The mud pools bubbling in the swamp are rich in all kinds of biogas bacteria that the digester needs to decompose plants, and collecting silt is essentially collecting bacteria.

The spotted cloth uses a 50-diameter hemp bamboo joint, one end of the hole, with a lot of effort to fill the silt, because it is too big and too heavy, Li Zhu helps to carry it.

Just one trip is enough.

Transported back to the mountains, poured into the biogas digester, the water was taken from the reservoir at the top of the mountain, watered in moderation, and some clay was collected from the bottom of the mountain as a medium for the culture.

Next, Zebra spends the whole day mowing grass in the mountains with a snakeskin bag.

Li Zhufeng, the bamboo forest that died due to drought last year, all kinds of bamboos used the last nutrients to separate flowers and seeds before dying, continuing the race. These seeds germinate and grow in the spring after a dormant period in autumn and winter.

At the same time, the seeds are scattered by the weeds in various ways, and the same takes root and sprouts and grows freely.

Since Zebra was planning to plant bamboo on a large scale, cutting weeds was a necessary job to ensure that the bamboo seedlings could grow smoothly.

The biogas digester can make use of weeds, which is a double win.

The grass is cut close to the ground, and the sharp toes like a sickle are gently hooked, so that they can be easily cut together at the roots, and then cut into small pieces and put into snakeskin bags.

Bag by bag is carried up the mountain, dumping the biogas digester, a small half of the pond can be, and the wellhead is blocked with a stone slab.

It took several days to cut all the weeds in the new bamboo forest on the mountain, collect the grass blades, and pile them up on the cliff for later use.

If the organic fertilizer obtained by the fermentation of the biogas digester has a significant effect on the promotion of plants, a large number of dead branches and leaves will definitely be used in the future.

……

The three primordial stones have indeed helped the growth of Zebra, alleviating the current lack of force intake, and entering the molting and evolving state nearly 10 days faster than expected.

The L9 junior warrior, with a body length of more than 60, has a greatly increased feeding capacity as the body grows, such as hares, which require two per day to eat.

Different from ordinary creatures, cockroach warriors have a large storage capacity for nutrients and energy, and they are full at one time and not hungry for a day. In the future, I will become a high-level warrior and have a full meal, and if I don't eat Force food, I can probably do it without eating for half a month.

……

The first batch of organic fertilizer from the digester is freshly baked.

Not ideally, after the plant decays and decomposes, a large amount of protein, especially the gas produced by the sulfur element, has a foul smell and is unpleasant.

However, it's much better than picking up animal manure or something.

Banbu first experimented with ordinary bamboo seedlings that looked relatively fragile, took swamp water for irrigation, and took swamp mud to fill the ground.

The comparative observation over a period of 5 days first confirmed that it would not harm the plants, and secondly, it was confirmed that it had a certain growth-promoting effect, which was not as significant as ideal.

Tiedaofeng took turns to take care of the four senior soldiers of Banbu, Li Zhu was the closest to Banbu, and he was also most interested in the biogas digester that Banbu tossed, and he had been observing the growth of the experimental bamboo poles for the past few days.

"Zebrabu, the effect is not as good as you say!"

Banbu thought for a moment and analyzed: "The soil of Li Zhufeng is the most fertile humus black soil, and the object of our experiment grows well enough, so we can't see the effect. ”

After all, Li Zhu is a high-level warrior, and he has rich farming experience, his brain is flexible, and he can understand a little, so he agreed: "That's right, we should choose relatively poor soil for experiments." ”

After speaking, Li Zhu added: "The growth of life seeds requires much more nutrients than ordinary plants, and the fertile land is easily barren, squeak, that, Zebra, why don't you try it with life seeds?" ”

Banbu's mind moved, and he clicked his tentacles, and said: "Li Zhu, I have a way, and I can immediately experiment whether the biogas digester fertilizer is effective." ”

The swamp water certainly doesn't smell like animal urine, and the swamp mud definitely doesn't smell like animal feces, but because cockroaches have a keen sense of smell, they feel that the smell is unacceptable.

