Chapter 1126 Experimental Control Group
When Sun Shan arrived at the guano experimental base, Sun Dali, Sun Caogen, Sun Heitan and their group had already harvested the vegetables from one acre of the three experimental plots.
Sun Dali pointed at the green vegetables and said, "Master, look, this is without fertilizer, this is with ordinary fertilizer, and this is with bird droppings fertilizer."
A pile of green vegetables are neatly arranged, and you can tell at a glance which pile has more and which pile has less.
It's clear at a glance.
Sun Heitan sighed and said, "Master, there are many more vegetables that use guano than those that do not. Alas, you can't see it with your naked eyes, but when you compare them together after harvesting, you will know that there are far more vegetables that use guano as fertilizer."
Sun Caogen said in surprise: "Master, there are so many bird droppings in the hills behind Da Niao Village. If we use them to grow crops, won't we be able to harvest a lot more millet?"
Everyone got excited when they thought about the endless amount of bird droppings in Big Bird Village.
The bird droppings fermented in Sunshan can be used as fertilizer and do not burn the seedlings as the village chief of Da Niao Village said.
If it is used to grow rice, wouldn't the yield be much higher?
Sun Shan didn't say anything. He just asked Sun Dali to weigh the weight and asked Sun Dingnan to continue recording.
We also arranged for people to harvest vegetables from five mu of land and one mu of land, so that we could record and compare the data.
Sun Shan always likes to speak with data. It won’t work if he relies on estimation or imagination.
Sun Dalang asked doubtfully, "Master, we won't be able to eat all the harvested crops."
A person cannot eat all the food on one acre of land, but it can be fed to pigs. During the harvest, even the pigs cannot eat it.
The weather is getting hotter and hotter now. If the vegetables are left overnight, they will turn yellow and become inedible.
Sun Shan waved his hand without explaining, but said directly: "It's okay, just do as I ask."
After Sun Dali finished weighing the vegetables, he came up immediately and patted Sun Dalang gently.
He scolded: "Just do what the master tells you to do. Why bother asking so many questions? If you can figure it out, you will be the master."
After a pause, he continued to scold: "Humph, our master is the first Jinshi in Zhangzhou Prefecture, and he is also the smartest person in our Sunjia Village for a hundred years. His ideas are different from ordinary people. You won't understand even if I tell you. Anyway, do as the master asks, and don't think too much. Your brain is not clear."
Sun Dalang felt a little aggrieved when Sun Dali said this.
But what he said was true. If he knew why, he would be the first Jinshi in Sunjia Village.
Sun Shan quickly comforted him, "Some things can only be explained after they are done. You should listen to my instructions first, and then ask why."
Sun Dali nodded repeatedly in agreement and said, "Master is right."
The look was so flattering that Sun Shan's mouth twitched.
Sun Dalang was much more normal. He scratched his head and said honestly, "Master, I understand. If I still don't understand after I finish my work, I'll ask again. I'll finish the work first, and then we can talk about it."
Sun Shan nodded and smiled: "Okay, you guys start working first."
So the men harvested one mu of land, weighed it, and recorded it according to Sun Shan's request.
Harvest another five mu of land, weigh it, and record it.
Finally, harvest one acre of land, weigh it, and record it.
Sun Shan sat in the vegetable garden, watching the men busy at work, thinking that when the summer planting season came, he would use rice for experiments.
The method is the same as that of growing vegetables. Three groups of test fields are compared to see if the rice yield increases after using bird droppings.
In fact, according to Sun Shan's knowledge, using bird droppings would definitely increase production, but he had never done any experiments and was not at all reassured, fearing that the bird droppings would cause problems and be incompatible with rice.
To be on the safe side, it is still necessary to conduct experiments and proceed with caution.
Seeing Sun Shan frowning, Gui Ge'er asked worriedly, "Brother Shan, what's wrong with you? You seem unhappy?"
It is obvious that vegetables grown with bird droppings have a higher yield than those grown using conventional methods. This should be a good thing. Why is Brother Shan still not smiling?
Sun Shan shook his head and said, "It seems that the increase in production from using guano is not that great, alas."
I looked at the one-point data recorded by Sun Dingnan.
The yield from using bird droppings was not significantly increased compared to conventional planting methods, which was far from what one might have imagined.
When Gui Geer heard this, he immediately got angry and said disapprovingly: "Brother Shan, isn't this a high yield? It's one-third higher than the ordinary method, Brother Shan, it's much higher. Especially for the green vegetables that don't use any fertilizer, it's more than double. Brother Shan, let's not be too greedy."
Gui Geer pointed out that Sun Shan's idea was wrong. The output was obviously much higher, so how could it be said that it was not much?
In Sun Shan's opinion, the yield of both vegetables and millet is too low.
The correct output should be several times more than the current one.
Now it is only one third more, which is too little in Sun Shan's eyes.
But Gui Ge'er is right. Under limited conditions, it is already very rare to be able to increase production.
Sun Shan smiled and said, "Gui Ge'er, you are right. I was asking too much."
Seeing that Sun Shan agreed with him, Gui Geer said with a smile, "Brother Shan, you are different from us, so you have high standards. Haha, but being able to produce so much more is already very remarkable.
Brother Shan, don't ask for too much. Even if you ask for too much, you can ask for it later. Grandma said that you should eat your meal one bite at a time. You can't eat hot tofu in a hurry."
After saying this, he considerately offered Sun Shan some water and fanned him, looking like a typical servant.
Sun Shan took a sip of water. It was such a hot day that it was easy to sweat.
Then I looked at the man harvesting vegetables and felt that being a farmer was really hard.
Recalling my childhood, I was weak and didn’t want to farm, so I studied hard. After many twists and turns, I finally had to work around the land and eventually became a farmer.
Sun Shan smiled and said, "The rice in Yuanlu County is almost ready for harvest, and the rice in Huangyang County is almost ready as well."
Although the two places are quite far apart in terms of walking distance, the climate for growing rice is actually quite similar.
It was Huangyang County, but actually it was Sunjia Village. Gui Ge'er thought of Xiao Heimei and Li Jinhua.
Then he said, "Brother Shan, don't worry, the villagers are watching over our family, and the millet in the field will definitely be harvested in time."
Guiger's wages were not given to Li Jinhua, but to Su.
Let Su help him buy land.
However, Huangyang County has many mountains and few paddy fields, so it is extremely difficult to buy paddy fields. In the end, Su could only buy wasteland for Gui Ge'er.
As for what to plant on the wasteland, Gui Ge'er didn't know and left it all to Su.
His main task was to serve Sun Shan well, and everything else was put aside.
Sun Shan sat in the shade of a tree to enjoy the coolness. Sun Dali and others quickly harvested the vegetables and weighed them one by one. Sun Dingnan recorded them one by one.
Sun Dingnan said in surprise: "Master, please open it quickly. The yield of vegetables grown with bird droppings is much higher than that without bird droppings. Thank God, these bird droppings are really useful."
Sun Shan looked at the yields of one mu of land, five mu of land, and one acre of land and compared them. The three sets of data all concluded that the yield would increase by one third after using bird droppings.
These outputs seemed small in Sun Shan's eyes, but full of surprises in Sun Dingnan's eyes.
They are easier to satisfy than Sun Shan.
