Study on the Physiological Mechanism of Paper Tube Seedling Transplantation in Alleviating Herbicide Residue Stress in Paddy Soil and Promoting the Growth of Sugar Beet Seedlings
摘要
Abstract
[Objective]To explore the physiological mechanism of paper tube seedling cultivation in alleviating herbi-cide residue stress in paddy soil and promoting the growth of sugar beet seedlings.[Methods]Using the cultivated sug-ar beet variety"KWS7748"as the material,a pot experiment was conducted.Four treatments were set:bare soil direct sowing(T0),paper tube seedling cultivation and transplantation(T1),herbicide-stressed paddy soil paper tube seedling cultivation(T2),and herbicide-stressed bare soil direct sowing(T3).The growth indicators,photosynthetic characteris-tics,antioxidant enzyme activities,osmotic adjustment substances,and plant nutrient contents of sugar beet seedlings were measured.[Results]Compared with bare soil direct sowing,paper tube seedling cultivation significantly increased the plant height,stem diameter,leaf area,root area,and dry and fresh weight of sugar beet seedlings,improved the photosynthetic capacity of the plants,increased chlorophyll content and net photosynthetic rate;coordinated the antioxi-dant system,with the superoxide dismutase activity increasing,while the peroxidase,peroxidase and ascorbate peroxi-dase activities decreasing;the contents of proline,malondialdehyde,soluble sugar and soluble protein decreased,and the total nitrogen,total phosphorus and total potassium contents of the plants significantly increased.[Conclusion]Paper tube seedling cultivation effectively alleviated the stress of herbicide-stressed paddy soil on sugar beet seedlings through physical barrier effect,significantly improved the growth status of sugar beet seedlings,enhanced photosynthetic efficiency,antioxidant regulation ability and nutrient absorption efficiency,providing a theoretical basis for the safe pro-duction of sugar beet in paddy soil with herbicide stress.关键词
