Effects of Seeding Amount on Rice Yield and Economic Benefits in Coastal Rice Region
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.
