Ten pennies a load? The yellow clay used to make a house costs five cents a load, and the dregs that can raise pigs are only ten cents a load? Wan Yuanwai looked at Ma Hanshan in disbelief. Mahanshan gave him an affirmative smile, and his eyes were a little foggy.

Wan Yuanwai was moved, but soon he figured out that this was Ma Hanshan's reward in disguise.

Alas, good man, this big child village owner is definitely a good person, Wan Yuanwai is sighing in his heart, suddenly from the field base came a little old man who looked like an old farmer, walking very fast, as approaching, it brought a breeze with a strange smell.

"The disciple grows grain and meets the teacher." The little old man who came in a hurry saluted Ma Hanshan, which turned out to be a great gift for the master and apprentice to meet, and the foggy eyes of the ten thousand people almost fell out, and their bodies shook and almost fell to the ground.

Disciple? Teacher? Oh my God, are the people in this tile pot village all crazy, is the owner of this horse village a monster, the livestock are raised in a pen, and the two-hundred-pound pig does not need to be used for two hundred days, and the strange hair is not a nondescript costume... A little old man who is dozens of years old, actually... Actually called a teenage child teacher?

"Grow food, the teacher has always taught you to pay attention to your appearance and demeanor, no matter what you encounter, you must maintain your image at any time, do you see that you have manners? Is there an image? How many days has this dress not been changed? Throwing a river can poison a river of fish. Ma Hanshan put his hands behind his back and solemnly reprimanded Chen Chongliang.

Well, after Chen Bonong came to the tile pot village, he felt that his name was simply beyond the master, and his own micro-end learning was not worthy of being called Bonong, he was a grain grower, so he changed his name to planting grain, Chen planting grain, he liked this life word very much, and his ideal was to grow good grain.

"Yes, the disciple remembers the teachings of the master." Chen Chongliang Station bowed his head and said.

"Hmph, every time I reprimand you, I do this, but I never change it, it's really disappointing for the teacher." Ma Hanshan accepted three disciples, and the most headache was Chen Chongliang, not only did he have a lot of problems, but the most annoying thing was that this uncle's personal hygiene was really frightening.

In fact, most of the people at the bottom in this world are like this, they have to eat without a meal, who has time to take a shower and change clothes? Besides, many people don't have that many clothes to change.

"Teacher, the disciple must change, the disciple swears to change ......." Chen Chongliang saw that Ma Hanshan was really angry, bowed again to admit his mistake, and vowed to correct it.

"Hmph, I'll listen first." Mahanshan raised his head, looked at the sky at forty-five degrees, and said, "Say, what's the matter?" ”

"Teacher, I adjusted the formula of compound fertilizer, No. 4 formula and No. 5 formula, which has a very great impact on cabbage, leeks and wheat seedlings. After fertilizing the wheat seedlings, it turned out that... It wilted. Chen Chongliang said like a child who had done something wrong, with his head down.

"Definitely, it must be that the nitrogen fertilizer is not fully ripe, or you use too much, take it with you to see." Ma Hanshan turned his head and glanced at Wan Yuanwai and said, "Wan Yuanwai, are you interested in visiting the fertilizer test base of our Agricultural Research Institute?" ”

"Fertilizer? What is it? Of course Wan Yuanwai is interested, an old man is called a teacher for a teenager, and he is very curious about what kind of fun he is doing.

"Hehe, fertilizer is the nutrition needed for crop growth, since everyone is interested, let's go and see it together." Ma Hanshan smiled.

He invited 10,000 people to visit, of course, not for show, but for the promotion of the organic mixed fertilizer made by the soil method to be launched next year.

Ma Hanshan understands the role of advertising too well, the information in this world is too backward, it is all passed on by word of mouth, and it is too necessary to promote it in advance.

The experimental fields of the Agricultural Research Institute are in the place where the sunshine is the most abundant and the water source is the best at the mouth of the valley, and the 100 acres of paddy fields and 100 acres of dry land have all been divided into plots of different sizes with signs on the ground.

Near the side of the hill, two small houses were built, which were not very well built, but were actually built with strong walls.

This is where the Agricultural Research Institute conducts fertilizer and pesticide preparation tests, and of course, the only test being conducted now is mixed fertilizer.

The concept and formula of mixed fertilizer are of course provided by Mahanshan. However, he really provided a concept, because he had never planted in his previous life, and he only had a little residual knowledge of the effect of nitrogen, phosphorus and potassium on crops, and he had no memory of the ratio of nitrogen, phosphorus and potassium in compound fertilizers.

For Chen Chongliang, even nitrogen, phosphorus and potassium were heard for the first time, so for what Ma Hanshan said, he was like a holy decree and never dared to question it, Ma Hanshan asked him to test again and again, he thought that this was a test for him by the teacher.

In an experimental field, a lot of cabbage, leeks and winter wheat were planted. Some of these cabbages, leeks and winter wheat are in good condition, with shiny dark green leaves, but like dwarf varieties, they are very filed, some are obviously "very tall", but very "slender", and some are wilting ....... As long as you have seen crops, you can see that these vegetables and wheat seedlings are not normal.

"Teacher, this ridge of wheat seedlings, this ridge of leeks and cabbage is applied to formula No. 4, and the three ridges here are applied to formula No. 5. Formula No. 4, wheat seedlings seem... It doesn't seem to work. Crops that use recipe five, as if... It seems to grow too fast, but it feels too delicate....... Chen Chongliang said with a bitter face.

