比较了水稻免耕直播不同用种量、不同稻田处理、不同种子处理等20个处理的产量性状。结果表明,不同用种量对免耕直播稻有效穗、每穗总粒数、实粒数、结实率及产量有较大的影响;用催芽露白种子进行水稻免耕直播的最佳用种量为26.25kg/hm2,用旱育保姆包衣种子进行水稻免耕直播的最佳用种量为22.5 kg/hm2。
The yield traits of 20 treatments including no-tillage and direct-sowing of rice in different paddy fields, different paddy fields and different seed treatments were compared. The results showed that there were significant effects on the effective panicles, total grains per panicle, seed number, seed setting rate and yield of direct seeding rice with no-tillage seedlings. For 26.25kg / hm2, the optimum amount of rice for no-tillage direct-seeded rice was 22.5kg / hm2.
