"Dad, how can you burn seedlings?"

Lu Yangge listened to Lu Quan's words, and the whole person was shocked.

No wonder there are so many guano in this miscellaneous forest, because no one has ever thought that these guano can be used as fertilizer.

In the countryside, there are often ox carts, mule carts or donkey carts into the town, and Lu Yangge saw with his own eyes that the handle of the ox cart entered the town with a dung basket.

On the way, if his own oxen pull, he will cherish the cow and put it in the basket.

It's not that these old farmers have any concept of environmental protection, thinking that cow dung and pig manure will pollute the environment and affect the town's appearance.

It's that he is reluctant to waste these cow dung, so he picks them up and shoots them on the courtyard wall, and the cow dung can be used to boil the pot, which is a good fuel.

As for the pig manure and dog manure on the road, there will also be people picking it up.

When the farm is slack, there are often old farmers or children who carry a dung basket out to pick up dung, and then take a long-handled wooden spoon, walk all the way to find it, and see a stall of pig manure or something, which is like a treasure.

It is these farmers who take manure as a treasure that they don't know that guano is also the best base fertilizer for crops.

"It's just that they can burn seedlings."

Qiu Shi listened to the conversation between the two and also walked over, "I don't dare to use chicken feces at home, and grass grows easily, this bird dung is not similar to chicken feces." ”

"It's pretty much the same." Lu Yangge nodded, "However, you think that chicken feces and bird droppings can't be used because of burning seedlings, and it's easy to grow grass, right?" ”

"Yes, this is all the experience left by the ancestors, and it can't be wrong."

Lu Quanle patted the grass clippings on his body, "However, we still have to take a look at the guano pile you mentioned." Our family just moved in, not to mention livestock, not even a chicken. Your mother and your aunt just happened to be digging a vegetable field, so let's get some bird droppings to make base fertilizer, and dig less and mix it in the ground, which is still useful. ”

Qiu Shi also agreed: "You dig more and come back, mix it into the ground first, and I will water it more, and then plant the vegetable seedlings." It's okay to have a lot of spring grass next year, anyway, it's a vegetable field, and it's not big, just clean it up diligently. Most of the birds eat grass seeds, and the grass seeds pulled out fall to the ground and take root, and the grass is normal, as long as people are not lazy, they can also make the grass grow in the vegetable field. ”

"Daddy, listen to me first."

Lu Yangge was said by Lu Quan and his wife, and he didn't even have the time to interject. Seeing that they stopped, they hurriedly expressed their opinions.

"This bird droppings have grass seeds that are easy to burn the ground, in fact, it is very simple, as long as the fermentation is good, this bird droppings is a good thing. Not only does it not grow grass, but it also fertilizes the ground. ”

Can there be such a good thing?

Lu Quan and Qiu glanced at each other, and they were a little unconvinced. 、

Lu Quan: "What do you mean by fermentation?" ”

Qiu: "Can you really fertilize the land and not grow grass?" ”

"I said yes, for sure!" Lu Yangge answered Qiu with certainty, and then began to think about how to answer Lu Quan's question about fermentation.

She can't say that fermentation is the decomposition of complex organic compounds into relatively simple substances under the action of microorganisms.

If she said this, it was estimated that Lu Quan would have more questions waiting for her.

For example, what are organic compounds, what are microorganisms, what is decomposition, and so on.

"Dad, ferment all the manure and let it heat up naturally. Let's put it this way, just like my mother makes steamed bread cakes, if my mother makes steamed bread cakes directly with noodles, is the cake hard and unpalatable, and it will be heartburn if you eat too much? ”

Seeing Lu Quan nodding, Lu Yangge continued, "But if my mother puts the old noodles in it, and when the reconciled noodles grow, will the steamed bread cakes made be soft and refreshing, and I feel delicious when I eat them, and I don't feel heartburn when I eat more?" ”

Lu Quan nodded again, it is indeed like this. Dead dough cakes and live dough cakes are indeed a good taste, one is not delicious, and the dead dough cakes are not delicious and heartburn.

"Therefore, the old noodles put by the mother are called fermentation. We just pile up those bird droppings and chicken droppings, and then seal them in with silt for a year and a half, let them ferment in it like old noodles, and then the grass seeds in these bird droppings will be covered in the next year, and they will not be able to germinate, and because of such a long period of fermentation, the fertility of these bird droppings will also come up. Then pour it into the crop field, and the crops absorb the fertility, just like we eat old noodles and good steamed buns, and the seedlings will not be burned anymore. ”

Originally, it was a complicated question, but after Lu Yangge's analogy, not only Lu Quan understood, but even Qiu on the side understood.

Xiao Si is talking about the head is the Tao, so it must be that Xiao Si is right.

The small four families have thousands of tilts of fertile land, and the grain harvested every year has to be piled up into several hills.

Lujiazhuang also relies on the two mountains of Xiaoyun Mountain, which has more mixed forests and more guano.

The more Lu Quan thought about it, the more it made sense.

This child is smart, and she must have learned this from her father.

Thinking of those bird droppings, which will be scattered on the crops in the future, and thinking that the crops he planted will grow full ears of rice and wheat because of these bird droppings, Lu Quan's heart is as if he has drunk half a catty of grain wine, and he is a little drunk.

Seeing that Lu Quan pulled his legs and was about to go to Zhang San and them to discuss the matter of digging bird droppings, Lu Yangge grabbed Lu Quan: "Dad, I haven't taught you how to ferment yet." ”

Lu Quan asked suspiciously, "Didn't you say that it was sealed with mud and fermented?" ”

"Yes, that's true, but it's okay to ferment with bird droppings, you have to add something."

"Add what?"

"You also need to add things like deciduous straw, add water when it's dry, and add hay straw when it's wet, and it's best to seal it with that kind of black river mud, which is also very fertile."

"I understand, I understand." Lu Quan rubbed his hands excitedly, "It's just that it's going to ferment for so long, is there no fat in the ground this year?" ”

"Yes, how many years old are the bird droppings in the forest, let's dig out the bottom and use it, and drag the top back and pile it up to ferment." Lu Yangge patted his head as he spoke, "I'm stupid, the current guano probably doesn't need to be fermented, and there are already fallen leaves in the forest." Those bird droppings and fallen leaves are already fermented, and Dad only needs to dig a spade deep on the top when the time comes, and I guess the bottom one can be used. ”

Lu Quan kept nodding: "Well, I'll look for you and Zhang Sanbo and them now." We have to dig up the manure and pile it up, and we won't be able to keep it when others know about it. ”

After all, the miscellaneous forest is not theirs, it is a barren forest, and anyone can go there.

The reason why no one comes to the miscellaneous woods here is because it is too far away from the village, and there is wasteland except for the lake nearby, and the closest one is the field sold by the shopkeeper Li to the Lu family.

Lu Quan walked out and spoke: "I don't know how you Zhang Sanbo dug their holes." I just went to check it out. ”

"Holes?"

Lu Yangge's head was suspicious, didn't he say that he dug a few cellars by the way when he was digging mud and throwing adobe? How did it become a hole in the ground?

Does this cave mean the same as the cellar?
