A pond planting simulation experiment was conducted to explore the effects of film mulching direct seeding groove and different volume of mulch on soil temperature, seedling emergence rate and seedling quality, using indica conventional rice Zhongzao 39 as the test material. The results showed that the groove on the film and mulching increased the soil temperature and shorten the emergence time. Adding a certain amount of substrate coverage to the larger coverage improved seedling quality and dry matter accumulation. In the smaller coverage, the addition of the substrate had little effect on seedling quality. Under drill seeding conditions, the treatment of covering 205.9 mL of fine sand per 1 m resulted in uniform, faster of seedling emergence, and seedlings were stronger.
