Abstract:In order to find out the suitable sowing date for light,simple and efficient production of cotton and rape under rape cotton double direct seeding rotation mode in northern Jiangxi.The experiment set up 6 different rape sowing time treatments in northern Jiangxi from 2019 to 2020 to determine the growth and development indicators of each treatment,dry matter accumulation of each plant,yield and economic characters of rape,and explore the efforts of delaying the sowing date on the growth and development of rape within a certain range,dry matter accumulation per plant,yield and economic characters of rape.The results showed that the rape yield of T 1 treatment(sowed on October 17)was the highest,reaching 2701.95 kg/hm 2,which was 225.56%higher than that of T 6 treatment(sowed on November 21),the dry matter accumulation and yield per plant of T 1 treatment were significantly higher than that of T 5 and T 6 treatment,but the pod number per plant and 1000 grain weight of each treatment were not significantly different.In conclusion,under the premise of no significant negative impact on the growth and yield of rape,and considering the light,simple and efficient aspects of cotton harvesting and rape sowing,it is feasible to postpone the sowing date of rape to the end of October under the mode of rape cotton double direct seeding in northern Jiangxi cotton region.
Keywords:Cotton planting area of northern Jiangxi  Rape and cotton double direct seeding rotation mode  Rape  Sowing date
