Abstract
[Objective] The research aimed to provide the scientific cultivation basis for the grafted cotton in Jiangsu coastal areas.[Method]With sea island cotton Bima as rootstock and upland cotton Zhongmiansuo 75 as scions grafted cotton as material,the effects of different amount of fertilizer and different transplanting density on growth and yield of grafted cotton were studied.[Result] There was no significant effects on the growth of grafted cotton,but significant effects on the total yield of grafted cotton.Moderate increase in fertilization and rational close planting were helpful to improve seed cotton yield.[Conclusion] The highest seed cotton yield,lower rate of stiff flap cotton and higher rate of before frost cotton were gained when applying urea 931.5 kg/ha,NPK fertilizer 486 kg/ha,superphosphate 675 kg/ha and rapeseed dross 2 700 kg/ha and density 15 000 plants/ha.This combination is the reasonable cultivation fertilization amount and density of grafted cotton in Jiangsu coastal area.
