Abstract
[Objective] To study effects of different sowing quantity on seedling quality and yield of machine transplanting rice. [Method]With Gangyou 6366 as test material,setting 50,70,80,90,110 g / disc 5 sowing quantities,using random block design,the relevant basic data during several key growth periods was investigated. [Result]The seedlings quality in less sowing quantity treatment is higher than that in high sowing quantity treatment,the basic seedlings of rice transplanting increased with the increase of sowing quantity,the rate of missing holes decreased,yield increased. [Conclusion] The optimum sowing quantity for machine transplanting hybrid rice is 80- 90 g / disc.
