Abstract:

This study adopted a field comparative experiment, using four varieties, namely Guangmingjing 7, Ningxiangjing 9, Nanjing 9108 and Songzaoxiang 1, as materials. Six different harvest periods were set up for treatment to explore the impact of the harvest period on the rice quality of different rice varieties under the melon-rice rotation model. The results showed that the harvest period obviously affected the rice quality of different rice varieties. Among them, Guangmingjing 7 and Nanjing 9108 can achieve the best rice quality when harvested from October 15th to 20th, Ningxiangjing 9 can achieve the best rice quality when harvested from October 20th to 25th, and the control variety Songzaoxiang 1 can achieve the best rice quality when harvested from October 10th to 15th.

Key words: melon-rice water-dry rotation model, rice, quality, harvest period
