The person preparing to give a speech in the first lecture hall is Professor Chen Qihua who has just returned from the South Subtropical Crops Research Institute of the Chinese Academy of Tropical Agricultural Sciences. It has been four years since he went to South Asia to do research on hot crops, and today he is going to give you a popular science lecture on the research results of new hot crops.
The advertisement was typed out early, and it was posted on the only way to the cafeteria. Yang Heyu saw the four characters "macadamia nuts" on the handwritten newspaper at a glance.
In the first semester of freshman year, no professional courses were arranged. There are many materials in the library on the cultivation of hot crops, but there are not many related to macadamia nuts. At that time, this foreign species was still a marginal thing that was not valued in the land of China.
? Yang Heyu was suffering from not knowing who to ask for advice, so he bumped into this lecture, as if he was overjoyed when a drought meets rain.
The lecture had just begun when he arrived.
But out of Yang Heyu's expectation, not as many people participated in the listening as imagined. After observing the door, he ran to the front row and sat down.
At this time, Professor Chen also patted the microphone and said: "Oh, I have only been away for four years, and I have lost so many loyal fanciers!"
His humorous appearance made all the students in the audience laugh out loud.
"When I went to South Asia in 1990 to join the subject group of macadamia nuts, there were 8 high-spirited professors in our group. Then I lost two in one year, four in two years, and finally I was the only one left. People. It seems that I have such a cold temperament, a little lonely, right?"
The students in the audience laughed even harder, even Yang Heyu laughed out loud, but there was still a slight sadness hidden in his eyes.
"They all went to study lychee and mango, which is easier to produce results." Chen Qihua pushed his glasses, coughed twice, counted as the end of the hot field, and officially started the lecture.
Yang Heyu took out an old notebook from his backpack, which was a relic of his father. He opened some information about macadamia nuts that Yang Shiqing had recorded, and began to add later.
In a short two-hour lecture, Professor Chen Qihua gave a comprehensive and popular introduction to the characteristics of macadamia species, the current status of cultivation in my country, the future and problems.
From Professor Chen's narration, Yang Heyu knew that macadamia nuts were valued in Guangxi. Its planting development has been included in the Spark Plan by the South Subtropical Crops Development Office of the Guangxi Ministry of Agriculture. The planting area is close to 200 hectares. It is mainly planted in Huashan Farm and Jinguang Farm in the south of Nanning, and most of them have already blossomed.
Chen Qihua did not make the lecture very academic, he hoped to attract young people's interest through his narration. Finally, he left some time for interested students to ask questions.
Yang Heyu immediately raised his hand. He was sitting in the front row. Chen Qihua saw him at a glance and asked him to get up to speak.
"Professor, I would like to ask, what may be the reason for the low fruit setting rate of macadamia nuts?"
Yang Heyu asked this question very professionally. To Chen Qihua's surprise, he immediately asked: "How old is this classmate?"
"I'm a freshman, majoring in agronomy."
"Oh, why did you remember to ask this question?" Chen Qihua became even more interested in him when he heard that he was a freshman.
Yang Heyu replied: "I also have two macadamia trees at home. It has been ten years and they have not bear fruit, so I am very curious. I checked the information in the library, and I have not found any professional books on the species of macadamia."
Seeing that Chen Qihua's curious expression became more intense, Yang Heyu took the initiative to add: "My father used to be an employee of the Yunnan State-owned Farm. In 1984, he went to a lecture on macadamia nuts and got two saplings by chance." (Records Website website: www.hlnovel.com
