Preliminary Study on the Yield Components and Physiological Characteristics of Cotton Transplants in the Field by Using Floating Nursing Seedling in Water-bed Abstract：The effects of floating nursing seedling in water-bed(FNSW) on the cotton yield components and physiological-biochemical characteristics of transplants in the field were performed by using cultivar Nongza 66 as material. The results showed that the average plant height of cotton transplants was 9.1 cm higher, two to three more leaves grew on the main stem, two to three more fruiting branches developed, boll retention was 23.5% added, while the squares and bolls shedding were 3.4% reduced, compared with the control. The analysis of physiological and biochemical traits revealed that the activity of root system, the leaf chlorophyll, soluble protein and sugar content in cotton transplants were increased slightly by FNSW.