For the nutrition of plants, after coming to the tile pot, he has a deep understanding, and now he also has a substantial understanding of the role of nitrogen, phosphorus and potassium. It turns out that, just like people, crops will eat and eat bad stomachs.

The fertilizer of the previous No. 12 and No. 3 formulas either reacted too slowly, or the crops were "filed", in short, it was not ideal, and the No. 4 and No. 5 formulas were the latest fertilizers prepared for old grains.

In fact, what fertilizer formula is said in this world, it is only a concept, because in this world, it is impossible to accurately determine nitrogen, phosphorus and potassium, and the so-called nitrogen, phosphorus and potassium in Mahanshan are made by soil method. Nitrogen is used as a source of nitrogen fertilizer after mixing and fermenting with fermented soybean water and soybean cake water (ammonium) after distiller's grains after steaming.

Phosphate fertilizer, on the other hand, is plant ash and various bone powders. Potash fertilizer is the potash salt, which was transported back by Mahanshan to the saline-alkali lake in the Western Regions. In fact, the phosphate rock that can be used as phosphate fertilizer has quite a large reserve in Guogai Mountain, and there is no way to find it in Mahanshan now.

He was going to send out to the island in search of guano after the year, and he remembered coming to the world, where there was an island country that specialized in phosphate, which was a natural high-quality phosphate fertilizer. By the way, I sent someone out to the sea to see if there were potatoes or sweet potatoes on those big islands.

"Grow grain, as the teacher said, to engage in agricultural research, whether it is to study species, seeds or soil, fertilizers or pesticides, you must be patient, to endure loneliness, how can you not get rid of the problem of impatience, now our nitrogen fertilizer is obtained by natural fermentation, so we must wait for it to complete fermentation before use. Also, the amount of wet and dry is not the same. Look, the No. 4 recipe is either a large amount, the crop is burned by ammonium, or the fermentation is not completed, and the roots are burned out after going down to the ground to absorb water. Either way, all three crops would have been destroyed. Ma Hanshan pointed to the wheat seedlings with wilting leaves and said.

"Teacher, the leeks are not wilting." Chen Chongliang said.

"Hmph, it hasn't wilted today, because its vitality is a little stronger than that of wheat seedlings, and tomorrow and the day after tomorrow, you see, it must be broken. There is also the No. 5 formula, which seems to be growing vigorously, but it is actually on the fat side. In other words, there is too little phosphorus and potassium in the formula, in this formula, are you reducing phosphorus and potassium and increasing the amount of nitrogen fertilizer? Ma Hanshan pointed to the No. 5 formula crop and said.

"Yes, teacher, I've lost half of my phosphorus and potassium......." Chen Chongliang bowed his head and said.

"Grow food, I said, I don't have time to give you a lesson, I hope you have to write it down every time we talk, because often conversation is teaching. As I said, nitrogen fertilizer multiplies; Potassium strengthens rhizomes; Phosphate fertilizer promotes flowers and fruits. If you prepare special fertilizer for some crops alone, you can pull the ratio of nitrogen, phosphorus and potassium apart from a large distance, otherwise, you should adjust the ratio of phosphorus and potassium on the basis of one to one to find the most suitable formula. Ma Hanshan pointed to the crops that seemed to be dwarfed but had thick stems and said, "Look, recipe No. 3 is actually close to OK, just a little less potassium or a little more nitrogen." ”

It's said that it is a river, what does it mean, everyone has a headache, and the owner of the village always says some strange words that they don't understand.

"Yes, Teacher." Chen Chongliang said with a red face.

"Well, let's try it slowly, as long as the formula can be determined by the end of next year." For this kind of homework that there is no way to copy, Ma Hanshan has always not treated it with the mentality of a traverser.

"Yes, Teacher." Seeing that Ma Hanshan was leaving, Chen Chongliang stepped forward and said, "Teacher, the ridge of green onions over there is very strange, I don't know if it's because of the mixed fertilizer." ”

"Oh? How weird? Lead the teacher to take a look. "Ma Hanshan doesn't like to study crops, but has just trained Chen to grow grain in front of thousands of people, his vanity is satisfied, his mood is very good, and he wants to continue to be a teacher.

The mutated green onion seedlings that Chen Chongliang said are actually green onions mixed with shallots. When Ma Hanshan saw the green onions, he remembered the sliced duck he liked to eat in his previous life, a single cake wrapped in crispy roast duck skin, add a few shredded green onions, and then spread some sweet sauce... Not... That's definitely delicious .......

Probably because there is no green onion variety in this world, Chen Chongliang feels weird.

"Hehe, grow grain, this green onion is nothing weird." Ma Hanshan said with a smile.

"Green onions? But this kind of green onion only grows stems and leaves but does not grow heads, and... The taste seems to be different from other green onions, and it is scary to be thick. Chen Chongliang frowned and said, because he hadn't seen it before, he thought it was weird.

"Yes, this is the green onion, grow grain, pull out the shallots mixed in it, and breed some seeds, this is a new variety, this green onion is popular in the north." Ma Hanshan was very happy, patted Chen Chongliang on the shoulder and said, "Okay, very good, the grain really lives up to the teacher's expectations, and new vegetables are bred so quickly, come on ......." ”

Yes? Come on? Why do you need to add oil to grow green onions? Is it another miracle fertilizer? Chen Chongliang was at a loss.

Ma Hanshan glanced at him and hurriedly said, "Come on" means hard work. wiped the corner of his forehead without a trace, and sighed secretly, alas, there is no word for refueling in this world, what if this goods take oil and green onions.
