Five different seedling raising substrates were used to take the place of the nutrient soil to cultivate rice seedling mechanical transplanting in Anqing, Anhui Province. The emergence rate, survival rate, quality of aboveground parts of seedlings, root system and dry weight and fresh weight were surveyed and analyzed. The results showed that the rice seedling raising substrates could significantly improve the seedling quality and survival rate of mechanically transplanted seedlings, especially the seedling raising substrates produced by Anhui Province Lufu Agriculture Science and Technology Stock Co., Ltd. and Anhui Anqing Yike Seedling Material Co., Ltd. Finally, it is recommended to promote the seedling raising substrate in large area, to lay a solid foundation for realizing high yield, high quality, and high efficiency of rice. |
