Winter is coming soon, and the winter in this southern city isn't too cold, and it doesn't even snow much. It's chilly at night, and it's a great time to validate greenhouse heating. When Zhao Anran renovated the greenhouse platform, he had already taken into account the experimental data of this time period. She moved the relevant experimental equipment into the greenhouse to test the data, and in addition to copying the data for data analysis, she also had to take care of the strawberry seedlings every day. Zhao Anran uses drip irrigation to water strawberry seedlings, each time it is necessary to regularly and quantitatively, and regularly add liquid fertilizer to strawberries to ensure nutrition. These methods are the result of many trials and consultations with strawberry growers.

Dr. Reda would occasionally pay attention to the strawberries and teach Zhao how to record plant growth data. The photovoltaic power generation he studied before was based on grid-connected real-time recording, and Zhao Anran's system is different from his, Zhao Anran uses off-grid photovoltaic power generation, which mainly applies electricity to the lighting at night and the circulation system of greenhouse heating. At the same time, Zhao Anran also has to pay attention to the heating of the water storage tank by the vacuum tube collector during the day, and sometimes, if the operation is not standardized, the vacuum tube is easy to burst.

All scientific research cannot be achieved overnight, and many times we are faced with the dilemma of failing the experiment and starting again, sometimes after a few days of hard work to collect data, there is no effective data that can be used after analysis. In addition, the growth of strawberries is an irreversible process, and the data of flowering and fruiting periods are different, which increases the difficulty of experimental research.

Throughout the winter, Zhao Anran spent the whole winter in anxiety, and finally ushered in the ripening of strawberry fruits. After picking the strawberries and performing various tests, the quality of the strawberry fruits in the heated greenhouse was higher than the reference value, and the results of this study also showed that the solar-powered greenhouse can provide better environmental factors for strawberry growth and development.

When Zhao Anran put the washed strawberries in glassware and sent them to Professor Li, Professor Li was overjoyed, quickly took out his mobile phone to take pictures, and asked about the relevant detection indicators, he smiled with satisfaction when he heard the results of Zhao Anran's analysis, and encouraged Zhao Anran to persist in this research to the end.

Approaching the Chinese New Year, the students in the laboratory are going home, and Zhao Anran still insists on waiting in the laboratory to collect a batch of strawberries for testing. Professor Li saw her and told her to go home as soon as she finished measuring the data. In addition, she was given two national fund application letters, and asked her to take them home to take a good look at them, and write a fund application with the solar greenhouse she studied according to the format.

After Zhao Anran received this important task, he felt a lot of pressure. She had never written an application for the National Fund, and even if she was given two samples to refer to, she didn't have much of a clue. She consulted Liu Hanlin, who instructed her to write the first part according to the idea of the paper review, and then discuss the subsequent parts with Professor Li after the first part was written. In fact, the most difficult thing about the fund is the innovation point, and innovation is the first element of scientific research.

Zhao Anran downloaded more than 50 references and took them home. During this period of preparation for the Chinese New Year, do not relax, read more and learn more, find out what the scholars have done and what they have not done, or what can be studied in depth on the basis of the predecessors. This is really a very brain-consuming and laborious work, and Zhao Anran can only start his studies after Huansha falls asleep after returning home, and sometimes stays up until two or three o'clock. She had postpartum hair loss, but she was faced with staying up late, which made her worry about whether she would become bald.
