摘要
以农杂66为材料，研究了棉花漂浮育苗对移栽棉株产量构成因素及生理生化特性的影响。研究结果表明：与营养钵育苗相比，漂浮育苗移栽棉的株高增加9．1cm，主茎叶数增加2～3片，单株有效果枝数增加2～3个，成铃数增加23．5％，蕾铃脱落率降低3．4％。生理生化特征分析显示，漂浮育苗能提高棉株的根系活力，使棉株叶片的叶绿素、可溶性蛋白质和可溶性糖含量增加。
Abstract： The effects of floating nursing seedling in water-bed（FNSW） on the cotton yield compo- nents 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.
