The internal temperature in Ye Mo's greenhouse is 14 degrees Celsius.
Ye Mo just said a lot, but looking at Chen Chen's expression, he looked a little confused and asked: "Do you know what I meant by what I just said?"
"I probably understand." Chen Chen said with a slightly embarrassed expression.
I seem to understand, but I don't seem to understand.
Ye Mo glanced at him speechlessly: "Don't be obsessed with love. Pay more attention to your career and use your brain more. It's the end of autumn now. It's not difficult to talk about watermelons in this season... But thinking about it
It needs to be more mature. If it is not grown well in the first season, even if it can produce a second crop, the melons that come out will be crooked. The most important thing about mature melons is to take good care of the root system and main vine, and to keep the melon seedlings in a 'young' state."
While chatting, Ye Ran drove over in a car: "Brother."
"Why."
"What are you talking about?"
"I'm preaching to your boyfriend..." Ye Mo said.
Ye Mo doesn't like to preach to others, but Chen Chen is Ye Ran's boyfriend, and he is most likely Ye Mo's brother-in-law.
"What do you think he did?" Ye Ran said.
"I told him to pay more attention to the greenhouse and put more thought into it." Ye Mo said: "Don't be too impatient. Greenhouse watermelons like ours can be said to be delicate work, so you can't rush and think more. What's more,
When you have time, you can read more information on how to manage watermelons in greenhouses..."
"Hmm." Chen Chen was a little embarrassed and said, "Many of the melons over there are still clumps of seedlings, and the vines have not grown. The temperature dropped sharply yesterday, and when I went there in the morning, there were many watermelon leaves that were missing. Those seedlings were not developed.
, should I re-cultivate and colonize the seedlings?”
"Do those seedlings have roots? Hairy roots, roots... If there are only tap roots and no roots, it is most likely that the seedlings need to be replaced. If there are roots, you can wait and see." Ye Mo said: "It's better to plant melon seedlings.
Sometimes, if it is not transplanted properly and the roots are damaged... some of them will take more than half a month to recover."
"Did not notice."
"I'll go over and take a look at it for you."
Chen Chen nodded vigorously.
He had never grown watermelons himself, so he had no confidence.
At the beginning of the year, I helped Ye Mo manage the watermelons and thought it was very simple. But I could do it myself...
The seedlings Ye Mo gave to Chen Chen were those cultivated by Lingquan. Their vitality was stronger than ordinary melon seedlings. Even such melon seedlings were not well cultivated. No wonder Ye Mo said so to him.
Chen Chen has a lot of energy and works hard enough. He is still young and does not focus on the greenhouse.
Chen Chen seems to be only 23 years old.
Ye Mo himself just graduated from college when he was 23 years old. He is not sensible... the kind who can't save money even if he works outside.
Niu Yougui, Niu Youde, Tang Xun, Ye Zhi...
The melon seedlings they planted also died from the heat, but there are melon seedlings left and they will be fine after replanting.
Arriving at the gravel slope, Madam Xiaomian and the others were busy in the greenhouse, straightening the melon vines and fixing them on the shelves.
Ye Mo stopped the car and went over to take a look: "Ma'am, eldest uncle."
"Hey." Xiao Mian agreed and turned around to look over.
Ye Mo looked at these melon vines. The leaves of the melon vines were pointing downwards, not upwards.
"Didn't you heat the greenhouse last night?" Ye Mo said.
Niu Youde smiled awkwardly: "I forgot."
Ye Mo said before that it is almost impossible to use the heater at this time...
But the temperature dropped significantly last night.
"I'm going to Chen Chen to tell him about the temperature management of the greenhouse. Why don't you go over and listen too," Ye Mo said.
"Okay. I'll ask my second brother to come with us." Niu Youde immediately put down what he was doing.
Ye Mo went over and called Ye Zhi and Tang Xun...
The warehouses of Ye Zi and Tang Xun are not far away, and they have now moved to a greenhouse.
Ye Mo had told them about greenhouse temperature management before, and the two of them had placed the industrial fuel heater inside early and adjusted the automatic heating.
It rained lightly last night and the temperature dropped again...
It’s not a big drop in temperature. It’s rained a lot recently, and it’s only over ten degrees Celsius during the day... There was a cold wave last night.
Come to Chen Chen.
Chen Chen's parents are busy in the greenhouse. There are many seedlings in the greenhouse, which are still group seedlings. But there are more seedlings growing normally...
Ye Mo mainly talked about temperature management in greenhouses.
