I can call a few people at night."

In fact, the area of ​​the pond used for fermentation is only a little more than two cents. Luo Jiu roughly estimated that it is only about [-] to [-] square meters.

As for how to build the pool, Luo Jiu discussed with Luo Liyun yesterday, and they planned to build the pool with bricks all around to a height of about two meters.

Then it is divided into small fermentation tanks of different sizes and a dung storage tank.

The manure pulled by the manure truck will be stored in a specially prepared manure storage tank, and then mixed in and fermented with the chicken, cattle and sheep manure when it is needed.

In the afternoon of that day, all the materials for the construction of the pond were ready, and the pond, which was dug by two excavators since the afternoon, successfully dug out all the dead branches and leaves inside, and dug to the hard bottom below.

As for the excavated silt, it is also a kind of good fertilizer. For the time being, all of it is piled up around the pond. When the land is plowed later, the dug out silt will be put into the ground.

It was planned to build the pool in two days, but it took three days to build it.

However, Luo Jiu spared no expense in the construction, and the partition walls inside the pool were all made of iron walls, which required much more materials and time than ordinary partition walls.

Including the time for painting, it was the result of everyone's hard work to finish it in three days.

However, with such a pool, you don’t have to worry about any infiltration when you use it in the future, and there will be no problem for many years.
