1. I have been engaged in vegetable production practice and research for one year, and combined with my daily life and practical experience, I wrote the paper "One Crop of Vegetables a Year".

2. In the process of investigation, I deeply realized the importance of vegetable production to human life, and also found the existing problems and improvement schemes.

3. In the whole research process, I met many difficulties and challenges, but through continuous efforts and research, I finally got some research results.