Madara endured the stench, carried a bamboo tube of biogas slurry, and approached the god-given seed, anyway, it has been confirmed that it is harmless to plants, so it is safe to try boldly.

The god-given seed sensed Banbu's ill intentions and released his anger violently.

Banbu ignored it and poured the slurry directly under a branch.

The fierce anger of the god-given seed suddenly calmed down, and he was stunned for a moment, and then conveyed a disdainful and mocking thought to Banbu without being salty: You want to harm me? I'm sorry, but this thing is good for me, the more the merrier.

Plants don't have a sense of smell and don't feel the stench, and their roots are able to tell if the water is harmful or useful.

Banbu affirmed to Li Zhu: "It's really effective, it has an effect!" ”

Li Zhu asked, "Banbu, can you tell the difference between the god-given seeds?" ”

Madara preached: "Yes, it's its instinct, and it can't be wrong. ”

The temper of the God-given seed is due to plants, and if it is an animal, it is definitely the kind that jumps up and plays with life when it feels "ill-intentioned". Watering it with a bamboo tube of swamp water can soothe its irritable anger, and Banbu is very sure that the swamp water will help it grow.

Li Zhu said: "It's dark and sturdy, and it emits a foul smell, it doesn't look good, and it smells even worse." ”

"It's better than picking up animal droppings," Ban said. ”

"Yes, that's right." Li Zhu said with a smile: "Everyone doubts that Pu Tao's life seed is growing so well, is it secretly picking up dung, haha." ”

Zebrabu was speechless.

Everyone knows that animal manure is the best fertilizer, but that's disgusting, how can you do that kind of bad thing as a Red Cockroach Warrior.

Li Zhu stepped forward, dug open the surface layer of floating soil of a branch plant with the tips of his front paws, looked at it, and said: "Banbu, the demand for fertility of God-given seeds is higher than that of ordinary life seeds, you look carefully, the fertility of the soil has decreased. ”

Feeling that the soil of the branch was being cut and the root system was exposed, the god-given seed sent the idea of asking for help to Banbu in fear.

Banbu ignored it, stepped forward to look at it, and said, "That's right, I'll water all its branches." ”

After saying that, he flew to the north side of the mountain with a bamboo tube and drilled into the cave where the biogas digester had been opened.

The bamboo tube is opened at one end, punched holes, tied with hemp rope, thrown into the pool, filled with half a bucket, lifted up, carried, and flew back to the south side of the mountain.

At present, the total number of branches of the God-given seed is as many as 24, and Banbu is very patient to go back and forth 12 times, and each plant is watered in a small half tube.

With each round trip, the God-given seed sends a happy thought: it expresses satisfaction and satisfaction with Banbu's hard work and encourages him to continue his efforts.

Banbu didn't pay attention to this strange idea of the God-given seed at first, and was about to briefly explain the biogas digester making principle to Li Zhu after finishing his work, when the God-given seed came with the idea of urging and irritation.

Turning around, the first ramets had already absorbed the nutrients from the swamp water.

Horror absorption!

"It's gone."

Bambi sends a message to the God-given seed.

The God-given seed is still a message of urging and anger, with a clear meaning of blame.

Banbu suddenly woke up and understood a problem: the brain-dead dryad of the God-given seed seemed to have reversed the master-slave relationship! It treats itself like a servant coolie?

"My size, how do I dig a digester?" What do you think is the right location for Iron Knife Peak? Li Zhu was suddenly stunned when he saw Banbu, and called softly: "Banbu? ”

"Oh." Banbu said bitterly: "This brain-dead and mentally retarded, arrogant by nature, it seems that reasoning doesn't work!" ”

"Huh?" Li Zhu was confused, didn't know what to say, and called again: "Banbu? What are you talking about? ”

"Nothing, I suddenly realized a very serious problem." Banbu shook his head and said, "It's not a problem, don't worry, Li Zhu, come, I'll continue to explain to you the tricks of digging a biogas digester." ”
