Originally, when germinating seeds, a root thermometer should be placed inside, and the temperature should be strictly controlled between 25-32 °C.

But there was no thermometer in this era, but fortunately, Su Jinse was engaged in scientific research when he was in Huaxia, and he did a lot of scientific research, and the control of temperature was still very good, but it was not as accurate as the thermometer, but there would be no mistakes.

The germinated seeds should be checked every 3-4 hours, and they must be turned up and down to prevent the temperature from being too high to burn the seeds, and pay attention to the carbon fire in the small kang, so Su Jinse is busy, but she is hard, and she always gets up at night, and she sits directly in front of the small kang in the back and supports her little head and naps.

Zhang Tiezhu got up in the middle of the night, only to find that Bao'er didn't sleep, and was still standing in front of the small fire kang, this serious and firm attitude, even he sighed to himself.

He gently picked up Su Jinse, ready to carry her into the room and let her sleep on the bed, but woke up as soon as he touched her.

"Bao'er, good, go to the room and sleep." Zhang Tiezhu coaxed softly.

Su Jinse shook his head stubbornly, "No, I have to guard here." ”

"You go to sleep, I'll keep watch." Zhang Tiezhu said.

Su Jinse still stubbornly shook his head, "I must guard it, and I can't give up halfway." The key is the temperature control of this germination, and she is worried that Zhang Tiezhu will not be able to do it well.

Zhang Tiezhu saw that she didn't go to sleep, so he didn't sleep, moved a small bench for her, and sat in front of the small kang with her, after sitting for a while, Zhang Tiezhu was worried that she was hungry, so he specially made a bowl of noodle soup with flour and added two eggs to it.

After eating, Su Jinse felt a lot better.

Zhang Tiezhu watched carefully from the side, and gradually mastered a lot of knowledge, one father and one young father and daughter guarded the small fire kang.

Su Jinse couldn't hold it anymore, she fell asleep without knowing what to do while sitting, and when she woke up the next day, she was already lying on the bed, and the sun was big outside, so she knew that it was not early.

Oops, her corn seeds!

She hurriedly ran to take a look, only to find that her father had been guarding in front of the small kang and had been doing it according to her practice, and the temperature of the kang was just right.

Su Jinse couldn't help but breathe a sigh of relief, and felt a little happy in her heart, her father learned these things very quickly, and mastered the knowledge very quickly, in this way, she could be much easier, and she could also avoid many problems that were difficult to explain.

After three days, Su Jinse found that the corn seeds had sprouted!

Zhang Tiezhu was pleasantly surprised, "It's only been three days for these seeds to sprout!" That's a great way to do it! ”

He looked at the corn kernels he sprinkled in the soil every day, and there was no sign of germination at all.

Zhang Tiezhu hurriedly told Li Hongxiang the good news, and the two were overjoyed, and hurriedly sprinkled these sprouted corn kernels into the soil one by one.

Zhang Tiezhu decided to use this method to implement the remaining corn seeds, and planted two acres of land.

After the second batch of corn seeds were planted in the soil, the corn kernels he had sprinkled in the soil slowly sprouted, and the germination rate was not very high, only more than half of them germinated.

The time of the corn season is about 100 days, and Zhang Tiezhu and Li Hongxiang have been carefully serving every day in these 100 days.

Three months passed in a flash, and the corn was ripe in the blink of an eye.

Two acres of corn were harvested in several large baskets.

Zhang Tiezhu first sent some to several neighbors and Li Zheng and Xu Langzhong's families, and steamed coarse grain rice at home in the evening, with several corn steamed on it.
