Abstract:

 In order to explore the effects of sowing date and seedling nursery methods on seedling quality and yield of rice, an experiment was conducted, using early maturing hybrid rice variety Xinrongyou 6307 as material, two different seedling raising methods of geothermy dry nursery seedling in the greenhouse and mulch film with bamboo dry nursery seedling in the field were used, and four different sowing dates were set. The results showed that the treatment of geothermy dry nursery seedling in the greenhouse with sowing on March 15th has good seedling quality and high yield, and harvested 5 days earlier than the treatment of mulch film with bamboo dry nursery seedling in the field under the same sowing date. These results could provide theoretical basis and technical reference for high yield and high efficiency cultivation of rice.