The temperature inside the greenhouse changes due to the influence of external environmental conditions and weather conditions, especially the temperature difference between day and night.
"The temperature difference between day and night here is very good. Especially in winter, the temperature difference between day and night is often more than ten degrees..." Ye Mo said: "During the day, if it is cloudy, the temperature in the greenhouse will rise slowly. But when the sun comes out,
, the temperature inside the greenhouse rises very quickly. When the sun comes out, the temperature outside the greenhouse is 20 degrees Celsius, so you have to pay attention to the temperature inside the greenhouse. When it is close to 25 degrees, you need to ventilate the greenhouse..."
Ye Mo said a lot, these... Tang Xun heard Ye Mo say before.
Tang Xun also told Chen Chen...
Inside the greenhouse, Ye Mo looked at Chen Chen's seedlings that had not yet grown and bloomed, and dug up the soil: "These seedlings do not need to be replaced, they have roots. For melon seedlings, the seedlings need to grow slowly until the female flowers bloom, and the greenhouse temperature is greater than 25 degrees.
Ventilate at all times, and close the air vents when it drops to 25 degrees in the afternoon. Keep the temperature above 12 degrees at night...don't take it seriously." Ye Mo saw Chen Chen looking left and right, and said: "At this stage, you will not be careless.
Big problems will arise. But after entering the flowering and fruiting period, if you are not careful, the initial investment will be wasted..."
"During the flowering and fruit setting period, the daytime temperature should be controlled at 25-30 degrees Celsius," Ye Mo said.
This temperature is an approximate value, anyway, just try to maintain it.
"The temperature at night is no longer 12 degrees, it should be kept above 15 degrees. When setting the heating, it is best to start heating when it is 17 degrees and stop when it reaches 19 degrees."
What you need to pay special attention to is the cold snap.
Ye Mo looked at the other seedlings that had not yet developed. Most of the seedlings had roots. It was just that these roots were not developed, but by keeping the temperature under control, it should not take long to recover.
"By the way, don't let in the ground wind when ventilating the greenhouse." Ye Mo said.
"What is earth wind?" Tang Xun asked.
"It just can't be ventilated from the ground." Ye Mo went outside the greenhouse, and a group of people followed him out.
The greenhouses they have here are designed so that the greenhouse membranes on both sides can be rolled up...
"If the greenhouse film is rolled up, it belongs to the local wind. If the greenhouse has a ventilation window, you can open the window, but you cannot roll up both sides of the greenhouse. If the ventilation effect is not obvious, use an exhaust fan. Don't be reluctant to spend these expenses." Ye Mo
Said: "There is also a heater, use it when you need to use it. Your heater consumes about 6 liters of fuel per hour. Even if it costs 40 yuan, it is driven for an average of 5 hours a day, which is 6,000 yuan a month. Still.
Including electricity bills and so on... the total is 8,000 yuan a month. As long as these watermelons are managed well and a batch is picked every month, a greenhouse of 1 acre can conservatively estimate a profit of 20,000 yuan. Watch more...
"Ye Mo said this mainly for Chen Chen.
"There is only a profit of 20,000 yuan per acre of greenhouse." Tang Xun said with a smile, "It's a bit less."
"A profit of 20,000 yuan is not bad. Your 17-acre greenhouse can produce more than 300,000 yuan in one batch. If you are conservative, you will have three mistakes..." Ye Mo said: "If you manage it with confidence, you can still keep 20,000 yuan."
melon."
"I have five greenhouses with only two vines left," Tang Xun said.
"Me too." Ye Zhidao said: "No matter how bold a person is, how productive the land is. I also took out 5 greenhouses to try..."
One vine and two melons in winter, and how ripe they are... Even if there is no spiritual spring, it is not impossible to achieve.
Ye Mo nodded and said: "I told you before that there are two vines in a plant. The two vines should be kept together to bloom and bear fruit. This is wrong."
"I know." Tang Xun said: "I am planning to ask you about this matter. I joined a WeChat group for winter greenhouse watermelons and asked other growers. They said that if one plant has two melons, they should be kept one after the other.
.The second melon can only be placed on the main vine after the watermelon has been established and has entered the expansion stage."
Ye Mo nodded: "I messed up before."
The watermelons in his place are irrigated by spiritual springs, and they are often used. The root system of the melon vines is very developed... let alone two melons growing at the same time, one melon plant can support the growth of five or six melons at the same time.
But it consumes a lot of money on the main vine and leaves too many melons, which are also smaller in size.
