增氧灌溉对土壤环境和棉花苗期耐盐性的影响
Effects of aerated irrigation on soil environment and salt tolerance of cotton seedlings
摘要
Abstract
In order to study the effects of aeration irrigation on soil environment and salt tolerance of cotton seedlings under different salt stress conditions,two irrigation water oxygen concentrations(conventional irrigation and aeration irrigation),four soil salinity gradients(0,0.3％,0.6％,0.9％)and two soil textures(loam and clay),a total of 16 treatments,each treatment was repeated 3 times,to study the effects of different treatments on soil salinity and physiological growth indexes of cotton seedlings,and to systematically evaluate the regulatory effect of aerated irrigation on cotton salt tolerance in saline-alkali environment.The results showed that aeration irrigation effectively inhibited the accumulation of soil salt in the 0-20 cm soil layer and promoted the migration of soil salt to the 20-40 cm soil layer.With the increase of soil salt concentration,aeration irrigation significantly affected the main ion content of the two soils,and the interaction between salt concentration,irrigation method and soil type played a key role in the dynamic change of ions.The dry matter mass of loam and clay increased by 12.40 mg and 18.37 mg,respectively.The superoxide dismutase(SOD)activity in leaves increased by an average of 23.70 U·L-1 and 40.98 U·L-1 in loam and clay soil,respectively.The peroxidase(POD)activity increased by an average of 31.44 mU·L-1and 28.82 mU.L-1,respectively.In contrast the content of malondialdehyde(MDA)decreased by 45.28 nmol·L-1 and 41.95 nmol·L-1,respectively.Studies have shown that aerated irrigation has a wide range of application potential in salinized areas.关键词
