摘要
为了完善滨海稻区直播稻高产栽培技术体系,2021、2022连续两年以不同水稻品种为材料,采用随机区组设计,不同年份不同品种设置不同播种量处理,测定播种量对直播稻生长发育及产量的影响,探索滨海稻区水稻旱直播最佳播种量.结果表明,旱直播两年的实际产量均以播量120 kg/hm2处理最高,分别为8.37、8.41 t/hm2,虽比当年的机插秧减产15.63％、15.73％,但效益分别增加 749.46、698.00 元/hm2.
Abstract
In order to improve the high-yield cultivation technology system of direct seeding rice in coastal area,d ferent varieties were used as materials under several seeding rates by random block test in 2021 and 2022 to deter-mine the impact of sowing rates on the growth and yield of dry direct seeding rice,and to explore the best sowi rate of direct seeding rice in coastal area.The results showed that both of the actual yields under 120 kg/hawere tl highest in two years,reached 8.37 t/haand 8.41 t/ha respectively.Although the highest yields were 15.63％and 15.73％lower than that of machine transplanting in the same year,the benefits increased by 749.46 yuan/ha and 698.00 yuan/ha,respectively.
